Description

  One embodiment according to the present invention relates to an electro-optical device and an electronic apparatus.

  A plurality of different images (for example, a first image and a second image) are made different from each other by overlapping a light-shielding optical element having an opening on a surface of a display panel having a plurality of pixels at a certain distance. It is known that directivity can be displayed in a range (Patent Document 1). This utilizes the fact that different pixels are masked (light-shielded) according to the viewing angle by the optical element, in other words, light from different pixels is visually recognized through the opening according to the viewing angle.

  According to the electro-optical device capable of such directivity display, for example, the first image and the second image can be simultaneously viewed by different persons. Alternatively, if the light constituting the first image is incident on the left eye and the light constituting the second image is incident on the right eye, stereoscopic display can be performed. In this way, in order to change the direction of directional display, the distance between the pixel and the optical element may be adjusted.

  Here, as the display panel, a liquid crystal panel that performs display by modulating light from the lighting device or a self-luminous display panel that includes a light emitting element such as an organic EL (Electro Luminescence) panel can be used. In general, the light-shielding optical elements are arranged in such a manner that the light-shielding optical elements are formed on a glass substrate or the like to form a mask substrate, and the mask substrate is overlaid on a display panel.

Japanese Patent No. 3096613

  However, since the electro-optical device having such a configuration has a mask substrate in addition to the display panel, there are problems that the thickness is increased and the manufacturing process is complicated. In addition, in the above configuration, in order to adjust the distance between the pixel and the optical element, there is a problem that the thickness of the substrate constituting the display panel has to be changed.

  SUMMARY An advantage of some aspects of the invention is to solve at least a part of the problems described above, and the invention can be implemented as the following forms or application examples.

  Application Example 1 Light constituting the first image is emitted to the first range, and light constituting the second image is emitted to the second range including a range different from the first range. An electro-optical device, the first substrate, the second substrate disposed opposite to the first substrate, the first substrate and the second substrate, and A plurality of first pixels that emit light constituting the first image to the second substrate side; and the first image is disposed between the first substrate and the second substrate. A plurality of second pixels that emit light constituting the second substrate, the second substrate, the first pixel, and the second pixel; A first color filter including a first color element, a green first color element, and a blue first color element, the plurality of first pixels and the plurality of first color elements. Each pixel includes a red pixel that emits red light, a green pixel that emits green light, and a blue pixel that emits blue light. The red first color element includes light emitted from the first pixel of the red color into the first range and the second pixel of the red color from the second pixel. The light emitted to the second range is disposed in at least a part of a region through which the light passes, and the green first color element is transmitted from the first pixel of the green color to the first The light emitted to the range and the light emitted from the second pixel of the green color to the second range are both disposed in at least a part of the region, and the blue-based first Are emitted from the first pixel of blue color into the first range and from the second pixel of blue color into the second range. DOO are both electro-optical device is disposed on at least a part of the region that passes through.

  In the above configuration, light emitted from the red first pixel or the second pixel and incident on the green or blue first color element is absorbed by the color element and thus does not contribute to display. On the other hand, of the light emitted from the first pixel of the red color into the first range, the light incident on the first color element of the red color is transmitted through the color element and the first image is displayed. Constitute. Of the light emitted from the second pixel of the red color into the second range, the light incident on the first color element of the red color is transmitted through the color element to form the second image. Constitute. As described above, for the red pixel, a part of the first color elements (green and blue first color elements) included in the first color filter is directional to the light from the red pixel. Directivity display is performed by using a mask that gives Directivity display is performed on the blue and green pixels based on the same principle. As described above, the electro-optical device having the above-described configuration can display the first image composed of the light from the red, green, and blue first pixels in the first range. A second image composed of light from the green and blue second pixels can be displayed in the second range.

  Here, since the first color filter functions as a mask for directional display as described above, the electro-optical device having the above configuration has another light-shielding optical element (mask) for performing directional display. Do not need. For this reason, an electro-optical device capable of directivity display with fewer components can be configured. In addition, since the first color filter is formed between the first substrate and the second substrate, it is not necessary to separately attach a substrate on which a mask is formed to the outside of the first substrate. Thereby, the thickness of the electro-optical device can be reduced. Moreover, since the light which comprises the 1st image and the 2nd image has permeate | transmitted the 1st color element of the 1st color filter, color purity is compared with the light taken out directly from a pixel. high. For this reason, the electro-optical device having the above-described configuration can perform high-quality display with high color reproducibility.

  Application Example 2 In the electro-optical device, the first pixel and the second pixel include a pixel row in which the first pixel and the second pixel are alternately arranged in a first direction, the red pixel, The green pixel and the blue pixel are repeatedly arranged in this order along the first direction, the blue first color element, the green first color element, and the red first pixel. Are arranged repeatedly in this order along the first direction, and the arrangement pitch in the pixel row direction is approximately twice the arrangement pitch of the pixels in the pixel row direction. The electro-optical device, wherein the first color element arranged in a region overlapping with the pixel is the first color element having a different color from that of the one pixel.

  According to such a configuration, the first red pixel is arranged in one of the regions adjacent to the first red color element in the pixel row direction in front view, and the red first color element is arranged on the other side. A second pixel is arranged. Therefore, light emitted obliquely (in the first range) from the red first pixel toward the red first color element is transmitted through the red first color element. Construct a first image. In addition, light emitted obliquely (in the second range) from the red second pixel toward the red first color element passes through the red first color element. Construct a second image. Here, since the green or blue first color element is arranged outside the arrangement area of the red first color element, the red first pixel is emitted from the red system pixel. Light incident outside the element arrangement region is almost absorbed by the first green or blue color element and does not contribute to display. Since the diagonal directions from the red first pixel and the second pixel toward the red first color element are different from each other, the first range and the second range include different ranges. Directional display is performed.

  The same applies to the light from the blue pixel and the light from the green pixel. Therefore, the electro-optical device having the above configuration can display the first image composed of the light from the red, green, and blue first pixels in the first range. A second image composed of light from the second pixels of the system and the blue system can be displayed in the second range.

  In this specification, the front view refers to viewing from the normal direction of a surface on which pixels are arranged, or viewing from one point on the normal line of the surface.

  Application Example 3 In the electro-optical device described above, a red second color element, a green second color element, and a blue system are provided between the first color filter and the first substrate. A second color filter including the second color element, wherein the red pixel includes the red second color element, and the green pixel includes the green second color element. The electro-optical device includes the blue-based pixel including the blue-based second color element.

  According to such a configuration, each pixel emits light through the second color element, and the second color element emits the emitted light in a red color, a green color, or a blue color. Can be color. Here, since both the first color filter and the second color filter are disposed between the first substrate and the second substrate, the first color filter and the second color filter The interval can be easily reduced. That is, the distance between the pixel and the first color filter that functions as a mask that gives directivity to light from the pixel can be easily reduced. Thereby, the 1st range in which the light which comprises a 1st image is inject | emitted, and the 2nd range in which the light which comprises a 2nd image is inject | emitted can be made greatly different.

  Application Example 4 In the above electro-optical device, a light-transmitting resin is disposed between the first color filter and the second color filter.

  According to such a configuration, the interval between the first color filter and the second color filter can be easily set to a desired value.

Driven by a second polarizing plate disposed on the second substrate side of the pixel, a pair of electrodes provided in the first pixel and the second pixel, and an electric field generated between the pair of electrodes And an electro-optical device.

  According to such a configuration, the first pixel and the second pixel convert the polarization state of the light incident from the first polarizing plate by the liquid crystal and emit it. This light emitted from the first pixel and the second pixel can be transmitted through the second polarizing plate with a transmittance corresponding to the polarization state to form a first image or a second image.

  Application Example 6 The electro-optical device includes a pair of electrodes provided in the first pixel and the second pixel, and an organic light emitting layer disposed between the pair of electrodes. Electro-optic device.

  According to such a configuration, the first pixel and the second pixel can emit light emitted from the organic light emitting layer.

  Application Example 7 In the electro-optical device, the first pixel and the second pixel have a plurality of pixel columns in which the first pixel and the second pixel are alternately arranged in a second direction intersecting the pixel row. Optical device.

  According to such a configuration, the first pixel and the second pixel are arranged in a checkered pattern. At this time, the arrangement of the first color elements in the first color filter is a so-called delta arrangement. According to such an arrangement, it is possible to suppress a decrease in the resolution of the first image and the second image.

(First embodiment)
1A and 1B are diagrams illustrating a configuration of a liquid crystal device 1 as an electro-optical device according to a first embodiment. FIG. 1A is a perspective view, and FIG. 1B is a cross-sectional view taken along line AA in FIG. It is.

The element substrate 10 is larger than the color filter substrate 30, and a part thereof protrudes from the color filter substrate 30. A driver IC 55 that supplies a drive signal and the like for operating the liquid crystal device 1 is mounted on the surface of the element substrate 10 that protrudes from the color filter substrate 30 on the observation side. The liquid crystal device 1 performs display in the display area 9 by modulating light from a backlight or the like (not shown) and transmitting it to the observation side.

  As shown in FIG. 1B, the color filter substrate 30 is bonded to the observation side of the element substrate 10 via a sealant 29 arranged in a frame shape that substantially matches the contour shape of the color filter substrate 30. Yes. Liquid crystal 50 is sealed in a space surrounded by the element substrate 10, the color filter substrate 30, and the sealing agent 29.

On the back side of the glass substrate 31, a color filter 33 as a first color filter, a resin layer 35 made of a light-transmitting resin, and a color filter 43 as a second color filter are laminated in this order.

  2A and 2B are plan views of the liquid crystal device 1 in the display area 9, where FIG. 2A is a plan view showing the configuration of the color filter 43 and FIG. 2B is a plan view showing the configuration of the color filter 33. It is. This figure is a view of the liquid crystal device 1 as viewed from the observation side, more specifically, from the normal direction of the color filter substrate 30. FIGS. 2A and 2B show the same region overlapped when viewed from the observation side, and the liquid crystal device 1 includes the color filter 43 of FIG. 2A and FIG. 2B. The color filter 33 is superposed.

  As shown in FIG. 2A, the color filter 43 includes rectangular color elements 42r, 42g, and 42b arranged in a matrix over a plurality of rows and a plurality of columns (hereinafter, when the corresponding colors are not distinguished from each other). Simply has “color element 42”. The color elements 42r, 42g, and 42b are members that transmit red light, green light, and blue light, and absorb light of other colors. Here, the red color, the green color, and the blue color are, for example, red, green, and blue. The color element 42r corresponds to a red second color element, the color element 42g corresponds to a green second color element, and the color element 42b corresponds to a blue second color element. . A light shielding layer 46 made of a black resin is disposed in a grid-like region that partitions the color elements 42r, 42g, and 42b. The color filter 43 includes color elements 42r, 42g, and 42b and a light shielding layer 46.

  FIG. 2A also shows a planar arrangement of pixels included in the liquid crystal device 1. The liquid crystal device 1 includes rectangular pixels 4r, 4g, and 4b (hereinafter, simply referred to as “pixel 4” when the corresponding colors are not distinguished) arranged in a matrix over a plurality of rows and columns. is doing. Color elements 42r, 42g, and 42b are arranged in the pixels 4r, 4g, and 4b, respectively. Since the pixels 4r, 4g, and 4b emit light through these color elements 42, they emit red light, green light, and blue light to the observation side, respectively. Can do. The pixels 4r, 4g, and 4b correspond to a red pixel, a green pixel, and a blue pixel, respectively.

  The pixels 4r, 4g, and 4b are repeatedly arranged in this order along the first direction to form the pixel row 5. Accordingly, the color elements 42r, 42g, and 42b are also repeatedly arranged in this order along the extending direction of the pixel row 5. In the second direction intersecting with the pixel row 5, the pixels 4 are arranged so that the pixels 4 corresponding to the same color are arranged in a line in a stripe shape, thereby forming a pixel column 6. Therefore, the color elements 42r, 42g, and 42b are also arranged so that the color elements 42 corresponding to the same color are arranged in a stripe shape in the extending direction of the pixel column 6. In the present embodiment, the extending direction of the pixel column 6 is orthogonal to the extending direction of the pixel row 5. In this specification, the extending direction of the pixel row 5 is defined as the X axis, and the extending direction of the pixel column 6 is defined as the Y axis. The normal direction of the XY plane is defined as the Z axis. The first direction is a direction along the positive direction of the X axis, and the second direction is a direction along the positive direction of the Y axis.

  The light emitted from each pixel 4 constitutes either the first image or the second image. The pixel 4 that emits light constituting the first image is also called a pixel L, and the pixel 4 that emits light constituting the second image is also called a pixel R. Pixels L and R correspond to a first pixel and a second pixel, respectively. All of the pixels 4r, 4g, and 4b described above correspond to either the pixel L or the pixel R. Further, the pixel group composed of the plurality of pixels L and the pixel group composed of the plurality of pixels R all include the pixels 4r, 4g, and 4b. The pixels L and R are alternately and repeatedly arranged along the pixel row 5, and are arranged in stripes along the pixel column 6 so that the same species are arranged in a line. Hereinafter, the pixel 4 corresponding to the first pixel (pixel L) is denoted as pixel 4 (L), and the pixel 4 corresponding to the second pixel (pixel R) is denoted as pixel 4 (R). For example, the blue pixel 4b corresponding to the first pixel is represented as a pixel 4b (L).

  As shown in FIG. 2B, the color filter 33 has stripe-shaped color elements 32r, 32g, and 32b along the Y direction (hereinafter, in the case where the corresponding colors are not distinguished, simply “ Also called “color element 32”). The color elements 32r, 32g, and 32b are members that transmit red light, green light, and blue light, respectively, and absorb light of other colors. The color element 32r corresponds to a red first color element, the color element 32g corresponds to a green first color element, and the color element 32b corresponds to a blue first color element. . Here, the color of the light transmitted through the color elements 32r, 32g, and 32b does not need to exactly match the color of the light transmitted through the color elements 42r, 42g, and 42b, and may be a similar color.

  The color elements 32b, 32g, and 32r are repeatedly arranged in this order along the first direction (that is, the positive direction of the X axis). Here, the repetition order of the colors of the color elements 32 is opposite to the repetition order of the colors of the pixels 4 (that is, the repetition order of the colors of the color elements 42). The arrangement pitch of the color elements 32 in the pixel row 5 direction is approximately twice the arrangement pitch of the pixels 4 in the pixel row 5 direction. The color element 32 arranged in a region overlapping the certain pixel 4 in the front view is a color element 32 having a different color from that of the pixel 4. That is, the color element 32g or the color element 32b is arranged in the area overlapping the pixel 4r when viewed from the front, the color element 32b or the color element 32r is arranged in the area overlapping the pixel 4g, and the color element in the area overlapping the pixel 4b. 32r or color element 32g is arranged.

  Here, the “front view” means viewing from the normal direction of the surface on which the pixels 4 are arranged (that is, the normal direction of the color filter substrate 30). More specifically, the front view means that each point on the liquid crystal device 1 is viewed from the normal direction as shown in FIG. 17A, and that the liquid crystal device 1 is seen as shown in FIG. This is a concept that includes any of the following points: viewing each point from one point on the normal line. Accordingly, in the case of “element m and element n overlap in front view”, the method of FIG. 17A means that the position when element m and element n are projected onto the XY plane is the same. In the method (b), the element n is located inside a virtual solid having the element m as a bottom surface and an observation point as a vertex. “Front view” in the present embodiment refers to a front view of the method of FIG.

  FIG. 3 is a cross-sectional view when the liquid crystal device 1 is cut along the XZ plane at a position including the pixels 4. FIG. 3 is also an enlarged view of a part of FIG. The sectional structure of the liquid crystal device 1 will be described with reference to this drawing.

  A circuit element layer 12 is formed on the observation side of the glass substrate 11 included in the element substrate 10. The circuit element layer 12 includes a TFT (Thin Film Transistor) element as a switching element used for driving the liquid crystal 50, a scanning line for applying a drive signal to the TFT element, a data line, a capacitor element, and the like. On the observation side of the circuit element layer 12, a pixel electrode 14 made of light-transmitting ITO (Indium Tin Oxide) is formed for each pixel 4. The pixel electrode 14 is formed in a rectangular shape that is substantially the same shape as the pixel 4 in FIG. The pixel electrode 14 is electrically connected to the TFT element in the circuit element layer 12. An alignment film 18 made of polyimide or the like is formed on the observation side of the pixel electrode 14. The alignment film 18 is rubbed and has a function of aligning the liquid crystal 50 along the rubbing direction. The element substrate 10 is configured by elements from the glass substrate 11 to the alignment film 18.

  As described above, the color filter 33, the resin layer 35, and the color filter 43 are stacked in this order on the back side of the glass substrate 31 included in the color filter substrate 30. Among these, the resin layer 35 can be a laminate film having a thickness of about 50 nm to 100 nm, for example. A common electrode 47 made of ITO is formed on substantially the entire back surface of the color filter 43. The common electrode 47 and the pixel electrode 14 are a pair of electrodes, and the liquid crystal 50 is driven by an electric field generated between the pair of electrodes. An alignment film 48 made of polyimide or the like is formed on the back side of the common electrode 47. The alignment film 48 has been rubbed and has a function of aligning the liquid crystal 50 along the rubbing direction. The color filter substrate 30 is configured by elements from the glass substrate 31 to the alignment film 48.

  A liquid crystal 50 is disposed between the element substrate 10 and the color filter substrate 30, that is, between the alignment film 18 and the alignment film 48. The rubbing directions of the alignment films 18 and 48 are orthogonal, and the liquid crystal 50 is in the TN mode. The transmission axis of the polarizing plate 51 disposed on the back side of the element substrate 10 is parallel to the rubbing direction of the alignment film 18. Further, the transmission axis of the polarizing plate 53 disposed on the observation side of the color filter substrate 30 is parallel to the rubbing direction of the alignment film 48. Therefore, the transmission axes of the polarizing plates 51 and 53 are orthogonal in a plan view.

  When an off voltage is applied between the pixel electrode 14 and the common electrode 47 or when no voltage is applied, the liquid crystal 50 is twisted by 90 degrees. At this time, the linearly polarized light transmitted through the polarizing plate 51 is converted into linearly polarized light parallel to the transmission axis of the polarizing plate 53 due to the optical rotation of the liquid crystal 50 and is transmitted through the polarizing plate 53. Thereby, white display is performed.

  When an on voltage is applied between the pixel electrode 14 and the common electrode 47, the liquid crystal 50 is aligned substantially perpendicular to the alignment films 18 and 48. At this time, the linearly polarized light transmitted through the polarizing plate 51 is incident on the polarizing plate 53 without being given a phase difference depending on the liquid crystal 50 and is absorbed by the polarizing plate 53. Thereby, black display is performed.

  The liquid crystal device 1 performs such white display, black display, or halftone display of these for each pixel 4 to display the display area 9 as a set.

  The pixel 4 (pixels L and R) described above includes the pixel electrode 14, the liquid crystal 50, the common electrode 47, and the color element 42. The area occupied by each pixel 4 is a rectangular area (FIG. 2A) surrounded by the light-shielding layer 46 in a plan view. In the cross-sectional view of FIG. It is an area to include. Alternatively, the pixel electrode 14 to the color element 42 may be defined as the pixel 4. Therefore, the pixel 4 (pixels L and R) is disposed between the glass substrates 11 and 31. The color filter 33 is disposed between the pixel 4 (pixels L and R) and the glass substrate 31. The color filter 43 is disposed between the color filter 33 and the glass substrate 11. The polarizing plate 51 is disposed on the glass substrate 11 side of the pixel 4 (pixels L and R), and the polarizing plate 53 is disposed on the glass substrate 31 side of the pixel 4 (pixels L and R).

  The pixel 4 emits light incident from the back side to the observation side via the color element 42. Therefore, the observation side surface of the color element 42 becomes the light emission surface of the pixel 4. The color filter 33 is disposed on the light emission side of the pixel 4, and the light emitted from the pixel 4 is incident on any color element 32 included in the color filter 33.

  FIG. 4 is a schematic diagram showing the principle of directivity display by the pixel 4b among the three color pixels 4. As shown in FIG. In this figure, elements other than the pixel 4 and the color filter 33 in the liquid crystal device 1 are omitted.

  The light of blue color emitted from the pixel 4 b (L) enters the color filter 33. Among these, the light incident on the color element 32b passes through the color element 32b and is emitted to the first range 3L. The range of the optical path of the light emitted to the first range 3L is indicated by a two-dot chain line in FIG. 4 (the same applies to the following drawings). On the other hand, the light incident on the other color elements 32 (color elements 32r and 32g) is absorbed by the color elements 32, and therefore hardly transmits to the observation side of the color filter 33.

  Similarly, out of the blue light emitted from the pixel 4b (R), the light incident on the color element 32b is transmitted through the color element 32b and emitted to the second range 3R. The range of the optical path of the light emitted to the second range 3R is indicated by a solid line in FIG. 4 (the same applies to the following drawings). On the other hand, light incident on the other color elements 32 (color elements 32 r and 32 g) is absorbed by the color elements 32 and hardly transmitted to the observation side of the color filter 33.

  In this way, for blue-colored light emitted from the pixel 4b, the color elements 32r and 32g function as light shielding members, so that the range in which the emitted light travels is limited. Since the positions of the pixel 4b (L) and the pixel 4b (R) are different from each other when viewed from the color element 32b, the light emitted from the pixel 4b (L) and the pixel 4b (R) through the color element 32b is emitted. The traveling directions of are different from each other. That is, the light from the pixel 4b (L) is emitted to the first range 3L, and the light from the pixel 4b (R) is emitted to the second range 3R including a range different from the first range 3L. . In this way, the directional display by the combination of the pixel 4b (L), the pixel 4b (R) and the color filter 33 is performed.

  From another point of view, the blue-based color element 32b is configured so that the light emitted from the pixel 4b (L) into the first range 3L and the light emitted from the pixel 4b (R) into the second range 3R are either Is also disposed in at least a part of the region through which it passes. That is, the first range 3L and the second range 3R to which the light from the pixel 4b (L) and the pixel 4b (R) should reach are set in advance, and the color element 32b is arranged in the region that satisfies the above conditions. By doing so, a desired directivity display can be realized.

  The principle of directional display by the pixel 4b has been described above, but the principle of directional display by the pixel 4g and the pixel 4r is the same as this. FIG. 5 is a schematic diagram showing the principle of directional display by the pixel 4g. For the green light emitted from the pixel 4g, the color elements 32b and 32r function as a light shielding member, so that the light emitted from the pixel 4g transmits only the color element 32g. As a result of the light traveling range being limited in this way, the light from the pixel 4g (L) is emitted to the first range 3L, and the light from the pixel 4g (R) is different from the first range 3L. It is injected into the second range 3R including the range. In this way, directional display by the combination of the pixel 4g (L), the pixel 4g (R) and the color filter 33 is performed.

  From another point of view, the green color element 32g is configured so that light emitted from the pixel 4g (L) to the first range 3L and light emitted from the pixel 4g (R) to the second range 3R are any. Is also disposed in at least a part of the region through which it passes. That is, the first range 3L and the second range 3R to which the light from the pixel 4g (L) and the pixel 4g (R) should reach are set in advance, and the color element 32g is arranged in an area that satisfies the above conditions. By doing so, a desired directivity display can be realized.

  FIG. 6 is a schematic diagram showing the principle of directional display by the pixel 4r. For the red light emitted from the pixel 4r, the color elements 32g and 32b function as a light shielding member, so that the light emitted from the pixel 4r transmits only the color element 32r. As a result of the light traveling range being restricted in this way, the light from the pixel 4r (L) is emitted to the first range 3L, and the light from the pixel 4r (R) is different from the first range 3L. It is injected into the second range 3R including the range. In this way, the directional display by the combination of the pixel 4r (L), the pixel 4r (R) and the color filter 33 is performed.

  In another aspect, the red-based color element 32r is configured so that either the light emitted from the pixel 4r (L) into the first range 3L or the light emitted from the pixel 4r (R) into the second range 3R is selected. Is also disposed in at least a part of the region through which it passes. In other words, the first range 3L and the second range 3R to which the light from the pixel 4r (L) and the pixel 4r (R) should reach are set in advance, and the color element 32r is arranged in an area that satisfies the above conditions. By doing so, a desired directivity display can be realized.

  As described above, as a result of the light from the pixels 4r, 4g, and 4b being emitted with directivity, the liquid crystal device 1 emits the light constituting the first image into the first range 3L, and the second The light constituting the image is emitted to the second range 3R including a range different from the first range 3L. That is, the first image and the second image can be displayed in different directions. Here, both the first image and the second image can be color images. Further, since the light from the pixels 4r, 4g, and 4b is emitted from the liquid crystal device 1 through the color elements 32r, 32g, and 32b, respectively, the light is directly extracted from the pixel 4 without passing through the color elements 32. In comparison, the color purity can be increased.

  FIG. 7 is a schematic diagram illustrating a typical optical path of light that contributes to display among the light emitted from the pixels 4 of three colors. The viewpoint VL in FIG. 7 is a point located substantially at the center of the first range 3L in FIGS. 4 to 6, and the viewpoint VR is a point located substantially at the center of the second range 3R. According to this figure, the display by the pixels 4r (L), 4g (L), and 4b (L) is visually recognized from the viewpoint VL, and the pixels 4r (R), 4g (R), and 4b (R) are viewed from the viewpoint VR. It can be seen that the display by is visually recognized. If different persons are positioned at the viewpoints VL and VR, different images can be visually recognized by these persons. Further, if the distance between the viewpoint VL and the viewpoint VR is reduced and the left eye and the right eye are positioned at the respective viewpoints, the stereoscopic image can be visually recognized. Here, in order to reduce the distance between the viewpoint VL and the viewpoint VR, the distance in the Z direction between the pixel 4 and the color filter 33 may be increased. In order to adjust the distance between the pixel 4 and the color filter 33, for example, the thickness of the resin layer 35 may be changed.

  In FIG. 7, a viewpoint VC positioned between the viewpoints VL and VR corresponds to the viewpoint in the above-described “front view”. When viewed from the viewpoint VC (front view), as described above, the color element 32 arranged in the area overlapping the certain pixel 4 is a color element 32 having a different color from that of the pixel 4. That is, a color element 32 having a color different from that of the pixel 4 is located on a line segment connecting the viewpoint VC and the pixel 4. Thereby, it is difficult to visually recognize the display by the pixels L and R at the viewpoint VC, and the directional display by the pixel L or the pixel R can be visually recognized by bringing the observation position close to the viewpoint VL or the viewpoint VR. . The arrangement pitch of the color elements 32 in the X direction is smaller than twice the arrangement pitch of the pixels 4 so as to satisfy the above condition in front view.

  In FIG. 7, the viewpoints VL and VR are set in the vicinity of the color filter 33 for convenience of explanation. However, in practice, the distance between the viewpoints VL and VR and the color filter 33 is, for example, 1000 times or more with respect to the arrangement pitch of the color elements 32, and becomes considerably large. Therefore, when the pixel 4 and the color filter 33 are observed microscopically, as shown in FIG. 8, the representative optical paths of the light that contributes to display out of the light emitted from the pixel 4 are substantially parallel to each other. It becomes.

  In FIG. 8, the position of the viewpoint when viewed from the front (viewpoint VC in FIG. 7) is approximated to infinity with respect to the color filter 33. Therefore, in this figure, the relative positional relationship of the components in plan view as viewed from the positive direction of the Z axis is the relative positional relationship of the components in front view as it is. As can be seen from this figure, the pixel 4r (L) is arranged in one of the regions adjacent to the red color element 32r in the X direction in the front view, and the pixel 4r (R) is arranged in the other. Yes. Light emitted obliquely from the pixel 4r (L) toward the color element 32r (in the first range 3L) passes through the color element 32r to form a first image. In addition, light emitted obliquely from the pixel 4r (R) toward the color element 32r (in the second range 3R) passes through the color element 32r to form a second image. Since the oblique directions from the pixels 4r (L) and 4r (R) toward the color element 32r are different from each other, the first range 3L and the second range 3R include different ranges, and directivity display is performed. Is called. Also, it can be seen from this figure that the arrangement pitch of the color elements 32 in the X direction is approximately twice the arrangement pitch of the pixels 4 in the X direction. Further, it can be seen that a color element 32 having a color different from that of the pixel 4 is located in a region overlapping the pixel 4 in a front view.

  As described above, according to the liquid crystal device 1 of the present embodiment, the first image and the second image can be directionally displayed in different ranges. At this time, as described in FIGS. 4 to 6, since the color filter 33 functions as a mask for directional display, the liquid crystal device 1 has another light-shielding optical element (in order to perform directional display). Does not require a mask. For this reason, the liquid crystal device 1 capable of directional display can be configured with fewer components. Further, since the color filter 33 that functions as a mask is formed between the glass substrate 11 and the glass substrate 31, it is not necessary to separately attach a substrate on which the mask is formed to the outside of the glass substrate 31. Thereby, the thickness of the liquid crystal device 1 can be reduced.

  In the liquid crystal device 1 having such a configuration, for example, after the color filters 33 and 43 are formed on the glass substrate 31 and the color filter substrate 30 is manufactured, the element substrate 10 and the color filter substrate are formed similarly to the conventional liquid crystal device. 30 can be manufactured by the process of bonding together. That is, an additional step for adding a mask for directivity display after the substrates are bonded is not necessary. Here, the conventional liquid crystal device refers to a liquid crystal device provided with a single color filter on the color filter substrate 30.

  The color filters 33 and 43 are both disposed between the glass substrate 11 and the glass substrate 31, and there is no glass substrate between the color filter 33 and the color filter 43. For this reason, the space | interval of the color filter 33 and the color filter 43 can be made small easily. That is, it is not necessary to etch the glass substrate in order to reduce the distance between the pixel 4 and the color filter 33 that functions as a mask that gives directivity to the light from the pixel 4, and the distance can be easily reduced. . Thereby, the first range 3L in which light constituting the first image is emitted and the second range 3R in which light constituting the second image is emitted can be greatly different. The distance between the color filter 33 and the color filter 43 can be easily adjusted, for example, by changing the thickness of the resin layer 35.

  In addition, since the light constituting the first image and the second image are both transmitted through the color element 32 of the color filter 33, the color purity is higher than that of the light extracted directly from the pixels 4. For this reason, the liquid crystal device 1 can perform high-quality display with high color reproducibility.

(Second Embodiment)
Next, the second embodiment will be described. The liquid crystal device 1 of the second embodiment is different from the first embodiment in the arrangement of the pixels L and R and the arrangement of the color elements 32 and 42, and the other points are the same as in the first embodiment.

  FIG. 9 is a plan view of the liquid crystal device 1 according to the second embodiment. FIG. 9A is a plan view showing the configuration of the color filter 43. FIG. 9B is a plan view showing the configuration of the color filter 33. FIG. FIG.

  As shown in FIG. 9A, in the present embodiment, the pixels L and R are alternately arranged in the pixel row 5 direction (X direction) and the second direction (Y (Direction) are also arranged alternately. Accordingly, the pixels L and R are alternately arranged along the Y direction to form a pixel column 6. Therefore, the pixels L and R are arranged in a check pattern or a mosaic pattern so as to form a checkered pattern.

  Further, the positional relationship between the color element 32 and the pixels L and R is the same as that of the first embodiment. For example, the pixel is located in a region adjacent to the red color element 32r in the positive direction of the X axis when viewed from the front. 4r (L) is arranged, and a pixel 4r (R) is arranged in a region adjacent in the negative direction. The same applies to the green color element 32g and the blue color element 32b. Here, since the pixels L and R are arranged in a checkered pattern as described above, the color elements 32 of the color filter substrate 30 have a delta arrangement as shown in the arrangement diagram 9B. More specifically, in any row of the color elements 32 (arrangement of the color elements 32 along the X direction), the color elements 32b, 32g, and 32r are repeatedly arranged along the positive direction of the X axis. Between the matching rows, the arrangement pitch of the minimum repeating unit of the color elements 32 is shifted by a half pitch. Here, the repetitive minimum unit of the color element 32 refers to a block composed of three adjacent color elements 32b, 32g, and 32r. In other words, the color elements 32 of the same color are arranged shifted in the X direction by 1.5 times the width of the color elements 32 in adjacent rows. The width of each color element 32 in the X direction is approximately twice the width of the pixel 4 in the X direction.

  According to such an arrangement, each of the color elements 32 includes the light emitted from the pixel L having the same color as the color element 32 to the first range 3L and the second pixel from the pixel R having the same color. It is disposed in at least a part of a region through which all the light emitted to the range 3R passes. Further, a color element 32 having a color different from that of the pixel 4 is arranged in a region overlapping the pixel 4 in front view. Therefore, directivity display can be performed according to the same principle as in the first embodiment.

  FIGS. 10A and 10B are schematic diagrams showing optical paths from the respective pixels 4 at the positions of the BB line and the CC line in FIGS. 9A and 9B. As shown in this figure, the positions of the pixels L and R are inverted for each pixel row 5. As a result, in both of FIGS. 10A and 10B, the first image by the pixel L is visually recognized at the viewpoint VL. Then, the second image by the pixel R is visually recognized at the viewpoint VR.

  By arranging the pixels L and R so as to form a checkered pattern as shown in FIG. 9A, compared to the case where the pixels L and R are arranged in a stripe pattern (FIG. 2A), The resolution of the first image and the second image can be improved. This is because the minimum relative distance (for example, the distance between a certain pixel 4r (L) and the nearest pixel 4r (L)) between the two pixels 4 having the same effect on the corresponding color and the image to be displayed becomes close. Because.

(Third embodiment)
Subsequently, a third embodiment will be described. The third embodiment relates to an organic EL device 2 as an electro-optical device. In the following description, differences from the liquid crystal device 1 according to the first embodiment will be described. The other points are the same as in the first embodiment.

  11A and 11B are diagrams illustrating a configuration of an organic EL device 2 as an electro-optical device according to the third embodiment, in which FIG. 11A is a perspective view and FIG. 11B is a cross-sectional view taken along line DD in FIG. FIG. The organic EL device 2 includes an element substrate 20 and a color filter substrate 30 disposed to face the observation side of the element substrate 20. The element substrate 20 is larger than the color filter substrate 30, and a part thereof protrudes from the color filter substrate 30. A driver IC 55 that supplies a drive signal and the like for operating the organic EL device 2 is mounted on the surface of the element substrate 20 that protrudes from the color filter substrate 30 on the observation side. The organic EL device 2 performs display in the display area 9 by light from the light emitting element 28 (FIG. 11B) included in the element substrate 20.

  As shown in FIG. 11B, the color filter substrate 30 is observed on the element substrate 20 via a sealing agent 29 arranged in a frame shape substantially matching the contour shape of the color filter substrate 30 and an adhesive layer 34. It is stuck to the side. The sealant 29 may include a spacer for keeping the distance between the element substrate 20 and the color filter substrate 30 constant. Alternatively, the element substrate 20 and the color filter substrate 30 may be bonded together using only the adhesive layer 34 or only the sealant 29.

  The element substrate 20 is configured with a glass substrate 21 as a first substrate as a base. A plurality of light emitting elements 28 and the like are formed on the observation side of the glass substrate 21. The light emitting element 28 is hermetically sealed with a color filter substrate 30, a sealing agent 29, and an adhesive layer 34.

  The color filter substrate 30 is configured with a glass substrate 31 as a second substrate as a base. A color filter 33 as a first color filter is formed on the back side of the glass substrate 31.

  FIG. 12A is a plan view of the element substrate 20 in the display area 9, and FIG. 12B is a plan view showing the configuration of the color filter 33 in the display area 9. FIGS. 12A and 12B show the same region overlapped when viewed from the observation side. The organic EL device 2 is formed on the element substrate 20 of FIG. The color filter substrate 30 having the color filter 33 of FIG.

  As shown in FIG. 12A, the element substrate 20 has rectangular pixels 4r, 4g, and 4b arranged in a matrix over a plurality of rows and a plurality of columns. Each of the pixels 4r, 4g, and 4b includes a light emitting element 28 (FIG. 11B). The pixels 4r, 4g, and 4b emit light of a red color, a green color, and a blue color by the function of the light emitting element 28, respectively. The pixels 4r, 4g, and 4b correspond to a red pixel, a green pixel, and a blue pixel, respectively. The arrangement of the pixels 4r, 4g, 4b is the same as that in the first embodiment.

  Each pixel 4 corresponds to one of a pixel L that emits light constituting the first image and a pixel R that emits light constituting the second image. The arrangement of the pixels L and R is the same as in the first embodiment.

  As shown in FIG. 12B, the configuration of the color filter 33 including the color elements 32r, 32g, and 32b is the same as that of the first embodiment. Therefore, the color element 32 arranged in a region overlapping with a certain pixel 4 in front view is a color element 32 having a different color from that of the pixel 4.

  FIG. 13 is a cross-sectional view when the organic EL device 2 is cut along the XZ plane at a position including the pixel 4. FIG. 13 is also an enlarged view of a part of FIG. The configuration of the light emitting element 28 formed on the element substrate 20 will be described with reference to FIG.

  A circuit element layer 22 is formed on the observation side of the glass substrate 21 included in the element substrate 20. The circuit element layer 22 includes a TFT element for driving the light emitting element 28, a scanning line for applying a driving signal to the TFT element, a data line, a capacitor element, and the like. On the observation side of the circuit element layer 22, a pixel electrode 24 as an anode made of light-transmitting ITO is formed. The pixel electrode 24 is formed in a rectangular shape that is substantially the same shape as the pixel 4 in FIG. A reflective film (not shown) is formed on the back side of the pixel electrode 24. A bank 23 made of resin or the like is formed around the pixel electrode 24. The bank 23 is formed in a grid-like region that partitions the pixel 4 in FIG. A second bank made of an inorganic material may be further formed between the bank 23 and the pixel electrode 24. The pixel electrode 24 and the bank 23 constitute a recess having the pixel electrode 24 as a bottom and the bank 23 as a side wall.

  A light emitting layer 25 is formed in the recess defined by the bank 23. In each of the pixels 4r, 4g, and 4b, a light emitting layer 25 that emits red, green, and blue light is formed. The light emitting layer 25 includes an organic light emitting layer. In addition to the organic light emitting layer, the light emitting layer 25 may further include various functional layers such as a hole transport layer, a hole injection layer, an electron transport layer, and an electron injection layer. A cathode 26 made of a metal such as MgAg is formed on substantially the entire viewing side of the light emitting layer 25 and the bank 23. The cathode 26 has a half mirror shape by forming a thin metal. A sealing layer 27 made of resin or the like is formed on the observation side of the cathode 26. The sealing layer 27 can suppress problems caused by entry of foreign matter such as moisture and gas into the light emitting layer 25. The sealing layer 27 can be omitted when the adhesive layer 34 performs the same function.

  The cathode 26 and the pixel electrode 24 correspond to a pair of electrodes. When a drive voltage is applied between the cathode 26 and the pixel electrode 24, a drive current flows through the light emitting layer 25. The light emitting layer 25 emits light with a luminance corresponding to the magnitude of the driving current. The light traveling from the light emitting layer 25 to the observation side passes through the cathode 26 and contributes to the display of the organic EL device 2. Further, the light traveling from the light emitting layer 25 to the back side and the light reflected by the cathode 26 to the back side are reflected by the reflective film on the back side of the pixel electrode 24 and then proceed to the observation side to travel through the organic EL device 2. Contributes to the display. Thus, all the light from the light emitting layer 25 is emitted to the opposite side (observation side) from the glass substrate 21. Such a configuration is called a top emission type.

  The light emitting element 28 is configured by elements including the pixel electrode 24, the light emitting layer 25, and the cathode 26. The pixel 4 (pixels L and R) described above includes the light emitting element 28. The area occupied by each pixel 4 is a rectangular area (FIG. 12A) surrounded by the bank 23 in a plan view. In the cross-sectional view of FIG. 13, for example, an area including the circuit element layer 22 to the cathode 26. It is. Alternatively, the pixel 4 may be defined from the pixel electrode 24 to the cathode 26. The pixel 4 emits light emitted from the light emitting element 28 to the observation side. The color filter 33 is disposed on the light emission side of the pixel 4, and the light emitted from the pixel 4 is incident on any color element 32 included in the color filter 33.

  A part of the color element 32 works as a light shielding member for red, green, or blue light emitted from the pixel 4, whereby the organic EL device 2 can perform directional display. it can. The principle of directional display by the action of the pixels 4r, 4g, 4b and the color filter 33 in the organic EL device 2 is the same as that in the first embodiment (FIGS. 4 to 8), and a description thereof will be omitted.

  Thus, according to the organic EL device 2 of the present embodiment, the first image and the second image can be directionally displayed in different ranges. At this time, since the color filter 33 functions as a mask for directional display, the organic EL device 2 does not need another light-shielding optical element (mask) to perform directional display. For this reason, the organic EL device 2 capable of directivity display can be configured with fewer components. In addition, since the color filter 33 that functions as a mask is formed between the glass substrate 21 and the glass substrate 31, it is not necessary to separately attach a substrate on which the mask is formed to the outside of the glass substrate 31. Thereby, the thickness of the organic EL device 2 can be reduced.

  For example, after the color filter substrate 30 is manufactured by forming the color filter 33 on the glass substrate 31, the organic EL device 2 having such a configuration is manufactured by using the color filter substrate 30 as a sealing substrate. Can be manufactured. That is, similarly to the conventional organic EL device, the organic EL device 2 can be manufactured by a process of sealing the element substrate 20 by attaching the color filter substrate 30 as a sealing substrate. Therefore, an additional step for adding a mask for directional display after sealing is not necessary.

  The color filter 33 is disposed between the glass substrate 21 and the glass substrate 31, and there is no glass substrate between the color filter 33 and the pixel 4. For this reason, the space | interval of the color filter 33 and the pixel 4 can be made small easily. Thereby, the first range 3L in which light constituting the first image is emitted and the second range 3R in which light constituting the second image is emitted can be greatly different. The distance between the color filter 33 and the pixel 4 can be easily adjusted by changing, for example, the height of the sealant 29, the size of the spacer included in the sealant 29, or the thickness of the adhesive layer 34.

  Moreover, since the light which comprises a 1st image and a 2nd image has permeate | transmitted the color element 32 of the color filter 33, it is a color compared with the light taken out directly from the pixel 4 (light emitting element 28). High purity. For this reason, the organic EL device 2 can perform high-quality display with high color reproducibility.

  Note that the third embodiment may be combined with the second embodiment. That is, the pixels L and R may be arranged in a checkered pattern as shown in FIG. 9A, and the color elements 32 may be arranged in a delta arrangement as shown in FIG. 9B. . According to such a configuration, it is possible to suppress a reduction in display resolution by the organic EL device 2.

(Electronics)
The liquid crystal device 1 and the organic EL device 2 described above can be used by being mounted on, for example, a display device 100 for a car navigation system as an electronic apparatus as shown in FIG. In the display device 100, the two images can be directionally displayed in different ranges by the liquid crystal device 1 or the organic EL device 2 incorporated in the display unit 110. For example, a map image can be displayed on the driver's seat side, and a movie image can be displayed on the passenger seat side. At that time, high-quality display with high color reproducibility can be performed. Further, the display device 100 can perform directional display with a simple configuration.

  The liquid crystal device 1 and the organic EL device 2 can be used for various electronic devices such as a mobile computer, a digital camera, a digital video camera, an in-vehicle device, and an audio device in addition to the display device 100.

  Various modifications can be made to the above embodiment. As modifications, for example, the following can be considered.

(Modification 1)
In the organic EL device 2 according to the third embodiment, the light emitting layer 25 that emits red, green, and blue light is formed in the pixels 4r, 4g, and 4b, respectively. The light emitting layer 25 that emits light of the same color (for example, white) may be formed on all the pixels 4. FIG. 14 is a cross-sectional view along the XZ plane of the organic EL device 2 according to this modification, and FIG. 15 is an enlarged view of FIG.

  As shown in FIG. 14, the color filter substrate 30 includes a glass substrate 31 as a base, a transparent resin layer 35 made of a color filter 33, a laminate film, and the like on the back surface of the glass substrate 31, a second color filter. The color filters 43 are stacked in this order. The planar arrangement of the color filter 33 and the color filter 43 is the same as that in the first embodiment, and is shown in FIGS. 2 (a) and 2 (b). It can be said that the color filter substrate 30 of the present modification has a configuration in which the common electrode 47 and the alignment film 48 are removed from the color filter substrate 30 (FIG. 3) according to the first embodiment.

  As shown in FIG. 15, the color filter 43 has color elements 42r, 42g, and 42b. The pixels 4r, 4g, and 4b are configured to include color elements 42r, 42g, and 42b, respectively. In each pixel 4, the white light emitted from the light emitting layer 25 passes through the color element 42 and is emitted from the pixel 4 as light having a color corresponding to the color of the color element 42. Therefore, the observation side surface of the color element 42 is substantially the light emission surface of the pixel 4. Even with such a configuration, the organic EL device 2 capable of directivity display with a simple configuration can be obtained as in the third embodiment. The light emitting layer 25 may be configured not to be partitioned by the bank 23, and may be formed in a continuous manner over substantially the entire organic EL device 2 so as to cover the bank 23, for example. Further, the light emitting layer 25 that emits white light may have a configuration in which a light emitting layer that emits light of blue light and a light emitting layer that emits yellow light are stacked. According to the light emitting layer 25 having such a configuration, a long-life light emitting element 28 can be obtained.

(Modification 2)
The organic EL device 2 according to the third embodiment adopts a top emission type, but may have a bottom emission type configuration instead. 16A and 16B are cross-sectional views along the XZ plane of the organic EL device 2 when the bottom emission type is employed.

  Among these, the organic EL device 2 shown in FIG. 16A is bonded to the element substrate 20, the sealing substrate 60 bonded to the back side of the element substrate 20 with a sealant 29, and the observation side of the element substrate 20. And a color filter substrate 30 bonded through the layer 34. The element substrate 20 includes a glass substrate 21 and a plurality of light emitting elements 28 formed on the back side of the glass substrate 21. The light-emitting element 28 has a configuration in which the light-emitting element 28 shown in FIG. 13 is reversed in the Z-axis direction. Of these, the cathode 26 is formed to a thickness that functions as a reflective film. Light emitted from the light emitting layer 25 of the light emitting element 28 is reflected to the observation side by the cathode 26. The light emitting element 28 is sealed with a sealing substrate 60 and a sealing agent 29. In the configuration of FIG. 16A, the sealing substrate 60 corresponds to the first substrate, and the glass substrate 31 of the color filter substrate 30 corresponds to the second substrate. Even with such a configuration, the color filter 33 can function as a mask for directional display, as in the third embodiment. Therefore, the bottom emission type organic EL device 2 capable of directivity display is obtained.

  Further, the organic EL device 2 shown in FIG. 16B is a combination of the configuration of FIG. 16A and the configuration of the first modification. In FIG. 16B, the color filter substrate 30 includes a glass substrate 31 as a base, and a transparent resin layer 35 and a color filter 43 made of a color filter 33, a laminate film, and the like on the back surface of the glass substrate 31. It has the structure laminated | stacked in this order. The light emitting layer 25 included in the light emitting element 28 of the element substrate 20 emits light of the same color (for example, white) in all the pixels 4.
