2. Description of the Related Art Conventionally, as one electro-optical device, a display device that can display a different image for each viewing direction (hereinafter referred to as directional display) when viewed from a plurality of directions is known. As such a display device, a configuration having a display panel and a barrier is known. The barrier has an opening and a light shielding part.
In a display device having a display panel and a barrier, different images can be displayed in each of the plurality of ranges through the opening of the barrier.
Among such display devices, there is a conventional display device that can divide a 360 ° panoramic view centering on the display device in a plan view into four ranges and perform directional display in each range (for example, Patent Documents). 1).

JP 2006-18282 A (pages 32 to 37, FIGS. 17 to 20)

Here, a mechanism for performing directional display of two types of images in different ranges on a display device having a display panel and a barrier will be described with reference to cross-sectional views. As shown in FIG. 26, the display panel 800 includes a first composite pixel 801 that displays a first image, and a second composite pixel 803 that displays a second image.
The first composite pixel 801 includes a pixel 801R that emits light of different colors, a pixel 801G, and a pixel 801B. The second composite pixel 803 also includes a pixel 803R that emits light of different colors, a pixel 803G, and a pixel 803B.
The adjacent first composite pixel 801 and second composite pixel 803 constitute a pair 804. The barrier 805 is provided with an opening 807 for each pair 804. A light shielding part 809 is located between adjacent openings 807.

  The light 811 from the first composite pixel 801 reaches the first range 813 through the opening 807. Light 815 from the second composite pixel 803 reaches the second range 817 through the opening 807. That is, the first image can be viewed from the viewpoint within the first range 813, and the second image can be viewed from the viewpoint within the second range 817. Note that the first range 813 and the second range 817 have a range 819 overlapping each other. From the viewpoint within the range 819, an image in which the first image and the second image are superimposed is visually recognized. For this reason, the range 819 is referred to as an overlapping range 819.

From the viewpoint within the range 821 excluding the overlapping range 819 from the first range 813, only the first image can be viewed. From the viewpoint in the range 823 excluding the overlapping range 819 from the second range 817, only the second image can be viewed.
Incidentally, in the first composite pixel 801, the positions of the pixel 801R, the pixel 801G, and the pixel 801B are different from each other. Similarly, in the second composite pixel 803, the positions of the pixel 803R, the pixel 803G, and the pixel 803B are also different from each other.
Of the light 811 from the first composite pixel 801, the light 811R emitted from the pixel 801R covers a range 831 as shown in FIG. Similarly, the light 811G emitted from the pixel 801G reaches the range 833, and the light 811B emitted from the pixel 801B extends to the range 835.

In the range 821 where only the first image can be visually recognized, all of the light 811R, the light 811G, and the light 811B can be visually recognized only in the range 837. A range 837 is a range in which the range 831, the range 833, and the range 835 overlap within the range 821.
In the range excluding the range 837 from the range 821, the light 811B cannot be visually recognized. That is, in this state, although the viewpoint is located within the range 821, the light 811B cannot be visually recognized. This means that the observer is viewing the first image with the light 811B missing. In this state, the hue of the first image is not correctly expressed. That is, the range excluding the range 837 from the range 821 is a range in which the image display quality is impaired.

  As described above, the conventional electro-optical device has a problem that it is difficult to reduce the range in which the display quality of the image is impaired.

The cross section of the liquid crystal panel 11 in FIG. 9 corresponds to the cross section along the line HH in FIG.

In the display device 1 having the above-described configuration, the display is controlled by changing the alignment state of the liquid crystal 25 for each pixel 7 in a state in which the illumination device 5 irradiates the display panel 3 with light. The alignment state of the liquid crystal 25 can be changed by controlling a voltage applied between the pixel electrode 73 and the counter electrode 93 (hereinafter referred to as a drive voltage).
Each of the alignment film 69 and the alignment film 95 is subjected to an alignment process. The initial alignment state of the liquid crystal 25 is regulated by the alignment film 69 and the alignment film 95 that have been subjected to the alignment treatment.
In the display device 1, the liquid crystal 25 is in an off state when the driving voltage is 0V. When the drive voltage increases, the liquid crystal 25 is driven by the electric field generated between the pixel electrode 73 and the counter electrode 93. The state in which the liquid crystal 25 is driven is called an on state.

FIG. 16A is a diagram illustrating a polarization state in the liquid crystal panel 11 when the liquid crystal 25 is in an off state. FIG. 16B is a diagram illustrating a polarization state in the liquid crystal panel 11 when the liquid crystal 25 is in an on state.
In the display device 1, the transmission axis direction 161a of the polarizing plate 19a is orthogonal to the transmission axis direction 161b of the polarizing plate 19b in plan view, as shown in FIGS. 16 (a) and 16 (b). The alignment direction 163 of the alignment film 69 is along the transmission axis direction 161a in plan view. The alignment direction 165 of the alignment film 95 is orthogonal to the transmission axis direction 161a in plan view.
16 (a) and 16 (b), the X ′ direction and the Y ′ direction indicate the direction along the transmission axis direction 161b of the polarizing plate 19b in a plan view, and the Y ′ direction. Indicates a direction orthogonal to the X ′ direction in the XY plane. The X ′ direction and the Y ′ direction are arbitrary two directions orthogonal to each other in the XY plane.

Incident light that has entered the polarizing plate 19a from the light source 33 through the light guide plate 31 enters the liquid crystal 25 as linearly polarized light 167 having a polarization axis along the transmission axis direction 161a of the polarizing plate 19a, that is, the Y ′ direction. .
When the liquid crystal 25 is off, the linearly polarized light 167 incident on the liquid crystal 25 is directed toward the polarizing plate 19b as linearly polarized light 169 having a polarization axis along the X ′ direction as shown in FIG. It is injected. The linearly polarized light 169 emitted toward the polarizing plate 19b passes through the polarizing plate 19b because the direction of the polarization axis is along the direction 161b of the transmission axis of the polarizing plate 19b.

  On the other hand, when the liquid crystal 25 is in the ON state, as shown in FIG. 16B, the linearly polarized light 167 is emitted toward the polarizing plate 19b as the linearly polarized light 167 while maintaining the polarization state. The linearly polarized light 167 emitted toward the polarizing plate 19b is absorbed by the polarizing plate 19b because the direction of the polarization axis is orthogonal to the direction 161b of the transmission axis of the polarizing plate 19b.

  In the display device 1, light is emitted from the liquid crystal panel 11 toward the display surface 9 when the liquid crystal 25 is in an off state, and light emission from the liquid crystal panel 11 is blocked when the liquid crystal 25 is in an on state. The white (initially “white display”) display mode is used. However, the display mode is not limited to normally white, and so-called normally black (initially “black display” state) can also be adopted.

As described above, the display device 1 includes the light shielding film 103 in which the opening 111 is provided for each pixel group 55. Light incident on each pixel 7 from the illumination device 5 is emitted to the display surface 9 side through the opening 111.
At this time, the light 181 emitted toward the display surface 9 side from the first pixel 7 ₁ is schematic sectional view of a cutaway of the liquid crystal panel 11 and the light-shielding film 103 at line F-F in FIG. 11 As shown in FIG. 17, the first range 183 is reached through the opening 111.
Further, the light 185 emitted toward the display surface 9 side from the second pixels 7 _2, to a second range 187 through the openings 111.

From the first range 183, the light 181 from the _first pixel 71 emitted through each opening 111 can be visually recognized. From the second range 187, the light 185 from the _second pixel 72 emitted through each opening 111 can be visually recognized.
When an eye point within the first range 183, a first image formed by the light 181 from the plurality of first pixels 7 ₁ can be viewed. When an eye point within the second range 187, a second image formed by the light 185 from the plurality of second pixels 7 ₂ can be viewed.

Therefore, in the display device 1, the first image can be displayed in the first range 183 and the second image can be displayed in the second range 187. The first range 183 and the second range 187 are different from each other.
Thus, the display device 1 can perform directional display in a plurality of different ranges in the Y direction.
Note that the first range 183 and the second range 187 have a range 189 that overlaps each other (hereinafter referred to as the overlapping range 189).

On the other hand, the third pixel 7 ₃ light 201 emitted toward the display surface 9 side from, in a schematic diagram of a cutaway of the liquid crystal panel 11 and the light-shielding film 103 with line E-E in FIG. 11 As shown in FIG. 18, the third range 203 is reached through the opening 111.
Further, the light 205 emitted toward the display surface 9 side from the fourth pixel 7 ₄ spans the fourth range 207 through the openings 111.

From the third range 203, the light 201 from the _third pixel 73 emitted through each opening 111 can be viewed. From the fourth range 207, the light 205 from the _fourth pixel 74 emitted through each opening 111 can be visually recognized.
When an eye point within the third range 203, a third image formed by the light 201 from the plurality of third pixels 7 ₃ can be viewed. When an eye point in the fourth range 207, a fourth image formed by the light 205 from the plurality of fourth pixels 7 ₄ can be viewed.

Therefore, the display device 1 can display the third image in the third range 203 and the fourth image in the fourth range 207. The third range 203 and the fourth range 207 are different from each other.
Thus, the display device 1 can perform directional display in a plurality of different ranges in the X direction.

As described above, the display device 1 can perform directivity display in each of the first range 183 and the second range 187 in the Y direction. In the X direction, directivity display can be performed in each of the third range 203 and the fourth range 207.
The first range 183, the second range 187, the third range 203, and the fourth range 207 are different from each other. Thus, the display device 1 can perform directional display in a plurality of different ranges (four ranges in this embodiment) in both the X direction and the Y direction.

In the present embodiment, the light shielding film 103 and the opening 111 correspond to the optical element, the Y direction corresponds to the first direction, and the X direction corresponds to the second direction.
In the present embodiment, the opening 111 provided in the light shielding film 103 corresponds to the pixel group 55. That is, the opening 111 is provided for each pixel group 55. The pixel group 55 includes a first pixel 7 ₁ and second pixel 7 _2, the third pixel 7 _3, and a fourth pixel 7 ₄ are included one by one.

The light from the four pixels 7 in the set of pixel groups 55 reaches different ranges for each pixel 7 through the opening 111. That is, in the present embodiment, the range over which the light forming each of the first image to the fourth image extends is defined for each pixel 7.
For this reason, for example, compared with the case where the range covered by the light forming each of the first image to the fourth image is defined by the unit of the composite pixel 54, the range covered by the light of R, G, and B is imaged. You can make it easier to fit each
As a result, it is possible to easily reduce the range in which the display quality of each image is impaired.

In the present embodiment, in the display region 6 shown in FIG. 4, the diagonal line 46a and the diagonal line 46b extend in directions intersecting with the X direction and the Y direction, respectively. Therefore, the direction in which the first range 183 and the second range 187 extend can be shifted from the direction in which the diagonal line 46a and the diagonal line 46b extend. Similarly, the direction (X direction) in which the third range 203 and the fourth range 207 extend can also be shifted from the direction in which the diagonal line 46a and the diagonal line 46b extend.
Thereby, the direction of the first image and the second image in the directional display (Y direction) and the direction of the third image and the fourth image in the directional display (X direction) are represented by the diagonal line 46a and the diagonal line. 46b can be shifted from the extending direction.

Further, in the present embodiment, the display area 6 is set to a quadrilateral having sides 43a and 43b extending along the X direction and sides 43c and 43d extending along the Y direction. . For this reason, it is possible to easily match the direction in which the first range 183 and the second range 187 extend with the direction in which the side 43c and the side 43d extend. Similarly, the direction in which the third range 203 and the fourth range 207 extend and the direction in which the side 43a and the side 43b extend can be easily matched.
For this reason, it is possible to easily match the direction (Y direction) of the first image and the second image in the directional display with the direction in which the side 43c and the side 43d extend. Similarly, the direction (X direction) of the third image and the fourth image in the directional display can be easily matched with the direction in which the side 43a and the side 43b extend.

Thereby, for example, an observer who observes the directional display can easily observe each image by confronting the quadrilateral display region 6 along the X direction or the Y direction. This is because, for example, when observing a directional display, the observer feels uncomfortable as compared to the case where the diagonal line 46a and the diagonal line 46b face each other with respect to the quadrilateral display area 6. This is because it can be made difficult to feel.
Further, for example, the directions of the first image and the second image in the directional display, and the directions of the third image and the fourth image in the directional display are along the direction in which the diagonal line 46a and the diagonal line 46b extend. The observer observes an irregular display area such as a diamond. In the irregular display area, the observer feels a strong sense of incongruity.
For the reasons described above, the direction of the first image and the second image in the directional display (Y direction) and the direction of the third image and the fourth image in the directional display (X direction) It is preferable to deviate from the direction in which the diagonal line 46a and the diagonal line 46b extend.

In the present embodiment, the pixel 7 is partitioned by a quadrilateral having a first side 37a extending in the Y direction and a second side 37b extending in the X direction. The plurality of pixel groups 55 are arranged in the V direction intersecting the X direction and the Y direction. With this configuration, the arrangement density (resolution) of the pixel group 55 can be easily increased. As a result, the arrangement density (resolution) of the pixels 7 can be easily increased.
Thereby, it is possible to easily increase the definition of each image in the directional display. For this reason, in this embodiment, the display quality in the directional display can be easily improved.

  In the present embodiment, the first side 37a of the pixel 7 is longer than the second side 37b. In other words, the second side 37b is shorter than the first side 37a. For this reason, the resolution in the X direction can be higher than the resolution in the Y direction. As a result, it is possible to further increase the definition of each image in the directional display, and to further improve the display quality in the directional display.

In the present embodiment, an array configuration M1 (FIG. 3) in which the colors of R, G, and B light are defined for each pixel column 51 is employed. However, the arrangement of R, G and B is not limited to the arrangement configuration M1.
As the arrangement of R, G, and B, for example, as shown in FIG. 19, an arrangement in which R, G, and B are arranged in the Y direction may be employed. The array configuration shown in FIG. 19 is referred to as an array configuration M2.
In the array configuration M2, in one pixel column 51, the pixel 7R, the pixel 7G, and the pixel 7B are continuously arranged. In one pixel column 51, sets of pixels 7R, pixels 7G, and pixels 7B that are continuously arranged repeatedly appear in the Y direction.

In another aspect, in the arrangement configuration M2, the plurality of pixels 7R are arranged in every other column of the pixel columns 51 along the X direction. Similarly, the plurality of pixels 7G are also arranged in every other column of the pixel column 51 along the X direction, and the plurality of pixels 7B are also arranged in every other column of the pixel column 51 along the X direction.
In this arrangement configuration M2, the same effects as in the arrangement arrangement M1 can be obtained.

For example, an array configuration M3 illustrated in FIG. 20 may be employed as an array in which the pixels 7R, 7G, and 7B are continuously arranged in one pixel column 51.
Similar to the array configuration M2, the array configuration M3 includes a set of pixels 7R, 7G, and 7B that are continuously arranged in one pixel column 51 and repeatedly appear in the Y direction.
However, the array configuration M3 is different from the array configuration M2 in that R, G, and B are defined in units of the array 56 of the pixels 7 arranged in a zigzag manner in the X direction.
In this arrangement configuration M3, the same effect as the arrangement arrangement M1 and arrangement arrangement M2 can be obtained.

Further, as the arrangement of R, G, and B, for example, as shown in FIG. 21, an arrangement that defines R, G, and B for each pixel group 55 may be employed. The array configuration shown in FIG. 21 is referred to as an array configuration M4. In the array configuration M4, the pixel group 55 is identified as a pixel group 55R having four pixels 7R, a pixel group 55G having four pixels 7G, and a pixel group 55B having four pixels 7B.
Also in this arrangement configuration M4, the same effects as the arrangement configuration M1, the arrangement configuration M2, and the arrangement configuration M3 are obtained. In the arrangement configuration M4, R, G, and B are defined in units of columns of the pixel group 55 arranged in the Y direction. In this respect, the arrangement according to the arrangement M1 is employed in the arrangement M4.
The arrangement that defines R, G, and B for each pixel group 55 is not limited to the arrangement configuration M4, and various arrangements based on the arrangement configuration M2, the arrangement configuration M3, and the like can be adopted.

In the present embodiment, a plurality of sets of pixel groups 55 are arranged along the V direction as shown in FIG. However, the direction in which the plurality of sets of pixel groups 55 are arranged is not limited to the V direction. For example, as illustrated in FIG. 22, a W direction that is inclined from the V direction may be employed. The W direction is a direction that intersects any of the X direction, the Y direction, and the V direction. The arrangement configuration illustrated in FIG. 22 is referred to as an arrangement configuration M5.
In the arrangement configuration M5, the same effects as those of the arrangement configurations M1 to M4 can be obtained.

In the present embodiment, the second side 37b of the pixel 7 is set to a shorter length than the first side 37a, as shown in FIG. However, the length of the second side 37b is not limited to a length shorter than the first side 37a, and a length longer than the first side 37a may be employed as shown in FIG. The arrangement configuration illustrated in FIG. 23 is referred to as an arrangement configuration M6.
In the arrangement configuration M6, the arrangement of the pixel group 55 may be an arrangement according to the arrangement configuration M1 (FIG. 8) or the arrangement configuration M5 (FIG. 22). In the array configuration M6, as the R, G, and B sequences, various sequences according to each of the array configurations M1 to M4 can be adopted.
In the arrangement configuration M6, the same effects as those of the arrangement configurations M1 to M5 can be obtained.
Furthermore, in the arrangement configuration M6, since the first side 37a is shorter than the second side 37b, the resolution in the Y direction can be higher than the resolution in the X direction.

Further, as the length of the second side 37b of the pixel 7, as shown in FIG. 24, a length equivalent to the length of the first side 37a may be employed. The array configuration shown in FIG. 24 is referred to as an array configuration M7.
In the arrangement configuration M7, the arrangement of the pixel group 55 may be an arrangement according to the arrangement configuration M1 (FIG. 8) or the arrangement configuration M5 (FIG. 22). In the array configuration M7, as the R, G, and B arrays, various sequences according to the array configurations M1 to M4 can be adopted.
In the arrangement configuration M7, the same effects as those of the arrangement configurations M1 to M5 are obtained.
Furthermore, in the arrangement configuration M7, since the first side 37a and the second side 37b have the same length, the difference between the resolution in the X direction and the resolution in the Y direction can be reduced.

In the present embodiment, the pixel group 55 includes four pixels 7. However, the number of pixels 7 included in the pixel group 55 is not limited to four, and an arbitrary number of four or more can be adopted.
In the display device 1, the TN liquid crystal 25 has been described as an example. However, the liquid crystal 25 is not limited to this, and may be an FFS (Fringe Field Switching) type, an IPS (In Plane Switching) type, or a VA (Vertical Alignment) type. Various types such as can be adopted.
