Description

  The present invention relates to an electro-optical device.

Conventionally, a plurality of first pixels and a plurality of second pixels each provided with a display element are arranged in a matrix in the image display area, and the image display area is located on the viewing side of the image display area. And a plurality of openings that partially expose each of the first pixel and the second pixel, and the openings are the first pixel from the first direction. However, only the second pixel is visible from the second direction, and the angle formed by the first direction and the normal of the image display area is smaller than the angle formed by the second direction and the normal. An optical device is known (see, for example, Patent Document 1).

According to the multi-view display device described in Patent Document 1, an image for a driver's seat such as a navigation image is displayed on the driver side of the driver's seat, and a passenger's seat for a passenger seat such as a DVD image is displayed on the passenger in the passenger seat. Images can be displayed. Furthermore, in order to prevent the driver from looking into the passenger seat side from the viewpoint of traffic safety, the position of the light shielding portion is defined by the pixels constituting the driver seat image and the passenger seat image. A technique is disclosed in which a range in which an image for a passenger seat can be seen is shifted to the passenger seat side by shifting it from the middle of the constituent pixels to the passenger seat side so that it is difficult to see from the driver seat side.
JP 2006-184860 A

However, in the conventional electro-optical device, the field of view of the passenger seat image is narrower than the field of view of the driver seat image, so the brightness of the image for the passenger seat is the brightness of the image for the driver seat. There is a problem that it becomes darker than it is.

Accordingly, the present invention provides an electro-optical device that can make the brightness of each image uniform even when the field-of-view ranges of different images displayed in different directions are different.

In order to solve the above problems, in the electro-optical device according to the present invention, a plurality of first pixels and a plurality of second pixels each having a display element are arranged in a matrix in the image display region. A light-shielding member that is planarly overlapped with the image display region is disposed on the viewing side of the image display region, and the light-shielding member has an opening that partially exposes each of the first pixel and the second pixel. A plurality of sections are arranged so that only the first pixel is visible from the first direction of the opening, and only the second pixel is visible from the second direction, and the second direction is the image display An electro-optical device in which an angle formed with a normal line of the region is larger than an angle formed by the first direction with the normal line, and the first pixel and the second pixel are arranged in a vertical direction of the image display region and The first pixels are alternately arranged in the horizontal direction. The area of the transmission region is equal to or larger than the area of the light transmission region of the second pixel.

By comprising in this way, the 2nd direction through the opening part of the light shielding member from the 2nd direction rather than the visual field range of the 1st pixel which can visually recognize the 1st pixel through the opening part of the light shielding member from the 1st direction The visual field range of the second pixel where the pixel can be visually recognized becomes narrower. That is, the area of the first pixel that can be seen through the opening when the observer sees the first pixel from the first direction is the second area that can be seen through the opening when looking at the second pixel from the second direction. It becomes larger than the area of the pixel.
Here, in the present invention, the area of the light transmission region of the first pixel is formed smaller than the area of the light transmission region of the second pixel. Therefore, the difference between the area of the light transmissive region of the first pixel visible from the first direction and the area of the light transmissive region of the second pixel visible from the second direction is reduced, Or can be eliminated.
Therefore, according to the electro-optical device of the present invention, even if the visual field range in the first direction is wider than the visual field range in the second direction, the first pixel is configured to display in the first direction. The brightness of the displayed image and the brightness of the image composed of the second pixels and displayed in the second direction can be made uniform.

In the electro-optical device according to the aspect of the invention, the vertical width of the light transmission region of the first pixel may be
It is smaller than the vertical width of the light transmission region of the second pixel.

By configuring in this way, the vertical width of the light transmission region of the first pixel and the second pixel is adjusted, and the area of the light transmission region of the first pixel is made larger than the area of the light transmission region of the second pixel. Can be small.

In the electro-optical device according to the aspect of the invention, the lateral width of the light transmission region of the first pixel may be
The width of the light transmission region of the second pixel is smaller than the width in the lateral direction.

By configuring in this way, the lateral width of the light transmission region of the first pixel and the second pixel is adjusted, and the area of the light transmission region of the first pixel is made larger than the area of the light transmission region of the second pixel. Can be small.

The thin film transistor is formed in the vicinity of a boundary between the first pixel and the second pixel adjacent to each other in the vertical direction.

With this configuration, the boundary on the side where the thin film transistor of the first pixel is not formed and the boundary on the side where the thin film transistor of the second pixel are not formed can be adjacent to each other in the vertical direction of the image display region. it can. Thereby, the freedom degree of the area adjustment of each light transmissive area | region in the 1st pixel and 2nd pixel which adjoin a vertical direction can be improved.

As illustrated in FIG. 3, the liquid crystal device 1 includes an element substrate 21 and a counter substrate 22 that sandwich the liquid crystal layer 23. The element substrate 21 includes a substrate body 31 made of a translucent material such as glass, quartz, or plastic. Although not shown in FIG. 3, the data lines 14R and 14L, the scanning lines 16R and 16L, the capacitor line 19 and the like shown in FIG. 1 are formed on the substrate body 31, and the TFT elements 12R A functional layer 32 including 12L and storage capacitors 18R and 18L is formed.

Functional layer 32 may be, for example, a gate insulating film made of an insulating material such as SiO _2, TFT elements 12R formed on the gate insulating film, the interlayer insulating film or the like made of an insulating material such as SiO ₂ which covers the semiconductor layer 12L It is configured.
The pixel electrodes 11R and 11L described above are formed on the surface of the functional layer 32 on the liquid crystal layer 23 side. The pixel electrodes 11R and 11L are formed of a transparent conductive material such as ITO (indium tin oxide). The pixel electrodes 11R and 11L are connected to the drains of the TFT elements 12R and 12L through contact holes (not shown) formed in the functional layer 32.

In addition, on the surface of the functional layer 32 on the liquid crystal layer 23 side, the pixel electrodes 11R and 11L are covered.
For example, an alignment film 33 made of an organic material such as polyimide or an inorganic material such as silicon oxide is formed. An alignment process is performed on the upper surface of the alignment film 33 to regulate alignment of the liquid crystal molecules constituting the liquid crystal layer 23. A polarizing plate 24 is bonded to the outside of the element substrate 21 (on the opposite side of the liquid crystal layer 23). Further, a backlight device (not shown) including a light source such as an LED, a reflection plate, a light guide plate, and the like is disposed outside the element substrate 21.

The counter substrate 22 disposed to face the element substrate 21 includes a substrate body 51 made of a light-transmitting material such as glass, quartz, or plastic. Inside the substrate body 51 (liquid crystal layer 2
On the third side), a light shielding film 52 is formed of a material having a light shielding property such as chromium, for example. The light shielding film 52 has openings 5 corresponding to the right sub-pixel R and the left sub-pixel L, respectively.
2R and an opening 52L are formed. The formation regions of the opening 52R and the opening 52L are light transmission regions of the right sub-pixel R and the left sub-pixel L, respectively.

A color filter layer 53 is disposed in the formation region of the opening 52R and the opening 52L. The color filter layer 53 includes red (R), green (G), and blue (B) color materials.
2 and 3, the right sub-pixel R and the left sub-pixel L on which the red (R) color material of the color filter layer 53 is arranged are denoted by “R (R)” and “L (R)”, respectively. It expresses. Similarly, each of the right sub-pixel R and the left sub-pixel L on which the green (G) color material is arranged is referred to as “R (G)”.
”,“ L (G) ”, and the right subpixel R and the left subpixel L on which the blue (B) color material is arranged are represented as“ R (B) ”and“ L (B) ”, respectively.

As shown in FIG. 2, in the present embodiment, the vertical width (Y-axis direction) width WR1 of the opening 52R of the right sub-pixel R is smaller than the vertical width WL1 of the opening 52L of the left sub-pixel L. ing. The width WR2 in the horizontal direction (X-axis direction) of the right sub-pixel R is the width WL in the horizontal direction of the left sub-pixel L.
It is almost equal to 2. Thereby, the opening area of the opening 52R of the right sub-pixel R is formed to be smaller than the opening area of the opening 52L of the left sub-pixel L, and the area of the light transmission region of the right sub-pixel R is the left sub-pixel. It is smaller than the area of the L light transmission region. Therefore, the light transmission region of the pixel that is configured by the right sub-pixels R (R), R (G), and R (B) and displays the image for the driver's seat is the left sub-pixels L (R), L ( G) and L (B), which are smaller than the light transmission region of the pixel for displaying the passenger seat image.

As shown in FIG. 3, a common electrode 41 is formed on the color filter layer 53 and the light shielding film 52 on the liquid crystal layer 23 side. The common electrode 41 is formed across a plurality of pixels in substantially the entire pixel display area of the liquid crystal device 1. The common electrode 41 is made of, for example, a transparent conductive material such as ITO.
On the liquid crystal layer 23 side of the common electrode 41, an alignment film 54 made of an organic material such as polyimide or an inorganic material such as silicon oxide is formed so as to cover the common electrode 41.

On the outside of the substrate body 51 of the counter substrate 22 (opposite side of the liquid crystal layer 23), that is, on the viewing side (Z-axis positive direction side) of the liquid crystal device 1, the light shielding member 55 is made of a light shielding material such as chromium.
Is formed. The light shielding member 55 includes pixel electrodes 11R and 11L and TFT elements 12R and 1
Display elements including 2L (see FIG. 1) and the like are arranged so as to planarly overlap the image display area of the liquid crystal device 1 arranged in a matrix in the normal direction (Z-axis direction). The light shielding member 55 is formed with a plurality of slit openings (openings) 55S.

As shown in FIG. 2, the slit opening 55S of the light shielding member 55 is opened in a substantially rectangular shape between the right sub-pixel R and the left sub-pixel L adjacent to each other in the horizontal direction of the image display region. The slit opening 55S is formed so as to partially expose the right sub-pixel R and the left sub-pixel L that are alternately arranged in the horizontal and vertical directions of the image display area.

As shown in FIGS. 3 and 4, the slit opening 55S has a right sub-pixel R on the left side (Y-axis negative direction side) and a right side (Y-axis positive direction side) in the horizontal direction of the image display area. Left sub-pixel L
Is formed to be exposed. Thus, the slit openings 55S are formed in a checkered pattern in which the slit openings 55S adjacent in the vertical direction of the image display area are alternately arranged in the horizontal direction. When the image display area is viewed from the direction of the line, the area of the right sub-pixel R exposed from the light shielding member 55 by the slit opening 55S is the slit opening 5
It is larger than the area of the left sub-pixel L exposed to 5S.

Therefore, as shown in FIGS. 3 and 4, the slit opening 55 </ b> S is from the first direction D <b> 1 on the driver seat side that forms an angle θ <b> 1 with the normal direction (Z-axis direction) of the image display region of the liquid crystal device 1. Only the left sub-pixel L is formed so as to be visible through the slit opening 55S. From the second direction D2 on the passenger seat side that forms an angle θ2 with the normal direction of the image display region, the right sub-pixel passes through the slit opening 55S. Only R is visible. Further, the angle θ2 formed by the second direction D2 on the passenger seat side and the normal direction is formed to be larger than the angle θ1 formed by the first direction D1 on the driver seat side and the normal direction. Is difficult to look into from the driver's seat side.

Next, the operation of this embodiment will be described.
In the present embodiment, as shown in FIG. 4, the liquid crystal device 1 is a driver's seat of the automobile (the handle H side).
Is installed in front of the driver Dv and the passenger Ps in the passenger seat. Here, as shown in FIGS. 2 and 3, the opening 55 </ b> S of the light shielding member 55 is shifted from the middle between the right sub-pixel R and the left sub-pixel L to the passenger seat side (X-axis negative direction side). Therefore, as shown in FIG. 4, the visual field range VR1 of the right sub-pixel R, which is the range in which the right sub-pixel R can be viewed through the slit opening 55S of the light shielding member 55 from the first direction D1 on the driver's seat side, The visual field range VR2 of the left sub-pixel L, which is the range in which the right sub-pixel R can be viewed through the slit opening 55S of the light shielding member 55 from the second direction D2 on the passenger seat side, is narrower.

That is, the area of the right sub-pixel R that the driver Dv can see through the slit opening 55S of the light shielding member 55 from the angle θ1 (the angle at which the luminance of the image viewed from the first direction D1 is maximized) is greater. However, the angle is larger than the area of the left sub-pixel L that can be seen through the slit opening 55S from the angle θ2 (the angle at which the luminance of the image viewed from the second direction D2 is maximized).

Here, in this embodiment, the opening area of the opening 52L of the light shielding film 52 in the left subpixel L is formed smaller than the opening area of the opening 52R of the light shielding film 52 in the right subpixel R. The area of the light transmissive region of the right sub-pixel R is formed smaller than the area of the light transmissive region of the left sub-pixel L. Therefore, the area of the light transmission region of the right sub-pixel R that can be visually recognized by the driver Dv in the first direction D1 on the driver's seat side, and the left that can be viewed by the passenger Ps in the second direction D2 on the passenger seat side. The difference from the area of the light transmission region of the sub-pixel L can be reduced or eliminated.

FIG. 5 is a graph showing the relationship between the inclination angle θ from the normal direction (Z-axis direction) of the image display area of the liquid crystal device 1 and the luminance. Here, the inclination angle θ is positive for the inclination from the normal direction to the passenger seat direction (X-axis negative direction in FIG. 4) and negative for the driver seat direction (X-axis positive direction in FIG. 4).
In FIG. 5, the data of the liquid crystal device 1 of the present embodiment is represented by a solid line d1. Also, in the figure, data of a liquid crystal device having the same configuration as that of the liquid crystal device of the present embodiment except that the areas of the light transmission regions of the right sub-pixel R and the left sub-pixel L are equal are indicated by a two-dot chain line d2. ing. Further, in the present embodiment, the areas of the light transmission regions of the right sub-pixel R and the left sub-pixel L are made equal, and the slit opening of the light shielding member 55 is formed between the right sub-pixel R and the left sub-pixel L. Data of a liquid crystal device having the same configuration as that of the liquid crystal device 1 is indicated by a broken line d3. In the drawing, a dotted line d0 is data of a liquid crystal device in which no light shielding member is provided.

As shown in FIG. 5, when the light shielding member 55 is not provided in the liquid crystal device 1, the dotted line d
As indicated by 0, the luminance gradually decreases as the inclination angle θ from the normal direction increases in the positive and negative directions.
In the case of the liquid crystal device indicated by the broken line d3, the luminance of the peak P3 at which the luminance is maximum on the passenger seat side and the peak P3 at which the luminance is maximum on the driver seat side are substantially equal. However, the magnitude of the inclination θ at the luminance peak P3 on the passenger seat side (θ axis positive direction side) and the inclination θ at the luminance peak P3 on the driver seat side (θ axis negative direction side) is, for example, θ = ± 30. It is almost equal before and after °. Therefore, the driver Dv on the driver's seat side can easily look into the passenger seat image.

In the case of the liquid crystal device indicated by the two-dot chain line d2, the luminance peak P2d on the driver's seat side is larger than the luminance peak P2p on the passenger seat side. However, since the same light shielding member 55 as that of the liquid crystal device 1 of the present embodiment is provided, the peak P2d and the peak P2p are shifted to the passenger seat side, and the driver Dv can be prevented from looking into.
On the other hand, in the liquid crystal device 1 of the present embodiment indicated by the solid line d1, the luminance peak P1 on the driver's seat side and the luminance peak P2 on the passenger seat side are substantially equal. In addition, the peaks P1 and P1 are shifted to the passenger seat side.

Therefore, according to the liquid crystal device 1 of the present embodiment, even when the visual field range VR1 in the first direction D1 on the driver's seat side is wider than the visual field range VR2 in the second direction D2 on the passenger seat side, The brightness of the driver's seat image displayed in the first direction D1 on the driver's seat side, which is composed of pixels composed of the right sub-pixel R, and the second on the passenger seat side composed of pixels composed of the left sub-pixel L. The brightness of the passenger seat image displayed in the direction D2 can be made uniform.

In the present embodiment, the vertical width of the light transmissive region of the right sub-pixel R is formed to be smaller than the vertical width of the light transmissive region of the left sub-pixel L. By adjusting the size relationship of the light transmission region of the pixel L, the area of the light transmission region of the right sub-pixel R can be made smaller than the area of the light transmission region of the left sub-pixel L.

That is, since the TFT elements 12R, 12L, wirings, and the like are not formed between the right sub-pixel R and the left sub-pixel L adjacent in the vertical direction in the unit array Ux, the light shielding films 52 of the right sub-pixel R and the left sub-pixel L. The degree of freedom in adjusting the opening area of the openings 52R and 52L is improved. Therefore, the degree of freedom in adjusting the area of each light transmission region of the right sub-pixel R and the left sub-pixel L can be improved.

<Third embodiment>
Next, a third embodiment of the present invention will be described with reference to FIG. 7 with reference to FIGS. 1 and 3 to 5. In the present embodiment, the lateral width WR2 of the opening 52R of the light shielding film 52 of the right subpixel R is formed smaller than the width WL2 of the opening 52R of the light shielding film 52 of the left subpixel L, and the opening 5
It differs from the liquid crystal device 1 described in the first embodiment in that the vertical widths WR1 and WL1 of 2R and 52L are substantially equal. Since the other points are the same as in the first embodiment, the same parts are denoted by the same reference numerals and description thereof is omitted.

In the liquid crystal device 1C of the present embodiment, the lateral width WR2 of the opening 52R of the light shielding film 52 of the right subpixel R is smaller than the lateral width WL2 of the opening 52L of the light shielding film 52 of the left subpixel L. It has become. As a result, the area of the light transmission region of the right sub-pixel R is smaller than the area of the light transmission region of the left sub-pixel L.
Therefore, according to the present embodiment, the lateral widths WR2 and WL2 of the light transmission regions of the right subpixel R and the left subpixel L are adjusted, and the area of the light transmission region of the right subpixel R is adjusted to the left subpixel L. The area of the light transmission region can be made smaller.

Next, a fourth embodiment of the present invention will be described with reference to FIG. 8 with reference to FIGS. 1 and 3 to 5. In the present embodiment, the TFT elements 12R and 12L of the right sub-pixel R and the left sub-pixel L adjacent in the horizontal direction of the image display area are alternately arranged on the left and right boundaries in the horizontal direction. This is different from the liquid crystal device 1C described in the third embodiment. Since the other points are the same as in the third embodiment, the same parts are denoted by the same reference numerals and the description thereof is omitted.

As shown in FIG. 8, in the liquid crystal device 1D of the present embodiment, the right sub-pixel R and the left sub-pixel L that are adjacent to each other in the horizontal direction (X-axis direction) of the image display region are in the vertical direction (Y-axis direction).
