Description

  The present disclosure relates to a display device having a lens member on the observation surface side of a display panel, a manufacturing method thereof, and an electronic apparatus including such a display device.

  In recent electronic device trends, miniaturization is further advanced. On the other hand, since there is a strong demand for an increase in the size of a display (display device), it is necessary to narrow the frame of the display device (display panel) itself in order to respond to the trend of downsizing in electronic devices. . However, frame widths of less than 1 mm have already been developed for display panels, and it is considered that there is a limit to physical narrowing of frames.

  Therefore, as one of the solutions to the above problem, a method has been proposed in which a lens member is arranged on the viewing surface side of the display panel to realize a pseudo narrow frame (see, for example, Patent Document 1).

JP 2010-15094 A

Thereby, the display light emitted from the frame area side in the effective display area is easily optically converted to the observer side by the lens function unit. That is, the display light whose optical path has been changed in the lens member (lens function unit) can easily reach the viewer as a whole, regardless of the emission source area in the effective display area.

  According to the display device, the manufacturing method thereof, and the electronic apparatus of the present disclosure, the outer line on the lens function unit side of the lens member is arranged outside the outer line of the frame region in the display panel. As a whole, it is possible to make the display light emitted from the laser beam easily reach the observer side. Therefore, it is possible to strengthen the pseudo narrowing effect by the lens function unit, and it is possible to achieve a narrower frame than the conventional one.

<Embodiment>
[Configuration of Liquid Crystal Display Device 1]
FIG. 1 schematically shows an external configuration of a display device (liquid crystal display device 1) according to an embodiment of the present disclosure in a perspective view. FIG. 2 shows a cross-sectional configuration example (an example of a cross-sectional configuration taken along the line II-II in FIG. 1) in the liquid crystal display device 1.

  As shown in FIG. 1, the liquid crystal display device 1 includes a backlight 10, a liquid crystal display panel 11, and a lens member 12 in this order from the back surface (back surface) side to the observation surface (display surface, front surface) side. Yes. The liquid crystal display device 1 also includes a resin layer 13 between the liquid crystal display panel 11 and the lens member 12 as shown in FIG.

  The backlight 10 is disposed on the back side of the liquid crystal display panel 11 and is a light source unit that emits light toward the liquid crystal display panel 11. Such a backlight 10 includes, for example, a light source such as a CCFL (Cold Cathode Fluorescent Lamp) or an LED (Light Emitting Diode) and various optical sheets ( Neither is shown).

(Liquid crystal display panel 11)
The liquid crystal display panel 11 is a display panel configured using a liquid crystal element. As shown in FIG. 1, the liquid crystal display panel 11 includes an effective display area 11a including a plurality of pixels (not shown) and an outer edge of the effective display area 11a. And a frame area (non-display area) 11b located on the (periphery). The liquid crystal display panel 11 also has a polarizing plate 111A (incident side polarizing plate), a substrate 110A, a liquid crystal layer 112a, and a light shield from the back side (backlight 10 side) to the observation surface side (lens member 12 side). A laminated structure including the film 112b, the substrate 110B, and the polarizing plate 111B (outgoing side polarizing plate) is formed (see FIG. 2).

  Each of the substrates 110A and 110B (a pair of substrates) is a light-transmitting substrate, and is configured using, for example, a glass substrate. The substrate 110A functions as a TFT substrate on which elements such as thin film transistors (TFTs) and wiring (both not shown) are formed. On the other hand, the substrate 110B functions as a CF substrate on which a color filter (CF) and a black matrix (BM) are formed.

  Each of the polarizing plates 111A and 111B is an optical element having a function of selectively transmitting a specific polarization component of incident light and absorbing another polarization component. These polarizing plates 111A and 111B are arranged so that their transmission axes are orthogonal to each other (crossed Nicols arrangement), or arranged so that their transmission axes are parallel to each other (parallel Nicols arrangement). .

  The liquid crystal layer 112a is inserted between the substrates 110A and 110B, and constitutes a liquid crystal element in the effective display area 11a. The light shielding film 112b is disposed in the frame region 11b. For example, various peripheral circuits (such as a drive circuit) are formed in the frame area 11b.

  The resin layer 13 functions as an adhesive layer for bonding the liquid crystal display panel 11 and the lens member 12 to each other, and is made of a resin material such as acrylic. Instead of the resin layer 13, an air layer (gap layer) may be provided between the liquid crystal display panel 11 and the lens member 12, and so on.

(Lens member 12)
The lens member 12 is disposed on the observation surface side of the liquid crystal display panel 11, and has a lens function part 12a in at least a part of the peripheral area (outer end area). Specifically, in the present embodiment, a lens function portion 12a that functions as a convex lens is formed on one end side of the four end sides of the lens member 12 (see FIG. 1). The lens member 12 is made of, for example, an optical glass material such as BK7, or a resin material such as acrylic or polycarbonate.

  Further, in the present embodiment, the outline of the lens member 12 on the lens function unit 12a side is arranged outside the outline of the frame region 11b in the liquid crystal display panel 11 (see FIG. 2). In other words, the outer end of the lens member 12 on the lens function unit 12a side is positioned outside the outer end (outer shape) of the entire liquid crystal display panel 11 (both the effective display area 11a and the frame area 11b). A lens member 12 is disposed.

[Method of Manufacturing Liquid Crystal Display Device 1]
The liquid crystal display device 1 can be manufactured as follows, for example. That is, first, the liquid crystal display panel 11 having the above-described effective display area 11a and frame area 11b is formed. Specifically, a substrate 110A as a TFT substrate and a substrate 110B as a CF substrate are formed using a glass substrate or the like, and then a liquid crystal layer 112a is formed by injecting liquid crystal between these substrates 110A and 110B. Form. Further, a light shielding film 112b is formed in the frame region 11b between the substrates 110A and 110B. In this way, the liquid crystal display panel 11 is formed.

  Next, the backlight 10 is disposed on the back side of the liquid crystal display panel 11, and the lens member 12 having the lens function unit 12 a is formed on the observation surface side of the liquid crystal display panel 11. Specifically, after such a lens member 12 is formed using, for example, acrylic or the like, the lens member 12 and the liquid crystal display panel 11 are bonded to each other through the resin layer 13. At this time, as described above, the outline of the lens member 12 on the lens function unit 12a side is arranged outside the outline of the frame region 11b of the liquid crystal display panel 11. Thus, the liquid crystal display device 1 shown in FIGS. 1 and 2 is completed.

[Operation and effect of liquid crystal display device 1]
(basic action)
In the liquid crystal display device 1, as shown in FIGS. 1 and 2, light (for example, illumination lights L10 and L20) emitted from the backlight 10 is displayed on the liquid crystal display according to control by a drive circuit (not shown). The panel 11 modulates each pixel. Thereby, display light L1 (for example, display light L11, L12) is emitted from the observation surface side of the liquid crystal display panel 11 and enters the lens member 12. And this display light L2 (L11, L12) is radiate | emitted outside from the lens member 12 as display light L2 (for example, display light L12, L22). In this way, video display is performed on the liquid crystal display device 1.

  At this time, as shown in FIG. 2, the display lights L11 and L21 emitted from the frame area 11b side of the effective display area 11a are optically converted by the lens function unit 12a in the lens member 12, and then displayed. L12 and L22 are emitted to the outside. Specifically, the display light L11 and L21 obliquely incident on the lens member 12 toward the outer side of the lens member 12 is refracted by the lens function unit 12a, whereby the thickness direction (vertical direction) of the liquid crystal display device 1 is obtained. ) And is emitted to the observer side. Thus, for the observer, since the display light appears to be emitted also in the frame region 11b, a pseudo narrowing of the frame is performed.

(Comparative example)
Here, FIG. 3 schematically shows a cross-sectional configuration of a display device (liquid crystal display device 101) according to a comparative example. Similar to the liquid crystal display device 1 of the present embodiment, the liquid crystal display device 101 of this comparative example includes the backlight 10, the liquid crystal display panel 11, the resin layer 13, and the lens member 12 from the back side toward the observation surface side. In this order.

  However, in the liquid crystal display device 101, unlike the liquid crystal display device 1, the lens member 12 is arranged so that the outline of the lens member 12 on the lens function unit 12 a side is positioned on the frame region 11 b in the liquid crystal display panel 11. Has been. In other words, the outer line on the lens function unit 12a side of the lens member 12 is arranged outside the outer line of the effective display area 11a in the liquid crystal display panel 11, but is arranged inside the outer line of the frame area 11b. Has been.

  For this reason, in the liquid crystal display device 101, a part of the display light obliquely incident on the lens member 12 toward the outer side of the lens member 12 (for example, the display light L21 shown in FIG. The light is refracted not on the lens function unit 12a but on the side surface of the lens member 12. Thereby, a part of the display light (for example, display light L21) emitted from the frame region 12b side in the effective display region 12a is not optically changed in the thickness direction (vertical direction) of the liquid crystal display device 1, and the liquid crystal display The light is emitted toward the outside of the device 101. In other words, the display light whose optical path has been changed in the lens member 12 (lens function unit 12a) is unlikely to reach the viewer side depending on the emission source area in the effective display area 11a. As a result, for the observer, a part of the frame area 11b (a part on the outer edge side) (here, the area 101b shown in FIG. 3) becomes an area that looks dark. That is, in the liquid crystal display device 101, the effect of pseudo narrowing the frame using the lens member 12 (lens function unit 12a) is insufficient.

(Operation of this embodiment)
On the other hand, in the liquid crystal display device 1 according to the present embodiment, as shown in FIG. 2, the outline of the lens member 12 on the lens function unit 12 a side is more than the outline of the frame region 11 b of the liquid crystal display panel 11. Arranged outside. In other words, the lens member 12 is arranged such that the outer end of the lens member 12 on the lens function unit 12a side is located outside the outer end of the entire liquid crystal display panel 11 (both the effective display area 11a and the frame area 11b). Is arranged.

  Thereby, the display light emitted from the frame area 11b side in the effective display area 11a (here, the display lights L11 and L21) is easily converted into an optical path by the lens function unit 12a. That is, unlike the comparative example described above, the display light whose optical path has been changed in the lens member 12 (lens function unit 12a) easily reaches the observer side as a whole regardless of the emission source area in the effective display area 11a. Become. For this reason, in this Embodiment, compared with the comparative example with which a part of display light (for example, display light L21) cannot reach | attain to an observer side, the pseudo | simulation narrowing frame effect | action by the lens function part 12a becomes strong. (A region that appears dark in the frame region 11b is less likely to exist).

  As described above, in the present embodiment, the outer line on the lens function unit 12a side of the lens member 12 is arranged outside the outer line of the frame region 11b in the display panel 11, and thus from the effective display region 11a. The emitted display light can easily reach the observer side as a whole. Therefore, the pseudo narrowing effect by the lens function part 12a can be strengthened, and the narrowing of the frame can be achieved as compared with the conventional case.

  Further, for example, when a plurality of liquid crystal display panels 11 are used in parallel in the liquid crystal display device 1, a joint (frame region between the liquid crystal display panels 11) between adjacent liquid crystal display panels 11 can be seen. In this case, it is possible to improve the image quality.

<Modification>
Subsequently, modified examples (modified examples 1 to 7) of the above-described embodiment will be described. In addition, the same code | symbol is attached | subjected about the component same as the said embodiment, and the description is abbreviate | omitted suitably.

[Modification 1]
FIG. 4 schematically illustrates a cross-sectional configuration example of a display device (liquid crystal display device 1A) according to the first modification. The liquid crystal display device 1A of this modification includes a backlight 10, a liquid crystal display panel 11A, a resin layer 13, a polarizing plate 111B, and a lens member 12 in this order from the back side to the observation surface side. In addition, the liquid crystal display panel 11A includes a polarizing plate 111A, a substrate 110A, a liquid crystal layer 11a, a light shielding layer 11b, and a substrate 110B from the back side toward the observation surface side.

  That is, in the liquid crystal display device 1A, in the liquid crystal display device 1 of the above embodiment, the output-side polarizing plate 111B is replaced with a resin layer instead of the liquid crystal display panel 11 (between the substrate 110B and the resin layer 13). 13 and the lens member 12, and the other configurations are the same. Specifically, here, the polarizing plate 111 </ b> B is attached (bonded) to the back side (the liquid crystal display panel 11 side) of the lens member 12.

  With this configuration, in the liquid crystal display device 1A of the present modification, the following effects can be obtained in addition to the effects in the above embodiment. That is, in this modification, the polarizing plate 111B is attached to the back side of the lens member 12, so that the outline of the polarizing plate 111B is positioned outside the outline of the liquid crystal display panel 11A. For this reason, in this modification, as compared with the above-described embodiment, it is possible to increase the tolerance of the positional deviation when the polarizing plate 111B is arranged, and the bonding tolerance of the polarizing plate 111B and further narrowing the frame are achieved. It becomes possible.

[Modification 2]
FIG. 5 schematically shows an external configuration of a display device (liquid crystal display device 1 </ b> B) according to Modification 2 in a perspective view. 6A and 6B show a cross-sectional configuration example (an example of a cross-sectional configuration taken along the line III-III in FIG. 5) in the liquid crystal display device 1B.

  As shown in FIG. 5, the liquid crystal display device 1B of the present modification is the same as the liquid crystal display panel 11 or the liquid crystal display panel 11A in the liquid crystal display device 1 of the above embodiment or the liquid crystal display device 1A of the first modification. Further, an exterior member (a casing, a frame) 14 is further provided on at least a part thereof. In addition, such an exterior member 14 is comprised, for example with metal materials, such as aluminum and stainless steel.

  Specifically, in the example of the liquid crystal display device 1B shown in FIG. 6A, the backlight 10, the liquid crystal display panel 11, the resin layer 13, and the lens member 12 are arranged from the back side toward the observation surface side. It is provided in order. Further, an exterior member 14 is provided (standing) on a part of the outer end region of the backlight 10. In other words, the exterior member 14 is physically connected (coupled) to the backlight 10. The lens member 12 is supported by the exterior member 14 in the outer end region of the lens function unit 12a. That is, the liquid crystal display device 1B shown in FIG. 6A corresponds to the liquid crystal display device 1 in which the exterior member 14 is further provided.

  In the example of the liquid crystal display device 1B shown in FIG. 6B, the backlight 10, the liquid crystal display panel 11A, the resin layer 13, the polarizing plate 111B, and the lens member 12 are arranged from the back side to the observation surface side. They are provided in this order. As in the example of FIG. 6A, the lens member 12 is supported by the exterior member 14 in the outer end region of the lens function unit 12a. That is, the liquid crystal display device 1B illustrated in FIG. 6B corresponds to the liquid crystal display device 1A in which the exterior member 14 is further provided.

  As described above, in the liquid crystal display device 1B of the present modification, the lens member 12 is supported by the exterior member 14 in the outer end region of the lens function unit 12a. In addition, the following effects can be obtained. That is, when the lens member 12 is arranged over the frame region 11b, it is difficult to secure a space for supporting the lens member 12 from the viewpoint of physical narrowing of the frame, so that the mechanical strength in the liquid crystal display device is reduced. There is a risk of it. Specifically, when the liquid crystal display panel 11 is bent, a problem of practical strength reduction is likely to occur. Therefore, by making the exterior member 14 provided originally also function as a support member for the lens member 12, a mechanical support in the liquid crystal display device 1B can be provided without providing a dedicated support member (without increasing the member cost). It is possible to improve the strength.

[Modification 3]
FIGS. 7A and 7B each schematically show a cross-sectional configuration example of a display device (liquid crystal display device 1C) according to the third modification. A liquid crystal display device 1C according to the present modification includes a liquid crystal lens in place of the lens member 12 made of optical glass or the like in the liquid crystal display device 1 according to the above embodiment or the liquid crystal display device 1A according to the first modification. Corresponding to the lens member 12 </ b> C configured by using, the other configuration is the same.

  Specifically, in the example of the liquid crystal display device 1C shown in FIG. 7A, the backlight 10, the liquid crystal display panel 11, the resin layer 13, and the lens member 12C are arranged from the back side toward the observation surface side. It is provided in order. That is, the liquid crystal display device 1C shown in FIG. 7A corresponds to the liquid crystal display device 1 in which the lens member 12C is provided instead of the lens member 12.

  On the other hand, in the example of the liquid crystal display device 1C shown in FIG. 7B, the backlight 10, the liquid crystal display panel 11A, the resin layer 13, the polarizing plate 111B, and the lens member 12C are arranged from the back side to the observation surface side. They are provided in this order. That is, the liquid crystal display device 1C shown in FIG. 7B corresponds to the liquid crystal display device 1A in which the lens member 12C is provided instead of the lens member 12.

(Lens member 12C)
The lens member 12C is configured by using a liquid crystal lens (for example, an ultraviolet curable liquid crystal lens described later) as described above, and the substrate 120A, the liquid crystal layer 121, and the substrate are arranged from the back side to the observation surface side. 120B in this order. In other words, the lens member 12C has a configuration in which the liquid crystal layer 121 is sandwiched between the pair of substrates 120A and 120B.

  Each of the substrates 120A and 120B is a light-transmitting substrate, and is made of, for example, a glass substrate. The liquid crystal layer 121 includes liquid crystal molecules aligned in a predetermined direction. For example, in the case of an ultraviolet curable liquid crystal lens, an ultraviolet curable polymer is provided together with the liquid crystal molecules.

  For example, in the case of an ultraviolet curable liquid crystal lens, the lens member 12C having such a configuration can be manufactured as follows. That is, first, a predetermined voltage is applied between electrodes (not shown) provided on the substrates 120A and 120B, respectively, so that the liquid crystal molecules in the liquid crystal layer 121 are aligned in a predetermined direction. Next, in this state, the polymer in the liquid crystal layer 121 is cured by irradiating the liquid crystal layer 121 with ultraviolet rays, and the orientation direction of each liquid crystal molecule is fixed (in a state where no voltage is applied between the electrodes). In addition, the alignment state of each liquid crystal molecule does not change). Thus, the lens member 12C using the ultraviolet curable liquid crystal lens is manufactured.

  Here, for example, in the lens member 12C shown on the left side in FIG. 8A, the liquid crystal molecules LC are gradually changed from the vertical alignment to the horizontal alignment from the outer end side to the inner direction of the lens member 12C. It has a structure. In the case of such an orientation structure, the lens member 12C functions as a convex lens as shown on the right side in FIG.

  On the other hand, in the lens member 12C shown on the left side in FIG. 8B, for example, the alignment structure in which the liquid crystal molecules LC gradually change from the horizontal alignment to the vertical alignment from the outer end side to the inner direction of the lens member 12C. It has become. In the case of such an alignment structure, the lens member 12C functions as a concave lens as shown on the right side in FIG.

  Also in the liquid crystal display device 1C of the present modification in which the lens member 12C having such a configuration is provided, the outer contour line on the lens function unit 12a side of the lens member 12C is outside the outer contour line of the frame region 11b in the display panel 11. Is arranged. Therefore, the same effect can be obtained by the same operation as that of the above-described embodiment or modification 1.

[Modification 4]
FIGS. 9A and 9B schematically show a cross-sectional configuration example of a display device (liquid crystal display device 1D) according to Modification 4. The liquid crystal display device 1D according to the present modification corresponds to the liquid crystal display device 1C according to the third modification, in which the exterior member 14 described in the second modification is further provided, and the other configurations are the same.

  Specifically, in the example of the liquid crystal display device 1D shown in FIG. 9A, the backlight 10, the liquid crystal display panel 11, the resin layer 13, and the lens member 12C are arranged from the back side toward the observation surface side. It is provided in order. The lens member 12C is supported by the exterior member 14 in the outer end region of the lens function unit 12a. That is, the liquid crystal display device 1D shown in FIG. 9A corresponds to the liquid crystal display device 1C shown in FIG. 7A in which the exterior member 14 is further provided.

  In the example of the liquid crystal display device 1D shown in FIG. 9B, the backlight 10, the liquid crystal display panel 11A, the resin layer 13, the polarizing plate 111B, and the lens member 12C are arranged from the back surface side to the observation surface side.

That is, the liquid crystal display device 1D illustrated in FIG. 9B corresponds to the liquid crystal display device 1C illustrated in FIG. 7B in which the exterior member 14 is further provided.

  In this way, in the liquid crystal display device 1D of the present modification, the lens member 12C is supported by the exterior member 14 in the outer end region of the lens function unit 12a. Similar effects can be obtained.

[Modification 5]
(Configuration of organic EL display device 2)
FIGS. 10A and 10B each schematically show a cross-sectional configuration example of a display device (organic EL display device 2) according to Modification 5. In this modification, an organic EL display device is used as an example of a display device instead of the liquid crystal display device described so far.
