In addition, in order to make the description clearer, compared with the actual state of the drawings, there are cases where the width, thickness, shape, etc. of each part are schematically shown, but the ultimate limit is only an example, and does not limit the interpreter of the present invention . In addition, in this specification and each drawing, there are cases where the same reference numerals are given to the same elements as those described in the drawings that have appeared, and detailed descriptions thereof are appropriately omitted.

(First Embodiment) First, the first embodiment will be described. Fig. 1 is an exploded perspective view showing a configuration example of an electronic device 100 of the first embodiment.

As shown in FIG. 1, the direction X, the direction Y, and the direction Z are orthogonal to each other, but they may cross at an angle other than 90 degrees.

The electronic device 100 includes a liquid crystal display device DSP as a display device, and a camera 1. The liquid crystal display device DSP includes a liquid crystal panel PNL as a display panel, and an illumination device (backlight source) IL. The camera 1 includes a camera (camera unit) 1a as a first camera, and one or more cameras (camera unit) 1b as a second camera. In this embodiment, although not all the cameras 1b are shown, the electronic device 100 includes seven cameras 1b.

In addition, the camera 1 may only include the camera 1a. Or, the camera 1 may only include a plurality of cameras 1b.

The lighting device IL includes a light guide LG1, a light source EM1, and a housing CS. This illuminating device IL illuminates, for example, the liquid crystal panel PNL shown in simplified form with a dotted line in FIG. 1.

The light guide body LG1 is formed in a flat plate shape parallel to the X-Y plane defined by the direction X and the direction Y. The light guide LG1 faces the liquid crystal panel PNL. The light guide body LG1 has a side surface SA, a side surface SB on the opposite side of the side surface SA, and a through hole h1 surrounding the camera 1a. The light guide LG1 faces the plurality of cameras 1b. The side surfaces SA and SB extend in the direction X, respectively. For example, the side surfaces SA and SB are surfaces parallel to the X-Z plane defined by the direction X and the direction Z. The through hole h1 penetrates the light guide body LG1 in the direction Z. The through hole h1 is located between the side surfaces SA and SB in the direction Y, and is closer to the side surface SB than the side surface SA.

A plurality of light sources EM1 are arranged at intervals in the direction X. Each light source EM1 is mounted on the wiring substrate F1 and is electrically connected to the wiring substrate F1. The light source EM1 is, for example, a light emitting diode (LED), which emits white illuminating light. The illumination light emitted from the light source EM1 enters the light guide body LG1 from the side surface SA, and travels inside the light guide body LG1 from the side surface SA toward the side surface SB.

The case CS accommodates the light guide LG1 and the light source EM1. The housing CS has side walls W1 to W4, a bottom plate BP, a through hole h2, a protrusion PP, and one or more through holes h3. The side walls W1 and W2 extend in the direction X and are opposite to the direction Y. The side walls W3 and W4 extend in the direction Y and are opposite to the direction X. The through hole h2 overlaps the through hole h1 in the direction Z. The protrusion PP is fixed to the bottom plate BP. The protrusion PP protrudes from the bottom plate BP toward the liquid crystal panel PNL in the direction Z, and surrounds the through hole h2.

In this embodiment, the housing CS has the same number of seven through holes h3 as the camera 1b. The through hole h3 is formed through the bottom plate BP in the direction Z. In a plan view, a plurality of through-holes h3 and through-holes h2 are dispersedly provided. In addition, in the case where the bottom plate BP is formed of a material for transmitting infrared light, the through hole h3 may not be formed in the bottom plate BP. In addition, from the viewpoint of reducing the thickness of the electronic device 100 in the direction Z, it is preferable to form a through hole h3 on the bottom plate BP, and to surround the camera 1b by the through hole h3.

The light guide LG1 overlaps the liquid crystal panel PNL.

The cameras 1a and 1b are mounted on the wiring board F2, and are electrically connected to the wiring board F2. The camera 1a passes through the through hole h2, the inside of the protrusion PP, and the through hole h1, and faces the liquid crystal panel PNL. The camera 1b faces the light guide LG1 through the through hole h3.

2 is a cross-sectional view showing the periphery of the camera 1a of the electronic device 100.

As shown in FIG. 2, the lighting device IL further includes a light reflection sheet RS, a light diffusion sheet SS, and 稜鏡 sheets PS1 and PS2.

The light reflection sheet RS, the light guide LG1, the light diffusion sheet SS, the scallop sheet PS1, and the scallop sheet PS2 are sequentially arranged in the direction Z, and are housed in the housing CS. The case CS is provided with a metal case CS1 and a resin-made light shielding wall CS2 as a peripheral member. The light-shielding wall CS2 is adjacent to the camera 1 and forms a protrusion PP together with the housing CS1. The light shielding wall CS2 is located between the camera 1 and the light guide LG1, and has a cylindrical shape. The light-shielding wall CS2 is formed of light-absorbing resin such as black resin. The light diffusing sheet SS, the scallop sheet PS1, and the scallop sheet PS2 have through holes overlapping with the through holes h1, respectively. The protrusion PP is located inside the through hole h1.

The liquid crystal panel PNL further has a polarizing plate PL1 and a polarizing plate PL2. The liquid crystal panel PNL and the protective glass CG as a cover member are arranged in the direction Z to form a liquid crystal element LCD with an optical switch function for light traveling in the direction Z. The liquid crystal element LCD is attached to the lighting device IL with an adhesive tape TP1. The tape TP1 is adhered to the protrusion PP, the 稜鏡 sheet PS2, and the polarizing plate PL1.

The liquid crystal panel PNL can have any configuration corresponding to the following modes, namely: a display mode using a transverse electric field along the main surface of the substrate, a display mode using a vertical electric field along the normal to the main surface of the substrate, and a display mode using The display mode of the oblique electric field that is inclined in the oblique direction, and the display mode used by appropriately combining the above-mentioned horizontal electric field, vertical electric field, and oblique electric field. The main surface of the substrate here is a surface parallel to the X-Y plane.

The liquid crystal panel PNL includes a display area DA for displaying images, a non-display area NDA outside the display area DA, and an incident light control area PCA having a circular shape surrounded by the display area DA. The liquid crystal panel PNL includes a first substrate SUB1, a second substrate SUB2, a liquid crystal layer LC, and a sealing material SE. The sealing material SE is located in the non-display area NDA, and joins the first substrate SUB1 and the second substrate SUB2. The liquid crystal layer LC is located in the display area DA and the incident light control area PCA, and is held between the first substrate SUB1 and the second substrate SUB2. The liquid crystal layer LC is formed in a space surrounded by the first substrate SUB1, the second substrate SUB2, and the sealing material SE.

An image is displayed in the display area DA by controlling the amount of light irradiated from the lighting device IL through the liquid crystal panel PNL. The user of the electronic device 100 is located on the direction Z side (upper side in the figure) of the protective glass CG, and regards the light emitted from the liquid crystal panel PNL as an image.

On the contrary, in the incident light control area PCA, the amount of light transmission is also controlled by the liquid crystal panel PNL, but the light enters the camera 1 from the direction Z side of the cover glass CG through the liquid crystal panel PNL.

In this specification, light from the lighting device IL toward the side of the cover glass CG via the liquid crystal panel PNL is referred to as emitted light, and light from the side of the cover glass CG toward the camera 1 via the liquid crystal panel PNL is referred to as incident light.

Here, the main parts of the first substrate SUB1 and the second substrate SUB2 will be described.

The first substrate SUB1 includes an insulating substrate 10 and an alignment film AL1. The second substrate SUB2 includes an insulating substrate 20, a color filter CF, a light shielding layer BM, a transparent layer OC, and an alignment film AL2.

The insulating substrate 10 and the insulating substrate 20 are transparent substrates such as a glass substrate or a flexible resin substrate. The alignment films AL1 and AL2 are in contact with the liquid crystal layer LC.

The color filter CF, the light shielding layer BM, and the transparent layer OC are located between the insulating substrate 20 and the liquid crystal layer LC. In addition, in the example shown in the figure, the color filter CF is provided on the second substrate SUB2, but it may be provided on the first substrate SUB1. The color filter CF is located in the display area DA.

The incident light control area PCA has at least a first light shielding area LSA1 located at the outermost periphery and having the shape of a ring, and a first incident light control area TA1 surrounded by the first light shielding area LSA1 and in contact with the first light shielding area LSA1.

The light-shielding layer BM includes a light-shielding portion located in the display area DA and partitioning pixels, and a frame-shaped light-shielding portion BMB located in the non-display area NDA. In the incident light control area PCA, the light shielding layer BM includes at least: a first light shielding portion BM1 located in the first light shielding area LSA1 and having a ring shape, and a first opening OP1 located in the first incident light control area TA1.

The boundary between the display area DA and the non-display area NDA is defined by, for example, the inner end of the light shielding portion BMB (the end on the display area DA side). The sealing material SE overlaps the light shielding portion BMB.

The transparent layer OC is in contact with the color filter CF in the display area DA, in the non-display area NDA, in contact with the light shielding portion BMB, in the first light shielding area LSA1, in contact with the first light shielding portion BM1, and in the first incident The light control area TA1 is in contact with the insulating substrate 20. The alignment film AL1 and the alignment film AL2 are provided throughout the display area DA, the incident light control area PCA, and the non-display area NDA.

Although the details of the color filter CF are omitted here, the color filter CF includes, for example, a red coloring layer arranged on red pixels, a green coloring layer arranged on green pixels, and a blue coloring layer arranged on blue pixels. The blue color layer. In addition, the color filter CF may also have a transparent resin layer arranged on the white pixels. The transparent layer OC covers the color filter CF and the light shielding layer BM. The transparent layer OC is, for example, a transparent organic insulating layer.

The camera 1 is located inside the through hole h2 of the housing CS. The camera 1 overlaps the protective glass CG and the liquid crystal panel PNL in the direction Z. In addition, the liquid crystal panel PNL may further include optical sheets other than the polarizing plate PL1 and the polarizing plate PL2 in the incident light control area PCA. As said optical sheet, a retardation plate, a light scattering layer, a light reflection prevention layer, etc. are mentioned. In an electronic device 100 having a liquid crystal panel PNL, a camera 1a, etc., from the perspective of a user of the electronic device 100, the camera 1a is installed on the deep side of the liquid crystal panel PNL.

The camera 1 a includes, for example, an optical system 2 including at least one lens, an imaging element (image sensor) 3, and a housing 4. The imaging element 3 includes an imaging surface 3a facing the PNL side of the liquid crystal panel. The optical system 2 is located between the imaging surface 3a and the liquid crystal panel PNL, and includes a light incident surface 2a facing the liquid crystal panel PNL. The light incident surface 2a overlaps with the incident light control area PCA. The optical system 2 is located on the liquid crystal panel PNL with a gap. The housing 4 houses the optical system 2 and the imaging element 3.

On the upper part of the housing 4, a light source EM2 as a first light source and a light source EM3 as a second light source are arranged. The light source EM2 is configured to emit infrared light toward the liquid crystal panel PNL side. The light source EM3 is configured to emit visible light toward the liquid crystal panel PNL side. The light sources EM2 and EM3 are set for the purpose of illuminating the subject photographed by the camera 1a.

The imaging element 3 of the camera 1a receives light through the cover glass CG, the liquid crystal panel PNL, and the optical system 2. For example, the camera 1a receives visible light (such as light in the wavelength range of 400 nm to 700 nm) transmitted through the protective glass CG and the liquid crystal panel PNL. In addition, infrared light (for example, light in the wavelength range of 800 nm to 1500 nm) can be received simultaneously with visible light.

In addition, the camera 1b is different from the camera 1a in that it does not have the light source EM3. The camera 1b opposes the light reflection sheet RS through the through hole h3 (FIG. 1). The camera 1b can receive infrared light through the cover glass CG, the liquid crystal panel PNL, the scallop sheet PS2, the scallop sheet PS1, the light diffusion sheet SS, the light guide body LG1, the light reflection sheet RS, and the optical system 2. The reflective sheet RS has a hole in the light reflective sheet at a position overlapping with the IR sensor. However, when the light-reflecting sheet is a film capable of transmitting IR, the light-reflecting sheet does not need to be opened, and an IR sensor can also receive the infrared light transmitted through the light-reflecting sheet. In this case, the adverse effect on the visibility of the image can be reduced. In addition, the camera 1b may be housed in the through hole h1 of the light guide body LG1 and the through hole h2 of the bottom plate BP in the same manner as the camera 1a.

The polarizing plate PL1 is attached to the insulating substrate 10. The polarizing plate PL2 is attached to the insulating substrate 20. The protective glass CG is attached to the polarizing plate PL2 through the transparent adhesive layer AD.

In addition, in order to prevent the liquid crystal layer LC from being affected by an external electric field or the like, a transparent conductive layer may be provided between the polarizing plate PL2 and the insulating substrate 20. The transparent conductive layer is formed of transparent conductive materials such as indium tin oxide (ITO) or indium zinc oxide (IZO).

In addition, the polarizing plate PL1 or the polarizing plate PL2 may include a super-birefringent film. It is known that the super birefringent film depolarizes the transmitted light (natural light) when linearly polarized light enters. Even if the subject includes the polarized light, it can be photographed without discomfort. For example, when the electronic device 100 reflects the subject of the camera 1a, linearly polarized light is emitted from the electronic device 100, so there is a difference between the polarizing plate PL1 and the polarizing plate PL2, and the polarizing plate of the electronic device 100 as the object. The relationship between the angle and the brightness of the electronic device 100 incident on the subject of the camera 1a may cause discomfort during shooting. However, by providing the polarizing plate PL1 and the polarizing plate PL2 with a super-birefringent film, it is possible to suppress a change in brightness that causes an uncomfortable feeling.

As a film exhibiting super birefringence, for example, Cosmo Shine (registered trademark) of Toyobo Co., Ltd. is suitable for use. Here, the term “super birefringence” means that the retardation in the in-plane direction of light at 500 nm, for example, in the visible region is 800 nm or more.

The liquid crystal panel PNL has a first surface S1 on the side where an image is displayed, and a second surface S2 on the opposite side to the first surface S1. In this embodiment, the polarizing plate PL2 has a first surface S1, and the polarizing plate PL1 has a second surface S2.

The light sources EM2 and EM3 are located on the second surface S2 side of the liquid crystal panel PNL.

The display area DA, the incident light control area PCA, and the outgoing light control area ICA described later are areas overlapping with the first substrate SUB1, the second substrate SUB2, and the liquid crystal layer LC, respectively.

FIG. 3 is a top view showing the arrangement of the liquid crystal panel PNL and a plurality of cameras 1a, 1b shown in FIG. 2, and is a diagram showing the equivalent circuit of one pixel PX at the same time. In FIG. 3, the liquid crystal layer LC and the sealing material SE are shown with different diagonal lines.

As shown in FIG. 3, although the display area DA is substantially a quadrangular area, the four corners may have rounded corners, or a polygonal or circular shape other than the quadrangular shape. The display area DA is surrounded by the sealing material SE.

The liquid crystal panel PNL has a pair of short sides E11 and E12 extending in the direction X, and a pair of long sides E13 and E14 extending in the direction Y. The liquid crystal panel PNL includes a plurality of pixels PX arranged in a matrix in the direction X and the direction Y in the display area DA. Each pixel PX in the display area DA has the same circuit configuration. As shown in the enlarged display in FIG. 3, each pixel PX includes a switching element SW, a pixel electrode PE, a common electrode CE, a liquid crystal layer LC, and the like.

The switching element SW is composed of, for example, a thin film transistor (TFT). The switch element SW is electrically connected to a corresponding one of the plurality of scan lines G, a corresponding one of the plurality of signal lines S, and the pixel electrode PE. The scanning line G is given a control signal for controlling the switching element SW. The signal line S is given an image signal such as a video signal as a signal different from the control signal. A common voltage is applied to the common electrode CE. The liquid crystal layer LC is driven by a voltage (electric field) generated between the pixel electrode PE and the common electrode CE. The capacitor CP is formed, for example, between an electrode having the same potential as the common electrode CE and an electrode having the same potential as the pixel electrode PE.

The electronic device 100 further includes a wiring board 5 and an IC chip 6.

The wiring substrate 5 is mounted on the extended portion Ex of the first substrate SUB1, and is connected to the extended portion Ex. The IC chip 6 is mounted on the wiring substrate 5 and is electrically connected to the wiring substrate 5. In addition, the IC chip 6 can be mounted on the extended portion Ex and electrically connected to the extended portion Ex. The IC chip 6 includes, for example, a display driver that outputs signals necessary for image display, and the like. The wiring board 5 may be a flexible printed circuit board that can be bent.

In FIG. 3, the electronic device 100 includes eight cameras 1 in the display area DA. Among them, in the figure, the incident light control area PCA is formed overlapping with the camera 1a in the upper center. In addition, the incident light control area PCA includes an outer periphery in contact with the display area DA. The general pixel PX is superimposed on the other camera 1b, and the general display is performed on the pixel PX superimposed on the camera 1b.

Since the polarizing plate PL1 and the polarizing plate PL2 have high transmittance in the wavelength region of infrared light and transmit infrared light, even if the pixel PX overlaps the cameras 1a and 1b, the cameras 1a and 1b can receive infrared light. By performing normal display on the pixels PX overlapping with the camera 1b, the user can use the electronic device 100 without being aware of the position of the camera 1b. In addition, since the area of the display area DA is not reduced, the arrangement of a plurality of cameras 1b can be realized. Moreover, the user will not be aware that there are multiple cameras 1b. In particular, when the electronic device 100 is used in an automated teller machine (ATM) or the like, by arranging the camera 1b in a part fixed to the black display, it can further make it difficult for the user to recognize the existence of the camera 1b.

The symbol 300 is an indicator, which can intuitively notify the user of the state of the cameras 1a and 1b. For example, in the case of fingerprint authentication, etc., the indicator 300 can notify the user of the best position of the finger. In addition, the arrow 400 is a mark (mark) displayed when the user is notified of the position of the camera 1b. The displayed figure is not only the arrow 400, but also a suitable shape that encloses the periphery of the camera 1b into a circle.

FIG. 4 is a top view showing the arrangement of pixels PX in the liquid crystal panel PNL.

As shown in FIG. 4, each main pixel MPX is composed of a plurality of pixels PX. The plural main pixels MPX are classified into two types of main pixels MPXa and MPXb. The two main pixels MPXa and MPXb adjacent to the direction Y constitute the unit pixel UPX. The main pixels MPXa and MPXb respectively correspond to the smallest units for displaying color images. The main pixel MPXa includes a pixel PX1a, a pixel PX2a, and a pixel PX3a. The main pixel MPXb includes a pixel PX1b, a pixel PX2b, and a pixel PX3b. In addition, the shape of the aforementioned pixel PX is a substantially parallelogram as shown in the figure.

The main pixel MPXa and the main pixel MPXb include pixels PX of a plurality of colors arranged in the direction X, respectively. The pixel PX1a and the pixel PX1b are pixels of the first color, and have a coloring layer CF1 of the first color. The pixel PX2a and the pixel PX2b are pixels of a second color different from the first color, and have a coloring layer CF2 of the second color. The pixels PX3a and PX3b are pixels of a third color that are different from the first and second colors, and have a coloring layer CF3 of the third color.

The main pixel MPXa and the main pixel MPXb are repeatedly arranged in the direction X, respectively. The columns of the main pixels MPXa arranged in the direction X and the columns of the main pixels MPXb arranged in the direction X are alternately arranged in the direction Y. The pixels PX of each of the main pixels MPXa extend in the first extension direction d1, and the pixels PX of each of the main pixels MPXb extend in the second extension direction d2. In addition, the first extension direction d1 is a direction different from the direction X and the direction Y. The second extension direction d2 is a direction different from the direction X, the direction Y, and the first extension direction d1. In the example shown in FIG. 5, the first extending direction d1 is a right obliquely downward direction, and the second extending direction d2 is a left obliquely downward direction.

In the case where the shape of the pixel PX is a substantially parallelogram as shown in the figure, a plurality of areas where the rotation direction of the guide is different from each other can be set as the unit pixel UPX. That is, by combining the two main pixels MPXa and MPXb, it is also possible to form a large number of areas with respect to the pixels of each color, and it is possible to compensate for the viewing angle characteristics. Therefore, if attention is paid to the viewing angle characteristics, the combined unit pixel UPX of the main pixel MPXa and the main pixel MPXb corresponds to the smallest unit for displaying a color image.

FIG. 5 is a top view showing one unit pixel UPX of the liquid crystal panel PNL, and is a diagram showing the scanning line G, the signal line S, the pixel electrode PE, and the light shielding part BMA. In addition, in FIG. 5, only the necessary configuration is illustrated, and the illustration of the switching element SW, the common electrode CE, the color filter CF, and the like are omitted.

As shown in FIG. 5, the plurality of pixels PX have a structure corresponding to the FFS (Fringe Field Switching, boundary electric field switching wide viewing angle technology) mode, which is one of the display modes using the lateral electric field. The scanning lines G and the signal lines S are arranged on the above-mentioned first substrate SUB1, and on the other hand, the light shielding portion BMA (light-shielding layer BM) is arranged on the above-mentioned second substrate SUB2. The scan line G and the signal line S extend across the display area (DA) to cross each other. In addition, the light-shielding portion BMA is a grid-shaped light-shielding portion that is located in the display area DA and partitions the pixels PX, and is represented by a two-dot chain line in the figure.

The light shielding part BMA has at least the function of shielding the light irradiated from the above-mentioned lighting device (IL). The light-shielding part BMA is made of black resin and other materials with high light absorption rate. The light shielding part BMA is formed in a lattice shape. The light-shielding portion BMA is formed integrally by a plurality of light-shielding portions BMA1 extending in the direction X and a plurality of light-shielding portions BMA2 that are bent and extended along the first extension direction d1 and the second extension direction d2.

Each scan line G extends in the direction X. Each scanning line G is opposed to the corresponding light-shielding portion BMA1 and extends along the corresponding light-shielding portion BMA1. The light shielding portion BMA1 is opposed to the scanning line G, the end portion of the pixel electrode PE, and the like. Each signal line S is curved and extends along the direction Y, the first extension direction d1, and the second extension direction d2. Each signal line S is opposed to the corresponding light-shielding portion BMA2 and extends along the corresponding light-shielding portion BMA2.

The light shielding layer BM has a plurality of opening areas AP. The opening area AP is defined by the light-shielding part BMA1 and the light-shielding part BMA2. The opening area AP of the main pixel MPXa extends in the first extending direction d1. The opening area AP of the main pixel MPXb extends in the second extending direction d2.

The pixel electrode PE of the main pixel MPXa includes a plurality of linear pixel electrodes PA located in the opening area AP. The plurality of linear pixel electrodes PA extend linearly in the first extension direction d1, and are arranged at intervals in an orthogonal direction dc1 orthogonal to the first extension direction d1. The pixel electrode PE of the main pixel MPXb includes a plurality of linear pixel electrodes PB located in the opening area AP. The plurality of linear pixel electrodes PB extend linearly in the second extension direction d2, and are arranged at intervals in an orthogonal direction dc2 orthogonal to the second extension direction d2.

In the display area DA, the aforementioned alignment films AL1 and AL2 have an alignment axis AA parallel to the direction Y. The alignment direction AD1 of the alignment film AL1 is parallel to the direction Y, and the alignment direction AD2 of the alignment film AL2 is parallel to the alignment direction AD1.

When a voltage is applied to the above-mentioned liquid crystal layer (LC), the rotation state (alignment state) of the liquid crystal molecules in the opening area AP of the main pixel MPXa and the rotation state (alignment state) of the liquid crystal molecules in the opening area AP of the main pixel MPXb Status) are different from each other. Therefore, the viewing angle characteristic can be compensated.

As described above, in FIGS. 4 and 5, the configuration for compensating the viewing angle characteristic in one unit pixel UPX has been described. However, unlike the first embodiment, compensation can be performed with respect to viewing angle characteristics in one main pixel MPX. FIG. 6 is a top view of the main pixel MPX which is different from the first embodiment, and is a diagram showing the scanning line G, the signal line S, the pixel electrode PE, and the light shielding part BMA.

As shown in FIG. 6, each opening area AP extends in the second extension direction d2, curves in the middle, and extends in the first extension direction d1. Each opening area AP has the shape of the symbol of <, and has a first opening area AP1, and a second opening area AP2. The first opening area AP1 extends in the first extending direction d1, and the second opening area AP2 extends in the second extending direction d2.

The pixel electrode PE extends in the second extension direction d2, bends halfway, and extends in the first extension direction d1. The pixel electrode PE includes a plurality of linear pixel electrodes PA and a plurality of linear pixel electrodes PB. The plurality of linear pixel electrodes PA are located in the first opening area AP1, extend linearly in the first extension direction d1, and are arranged at intervals in the orthogonal direction dc1. The plurality of linear pixel electrodes PB are located in the second opening area AP2, extend linearly in the second extension direction d2, and are arranged at intervals in the orthogonal direction dc2. One continuous linear pixel electrode PA and one linear pixel electrode PB have a shape with a mark of <.

It is feasible that under the top view with the pixel PX1 on the left and the pixel PX3 on the right, one continuous linear pixel electrode PA and one linear pixel electrode PB have the shape of the sign of >, and the opening area AP has the shape of the sign of> .

When a voltage is applied to the above-mentioned liquid crystal layer (LC), the rotation state of the liquid crystal molecules in the first opening area AP1 and the rotation state of the liquid crystal molecules in the second opening area AP2 are different from each other. Each opening area AP has 4 areas in which the rotation direction of the guide is different from each other. Therefore, the liquid crystal panel PNL can obtain good viewing angle characteristics.

In addition, in this first embodiment, the pixel electrode PE functions as a display electrode, and the linear pixel electrode PA and the linear pixel electrode PB function as a linear display electrode.

FIG. 7 is a cross-sectional view of the liquid crystal panel PNL including the pixels PX1 and PX2 shown in FIG. 5. The liquid crystal panel PNL has a configuration corresponding to the FFS (Fringe Field Switching, boundary electric field switching wide viewing angle technology) mode, which is one of the display modes using the lateral electric field.

As shown in FIG. 7, the first substrate SUB1 is located between the insulating substrate 10 and the alignment film AL1, and includes an insulating layer 11, a signal line S, an insulating layer 12, a common electrode CE, a metal layer ML, an insulating layer 13, and a pixel electrode PE etc. In addition, a polarizing plate PL1 is formed on the outer side of the first substrate SUB1.

The insulating layer 11 is disposed on the insulating substrate 10. In addition, although not described in detail, between the insulating substrate 10 and the insulating layer 11, the above-mentioned scanning line (G), the gate electrode and semiconductor layer of the switching element SW, and other insulating layers are arranged. The signal line S is formed on the insulating layer 11. The insulating layer 12 is disposed on the insulating layer 11 and the signal line S.

The common electrode CE is provided on the insulating layer 12. The metal layer ML is disposed on the common electrode CE and connected to the common electrode CE. The metal layer ML is located directly above the signal line S. In addition, although in the example shown in the figure, the first substrate SUB1 is provided with the metal layer ML, the metal layer ML may be omitted. The insulating layer 13 is disposed on the common electrode CE and the metal layer ML.

The pixel electrode PE is formed on the insulating layer 13. Each pixel electrode PE is located between adjacent signal lines S, and faces the common electrode CE. In addition, each pixel electrode PE has a slot at a position opposed to the common electrode CE (open area AP). The common electrode CE and the pixel electrode PE are formed of transparent conductive materials such as ITO and IZO. The insulating layer 13 is sandwiched between the pixel electrode PE and the common electrode CE. The alignment film AL1 is disposed on the insulating layer 13 and the pixel electrode PE, and covers the pixel electrode PE and the like.

On the other hand, the second substrate SUB2 is provided on the side of the insulating substrate 20 opposite to the first substrate SUB1: a light-shielding layer BM including a light-shielding portion BMA2, a color filter CF including colored layers CF1, CF2, and CF3, and a transparent layer OC, and alignment film AL2, etc. The light shielding portion BMA2 is formed on the inner surface of the insulating substrate 20. The light shielding portion BMA2 is located directly above the signal line S and the metal layer ML. The colored layers CF1 and CF2 are respectively formed on the inner surface of the insulating substrate 20, and a part thereof overlaps the light shielding portion BMA2. The transparent layer OC covers the color filter CF. The alignment film AL2 covers the transparent layer OC. In addition, a polarizing plate PL2 is formed on the outer side of the second substrate SUB2.

In addition, the liquid crystal panel PNL can be configured in the display area DA without the light-shielding portion BMA2 and the light-shielding portion BMA1 (FIG. 6 ). In this case, in the display area DA, the metal layer ML is formed in a grid shape, so that the metal layer ML can have a light-shielding function, instead of the light-shielding parts BMA1 and BMA2.

The liquid crystal layer LC has a display liquid crystal layer LCI located in the display area DA. For example, when the transmission axis of the polarizing plate PL1 and the polarizing plate PL2 are orthogonal, in the pixel PX1, no voltage (electric field) is generated between the pixel electrode PE and the common electrode CE, and no voltage is applied to the display liquid crystal layer LCI. Next, the liquid crystal molecules contained in the display liquid crystal layer LCI are initially aligned between the alignment film AL1 and the alignment film AL2 in the direction of the transmission axis of the polarizing plate PL1. Therefore, since no phase difference occurs in the liquid crystal layer LC, the transmission axes of the polarizing plate PL1 and the polarizing plate PL2 are orthogonal, and the pixel PX1 has the minimum transmittance, and black is displayed. That is, in the pixel PX1, the liquid crystal panel PNL performs a light-shielding function.

On the other hand, in the pixel PX1a, when the voltage (electric field) generated between the pixel electrode PE and the common electrode CE is applied to the conduction state of the display liquid crystal layer LCI, the liquid crystal molecules are aligned in a direction different from the initial alignment direction. The alignment direction is controlled by the electric field. Therefore, a phase difference occurs in the liquid crystal layer LC, and in the pixel PX1, the liquid crystal panel PNL performs a light-transmitting function. Therefore, the pixel PX1 in the on state exhibits a color corresponding to the colored layer CF1.

Although the method of the liquid crystal panel PNL is the so-called normally black type that displays black in the off state, it can be the so-called normally white type that displays black in the on state (displays white in the off state).

Among the pixel electrode PE and the common electrode CE, the electrode closer to the display liquid crystal layer LCI (liquid crystal layer LC) is the pixel electrode PE, and the pixel electrode PE functions as a display electrode as described above. However, the pixel electrode PE and the common electrode CE, which is closer to the display liquid crystal layer LCI (liquid crystal layer LC), may be the common electrode CE. In this case, the common electrode CE has a slot located in the opening area AP, functions as a display electrode as described above, and has a linear display electrode instead of the pixel electrode PE.

The liquid crystal panel PNL can be configured without the fourth light-shielding area LSA4, the fifth light-shielding area LSA5, the fourth light-shielding portion BM4, and the fifth light-shielding portion BM5 in the incident light control area PCA. This is because even if the fourth light-shielding portion BM4 and the fifth light-shielding portion BM5 are not provided, the influence on the amount of received light caused by the winding wiring L described later is slight, which is a level that can be corrected.

In addition, the liquid crystal panel PNL may be configured without the third light-shielding area LSA3, the third light-shielding portion BM3, and the third incident light control area TA3.

The plurality of first control electrodes RL1 and the plurality of second control electrodes RL2 are alternately arranged in the orthogonal direction dc1.

The third control electrode structure RE3 and the fourth control electrode structure RE4 are located in the second light shielding area LSA2 and the second incident light control area TA2. The third control electrode structure RE3 and the fourth control electrode structure RE4 are respectively represented in the shape of a semicircle having a side parallel to the first extending direction d1. The side of the third control electrode structure RE3 and the side of the fourth control electrode structure RE4 are located in the orthogonal direction dc1 with an interval therebetween. In addition, although the 3rd control electrode structure RE3 and the 4th control electrode structure RE4 show approximate shapes by the shape of a semicircle, the detailed structure is mentioned later.

The fifth control electrode structure RE5 has a fifth power supply line CL5 and a fifth control electrode RL5. The fifth feeder wiring CL5 includes a fifth wiring WL5. The fifth feeder line CL5 is located in the third light-shielding area LSA3, and has a C-shape.

The plurality of fifth control electrodes RL5 have: a fifth control electrode RL5 connected to the fifth wiring WL5 at both ends, and a fifth control electrode RL5 connected to the fifth wiring WL5 at one end and not connected to the fifth wiring WL5 at the other end Control electrode RL5.

The sixth control electrode structure RE6 has a sixth power supply wiring CL6 and a sixth control electrode RL6. The sixth feeder wiring CL6 includes a sixth wiring WL6. The sixth control electrode structure RE6 has the same structure as the fifth control electrode structure RE5. Although the sixth wiring WL6 is located on the inner side of the fifth wiring WL5, it may be located on the outer side of the fifth wiring WL5.

The plurality of fifth control electrodes RL5 and the plurality of sixth control electrodes RL6 are alternately arranged in the orthogonal direction dc1.

The first to sixth routing wires L1 to L6 are formed of metal. For example, the first to sixth routing wires L1 to L6 are located in the same layer as the above-mentioned metal layer ML, and are formed of the same metal as the above-mentioned metal layer ML.

The first to sixth routing wires L1 to L6 are bundled and extend in the area covered by one light shielding portion (BMA2) in the display area DA. However, the first to sixth routing wires L1 to L6 may not be bundled, and each of the first to sixth routing wires L1 to L6 only needs to extend in at least one of the light-shielding portion BMA1 and the light-shielding portion BMA2 in the display area DA That's it.

In addition, the first feeder wiring CL1, the second feeder wiring CL2, the fifth feeder wiring CL5, the sixth feeder wiring CL6, and the first to sixth routing wirings L1 to L6 can be made of transparent conductive layers and metal layers The laminated body composition.

As explained using FIG. 7, the pixel electrode PE and the common electrode CE in the display area DA are formed of a transparent conductive material (transparent conductive film), and the pixel PX has two different transparent conductive films. As described later, the first wiring WL1 to the sixth wiring WL6 are formed of one transparent conductive film of two transparent conductive films, and the first control electrode RL1 to the sixth control electrode RL6 are formed of another transparent conductive film. 1 The control electrode RL1 to the sixth control electrode RL6 are formed in the same layer.

The liquid crystal panel PNL has a configuration corresponding to the IPS mode, which is one of the display modes using the lateral electric field, in the incident light control area PCA. The above-mentioned first control electrode RL1 to sixth control electrode RL6 respectively have a shape different from the shape of the pixel electrode PE corresponding to the aforementioned FFS mode.

As represented by the first control electrode RL1 and the second control electrode RL2, a voltage is supplied to the alternately arranged control electrodes, and the liquid crystal molecules are driven by the potential difference generated between the electrodes. For example, the wiring can be extended from the display area DA, the first control electrode RL1 can be supplied with the same image signal as the pixel electrode, and the second control electrode RL2 can be supplied with the same normal voltage as the common electrode. In addition, it is also possible to supply a signal of positive polarity with respect to the normal voltage to the first control electrode RL1, and supply a signal of negative polarity to the second control electrode RL2.

In the incident light control area PCA, the aforementioned alignment films AL1 and AL2 have an alignment axis AA parallel to the direction Y. That is, the alignment axes AA of the alignment films AL1 and AL2 are parallel to the incident light control area PCA in the display area DA. In the incident light control area PCA, the alignment direction AD1 of the alignment film AL1 is parallel to the direction Y, and the alignment direction AD2 of the alignment film AL2 is parallel to the alignment direction AD1.

When no voltage is applied to the liquid crystal layer LC, the initial alignment direction of the liquid crystal molecules in the display area DA is the same as the initial alignment direction of the liquid crystal molecules in the incident light control area PCA. The linear pixel electrode (linear display electrode) PA described above extends in parallel with the control electrode RL. In the X-Y plane, the first extension direction d1 and the second extension direction d2 are respectively inclined by 10′ with respect to the direction Y. Therefore, the rotation direction of the liquid crystal molecules can be aligned in the display area DA and the incident light control area PCA. In addition, the inclination of the linear pixel electrode PA has been described. However, the above is the same when replacing the inclination of the linear pixel electrode PA with the inclination of the slot of the common electrode.

FIG. 10 is a cross-sectional view showing the incident light control area PCA of the liquid crystal panel PNL. In FIG. 10, the illustration of the signal line S, the scanning line G, etc. is omitted.

As shown in FIG. 10, one of the two conductors formed through the insulating layer 13 is provided on the same layer as one of the pixel electrode PE and the common electrode CE, and is formed of the same material as the above one electrode. The other conductor of the above two conductors is provided on the same layer as the other electrode of the pixel electrode PE and the common electrode CE, and is formed of the same material as the other electrode.

In FIG. 10, the second wiring WL2, the second control electrode RL2, the fourth control electrode structure RE4, the sixth wiring WL6, and the sixth control electrode RL6 are provided on the insulating layer 12 and covered by the insulating layer 13. The second wiring WL2, the second control electrode RL2, the fourth control electrode structure RE4, the sixth wiring WL6, and the sixth control electrode RL6 are arranged on the same layer as the common electrode CE, and are made of the same transparent conductive material as the common electrode CE Material formation.

The first wiring WL1, the first control electrode RL1, the third control electrode structure RE3, the fifth wiring WL5, and the fifth control electrode RL5 are provided on the insulating layer 13 and covered by the alignment film AL1. The first control electrode RL1, the third control electrode structure RE3, the fifth wiring WL5, and the fifth control electrode RL5 are provided on the same layer as the pixel electrode PE, and are formed of the same transparent conductive material as the pixel electrode PE.

For example, the insulating layer 13 is sandwiched between the first control electrode RL1 (first control electrode structure RE1) and the second control electrode RL2 (second control electrode structure RE2). In addition, the first control electrode RL1, the second control electrode RL2, the third control electrode structure RE3, the fourth control electrode structure RE4, the fifth control electrode RL5, and the sixth control electrode RL6 may be formed in the same layer.

In the incident light control area PCA, the alignment film AL1 covers the first wiring WL1, the first control electrode RL1, the second wiring WL2, the second control electrode RL2, the third control electrode structure RE3, the fourth control electrode structure RE4, and the fifth control electrode structure. The wiring WL5, the fifth control electrode RL5, the sixth wiring WL6, and the sixth control electrode RL6 are in contact with the liquid crystal layer LC.

Here, the pitch in the orthogonal direction dc1 of the first control electrode RL1 and the second control electrode RL2 is set to the pitch pi1, and the pitch in the orthogonal direction dc1 of the fifth control electrode RL5 and the sixth control electrode RL6 is set to Is the pitch pi2. In other words, the pitch pi1 is the pitch in the orthogonal direction dc1 between the center of the first control electrode RL1 and the center of the second control electrode RL2. The pitch pi2 is the pitch in the orthogonal direction dc1 between the center of the fifth control electrode RL5 and the center of the sixth control electrode RL6.

The pitch pi1 and the pitch pi2 may be fixed respectively, but it is preferable to set them randomly. Thereby, it is possible to prevent interference of light generated when the pitches pi1 and pi2 are set to be constant.

In the second substrate SUB2, the color filter CF is not provided in the incident light control area PCA.

The liquid crystal layer LC has: a first control liquid crystal layer LC1 located in the first incident light control area TA1, a second control liquid crystal layer LC2 located in the second incident light control area TA2, and a third control located in the third incident light control area TA3 Liquid crystal layer LC3.

To the first control liquid crystal layer LC1, a voltage generated by the first control electrode RL1 and the second control electrode RL2 is applied. To the second control liquid crystal layer LC2, a voltage generated by the third control electrode structure RE3 and the fourth control electrode structure RE4 is applied. To the third control liquid crystal layer LC3, a voltage generated by the fifth control electrode RL5 and the sixth control electrode RL6 is applied.

The first control voltage is applied to the first control electrode structure RE1 via the first routing wire L1, the second control voltage is applied to the second control electrode structure RE2 via the second routing wire L2, and the third control electrode structure RE3 is via the third The third control voltage is applied to the routing wiring L3, the fourth control voltage is applied to the fourth control electrode structure RE4 via the fourth routing wiring L4, and the fifth control voltage is applied to the fifth control electrode structure RE5 via the fifth routing wiring L5. A sixth control voltage is applied to the sixth control electrode structure RE6 via the sixth lead wire L6.

The voltage levels of the first control voltage, the third control voltage, and the fifth control voltage can be the same as the image signal and the common voltage. The voltage levels of the second control voltage, the fourth control voltage, and the sixth control voltage The standard may be the same as the other of the image signal and the common voltage.

Or, the first control voltage, the third control voltage, and the fifth control voltage may have the voltage level of the first polarity with respect to the common voltage, and the second control voltage, the fourth control voltage, and the sixth control voltage may have the common voltage The voltage level of the second polarity. In addition, among the first polarity and the second polarity, one has a positive polarity and the other has a negative polarity.

When the incident light control area PCA is described as the diaphragm DP, the state of the opening of the diaphragm DP is defined. FIG. 11 is a plan view showing the incident light control area PCA when the liquid crystal panel PNL is driven under the first condition. FIG. 12 is a plan view showing the incident light control area PCA when the liquid crystal panel PNL is driven under the second condition. FIG. 13 is a plan view showing the incident light control area PCA when the liquid crystal panel PNL is driven under the third condition. FIG. 14 is a plan view showing the incident light control area PCA when the liquid crystal panel PNL is driven under the fourth condition. In addition, in FIGS. 11 to 14, illustration of the fourth light shielding portion BM4 and the fifth light shielding portion BM5 is omitted. In the figure, a grid pattern is provided to the incident light control area TA in a non-transmitting state.

As shown in FIG. 11, the liquid crystal display device DSP is driven under the first condition to set the aperture DP to the maximum open state (open state).

As shown in FIG. 12, the liquid crystal display device DSP is driven under the second condition to set the aperture DP to a state where it is narrowed to a minimum.

As shown in FIG. 13, the liquid crystal display device DSP is driven under the third condition to set the aperture DP to a state between a state where it is opened to the maximum and a state where it is narrowed to the minimum.

As shown in FIG. 14, the liquid crystal display device DSP is driven under the fourth condition to set the aperture DP to a closed state.

As described above, the incident light control area PCA includes a first incident light control area TA1, a third incident light control area TA3, and a second incident light control area TA2 from the outside toward the center, and corresponds to the first to fourth conditions The transmission state and non-transmission state of the first incident light control area TA1, the third incident light control area TA3, and the second incident light control area TA2 are as follows.

For example, when the first control liquid crystal layer LC1, the second control liquid crystal layer LC2, and the third control liquid crystal layer LC3 are driven under the first condition, the liquid crystal panel PNL divides the first incident light control area TA1 and the second incident light control area TA2. , And the third incident light control area TA3 is set to a transmission state.

When the first control liquid crystal layer LC1, the second control liquid crystal layer LC2, and the third control liquid crystal layer LC3 are driven under the second condition, the liquid crystal panel PNL sets the second incident light control area TA2 to a transmission state and sets the first incident light The control area TA1 and the third incident light control area TA3 are set in a non-transmitting state.

When the first control liquid crystal layer LC1, the second control liquid crystal layer LC2, and the third control liquid crystal layer LC3 are driven under the third condition, the liquid crystal panel PNL sets the third incident light control area TA3 and the second incident light control area TA2 to In the transmission state, the first incident light control area TA1 is set to the non-transmission state.

When the first control liquid crystal layer LC1, the second control liquid crystal layer LC2, and the third control liquid crystal layer LC3 are driven under the fourth condition, the liquid crystal panel PNL divides the first incident light control area TA1, the third incident light control area TA3, and The second incident light control area TA2 is set in a non-transmitting state. Here, the non-transmissive state means a state in which visible light is shielded, or a state in which the transmittance is lower than the above-mentioned transmitted state.

Furthermore, in addition to the aforementioned first to fourth conditions, the following fifth to seventh conditions can be used for driving. 15 is a plan view showing the incident light control area PCA when the liquid crystal panel PNL is driven under the fifth condition. FIG. 16 is a plan view showing the incident light control area PCA when the liquid crystal panel PNL is driven under the sixth condition. FIG. 17 is a plan view showing the incident light control area PCA when the liquid crystal panel PNL is driven under the seventh condition.

As shown in FIG. 15, under the fifth condition, the second incident light control area TA2 is set to a transmission state to form an opening that narrows the aperture DP to the minimum, and by reducing the first incident light control area TA1 It is set to a transmission state, and the third incident light control area TA3 is set to a non-transmission state, so that the diaphragm DP forms a ring-shaped opening RO1. The light sources EM2 and EM3 are arranged on the side of the camera 1a so as to face the ring-shaped opening RO1. For example, in the circumferential direction of the opening RO1, the light source EM2 and the light source EM3 are alternately arranged.

The liquid crystal panel PNL has an emission light control area ICA. In this embodiment, the emitted light control area ICA is included in the first incident light control area TA1. The light source EM3 overlaps with the emitted light control area ICA (the first incident light control area TA1). In addition, although the light source EM2 also overlaps with the emitted light control area ICA, it is not limited to this, and the light source EM2 may overlap with the first light shielding portion BM1 and the like.

As shown in FIG. 16, under the sixth condition, the second incident light control area TA2 and the third incident light control area TA3 are set to a non-transmissive state, and the first incident light control area TA1 is set to a transmissive state, and The aperture DP alone forms a ring-shaped opening RO1.

As shown in FIG. 17, under the seventh condition, the second incident light control area TA2 and the first incident light control area TA1 are set to a non-transmissive state, and the third incident light control area TA3 is set to a transmissive state, and The aperture DP separately forms a ring-shaped opening RO2 inside the third light shielding portion BM3.

According to the above content, the incident light control area PCA of the liquid crystal panel PNL constitutes the aperture of the camera 1a. Therefore, it is possible to open the iris (the first condition), or narrow the iris (the third condition), or further narrow the iris (the second condition), or close the iris (the fourth condition), and it is possible to change the focal depth and to The camera 1a takes pictures. The LCD panel PNL can open or narrow the aperture concentrically. In other words, the liquid crystal panel PNL can control the light transmission area concentrically in the incident light control area PCA.

Furthermore, under the fifth condition, the first incident light control area TA1 is set in a transmission state, and the subject is illuminated by visible light from the light source EM3 provided on the side of the camera 1a, and the second incident light control area TA2 is set In the transmission state, visible light from the smallest opening can be incident on the camera 1a.

Also, under the sixth condition, an image formed by visible light passing through the first incident light control area TA1 can be obtained, and under the seventh condition, an image formed by visible light passing through the third incident light control area TA3 can be obtained. By performing imaging under the sixth and seventh conditions, it is possible to obtain an image formed by light passing through a plurality of ring-shaped openings RO arranged in concentric circles. Through the use of concentric circular openings for imaging under the first to third conditions, and the fifth to seventh conditions, a signal for adjusting the depth of focus can be obtained.

Since the polarizing plates PL1 and PL2 have high transmittance to infrared light, when the camera 1a receives infrared light, the visible light can also be set to a light-shielding state under the fourth condition, and one side can be installed on the side of the camera 1a. The light source EM2 irradiates infrared light, and the camera 1a receives the infrared light. In the camera 1b, infrared light can be irradiated from the light source EM2 provided on the side of the camera 1b, and the infrared light can be received by the camera 1b.

The aperture under the second condition can function as a pinhole for adjusting the amount of light incident on the camera 1a. In the case where the distance between the camera 1a and the subject is several cm, the resolution of the camera 1a is improved, and it is possible to take vivid photos at the closest distance to the subject. As an example of photographing in which the subject is close to the camera 1a, fingerprints can be photographed for fingerprint authentication. In addition, in situations where the amount of light is large, photography using pinholes is also effective.

In addition, when the aperture under the second condition functions as a pinhole and close-up photography is performed, when there is a problem that the amount of light from the subject is reduced, the first incident light can be controlled under the fifth condition The area TA1 is set in a transmission state, and the subject is illuminated with visible light from the light source EM3 provided on the side of the camera 1a.

In addition, the shape of the light shielding layer BM of the incident light control area PCA of the liquid crystal panel PNL can be variously changed. FIG. 18 is a plan view showing a modification example of the light shielding layer BM in the incident light control area PCA of the liquid crystal panel PNL.

As shown in FIG. 18, for example, the light-shielding layer BM further has a fourth light-shielding portion BM4 located in the incident light control area PCA and having a circular ring shape. The fourth light-shielding portion BM4 is located outside the second light-shielding portion BM2 and located inside the third light-shielding portion BM3.

The incident light control area PCA further has a fourth incident light control area TA4. The fourth incident light control area TA4 has an outer circumference in contact with the fourth light shielding portion BM4 and an inner circumference in contact with the second light shielding portion BM2, and has the shape of a ring. The second incident light control area TA2, the fourth incident light control area TA4, the third incident light control area TA3, and the first incident light control area TA1 have the same area and are located in concentric circles.

In the radial direction of the incident light control area PCA, the width of the fourth incident light control area TA4, the width of the third incident light control area TA3, and the width of the first incident light control area TA1 are different from each other. The ring-shaped incident light control area TA has a smaller width as it is located on the outer peripheral side. By setting all of the first to fourth incident light control areas TA1 to TA4 to a state that allows visible light to pass through, the fourth incident light control area TA4, the third incident light control area TA3, and the first incident light control area can be controlled. Each area TA1 is regarded as a transparent ring. This allows the liquid crystal panel PNL to function as a Fresnel zone plate in the incident light control area PCA.

In addition, in the example shown in FIG. 18, the number of annular incident light control regions TA is three. However, the incident light control area PCA may have more than 4 annular incident light control areas TA.

According to the liquid crystal display device DSP and the electronic device 100 of the first embodiment configured as described above, it is possible to obtain the liquid crystal display device DSP and the electronic device 100 that can perform good photographing and can control the light transmission area of the incident light control area PCA.

The liquid crystal panel PNL is configured to selectively transmit visible light emitted from the light source EM3 in the emitted light control area ICA. The liquid crystal panel PNL is configured to selectively transmit visible light from the outside so that the visible light from the outside is incident on the camera 1a in the incident light control area PCA.

By combining the camera 1a and the liquid crystal panel PNL, ultra close-up photography can be performed, for example, fingerprints can be taken. Ultra close-up photography is based on the principle of a pinhole camera, which can be used for fingerprint authentication without focusing, allowing the finger to approach the protective glass CG. Since visible light can be emitted from the light source EM3, fingerprints can also be taken with the finger in contact with the protective glass CG.

The camera 1a can receive infrared light and photograph the front of the screen of the liquid crystal display device DSP.

The electronic machine 100 can perform visible light detection and infrared light detection in different periods. The liquid crystal panel PNL is configured to transmit visible light from the outside in the incident light control area PCA during the first detection period in which the visible light is not emitted from the light source EM2. The liquid crystal panel PNL is configured to allow visible light to be emitted from the emission light control area ICA to the outside during the first detection period. Therefore, in the first detection period, it is possible to prevent infrared light from becoming noise, and to use visible light to perform photography.

The liquid crystal panel PNL is configured to cause infrared light to enter the cameras 1a and 1b during the second detection period in which infrared light is emitted from the light source EM2 and the infrared light is detected in a period different from the first detection period. The liquid crystal panel PNL is configured to stop the emission of visible light from the emission light control area ICA to the outside during the second detection period, and prevent visible light from the outside in the incident light control area PCA. Therefore, in the second detection period, it is possible to prevent visible light from becoming noise, and to use infrared light to perform photography.

(Second Embodiment) Next, the second embodiment will be described. The electronic device 100 has the same configuration as the above-mentioned first embodiment except for the configuration described in the second embodiment. Describes the aperture of the aperture. 19 is a diagram showing a part of the liquid crystal panel PNL of the electronic device 100 of the second embodiment and the camera 1a, and simultaneously shows a plan view showing the liquid crystal panel PNL and the camera 1a, and a cross-sectional view showing the liquid crystal panel PNL and the camera 1a picture. In the figure, the outer shape of the camera 1a is shown. The light shielding layer BM displays only the first light shielding portion BM1 in the incident light control area PCA.

As shown in FIG. 19, the liquid crystal panel PNL constitutes an aperture DP that switches the light transmission area concentrically in the incident light control area PCA. The aperture DP is located in front of the camera 1a, and light (visible light) passing through the aperture DP is incident on the camera 1a. By using the function of controlling the amount of transmitted light of the liquid crystal panel PNL, the aperture DP can control the amount of light incident to the camera 1a. As described later, the outer diameter of the diaphragm DP is determined by the diameter DI2 of the effective opening EA of the optical system 2 (camera 1a), and the inner diameter DI1 of the first shading part BM1 is larger than the diameter of the effective opening EA of the optical system 2 (camera 1a) DI2.

On the outer side of the outer periphery of the diaphragm DP, a first light shielding portion BM is formed in order to shield unnecessary light. Hereinafter, since the boundary is clear, the inner circumference I1 of the first light shielding portion BM1 is used to describe the outer circumference of the aperture DP. The diaphragm DP can increase or decrease the amount of light incident on the camera 1a by shielding the inner side of the first light shielding portion BM1 from the inner circumference I1. The first light-shielding portion BM1 having a width WI1 surrounds the effective opening EA and covers the unused first light-shielding area LSA1 around the camera 1a.

Regarding the light sources EM2 and EM3 shown in FIG. 19, by selecting the light source EM3 for irradiating visible light and the light source EM2 for irradiating infrared light, it is possible to mix the light source EM3 for irradiating visible light and the light source EM2 for irradiating infrared light, for example, alternately. Configuration. Moreover, in the case of fingerprint authentication, etc., it is not necessary to use the light of the entire visible light, and a light source that irradiates light of a specific wavelength in the wavelength region of the visible light can also be used.

20 is a cross-sectional view showing a part of a liquid crystal panel, a part of an illuminating device, and a camera of the second embodiment.

The liquid crystal panel PNL includes a first substrate SUB1, a second substrate SUB2, a liquid crystal layer LC, a polarizing plate PL1, a polarizing plate PL2, and the like. In the figure, the line between the first substrate SUB1 and the second substrate SUB2 represents the liquid crystal layer LC.

The illuminating device IL has a light guide body LG1 that emits the light from the light source EM1 as plane light, a light reflection sheet RS that reflects light from the light guide body LG1 to the liquid crystal panel PNL side, and a control light guide body LG1 The direction of the light of the optical sheet, etc. The above-mentioned optical sheet includes, for example, a light-diffusing sheet SS and a scallop sheet PS. The 稜鏡 sheet PS may include the 稜鏡 sheet PS1 and the 稜鏡 sheet PS2 shown in FIG. 2.

An opening ILO for disposing the camera 1a is formed in the lighting device IL, and a light-shielding wall CS2 is disposed between the light guide body LG1 and the like and the opening ILO. On the light-shielding wall CS2, a tape TP1 for fixing the 稜鏡 sheet PS is attached. The tape TP1 also has the function of shielding unnecessary light near the light-shielding wall CS2. In addition, the lighting device IL has a resin frame FR that is located at the periphery of the lighting device IL and houses the light guide LG1 and the like.

The camera 1a is arranged near the end of the liquid crystal panel PNL.

Next, the angle of the light incident on the effective opening EA of the camera 1 will be described. Here, as shown in FIG. 20, it is defined and explained on a virtual plane including the central axis AX1 of the optical system 2 (camera 1a) and the orthogonal axis AX2 orthogonal to the central axis AX1.

The point on the outermost periphery of the effective opening EA of the optical system 2 is set as the first point P1. Let the straight line passing through the first point P1 be the first reference line RF1. Set another point on the outermost circumference of the effective opening EA as the third point P3. Let the straight line passing through the third point P3 be the second reference line RF2. A straight line passing through the first point P1, the central axis AX1, and the third point P3 is referred to as the third reference line RF3. The point where the first reference line RF1 and the second reference line R intersect is defined as a fifth point P5. The point where the central axis AX1 and the third reference line RF3 intersect is referred to as the sixth point P6.

The sixth point P6 is also the center of the effective opening EA. The center axis AX1 is orthogonal to the third reference line RF3. In addition, the central axis AX1 is a perpendicular line to the surface forming the effective opening EA, and is generally the optical axis of the camera 1a (optical system 2). The first reference line RF1 and the second reference line RF2 may also be the optical paths of the outermost light rays of the light beam used for imaging determined by the focal length of the camera 1 or the size of the aforementioned imaging surface 3a.

The effective opening EA is circularly symmetrical with respect to the central axis AX1. The central axis AX1 passes through the fifth point P5. The first reference line RF1 and the central axis AX1 intersect at an angle θ. The second reference line RF2 and the central axis AX1 also cross at an angle θ. In addition, according to the camera 1a, the angle 2θ, which is twice the angle θ, is the viewing angle.

The light shielding wall CS2 is adjacent to the camera 1a in a direction parallel to the third reference line RF3. The light shielding wall CS2 is located between the camera 1a and the light guide LG1, and has a cylindrical shape.

Next, the third distance DT3 and the inner diameter DI1 will be described. Here, the third distance DT3 is the linear distance from the fifth point P5 to the central axis AX1 of the opening of the light shielding layer BM (the second opening OP2). FIG. 21 is another cross-sectional view showing a part of the liquid crystal panel PNL, a part of the lighting device IL, and the camera 1a of the second embodiment. Here, it is also defined and explained on a virtual plane including the central axis AX1 and the orthogonal axis AX2.

As shown in FIG. 21, the point on the inner circumference I1 of the first light shielding portion BM1 that is close to the first point P1 is referred to as the second point P2. Let the point on the inner circumference I1 of the first light shielding portion BM1 close to the third point P3 be the fourth point P4. The first reference line RF1 is a straight line passing through the first point P1 and the second point P2. The second reference line RF2 is a straight line passing through the third point P3 and the fourth point P4.

Among the light directed toward the camera 1 from the second point P2 (right side in the figure), the light that crosses at an angle less than the angle θ with respect to the central axis AX1 is not incident on the effective opening EA because it passes through the outside of the effective opening EA . In addition, among the light toward the camera 1 from the fourth point P4 (left side in the figure), the light that crosses at an angle less than the angle θ with respect to the central axis AX1 does not enter the effective opening EA. Even if the first incident light control area (TA1) is located on the right side of the second point P2 and on the left side of the fourth point P4, the influence on the amount of light incident to the effective opening EA is small.

Therefore, the circle formed by the line that crosses the center axis AX1 at an angle θ represented by the first reference line RF1 and passes through the outermost circumference of the effective opening EA and the point where the liquid crystal layer LC intersects becomes the effective maximum inner diameter of the aperture DP. path.

In addition, the liquid crystal layer LC alone has no light shielding function. In order to shield light, the functions of the liquid crystal layer LC, the polarizing plate PL1, the polarizing plate PL2, etc. must be combined. Strictly speaking, the liquid crystal layer LC is not considered to be the aperture DP, but to The liquid crystal layer LC forms the aperture DP, and further, since the boundary is clear, the description will be made assuming that the inside of the opening of the first light shielding portion BM1 represents the aperture DP in the plane where the first light shielding portion BM1 is formed.

In addition, as shown in FIG. 7, between the liquid crystal layer LC and the light shielding layer BM, there are the color filter CF, the transparent layer OC, and the alignment film AL2, but the total thickness of the layers is several μm, so The case where the liquid crystal layer LC and the light shielding layer BM are located on the same plane will be described. The first light shielding portion BM1 having a width WI1 shields unnecessary light near the outer periphery of the incident light control area PCA. Therefore, the inner circumference I1 can also be considered as the outermost circumference of the aperture DP.

Furthermore, the optical path of the outermost light can also be considered as being on the first reference line RF1 and on the second reference line RF2. That is, the optical path of the outermost light is a line connecting the outermost circumference of the structure functioning as the aperture DP and the outermost circumference of the effective opening EA of the camera 1.

The point on the central axis AX1 located at the opening of the light shielding layer BM (the second opening OP2) is referred to as the seventh point P7. If we pay attention to the triangle formed by the 5th point P5, the 2nd point P2, and the 7th point P7, and the triangle formed by the 5th point P5, the 4th point P4, and the 7th point P7 respectively, the following relationship holds . DI1/2=DT3×tanθ

As the third distance DT3 from the fifth point P5 to the seventh point P7 becomes longer, the inner diameter DI1 of the first light shielding portion BM1 also becomes longer. Therefore, when the inner diameter DI1 is to be reduced, the camera 1 must be close to the liquid crystal panel PNL.

The light from the lighting device IL is not irradiated from the inside of the area enclosed by the light-shielding wall CS2 toward the liquid crystal panel PNL. Therefore, in the first light-shielding area LSA1 (the range represented by the width WI1 from the second point P2 to the end EN1 of the tape TP1 on the light-irradiated area side, and the fourth point P4 to the end of the tape TP1 on the light-irradiated area side The width WI1 of EN2 indicates the range), and the first light shielding portion BM1 is arranged. This is because the first light-shielding area LSA1 becomes an area that is unfavorable for both the aperture DP and the display.

In order to form the display area DA as wide as possible, it is necessary to make the first light shielding portion BM1 as small as possible. By bringing the camera 1 close to the liquid crystal panel PNL, the inner diameter DI1 can be reduced, and the area surrounded by the first light shielding portion BM1 can be reduced.

Next, the relationship between the inner diameter DI1 of the first light shielding portion BM1 and the diameter DI2 of the effective opening EA of the camera 1a will be described. Fig. 22 is a cross-sectional view showing a part of the liquid crystal panel PNL and the camera 1a of the second embodiment. In addition, in order to simplify the drawing, in the liquid crystal panel PNL, the first light-shielding portion BM1 is represented by a solid line, and the liquid crystal layer LC in the opening of the first light-shielding portion BM1 is represented by a broken line. Here, it is also defined and explained on a virtual plane including the central axis AX1 and the orthogonal axis AX2.

As shown in FIG. 22, the linear distance on the central axis AX1 from the fifth point P5 to the sixth point P6 is set to the first distance DT1. The linear distance on the central axis AX1 of the sixth point P6 to the seventh point P7 (the opening of the light-shielding layer BM) is set as the second distance DT2. The inner diameter DI1 and the diameter DI2 can be respectively obtained by the following relational expressions. DI1/2=DT3×tanθ DI2/2=DT1×tanθ

According to the above relationship, the following relationship is established. DI1/DI2=DT3/DT1

For example, in the case where the inner diameter DI1 is to be less than twice the diameter DI2, the second distance DT2 (DT3-DT1) must be shorter than the first distance DT1.

In addition, in FIG. 22, the case where the aperture DP is opened (the first condition) is described. Therefore, in the incident light control area PCA, all of the first incident light control area TA1, the second incident light control area TA2, and the third incident light control area TA3 are set in a transmission state (FIGS. 8 and 11 ).

Next, the case where the aperture DP is narrowed (the third condition) will be described. Therefore, in the incident light control area PCA, the second incident light control area TA2 and the third incident light control area TA3 are set to a transmissive state, and the first incident light control area TA1 is set to a non-transmitting state (FIGS. 8 and 13 ).

FIG. 23 is another cross-sectional view showing a part of the liquid crystal panel PNL of the second embodiment and the camera 1a. The opening under the third condition is explained. In order to simplify the drawing, in the liquid crystal panel PNL, the first light shielding portion BM1 and the third light shielding portion BM3 are shown by solid lines, and the liquid crystal layer LC other than the first light shielding portion BM1 and the third light shielding portion BM3 is shown by dotted lines. Here, it is also defined and explained on a virtual plane including the central axis AX1 and the orthogonal axis AX2.

As shown in FIG. 23, when the aperture of the diaphragm DP is reduced and the light incident to the camera 1a is narrowed, the oblique incident light that crosses at a larger angle with respect to the central axis AX1 is opposed to the light at a smaller angle. The incident light crossing the central axis AX1 decreases. Therefore, there is a problem that the amount of light in the peripheral portion of the camera 1a is reduced.

Therefore, the inner diameter DI3 of the third light shielding portion BM3 for preventing the oblique incident light from being extremely reduced will be discussed. Here, a straight line parallel to the second reference line RF2 and passing through the first point P1 is referred to as the fourth reference line RF4. A straight line parallel to the first reference line RF1 and passing through the third point P3 is defined as the fifth reference line RF5. The point where the fourth reference line RF4 and the light shielding layer BM intersect is defined as an eighth point P8. The point where the fifth reference line RF5 and the light shielding layer BM intersect is defined as the ninth point P9.

Focusing on the fourth reference line RF4, within the light (oblique ray OL1) that crosses at an angle θ with respect to the central axis AX1, the light outside the fourth reference line RF4 for the effective opening EA does not enter the effective opening EA. Therefore, even if the light is shielded outside the eighth point P8 (right side in the figure), there is no increase or decrease in the oblique light OL1. Therefore, the inner circumference I3 of the third light shielding portion BM3 is located at the eighth point P8.

Similarly, when focusing on the fifth reference line RF5, within the light (oblique ray OL2) that crosses at an angle θ with respect to the central axis AX1, the light outside the fifth reference line RF5 for the effective opening EA does not enter the effective opening EA . Therefore, even if the light is shielded outside the 9th point P9 (right side in the figure), there is no increase or decrease in the oblique light OL2. Therefore, the inner circumference I3 of the third light shielding portion BM3 is located at the ninth point P9 on the other hand. However, if the light is shielded outside the ninth point P9, the light outside the ninth point P9 in the oblique ray OL1 is shielded.

The inner diameter DI3 of the third light-shielding portion BM3 is the same as the distance between the eighth point P8 and the ninth point P9, so that the amount of light at the periphery of the camera 1a does not decrease extremely.

Next, the area inside the inner circumference I3 when the aperture DP is narrowed will be described (the third condition). FIG. 24 is a cross-sectional view showing a part of the liquid crystal panel PNL of the second embodiment and the position of the camera 1a. In order to simplify the drawing, in the liquid crystal panel PNL, the first light shielding portion BM1 and the third light shielding portion BM3 are shown by solid lines, and the liquid crystal layer LC other than the first light shielding portion BM1 and the third light shielding portion BM3 is shown by dotted lines. Here, it is also defined and explained on a virtual plane including the central axis AX1 and the orthogonal axis AX2.

As shown in FIG. 24, a straight line that passes through the first point P1 and is parallel to the central axis AX1 is referred to as a sixth reference line RF6. A straight line passing through the third point P3 and parallel to the central axis AX1 is referred to as the seventh reference line RF7. The point where the sixth reference line RF6 intersects the liquid crystal layer LC is referred to as the tenth point P10. The point where the seventh reference line RF7 intersects with the liquid crystal layer LC is referred to as the eleventh point P11.

Since the fourth reference line RF4 and the central axis AX1 intersect at an angle θ, the triangle with the first point P1, the eighth point P8, and the tenth point P10 as the vertices, and the fifth point P5, the first point P1, and the It is similar to the triangle whose vertex is set at the sixth point P6. In addition, since the fifth reference line RF5 also crosses the central axis AX1 at an angle θ, the triangle with the third point P3, the ninth point P9, and the eleventh point P11 as the vertices, and the fifth point P5 and the third point The point P3 and the sixth point P6 are similar to the triangles whose vertices are set.

The linear distance between the first point P1 and the tenth point P10 is the second distance DT2. In addition, the linear distance between the eighth point P8 and the tenth point P10 and the linear distance between the ninth point P9 and the eleventh point P11 are respectively set as the distance DT4/2. Let the linear distance twice the distance DT4/2 be the fourth distance DT4. If yes, The relationship of DT4/DT2=DI2/DT1 is established, DT4=DI2×(DT2/DT1).

According to the relationship of DT4=DI2-DI3, DI2×(DT2/DT1)=DI2-DI3, DI2(1-DT2/DT1)=DI3, The relationship of DI3/DI2=1-(DT2/DT1) is established.

In the case where the second distance DT2 is set to 50% of the first distance DT1, DI3/DI2=0.5.

In this case, since the radius becomes 50%, the area inside the inner circumference I3 of the third light shielding portion BM3 becomes 0.25% of the area of the effective opening EA.

Furthermore, when the second distance DT2 is set to 60% of the first distance DT1, DI3=0.4×DI2, the area inside the inner circumference I3 becomes 0.16% of the area of the effective opening EA.

also, Since the relationship of DT4=DI2×(DT2/DT1) is established, in the case of DT2=DT1, DT4=DI2, and the area inside the inner circumference of I3 becomes 0. Therefore, in order to realize the opening inside the inner circumference I3, the first distance DT1 must be longer than the second distance DT2 (DT1>DT2).

Next, the relationship between the inner diameter DI1 of the first light shielding portion BM1 and the inner diameter DI3 of the third light shielding portion BM3 will be described. FIG. 25 is another cross-sectional view showing a part of the liquid crystal panel PNL of the second embodiment and the position of the camera 1a. In order to simplify the drawing, in the liquid crystal panel PNL, the first light shielding portion BM1 and the third light shielding portion BM3 are shown by solid lines, and the liquid crystal layer LC other than the first light shielding portion BM1 and the third light shielding portion BM3 is shown by dotted lines. Here, it is also defined and explained on a virtual plane including the central axis AX1 and the orthogonal axis AX2.

As shown in Fig. 25, the triangle with the first point P1, the eighth point P8, and the tenth point P10 as the vertices, and the triangle with the fifth point P5, the second point P2, and the seventh point P7 as the vertices Become similar. In addition, the triangle with the third point P3, the ninth point P9, and the eleventh point P11 as vertices is similar to the triangle with the fifth point P5, the fourth point P4, and the seventh point P7 as the vertices.

According to the above, The relationship of DT4/DT2=DI1/DT3 is established, DT4=(DI1×DT2)/DT3. According to the relationship of DI3=DI1-(2×DT4), DI3=DI1-(2×DI1×DT2)/DT3, The relationship of DI3/DI1=1-(2×DT2)/DT3 is established.

For example, when the second distance DT2 is 25% of the third distance DT3, DI3=0.5×DI1.

Furthermore, when the second distance DT2 is 50% of the first distance DT1, the third distance DT3 becomes 150% of the first distance DT1. Since the second distance DT2 becomes 1/3 of the third distance DT3, DI3=DI1/3.

26 is a plan view and a cross-sectional view showing the incident light control area PCA of the liquid crystal panel PNL of the second embodiment and the camera 1a. In the top view, the liquid crystal panel PNL is in the front, and the camera 1 is in the depth. Here, the case where the inner diameter DI3 of the third light shielding portion BM3 is set to 1/3 of the inner diameter DI1 of the first light shielding portion BM1 is shown.

As shown in FIG. 26, for example, when the inner diameter DI1 is 1.8 mm, the inner diameter DI3 of the third light shielding portion BM3 is 0.6 mm. Also shown in FIG. 8, inside the inner circumference I3 of the third light shielding portion BM3, a second opening OP2 (second incident light control area TA2) surrounded by the second light shielding portion BM2 is provided. The second opening OP2 is, for example, an opening with a diameter of 0.2 mm for pinhole photography. Therefore, the inner diameter DI4 of the second light shielding portion BM2 shown in FIG. 8 becomes 0.2 mm.

A light source EM3 is arranged between the inner diameter DI3 on the side of the camera 1a and the effective opening EA. Since the diameter of the effective opening EA is 1.2 mm, the distance between the inner diameter DI1 and the effective opening EA becomes 300 μm, so the length of the light source EM3 in the radial direction is preferably 300 μm or less. As described later, as the light source EM3, a mini LED with a long side length of 200-250 μm can be used. In addition, the size of the light source EM2 may be the same as the size of the light source EM3, or may be different from the size of the light source EM3.

A protrusion 500 is formed between the light sources EM2 and EM3 and the effective opening EA. The protrusion 500 can shield the light (visible light and infrared light) from the light sources EM2 and EM3 toward the effective opening EA. The slope on the side of the effective opening EA of the protrusion 500 is formed outside the first reference line RF1 and the second reference line RF2 so as not to shield the incident light. The light sources EM2 and EM3 are arranged on the oblique side 550 from the protrusion to the outside. The oblique side faces the inner side (the effective opening EA side) so that the light from the light sources EM2 and EM3 faces the second opening OP2.

FIG. 27 is a cross-sectional view showing the incident light control area PCA of the liquid crystal panel PNL of the second embodiment and the camera 1a, and is a diagram showing a variation of the camera 1a. In addition, FIG. 27 shows that when light from the light sources EM2 and EM3 is incident on the camera 1a, it is a problem that the protrusion 500 is extended to be as close as possible to the liquid crystal panel PNL.

As shown in FIG. 27, a part of the light emitted from the light source EM2 is reflected by the liquid crystal panel PNL, and is reflected into the camera as noise toward the effective opening EA. The protrusion 500 described in FIG. 27 shields the light toward the effective opening EA by minimizing the gap with the liquid crystal panel PNL. In FIG. 27, in order to improve the operability of installing the light sources EM2 and EM3 on the camera 1a, the light sources EM2 and EM3 are arranged on a surface parallel to the liquid crystal panel PNL. The second opening OP2 used as a pinhole is a relatively small opening. Therefore, the light passing through the second opening OP2 can be used to position the liquid crystal panel PNL and the camera 1a.

Next, the positioning of the liquid crystal panel PNL and the camera 1 will be described. FIG. 28 is a cross-sectional view showing a part of the liquid crystal panel PNL, a part of the lighting device IL, and the camera 1a of the second embodiment.

As shown in FIG. 28, light enters the camera 1 from the opening of the area limited by the diaphragm DP. Therefore, if the center of the incident light control area PCA is offset from the center axis AX1 of the optical system 2, there is a problem that the required light (visible light) does not reach the imaging surface 3a. Therefore, it is necessary to accurately position the center of the incident light control area PCA and the central axis AX1.

Therefore, in order to improve the positioning accuracy, the second opening OP2 with the smallest opening among the openings of the area PCA is controlled by the incident light. That is, the aperture DP is further narrowed (the second condition), and in the incident light control area PCA, the second incident light control area TA2 is set to a transmission state, and the first incident light control area TA1 and the third incident light control area TA3 are set It is non-transmissive state (Figure 8).

By vertically irradiating the liquid crystal panel PNL with parallel light such as laser light or LED light, the light passing through the second opening OP2 (second incident light control area TA2) can be detected on the imaging surface 3a. Furthermore, based on the intensity of the light in the area through which the central axis AX1 in the imaging surface 3a passes, it is possible to measure the degree to which the center of the incident light control area PCA coincides with the central axis AX1 and perform positioning.

If the center of the incident light control area PCA and the central axis AX1 can be positioned with high accuracy, the peripheral gap PG between the camera 1a and the light shielding wall CS2 can be narrowed. Here, the peripheral gap PG means the gap between the camera 1a and the light-shielding wall CS2 in a direction parallel to the third reference line RF3. Thereby, the size of the aperture DP (incident light control area PCA) including the first light shielding portion BM1 can be reduced.

Therefore, in order to narrow the peripheral gap PG, the inner diameter DI4 (diameter of the second opening OP2) of the second light shielding portion BM2 is preferably sufficiently shorter than the peripheral gap PG (DI4<PG) (FIG. 8 ).

In addition, the inner diameter DI4 is preferably 0.1 mm or more (0.1 mm≦DI4) in order to prevent the diffraction of light (Figure 8).

Next, using FIG. 29, the mini LED 200 used as the light source EM2 and EM3 will be described. Fig. 29 is a cross-sectional view showing the light source of the second embodiment.

As shown in FIG. 29, the mini LED 200 is a flip-chip type light emitting diode device, which has a transparent substrate 210 with insulation. The substrate 210 is, for example, a sapphire substrate. On the surface 220 of the substrate 210, a crystalline layer (semiconductor layer) in which an n-type semiconductor layer 120, an active layer (light emitting layer) 130, and a p-type semiconductor layer 140 are sequentially laminated is formed. In the aforementioned crystalline layer (semiconductor layer), the region containing P-type impurities is the p-type semiconductor layer 140, and the region containing N-type impurities is the n-type semiconductor layer 120. The material of the crystalline layer (semiconductor layer) is not particularly limited, but the crystalline layer (semiconductor layer) may include gallium nitride (GaN) or gallium arsenide (GaAs).

The reflective film 150 is formed of a conductive material and is electrically connected to the p-type semiconductor layer 140. The p electrode 160 is electrically connected to the reflective film 150. The n electrode 180 is electrically connected to the n-type semiconductor layer 120. The pad 230 covers the n electrode 180 and is electrically connected to the n electrode 180. The protective layer 170 covers the n-type semiconductor layer 120, the active layer 130, the p-type semiconductor layer 140, and the reflective film 150, and covers a part of the p electrode 160. The pad 240 covers the p-electrode 160 and is electrically connected to the p-electrode 160.

The length of the horizontal direction of the mini LED 200 in the figure, that is, the length of one side exceeds, for example, 100 μm and does not reach 300 μm. The luminous frequency of the mini LED 200 can be used as visible light, which is between 400 nm and 700 nm, and can also be used as infrared light, which is between 800 nm and 1500 nm.

By having a light source EM2 that emits infrared light and a light source EM3 that emits visible light, one camera 1a can realize photography by visible light and photography by infrared light. For example, the aperture DP may function as a pinhole, and in parallel with close-up photography for fingerprint authentication, vein authentication by infrared light may be performed.

According to the electronic device 100 of the second embodiment configured as described above, it is possible to obtain the electronic device 100 capable of performing photography satisfactorily.

(Third Embodiment) Next, the third embodiment will be described. The electronic device 100 has the same configuration as the above-mentioned first embodiment except for the configuration related to the longitudinal electric field mode described in the third embodiment. Here, the case where the electrodes in the longitudinal electric field mode constitute the incident light control area PCA will be described. FIG. 30 is a cross-sectional view showing a part of the liquid crystal panel PNL of the electronic device 100 of the third embodiment. In addition, in FIG. 30, the vicinity of the boundary between the display area DA and the incident light control area PCA is displayed. In addition, only the components required for the description in the liquid crystal panel PNL are displayed, and the illustration of the above-mentioned alignment films AL1, AL2, etc. is omitted.

As shown in FIG. 30, in the configuration of the vertical electric field mode, in addition to the control electrode structure RE provided on the insulating substrate 10, the insulating substrate 20 is also provided with a counter electrode OE. In the longitudinal electric field mode, the liquid crystal layer LC of the incident light control area PCA is driven by a voltage applied between the control electrode structure RE and the counter electrode OE.

A plurality of spacers SP are provided between the insulating substrate 10 and the insulating substrate 20. The first gap Ga1 between the first substrate SUB1 and the second substrate SUB2 in the display area DA and the second gap Ga2 between the first substrate SUB1 and the second substrate SUB2 in the incident light control area PCA are held by a plurality of spacers SP . In the display area DA, the spacer SP is covered by the light-shielding part BMA2 (light-shielding part BMA). In the incident light control area PCA, the spacer SP is covered by the second light shielding portion BM2 or the third light shielding portion BM3.

In the incident light control area PCA, the first control liquid crystal layer LC1, the second control liquid crystal layer LC2, and the third control liquid crystal layer LC3 are driven in the ECB (Electrically Controlled Birefringence) mode in the longitudinal electric field mode. Therefore, the λ/4 plate QP2 is sandwiched between the polarizing plate PL2 and the insulating substrate 20, and the λ/4 plate QP1 is sandwiched between the polarizing plate PL1 and the insulating substrate 10.

In the display area DA and the incident light control area PCA, the polarizing plate PL1 and the polarizing plate PL2 are respectively common. The easy transmission axis (polarization axis) of each of the polarizing plate PL1 and the polarizing plate PL2 faces the same direction in the display area DA and the incident light control area PCA. The easy transmission axis of the polarizing plate PL1 is orthogonal to the easy transmission axis of the polarizing plate PL2.

On the other hand, in the display area DA, the display liquid crystal layer LCI is driven in a lateral electric field mode. Although the display liquid crystal layer LCI is driven in the FFS mode, it can be driven in the IPS mode. In the display area DA, in the state where no voltage is applied between the pixel electrode PE and the common electrode CE, the alignment axis (phase advance axis) of the liquid crystal molecules is orthogonal to the easy transmission axis of the polarizing plate PL1 (or the polarizing plate PL2) , Or parallel. Therefore, since there is no phase difference in the display liquid crystal layer LCI when no voltage is applied to the display liquid crystal layer LCI, the light is blocked (normally black) because the easy transmission axis of the polarizing plate PL2 and the polarizing plate PL1 are orthogonal to each other. Way).

If a voltage is applied between the pixel electrode PE and the common electrode CE, the liquid crystal molecules rotate, and the phase advance axis of the liquid crystal molecules has an angle with respect to the polarization direction of linear polarization, resulting in a phase difference. In the display liquid crystal layer LCI, when the liquid crystal molecules rotate (the phase advance axis is inclined by 45° with respect to the polarization direction), the birefringence Δn and the gap Ga (Δn×Ga=1/ 2λ). The light passing through the display liquid crystal layer LCI changes from the linearly polarized light parallel to the easy transmission axis of the polarizing plate PL1 to the linearly polarized light inclined by 90° with respect to the easy transmission axis of the polarizing plate PL1. Therefore, in the display area DA, light is transmitted by applying a voltage between the pixel electrode PE and the common electrode CE.

In the display area DA and the incident light control area PCA, the same liquid crystal layer LC and polarizing plates PL1 and PL2 are used, and the alignment axes of the liquid crystal molecules are also in the same direction. Therefore, the phase difference of the liquid crystal layer LC is also the same, and the direction of the alignment deviation of the liquid crystal molecules with respect to the easy transmission axis of the axial polarizing plates PL1 and PL2 is also the same.

Therefore, in the incident light control area PCA, the λ/4 plate QP2 and the λ/4 plate QP1 are sandwiched between the polarizing plate PL2 and the polarizing plate PL1. The phase lag axis of the λ/4 plate QP2 is inclined 45° with respect to the easy transmission axis of the polarizer PL2, and the phase lag axis of the λ/4 plate QP1 is inclined 45° with respect to the easy transmission axis of the polarizer PL1. The light passing through the λ/4 plate QP2 and the λ/4 plate QP1 changes from linearly polarized light to circularly polarized light, or changes from circularly polarized light to linearly polarized light.

The phase lag axis of the λ/4 plate QP1 is inclined by +45ﾟ relative to the easy transmission axis of the polarizer PL1, and the linearly polarized light emitted from the polarizer PL1 changes to a clockwise circular polarized light. In the first control liquid crystal layer LC1, the second control liquid crystal layer LC2, and the third control liquid crystal layer LC3, the birefringence Δn and the second gap Ga2 (Δn×Ga2=1/2λ) are adjusted so that the phase difference becomes π ), from the circularly polarized light that rotates clockwise to the circularly polarized light that rotates counterclockwise.

The phase lag axis of the λ/4 plate QP2 is inclined -45ﾟ with respect to the easy transmission axis of the polarizer PL1, and the light passing through the λ/4 plate QP2 becomes linearly polarized light that is inclined 90ﾟ with respect to the easy transmission axis of the polarizer PL1 and passes through Polarizing plate PL2.

The first substrate SUB1 is provided with a control electrode structure group REG located in the incident light control area PCA and including a plurality of control electrode structures RE. The second substrate SUB2 has a counter electrode OE located in the incident light control region PCA and facing the control electrode structure group REG. Therefore, in the incident light control region PCA, light is transmitted in a state where no voltage is applied between the control electrode structure RE and the counter electrode OE (normally white method). In addition, the second substrate SUB2 has a transparent layer TL in the incident light control area PCA instead of the color filter CF.

In the ECB mode, by applying a voltage between the control electrode structure RE and the counter electrode OE, the liquid crystal molecules are aligned along the direction perpendicular to the first substrate SUB1 and the second substrate SUB2, and the liquid crystal molecules are The birefringence (Δn) changes to control the amount of transmitted light.

By applying a voltage between the control electrode structure RE and the counter electrode OE, the long axis direction of the liquid crystal molecules is along the direction perpendicular to the first substrate SUB1 and the second substrate SUB2, and the birefringence of the transmitted light is reduced. The amount of transmitted light is reduced.

For example, if the birefringence Δn becomes 0 and the phase difference becomes 0, the light passing through the first control liquid crystal layer LC1, the second control liquid crystal layer LC2, and the third control liquid crystal layer LC3 is a clockwise circularly polarized light that does not change. The clockwise circularly polarized light of the λ/4 plate QP2 becomes linearly polarized light that is parallel to the easy transmission axis of the polarizer PL1, and does not pass through the polarizer PL2. Therefore, by applying a voltage between the control electrode structure RE and the counter electrode OE, the light incident on the camera 1 (non-transmissive state) can be reduced by the diaphragm DP.

Furthermore, the boundaries of the first range TA1a and the second range TA1b, the boundaries of the third range TA2a and the fourth range TA2b, and the boundaries of the fifth range TA3a and the sixth range TA3b are aligned in the direction X.

The incident light control area PCA can be divided into a first area A1 and a second area A2 according to the diameter of a circle formed by the outer circumference of the first light shielding portion BM1. In the third embodiment, the first area A1 includes a first range TA1a, a third range TA2a, and a sixth range TA3b. The second area A2 includes a second area TA1b, a fourth area TA2b, and a fifth area TA3a.

However, the method of dividing each of the first incident light control area TA1, the second incident light control area TA2, and the third incident light control area TA3 into two ranges is the one exemplified in the third embodiment, and various changes can be made. .

Furthermore, in the orthogonal direction dc3, the width WDo of the linear counter electrode OML is 390 μm, and the fourth gap SC4 is 10 μm.

In addition, the pitch of the orthogonal direction dc3 of the first control electrode RL1 and the second control electrode RL2 and the pitch of the linear counter electrode OML can be set randomly as in the above-mentioned first embodiment (FIG. 10).

When the first control electrode structure RE1, the second control electrode structure RE2, and the counter electrode OE are driven under the first condition (the condition for opening the diaphragm DP), the liquid crystal panel PNL sets the first incident light control area TA1 to transmit state. The first control voltage applied to the first control electrode structure RE1 and the second control voltage applied to the second control electrode structure RE2 are respectively the same as the counter voltage applied to the counter electrode OE.

On the other hand, when the third condition (the condition for narrowing the aperture DP), the second condition (the condition for further narrowing the aperture DP), and the fourth condition (the condition for closing the aperture DP) are driven In the case of 1 control electrode structure RE1, second control electrode structure RE2, and counter electrode OE, the liquid crystal panel PNL sets the first incident light control area TA1 to a non-transmitting state.

If attention is paid to a part of the period in which the first control liquid crystal layer LC1 is driven, one of the first control voltage and the second control voltage is more positive than the counter voltage. During this period, the other control voltage of the first control voltage and the second control voltage is negative than the opposite voltage. For the counter voltage, the polarity of the first control voltage is different from the polarity of the second control voltage.

Therefore, the polarity of the voltage generated between the first control electrode structure RE1 and the counter electrode OE and applied to the first control liquid crystal layer LC1, and the polarity of the voltage generated between the second control electrode structure RE2 and the counter electrode OE and applied to the first control liquid crystal layer LC1 The polarity of the voltage of the first control liquid crystal layer LC1 is different from each other. The influence of the potential fluctuation of the counter electrode OE caused by the potential fluctuation of the first control electrode structure RE1 and the influence of the potential fluctuation of the counter electrode OE caused by the potential fluctuation of the second control electrode structure RE2 cancel each other out. Thereby, it is possible to suppress the undesired potential fluctuation of the counter electrode OE.

In the third embodiment, the absolute value of the difference between the counter voltage and the first control voltage is the same as the absolute value of the difference between the counter voltage and the second control voltage. Therefore, it is possible to further suppress the unintended potential fluctuation of the counter electrode OE.

In addition, unlike the third embodiment, since the first control voltage and the second control voltage with respect to the counter voltage have the same polarity, an undesirable potential change of the counter electrode OE is caused, so it is not Satisfactory.

As described above, during the period during which the first control liquid crystal layer LC1 is driven under the second to fourth conditions, the polarity of the first control voltage and the polarity of the second control voltage can be reversed based on the counter voltage.

The fifth gap SC5 is aligned with the above-mentioned third gap SC3 in the third extending direction d3 (FIGS. 32 and 35 ).

When the third control electrode structure RE3, the fourth control electrode structure RE4, and the counter electrode OE are driven under the first, second, and third conditions, the liquid crystal panel PNL sets the second incident light control area TA2 to transmit state. The third control voltage applied to the third control electrode structure RE3 and the fourth control voltage applied to the fourth control electrode structure RE4 are respectively the same as the counter voltage applied to the counter electrode OE.

On the other hand, when the third control electrode structure RE3, the fourth control electrode structure RE4, and the counter electrode OE are driven under the fourth condition, the liquid crystal panel PNL sets the second incident light control area TA2 to a non-transmitting state.

If attention is paid to a part of the period during which the second control liquid crystal layer LC2 is driven, one of the third control voltage and the fourth control voltage is more positive than the counter voltage. During this period, the other control voltage of the third control voltage and the fourth control voltage is negative than the opposite voltage.

Therefore, the polarity of the voltage generated between the third control electrode structure RE3 and the counter electrode OE and applied to the second control liquid crystal layer LC2, and the polarity of the voltage generated between the fourth control electrode structure RE3 and the counter electrode OE and applied to the second control liquid crystal layer LC2 The polarity of the voltage of the second control liquid crystal layer LC2 is different from each other. In the third embodiment, the absolute value of the difference between the counter voltage and the third control voltage is the same as the absolute value of the difference between the counter voltage and the fourth control voltage.

In addition, unlike the third embodiment, since the third control voltage and the fourth control voltage with respect to the counter voltage have the same polarity, an undesirable potential change of the counter electrode OE is caused, so it is not Satisfactory.

As described above, during the period when the second control liquid crystal layer LC2 is driven under the fourth condition, the polarity inversion driving can be performed in which the polarity of the third control voltage and the polarity of the fourth control voltage are inverted on the basis of the counter voltage. During the above period, the opposing voltage is a constant voltage. In addition, when the third control electrode structure RE3 and the fourth control electrode structure RE4 are driven under the first condition, the third control electrode can be synchronized with the polarity inversion drive of the first control electrode structure RE1 and the second control electrode structure RE2. Structure RE3 and the fourth control electrode structure RE4 polarity inversion drive.

In addition, the positional relationship between the fifth gap SC5 and the linear counter electrode OML is as described above. Therefore, it can be compared with the case where the electric field generated between the third control electrode RL3 and the linear counter electrode OML and the electric field generated between the fourth control electrode RL4 and the linear counter electrode OML is parallel to the direction Z Further control the rising direction of the liquid crystal molecules of the second control liquid crystal layer LC2.

During this period, the other control voltage of the fifth control voltage and the sixth control voltage is more negative than the opposite voltage.

Therefore, the polarity of the voltage generated between the fifth control electrode structure RE5 and the counter electrode OE and applied to the third control liquid crystal layer LC3, and the polarity of the voltage generated between the sixth control electrode structure RE4 and the counter electrode OE and applied to The polarity of the voltage of the third control liquid crystal layer LC3 is different from each other. In the third embodiment, the absolute value of the difference between the counter voltage and the fifth control voltage is the same as the absolute value of the difference between the counter voltage and the sixth control voltage.

In addition, unlike the third embodiment, in the case where the polarity of each of the fifth control voltage and the sixth control voltage for the counter voltage is the same, an undesirable potential change of the counter electrode OE is caused, so it is not Satisfactory.

The first substrate SUB1 further has a plurality of pads PD including a first pad PD1, a second pad PD2, a third pad PD3, a fourth pad PD4, a fifth pad PD5, a sixth pad PD6, a seventh pad PD7, and so on. The pads PD are located in the extended portion Ex in the first non-display area NDA1 of the first substrate SUB1, and are aligned in the direction X.

The first routing wiring L1, the second routing wiring L2, the third routing wiring L3, the fourth routing wiring L4, the fifth routing wiring L5, and the sixth routing wiring L6 are placed in the incident light control area PCA, display The area DA and the non-display area NDA extend. In the sixth embodiment, the aperture DP (incident light control area PCA) is provided at a position near the second non-display area NDA2 among the first to fourth non-display areas NDA1 to NDA4. Therefore, the first to sixth routing wires L1 to L6 detour in the display area DA and extend in the non-display area NDA in such a way that the distance extending in the display area DA becomes as short as possible.

Here, the connection relationship between the control electrode structure RE and the pad (connection terminal) PD will be described.

As shown in FIGS. 44 and 32, the first routing wiring L1 electrically connects the first control electrode structure RE1 located in the first incident light control area TA1 to the first pad PD1. The second routing wiring L2 electrically connects the second control electrode structure RE2 located in the first incident light control area TA1 to the second pad PD2.

Among the above-mentioned first to sixth routing wirings L1 to L6, the portion of the display area DA between the non-display area NDA and the incident light control area PCA is called the routing wiring, and will be located in the non-display area The part of NDA is called peripheral wiring. In this case, the aforementioned routing wire is connected to the corresponding control electrode RL via the corresponding wire WL. In addition, the peripheral wiring extends between the corresponding pad PD and the corresponding routing wiring in the non-display area NDA, and is connected to the corresponding pad PD and the corresponding routing wiring.

In addition, the aperture DP (incident light control area PCA) may not be provided in the vicinity of the second non-display area NDA2. For example, the aperture DP (incident light control area PCA) can be arranged at a position near the third non-display area NDA3 among the first to fourth non-display areas NDA1 to NDA4. In this case, the first to sixth routing wires L1 to L6 may extend only in the third non-display area NDA3 and the first non-display area NDA1 in the non-display area NDA.

Although as described above, in the sixth embodiment, the lead wire L is used to apply voltage to the control electrode structure RE, but the liquid crystal panel PNL only needs to be able to apply voltage to the control electrode structure RE, and the lead wire L is not required. And constitute. For example, the control electrode structure RE can be electrically connected to the IC chip 6 by using several signal lines S of the plurality of signal lines S (FIG. 3 ), and the control electrode structure RE can be driven via the signal line S dedicated to the control electrode structure RE.

The routing wiring Lo is electrically connected to the ninth pad PD9 (Figure 33).

For example, the routing wiring Lo extends in the second non-display area NDA2, the fourth non-display area NDA4, and the first non-display area NDA1 in the same manner as the second routing wiring L2, and electrically connects the counter electrode OE to Pad 9 PD9. The eighth pad PD8 and the ninth pad PD9 are electrically connected by a conductive member not shown. Thereby, it is possible to apply a counter voltage to the counter electrode OE via the seventh pad PD7, the connection wiring CO, the eighth pad PD8, the ninth pad PD9, the routing wiring Lo, and the like.

Here, the relationship between the counter voltage applied to the counter electrode OE and the first to sixth control voltages applied to the first to sixth control electrode structures RE1 to RE6 will be described.

As shown in FIG. 44, FIG. 35, FIG. 37, and FIG. 39, under the above-mentioned first condition, the first to sixth control voltages are the same as the counter voltage, respectively. For example, in any period under the above-mentioned first condition, the first to sixth control voltages and the counter voltage are each 0V. The liquid crystal panel PNL can set the first to third incident light control regions TA1 to TA3 to a transmission state.

In this case, there is substantially no influence of the voltage on the third non-display area NDA3 due to the first routing wiring L1, the third routing wiring L3, and the sixth routing wiring L6, and the second routing wiring L2, the fourth routing wiring L4, and the fifth routing wiring L5 allow him to influence the voltage caused by the fourth non-display area NDA4.

Under the above second condition, the polarity of the first control voltage and the polarity of the second control voltage are different from each other with respect to the opposite voltage. That is, the polarity of the first control voltage and the polarity of the second control voltage are opposite polarities. The polarity of the fifth control voltage and the polarity of the sixth control voltage are different from each other with respect to the opposite voltage. The third control voltage and the fourth control voltage are the same as the counter voltage. For example, in any period under the above-mentioned second condition, the third control voltage, the fourth control voltage, and the counter voltage are each 0 V, the first control voltage and the fifth control voltage are respectively +α V, and the second control voltage is +α V. The control voltage and the sixth control voltage are -αV, respectively. The liquid crystal panel PNL can set the second incident light control area TA2 to a transmissive state, and set the first incident light control area TA1 and the third incident light control area TA3 to a non-transmissive state.

In this case, the first routing wiring L1 and the sixth routing wiring L6 are set to opposite polarities, and the second routing wiring L2 and the fifth routing wiring L5 are set to opposite polarities. Therefore, compared with the case where the polarity of the first routing wire L1 and the polarity of the sixth routing wire L6 are the same, the polarity of the second routing wire L2 and the fifth routing wire L are the same, which can suppress the possibility of the third non-display The influence of the voltage caused by the area NDA3 and the fourth non-display area NDA4.

Under the above-mentioned third condition, the polarity of the first control voltage and the polarity of the second control voltage are different from each other with respect to the opposite voltage. The third control voltage, the fourth control voltage, the fifth control voltage, and the sixth control voltage are the same as the counter voltage. For example, in any period under the third condition, the third control voltage, the fourth control voltage, the fifth control voltage, the sixth control voltage, and the counter voltage are each 0 V, and the first control voltage is +α V, the second control voltage is -αV. The liquid crystal panel PNL can set the second incident light control area TA2 and the third incident light control area TA3 to a transmissive state, and the first incident light control area TA1 to a non-transmitting state.

In this case, the 3rd routing wire L3 and the 6th routing wire L6 are set to 0V, and the 4th routing wire L4 and the 5th routing wire L5 are set to 0V. Therefore, under the above-mentioned third condition, the lead wire L may have less influence on the voltage caused by the third non-display area NDA3 and the fourth non-display area NDA4.

Under the above-mentioned fourth condition, the polarity of the first control voltage and the polarity of the second control voltage are different from each other with respect to the opposite voltage. The polarity of the fifth control voltage and the polarity of the sixth control voltage are different from each other with respect to the opposite voltage. The polarity of the third control voltage and the polarity of the fourth control voltage are different from each other with respect to the opposite voltage. For example, in any period under the above-mentioned fourth condition, the first control voltage, the third control voltage, and the fifth control voltage are respectively +α V, and the second control voltage, the fourth control voltage, and the sixth control voltage They are -α V respectively. The liquid crystal panel PNL can set the first to third incident light control regions TA1 to TA3 to a non-transmissive state.

In this case, the polarity of the first wiring L1, the polarity of the third wiring L3, and the polarity of the sixth wiring L6 are not the same, the polarity of the second wiring L2 and the polarity of the fourth wiring L4 The polarity and the polarity of the fifth lead wire L5 are also not the same. Therefore, compared with the case where the above-mentioned polarity becomes the same, it is possible to suppress the influence of the voltage that may be caused on the third non-display area NDA3 and the fourth non-display area NDA4.

As described above, the capacitance caused by the routing wiring L is balanced in the third non-display area NDA3 and the fourth non-display area NDA4. For example, it is possible to suppress adverse effects on the third non-display area NDA3 and the fourth non-display area NDA4.

According to the liquid crystal display device DSP and the electronic device 100 of the sixth embodiment configured as described above, it is possible to obtain the liquid crystal display device DSP and the electronic device 100 capable of controlling the light transmission area of the incident light control area PCA. In addition, it is possible to obtain an electronic device 100 that can perform photography satisfactorily.

(The seventh embodiment) Next, the seventh embodiment will be described. FIG. 45 is a plan view showing the scanning line G and the signal line S in the incident light control area PCA of the liquid crystal panel PNL of the electronic device 100 of the seventh embodiment. In FIG. 45, the scanning line G is represented by a solid line, the signal line S is represented by a broken line, and the inner and outer circumferences of the first light-shielding area LSA1 are represented by two-dot chain lines, respectively. In addition, only the necessary components are illustrated in FIG. 45. The electronic device 100 of the seventh embodiment has the same configuration as the electronic device 100 of any one of the above-mentioned first to sixth embodiments except for the wiring of the scanning line G and the signal line S in the incident light control area PCA .

As shown in FIG. 45, a plurality of scanning lines G are arranged in the direction Y with an interval of 60 to 180 μm in the display area DA. The plurality of signal lines S are arranged in the direction X at intervals of 20 to 60 μm. The scan line G and the signal line S also extend in the incident light control area PCA, respectively.

One or more of the scanning lines G and the plurality of signal lines S extending toward the first incident light control area TA1 and extending over the display area DA detour in the first incident light control area TA1 and in the incident light control area PCA The first light-shielding area LSA1 is extended. Therefore, when the diameter of the outer circumference of the first light-shielding area LSA1 (first light-shielding portion BM1) is 6 to 7 mm, 30 to 120 of the scanning lines G and 100 to 350 of the signal lines S avoid the first incident The light control area TA1 is arranged in the first light shielding area LSA1 covered by the first light shielding portion BM1. Therefore, even if there is the incident light control area PCA surrounded by the display area DA, the scanning lines G, the signal lines S, and the like can be well wired.

According to the liquid crystal display device DSP and the electronic device 100 of the seventh embodiment configured as described above, since the electronic device 100 is configured in the same manner as the electronic device 100 of the aforementioned embodiment, the same effect as the aforementioned embodiment can be obtained. In addition, it is possible to obtain an electronic device 100 that can perform photography satisfactorily.

(Eighth Embodiment) Next, the eighth embodiment will be described. Here, the case where the aperture DP is used as a shutter will be described. First, the relationship between the gap Ga of the liquid crystal layer LC and the transmittance and response speed will be described. 46 is a graph showing the change in the transmittance of light (visible light) to the gap Ga of the liquid crystal layer LC and the change in the response speed of the liquid crystal to the gap Ga in the liquid crystal panel PNL of the electronic device 100 of the eighth embodiment.之图. The electronic device 100 has the same configuration as the above-mentioned third embodiment (FIG. 30) except for the configuration described in the eighth embodiment.

The relationship between the gap Ga shown in FIG. 30 and the response speed of the liquid crystal is shown in FIG. 46. It can be seen that the narrower the gap Ga, the faster the response speed of the liquid crystal. In addition, in this specification, the so-called response speed of the liquid crystal means the transition of the liquid crystal molecules from the initial alignment to a specific state, which means the speed at which the liquid crystal molecules rise. Therefore, in the eighth embodiment, the second gap Ga2 is set to be less than the first gap Ga1 (Ga2<Ga1). A case where the second gap Ga2 is set to a half of the first gap Ga1 (Ga2=Ga1/2) can be exemplified.

Thereby, the response speed of the liquid crystal of the display liquid crystal layer LCI of the display area DA can be increased to increase each of the first control liquid crystal layer LC1, the second control liquid crystal layer LC2, and the third control liquid crystal layer LC3 of the incident light control area PCA The response speed of the liquid crystal. For example, the incident light control area PCA (aperture DP) of the liquid crystal panel PNL can function as a liquid crystal shutter.

There are also cases where the shutter speed is required to be 0.001 seconds or less. In order to function as a liquid crystal shutter, the time for applying a voltage to the control electrode RL becomes shorter than the time for applying a voltage to the pixel electrode PE. Therefore, it is also required to increase the response speed of the liquid crystal driven by the control electrode RL.

However, as the second gap Ga2 is narrowed, the transmittance of the light entering the light control area PCA becomes lower, so care must be taken.

In addition, even if the first gap Ga1 is narrowed, the response speed of the liquid crystal of the display liquid crystal layer LCI can be increased. However, since the light transmittance of the display area DA becomes low, it means that the image becomes dark, so care must be taken.

Next, the relationship between the voltage applied to the liquid crystal layer LC and the response speed will be described. FIG. 47 is a graph showing the change in the response speed of the liquid crystal to the voltage applied to the liquid crystal layer LC in the eighth embodiment. In addition, in FIG. 47, the second gap Ga2 is set to 1.7 μm.

As shown in FIG. 47, it can be seen that the greater the potential difference between the control electrode structure RE and the counter electrode OE, the higher the response speed of the liquid crystal. In the case where the incident light control area PCA (aperture DP) functions as a liquid crystal shutter, the response speed of the liquid crystal is preferably 1.0 ms or less. It can be seen that in the case of obtaining the response speed of the liquid crystal below 1.0 ms, the voltage (the absolute value of the voltage) between the control electrode structure RE and the counter electrode OE must be 13 V or more.

For example, in the case where the first incident light control area TA1, the second incident light control area TA2, and the third incident light control area TA3 are respectively changed from the transmission state to the non-transmission state at a high speed, only the first control liquid crystal layer LC1 , The second control liquid crystal layer LC2 and the third control liquid crystal layer LC3 may be applied with a voltage of 13 V or more.

In addition, when the incident light control area PCA (aperture DP) functions as a liquid crystal shutter, the absolute value of the voltage applied to the first control liquid crystal layer LC1, the absolute value of the voltage applied to the second control liquid crystal layer LC2, And the absolute value of the voltage applied to the third control liquid crystal layer LC3 is higher than the absolute value of the voltage applied to the display liquid crystal layer LCI, respectively.

According to the above content, depending on the voltage, the response speed of the liquid crystal of each of the first control liquid crystal layer LC1, the second control liquid crystal layer LC2, and the third control liquid crystal layer LC3 of the incident light control area PCA can be higher than that of the display area DA. Displays the response speed of the liquid crystal of the liquid crystal layer LCI.

The incident light control area PCA (aperture DP) of the liquid crystal panel PNL can function as a first liquid crystal shutter by returning from the above-mentioned fourth condition to the fourth condition via the first condition. The liquid crystal panel PNL can be obtained by switching the first incident light control area TA1, the second incident light control area TA2, and the third incident light control area TA3 from the non-transmission state to the transmission state at the same time, and then returns to the non-transmission state. The first liquid crystal shutter.

When the first incident light control area TA1, the second incident light control area TA2, and the third incident light control area TA3 are returned from the transmission state to the non-transmission state as described above, the liquid crystal panel PNL reacts to the first control liquid crystal layer LC1 and the second 2 The control liquid crystal layer LC2, and the third control liquid crystal layer LC3 are simultaneously applied with a voltage of 13 V or more, and the first control liquid crystal layer LC1, the second control liquid crystal layer LC2, and the third control liquid crystal layer LC3 are simultaneously driven.

The incident light control area PCA (aperture DP) of the liquid crystal panel PNL can function as a second liquid crystal shutter by returning from the above-mentioned fourth condition to the fourth condition via the second condition. The liquid crystal panel PNL switches the second incident light control area TA2 from the non-transmissive state to the transmissive state and then returns to the non-transmissive state while maintaining the first incident light control area TA1 and the third incident light control area TA3 in the non-transmissive state. In the transmission state, a second liquid crystal shutter can be obtained. In the second liquid crystal shutter, the aperture DP can have both pinhole and shutter functions.

In addition, while the first incident light control area TA1 and the third incident light control area TA3 are kept in a non-transmissive state, the voltage applied to the first control liquid crystal layer LC1 and the third control liquid crystal layer LC3 may not reach 13V. For example, in order to maintain the non-transmissive state, the voltage applied to the first control liquid crystal layer LC1 and the third control liquid crystal layer LC3 may be at the same level as the voltage applied to the display liquid crystal layer LCI.

When the second incident light control area TA2 returns from the transmission state to the non-transmission state as described above, the liquid crystal panel PNL applies a voltage of 13 V or more to the second control liquid crystal layer LC2 to drive the second control liquid crystal layer LC2.

The incident light control area PCA (aperture DP) of the liquid crystal panel PNL can function as a third liquid crystal shutter by returning from the above-mentioned fourth condition to the fourth condition via the third condition. The liquid crystal panel PNL switches the second incident light control area TA2 and the third incident light control area TA3 from the non-transmissive state to the transmissive state at the same time while keeping the first incident light control area TA1 in the non-transmissive state. Return to the non-transmissive state, and a third liquid crystal shutter can be obtained. In the third liquid crystal shutter, the aperture DP can have both the function of narrowing the incident light and the function of a shutter.

In addition, since the aperture and shutter speed must be adjusted in order to obtain the desired image, the voltage applied to the first control liquid crystal layer LC1 may not be as high as the first incident light control area TA1 is maintained in a non-transmissive state 13 V.

When the second incident light control area TA2 and the third incident light control area TA3 return from the transmission state to the non-transmission state as described above, the liquid crystal panel PNL simultaneously applies 13 V to the second control liquid crystal layer LC2 and the third control liquid crystal layer LC3 The above voltages simultaneously drive the second control liquid crystal layer LC2 and the third control liquid crystal layer LC3.

As mentioned above, by making the incident light control area PCA (aperture DP) of the liquid crystal panel PNL function as a liquid crystal shutter, it is not limited to a stationary subject, and even a moving subject can be photographed well. . The liquid crystal panel PNL can control the light transmission area concentrically in the incident light control area PCA, and the incident light control area PCA can function as a liquid crystal shutter.

According to the electronic device 100 of the eighth embodiment having the above-mentioned configuration, it is possible to obtain the electronic device 100 capable of performing photography well.

The technique shown in this eighth embodiment can also be applied to other embodiments. For example, the technique of this eighth embodiment can be applied to the above-mentioned first embodiment. In the first embodiment described above, the method of the incident light control area PCA of the liquid crystal panel PNL is a normally black method. Therefore, when switching from the non-transmissive state to the transmissive state, the liquid crystal panel PNL only needs to apply a voltage of 13 V or more to the first control liquid crystal layer LC1, the second control liquid crystal layer LC2, and the third control liquid crystal layer LC3.

(Ninth Embodiment) Next, the ninth embodiment will be described. The electronic device 100 has the same configuration as the above-mentioned first embodiment except for the configuration described in the ninth embodiment. FIG. 48 is a plan view showing the liquid crystal panel PNL, the light guide body LG1, and the camera 1a of the electronic device 100 of the ninth embodiment. Regarding the liquid crystal panel PNL, the first light shielding portion BM1, the second light shielding portion BM2, the third light shielding portion BM3, and the light shielding portion BMB are displayed.

As shown in FIG. 48, the liquid crystal panel PNL includes: a display area DA, an incident light control area PCA including the outer periphery of the display area DA, an exit light control area ICA adjacent to the incident light control area PCA, and a non-display area NDA . The liquid crystal panel PNL is configured in the same manner in the display area DA and the emitted light control area ICA except for the color filter CF. The plurality of pixels PX are arranged in the same manner in the display area DA and the emitted light control area ICA. The coloring layer of the color filter CF is arranged in the display area DA, and is not arranged in the incident light control area PCA and the exit light control area ICA.

The incident light control area PCA is provided in the vicinity of the second non-display area NDA2. In the ninth embodiment, the emitted light control area ICA is surrounded by the display area DA, the incident light control area PCA, and the second non-display area NDA2 (light-shielding portion BMB).

The camera 1a includes at least one light source EM2 and at least one light source EM3. In this embodiment, the camera 1a includes a plurality of light sources EM2 and a plurality of light sources EM3. The light source EM3 is arranged in the emission light control area ICA. In addition, although the light source EM2 also overlaps the emission light control area ICA, it is not limited to this, and the light source EM2 may overlap the light shielding portion BMB or the like.

The light guide body LG1 overlaps the incident light control area PCA and the exit light control area ICA, and has a concave portion LGC that is recessed in the direction Y. The light guide LG1 overlaps the display area DA, but does not overlap the incident light control area PCA and the exit light control area ICA. The lighting device IL is configured to illuminate the display area DA in the liquid crystal panel PNL.

In addition, the light source EM3 of the camera 1a is configured to illuminate the emission light control area ICA in the liquid crystal panel PNL. The liquid crystal panel PNL is configured to selectively transmit visible light emitted from the light source EM3 in the emitted light control area ICA. The combination of the emission light control area ICA of the liquid crystal panel PNL and the light source EM3 is configured to display white or black.

By setting the emission light control area ICA of the liquid crystal panel PNL to black (non-transmissive state), the light sources EM2, EM3, etc. behind the liquid crystal panel PNL can be hidden. By setting the emission light control area ICA of the liquid crystal panel PNL to white (transmissive state), visible light from the light source EM3 can be emitted. For example, a fingerprint can be captured by the camera 1a.

In addition, the infrared light can be emitted from the light source EM2 as needed, and the infrared light can be received by the camera 1a, and the front of the screen of the liquid crystal display device DSP can be photographed.

In addition, the structure of the emission light control area ICA of the liquid crystal panel PNL can be changed in various ways.

For example, the colored layer of the color filter CF can be arranged in the emitted light control area ICA. Thereby, the emission light control area ICA of the liquid crystal panel PNL can correspond to the color display together with the light source EM3. However, the boundary between the display area DA and the emitted light control area ICA is likely to be conspicuous. In this case, it is only necessary to overlap the light guide body LG1 and the emitted light control area ICA. The light guide body LG1 is located between the emission light control area ICA of the liquid crystal panel PNL and the light sources EM2 and EM3. Since the light emitted from the light guide LG1 can be used to illuminate both the display area DA and the emission light control area ICA of the liquid crystal panel PNL, the boundary between the display area DA and the emission light control area ICA can be made inconspicuous and unobtrusive. Color display.

Or, in the emission light control area ICA, the liquid crystal panel PNL may have more than one adjustment electrode instead of a plurality of pixel electrodes PE. In this case, the shape and size of the adjustment electrode of the emitted light control area ICA may be different from the shape and size of the pixel electrode PE, or may be different from the shape and size of the control electrode of the incident light control area PCA.

According to the electronic device 100 of the ninth embodiment having the above-mentioned configuration, it is possible to obtain the electronic device 100 capable of performing photography well.

(Tenth Embodiment) Next, the tenth embodiment will be described. The electronic device 100 has the same configuration as the above-mentioned first embodiment except for the configuration described in the tenth embodiment. 49 is a plan view showing the light-shielding layer BM in the incident light control area PCA of the liquid crystal panel PNL of the electronic device 100 of the tenth embodiment.

As shown in FIG. 49, the incident light control area PCA has a plurality of circular incident light control areas TA, and a light shielding area LSA surrounding the plurality of incident light control areas TA. In the incident light control area PCA, the light-shielding layer BM is disposed in the light-shielding area LSA, and is not disposed in a plurality of incident light control areas TA. In this embodiment, the above-mentioned emitted light control area ICA is an area outside the light shielding area LSA. A plurality of incident light control areas TA are regularly arranged, for example, in the direction X and the direction Y in a matrix.

The first substrate SUB1 has a plurality of control electrodes located in each incident light control area TA. The liquid crystal panel PNL is configured to selectively transmit visible light from the outside in each incident light control area TA. Each incident light control area TA can function as a pinhole for adjusting the amount of light incident on the camera 1a. In the incident light control area PCA, a plurality of incident light control areas TA can function as compound eye pinholes.

For example, a plurality of control electrodes of the incident light control area PCA can be electrically connected to each other. In this case, it is possible to switch a plurality of incident light control areas TA into a transparent state or a non-transmitting state in batches by one control signal.

Or, the plurality of control electrodes of the incident light control area PCA can be electrically independent. In this case, each incident light control area TA can be individually switched to a transmission state or a non-transmission state.

By using compound eye pinholes, for example, the fingerprint FI shown in FIG. 50 can be photographed. Since it is not a photo shoot, it is only necessary to arrange the incident light control area TA by obtaining the image data of the fingerprint FI. As shown in Figure 50, you can open a gap in the captured image. That is, if the accuracy of personal authentication is maintained, it can become an image full of gaps.

In addition, as shown in FIG. 51, a plurality of incident light control areas TA may be arranged irregularly. A plurality of incident light control areas TA may be arranged in a matrix in the direction X and the direction Y. Thereby, the camera 1a can capture an image dependent on the arrangement of a plurality of incident light control areas TA. The electronic device 100 can associate the acquired image data with the arrangement patterns of a plurality of incident light control areas TA (the positions and numbers of the plurality of incident light control areas TA). For example, even if the memory of the electronic device 100 has image data, the arrangement pattern of the plurality of incident light control areas TA of the electronic device 100 does not correspond to the above-mentioned image data (not associated). Perform authentication. Thereby, for example, the electronic device 100 can improve the security. As described above, regarding the arrangement pattern of the plurality of incident light control areas TA, there may be individual differences among the plurality of electronic devices 100.

According to the electronic device 100 of the tenth embodiment having the above-mentioned configuration, it is possible to obtain the electronic device 100 capable of performing photography satisfactorily.

(Eleventh embodiment) Next, the eleventh embodiment will be described. The electronic device 100 has the same configuration as the above-mentioned first embodiment except for the configuration described in the eleventh embodiment. FIG. 52 is a plan view showing the arrangement of the liquid crystal panel PNL of the electronic device 100 and the arrangement of a plurality of cameras 1b in the eleventh embodiment.

As shown in FIG. 52, the electronic device 100 includes a liquid crystal panel PNL, a plurality of cameras 1b, and the like. The liquid crystal panel PNL does not have the incident light control area PCA. The plurality of cameras 1b overlap the display area DA, and are configured to allow infrared light from the outside to enter through the liquid crystal panel PNL. The camera 1b includes a light source EM2 configured to emit infrared light toward the liquid crystal panel PNL. The infrared light from the light source EM2 can illuminate the subject located on the side of the screen (the above-mentioned first surface S1).

Since the camera 1b is hidden in the display area DA of the liquid crystal panel PNL, the camera 1b cannot be observed by the user of the electronic device 100. It can reduce the user's sense of alertness when using the electronic device 100. In addition, by using infrared rays to photograph the subject with the camera 1b, it is possible to improve surveillance security. Furthermore, as a human interface, it can lower the threshold for hardware on the user side.

As shown in FIG. 53, the display area DA of the liquid crystal panel PNL includes an object area OA and one or more non-object areas NOA other than the object area. A plurality of pixels PX are located in the target area OA and the non-target area NOA. The plurality of pixels PX includes pixels of a plurality of colors. The plurality of pixels PX are regularly arranged in the display area DA. The arrangement of the pixels PX in the target area OA is the same as the arrangement of the pixels PX in the non-target area NOA. For example, the shape of the pixel electrode PE located in the target area OA is the same as the shape of the pixel electrode PE located in the non-target area NOA.

The camera 1b overlaps the non-target area NOA. The liquid crystal panel PNL can be configured to display an image in the target area OA, and display an image in a color other than white in the non-target area NOA. In this way, the camera 1b can be arranged in accordance with the design of the screen, and the user can further prevent the camera 1b from observing the camera 1b.

The liquid crystal panel PNL is configured to always display black in the non-target area NOA.

For example, a VA type or lateral electric field type liquid crystal panel uses a so-called normally black mode panel that displays black when no voltage is applied. This liquid crystal panel can always display black by forming the pixel electrode PE or the electrode of the control electrode structure RE in the non-target area NOA. Since the non-target area NOA transmits infrared light, it can receive infrared light with the camera 1b and can perform infrared photography. In the case that the non-target area NOA is always displayed in black, even if through holes are provided in the bottom plate BP, the light guide body LG1, and the reflective sheet RS, there is no adverse effect on the visibility of the image.

Thereby, it is possible to further prevent the user from observing the camera 1b. The electronic device 100 can collect information about the IR relationship (face authentication, vein authentication, etc.) in parallel with screen operations without the user's awareness. At this time, the electronic device 100 can also collect multiple types of authentication data at the same time.

In addition, by not disposing the pixel electrode PE in the non-target area NOA, but disposing the electrode of the control electrode structure RE, and arranging the camera 1a behind it, photography that requires an aperture effect can be realized.

According to the electronic device 100 of the eleventh embodiment configured as described above, it is possible to obtain the electronic device 100 that can perform photography satisfactorily. As in the eleventh embodiment, when the photography performed by the electronic device 100 is IR photography, the display panel is not limited to the liquid crystal panel PNL, and may be a display panel other than the liquid crystal panel PNL such as an organic EL display panel.

In addition, as shown in FIG. 9, the control electrode RL extending linearly may be referred to as a linear electrode, and the feeding wiring CL having the shape of a circular ring may be referred to as a ring-shaped wiring.

The above-mentioned insulating layer can be referred to as an insulating film.

The above-mentioned incident light control area can be referred to as an incident light restriction area.

The aforementioned non-display area NDA can be referred to as a peripheral area.
