In the drawings, the same or corresponding parts are denoted by the same reference numerals and description thereof will not be repeated. In addition, in order to make the explanation easy to understand, in the drawings referred to below, the configuration is shown in a simplified or schematic manner, or some components are omitted. Further, the dimensional ratio between the constituent members shown in each drawing does not necessarily indicate an actual dimensional ratio.

[First Embodiment]
FIG. 1 is a cross-sectional view illustrating a schematic configuration of a display device 10 according to the first embodiment. FIG. 1 shows a cross-sectional view of the display device 10 taken along a horizontal plane. The display device 10 is a head mounted display that is used by being mounted on the head. The display device 10 includes a display panel 1 and an eyepiece lens 2.

The display panel 1 is, for example, a liquid crystal panel, and the resolution thereof is, for example, 800 ppi. In the present embodiment, the display panel 1 is described as a liquid crystal panel. However, the display panel 1 is not limited to a liquid crystal panel, and may be any panel having a function of displaying an image, such as an organic EL (Electro Luminescence) panel. good.

The display panel 1 includes a glass substrate (active matrix substrate) 11, a plurality of pixel electrodes 12 arranged in a matrix on the glass substrate 11, and a plurality of bus lines (scanning lines and data) arranged on the glass substrate 11. Line) 13, a glass substrate (color filter substrate) 14 facing the glass substrate 11,

color filters

15R, 15G, and 15B provided on the glass substrate 13, a black matrix 16 disposed between adjacent pixels, and a backlight 17 At least.

The

color filters

15R, 15G, and 15B are provided corresponding to the pixel electrodes 12 (corresponding to the pixels), for example, the color filter 15R is red, the color filter 15G is green, and the color filter 15B is blue. . In the present embodiment, one display pixel is constituted by three pixels, and

color filters

15R, 15G, and 15B are provided corresponding to the three pixels constituting the display pixel. In the horizontal direction of the display panel 1,

color filters

15R, 15G, and 15B are provided in this order. However, the arrangement order of the

color filters

15R, 15G, and 15B is not limited to this order. Further, the color of the color filter is not limited to three colors, and may be four colors of red, green, blue, and yellow, for example.

The black matrix 16 is a light blocking member that blocks light, and has a lattice shape as a whole. That is, a plurality of black matrices 16 extending in the horizontal direction of the display panel 1 are arranged in the vertical direction, and a plurality of black matrices 16 extending in the vertical direction are arranged in the horizontal direction. Although the black matrix 16 is disposed between adjacent pixels, in the present embodiment, between adjacent pixels is not only a region between adjacent pixel electrodes 12 but also a pixel electrode 12 is disposed. Part areas are also included. As will be described later, in both the horizontal direction and the vertical direction, the arrangement interval (pitch) between adjacent black matrices 16 is narrower than the arrangement interval (pitch) between adjacent pixels (adjacent pixel electrodes 12). The arrangement interval between the adjacent black matrices 16 is an interval between the center line of the black matrix 16 and the center line of the adjacent black matrix 16. The arrangement interval of adjacent pixels is a distance between the center line of a certain pixel and the center line of the adjacent pixel.

FIG. 2 is an enlarged view of the eyepiece 2. The eyepiece 2 has a function of enlarging an image displayed on the display panel 1. As the eyepiece 2, for example, the width H1 is 50 mm, the thickness H2 is 15 mm, the focal length (the focal length from the principal point to the focal point) is 45 mm, the radius of curvature of the lens on the display panel 1 side is 25 mm, and the opposite side to the display panel 1 A biconvex lens having a curvature radius of 200 mm can be used.

There are a total of two eyepieces 2 corresponding to the right eye and the left eye. The user views the right eye image displayed on the display panel 1 through the eyepiece lens 2 with the right eye and the left eye image with the left eye (views a side-by-side image) through the eyepiece 2 while wearing the head mounted display. An image can be visually recognized.

FIG. 3 is a diagram for explaining the arrangement position of the black matrix 16 in the display device 10 according to the present embodiment. FIG. 3 shows only the eyepiece 2 corresponding to the right eye among the two eyepieces 2.

In this embodiment, in order to prevent color crosstalk, the black matrix 16 is arranged so that light from the backlight 17 is not input to the user's eyes through the adjacent color filter for a certain pixel. In other words, the light emitted from the backlight 17 and transmitted through a certain target pixel (pixel electrode 12) to reach the user's eyes (viewpoint) is provided corresponding to the pixel adjacent to the target pixel. A black matrix 16 is disposed on the optical path of light passing through the color filter. In order to achieve such an arrangement, the black matrix 16 is arranged such that the arrangement interval between adjacent black matrices 16 is narrower than the arrangement interval between adjacent pixels (adjacent pixel electrodes 12). Color crosstalk is a phenomenon in which light from adjacent pixels passes through a color filter arranged corresponding to a certain pixel and reaches the user's eyes.

In the present embodiment, an optical path connecting the observation point and the end of the bus line 13 is specified as an optical path to which the light from the backlight 17 is input to the user's eyes through the adjacent color filter, and a black matrix is formed on the optical path. The black matrix 16 is arranged so that 16 is located. The end of the bus line 13 is an end on the opposite side (adjacent pixel side) to the target pixel among both ends (both ends) of the bus line 13 adjacent to the target pixel.

In the head mounted display, the position of the observation point is almost fixed. In FIG. 3, the width H3 of the observation point is also shown. The observation point width H3 is, for example, 10 mm.

For example, in FIG. 3, a pixel corresponding to the color filter 15Ga is a pixel of interest, and a pixel corresponding to the color filter 15Ra is an adjacent pixel. The optical path 31 in FIG. 3 is an optical path that reaches the one end of the observation point from the adjacent pixel through the color filter 15Ga, and the optical path 32 passes from the adjacent pixel through the color filter 15Ga to the other end of the observation point. Is the optical path to reach The black matrix 16a provided between the target pixel and the adjacent pixel is disposed so as to be positioned on the optical path 31 and the optical path 32. By providing the black matrix 16a on the

optical paths

31 and 32, it is possible to prevent light from adjacent pixels from reaching the user's eyes through the color filter 15Ga corresponding to the target pixel.

However, in the present embodiment, it is not configured to prevent the occurrence of color crosstalk by simply increasing the width of the black matrix 16. As illustrated in FIG. 4, the black matrix 16 is arranged at a position shifted in a direction toward the center line of the eyepiece 2 with respect to the center line between adjacent pixels. That is, it can be said that the black matrix 16 is arranged at a position shifted in the direction of the viewpoint with respect to the center line between adjacent pixels. The amount of deviation with respect to the center line between adjacent pixels increases as the position is farther from the viewpoint.

FIG. 4 is a diagram showing the relationship between the position of the black matrix 16 in the display device 10 of the present embodiment and the position of the black matrix 16p in the conventional display device. In the conventional display device, the black matrix 16p is provided between adjacent pixels so that the center line between the pixels matches the center line of the black matrix 16p. In this case, in the conventional display device, the arrangement interval S3 of the adjacent black matrix 16p is equal to the arrangement interval S2 of the adjacent pixels of the display panel 1. Further, in order to suppress the occurrence of color crosstalk, it is necessary to make the black matrix 16p thick to some extent.

On the other hand, in the display device 10 of the present embodiment, in order to suppress the occurrence of color crosstalk, with respect to the arrangement position of the conventional black matrix 16p (position based on the center line between adjacent pixels). For each of the left and right eyepieces 2, the black matrix 16 is arranged at a position shifted in a direction toward the center line of the eyepiece 2 (direction indicated by a thick arrow in FIG. 4). Since color crosstalk is more likely to occur in pixels farther from the center line of the eyepiece lens 2, when the arrangement position of the conventional black matrix 16 p is used as a reference, the farther from the centerline of the eyepiece lens 2, The amount of deviation increases. In other words, the closer the distance from the center line of the eyepiece lens 2 is, the wider the distance between adjacent black matrices 16 is. The farther the distance from the center line of the eyepiece lens 2 is, the narrower the distance between adjacent black matrices 16 is. In FIG. 4, the disposition interval S1 between the adjacent black matrices 16 at a position far from the center line of the eyepiece 2 is narrower than the disposition interval S2 between adjacent pixels.

In the head mounted display, since the display panel 1 is provided in the housing, the display panel 1 is not exposed to external light. Therefore, even if the position of the black matrix 16 is shifted, a malfunction of a TFT (Thin Film Transistor) due to photoconduction caused by external light or color mixture due to reflection of the external light on the bus line does not occur.

The aperture ratio for each pixel differs by disposing the black matrix 16 in a position different from the position of the black matrix 16p of the conventional display device. However, since the difference in aperture ratio between adjacent pixels is minute, there is almost no effect on white balance and the luminance difference is also slight. In order to compensate for the difference in aperture ratio between the pixels corresponding to the

color filters

15R, 15G, and 15B, the gradation values of the pixels corresponding to the

color filters

15R, 15G, and 15B are adjusted according to the aperture ratio. You may make it do.

FIG. 5 is a diagram showing the angle of light entering the eyepiece 2 from the outermost peripheral pixel of the display panel 1. In the present embodiment, the angle θ1 is 45 degrees, for example, and the angle θ2 is 80 degrees, for example.

FIG. 6 is a diagram showing the arrangement position of the black matrix 16 at the position of the outermost peripheral pixel of the display panel 1. In FIG. 6, the color filter of the outermost peripheral pixel of the display panel 1 is the color filter 15B, and the color filter of the pixel adjacent to the outermost peripheral pixel is the color filter 15G. If the black matrix 16 is present on the optical path of the angle θ1 passing through the color filter 15B of the adjacent pixel in the outermost peripheral pixel having the shallowest angle among the light entering the eyepiece 2, color crosstalk is suppressed. can do.

In this embodiment, when the line width of the bus line 13 is 3 μm and the angle θ1 is 45 degrees, the line width of the black matrix 15 is set to 7 μm, for example, and is shifted by 1.5 μm in the direction of the center line of the eyepiece 2. The occurrence of color crosstalk can be prevented. In the conventional direct-view display device, for example, when the bus line 13 has a line width of 3 μm, the black matrix has a line width of 10 μm in order to prevent the occurrence of color crosstalk at all viewing angles. There was a need. That is, according to the display device 10 of this embodiment, the line width of the black matrix 16 can be reduced by 30%, and the aperture ratio can be significantly improved. Thereby, the image quality of the display image can be improved.

FIG. 7 is a diagram for explaining a difference in position and line width between the black matrix 16 of the display device 10 in the present embodiment and the black matrix 16p of the conventional display device. In FIG. 7, the X-axis direction (horizontal direction) is the direction in which the scanning line extends, and the Y-axis direction (vertical direction) is the direction in which the data line extends. However, the X-axis direction may be the direction in which the data line extends, and the Y-axis direction may be the direction in which the scanning line extends.

In the conventional display device, the black matrix 16p is arranged at equal intervals. On the other hand, in the display device 10 according to the present embodiment, as described above, the black matrix is located at a position shifted in the direction toward the center line of the eyepiece 2 with reference to the position of the black matrix 16p of the conventional display device. 16 is arranged. In the present embodiment, as shown in FIG. 7, with reference to the position of the conventional black matrix 16p, in both the X-axis direction and the Y-axis direction, the position is shifted in the direction toward the center line of the eyepiece lens 2. A black matrix 16 is arranged. The amount of displacement increases as the distance from the center line of the eyepiece 2 increases in both the X-axis direction and the Y-axis direction. In addition, the line width of the black matrix 16 is narrower in the display device 10 of the present embodiment than in the black matrix of the conventional display device.

As described above, according to the display device 10 of the present embodiment, the occurrence of color crosstalk can be suppressed. Further, by disposing the position of the black matrix 16 with respect to the position of the conventional black matrix 16p, it is possible to suppress the influence of display defects caused by abnormal alignment of liquid crystals that occur between adjacent pixels. Thereby, a high quality image can be displayed.

[Second Embodiment]
In the display device 10 according to the first embodiment, the black matrix 16 is arranged at a position shifted in the direction toward the center line of the eyepiece 2 with reference to the position of the black matrix 16p of the conventional display device. As described above, as the distance from the center line of the eyepiece 2 increases, the amount of deviation of the black matrix 16 from the position of the black matrix 16p of the conventional display device increases. For this reason, the aperture ratio of the pixel far from the center line of the eyepiece lens 2 is lower than that of the pixel near the centerline of the eyepiece lens 2.

In the display device 10A according to the second embodiment, the closer the distance from the center line of the eyepiece lens 2 is, the wider the line width of the black matrix 16 and the equal the aperture ratio of each pixel. That is, since the arrangement interval of the adjacent black matrix 16 is wider as it is closer to the center line of the eyepiece lens 2, the line width of the black matrix 16 at the position where the arrangement interval of the adjacent black matrix 16 is wide is set to be equal to that of the adjacent black matrix 16. It is made wider than the line width of the black matrix 16 at a position where the arrangement interval is narrow.

FIG. 8 is a diagram for explaining a difference in position and line width between the black matrix 16 of the display device 10A in the second embodiment and the black matrix 16p of the conventional display device. Also in the present embodiment, as in the first embodiment, the position of the black matrix 16p of the conventional display device is used as a reference, and both the X-axis direction and the Y-axis direction are shifted in the direction toward the center line of the eyepiece lens 2. The black matrix 16 is arranged at the position. In both the X-axis direction and the Y-axis direction, as the distance from the center line of the eyepiece 2 increases, the amount of deviation of the black matrix 16 from the position of the black matrix 16p of the conventional display device increases.

The line width of the black matrix 16 of this embodiment is thicker as it is closer to the center line of the eyepiece lens 2 in both the X-axis direction and the Y-axis direction, and is thinner as it is farther from the centerline of the eyepiece lens 2. That is, as the distance from the center line of the eyepiece lens 2 becomes closer to the line width of the black matrix 16 positioned on the outermost side of the liquid crystal panel 1, the line width of the black matrix 16 gradually increases. Here, it is assumed that the line width of the black matrix 16 located on the outermost side of the display panel 1, that is, the line width of the thinnest black matrix 16 is equal to the line width of the black matrix 16 in the first embodiment.

With such a configuration, the aperture ratios of all the pixels can be made equal, so that a higher quality image can be displayed. In the example shown in FIG. 8, the aperture ratio of the pixel 21 close to the horizontal centerline and the vertical centerline of the eyepiece 2, and the position away from the horizontal centerline and the vertical centerline of the eyepiece 2. The aperture ratios of the pixels 22 are equal.

[Third Embodiment]
In the display device 10 according to the first embodiment, the black matrix 16 adjacent to each other in the horizontal direction (X-axis direction) and the vertical direction (Y-axis direction) of the display panel 1 is larger than the arrangement interval of adjacent pixels. The arrangement interval is narrow. In the display device 10B according to the third embodiment, the arrangement interval of adjacent black matrices 16 is narrower than the arrangement interval of adjacent pixels in one of the horizontal direction and the vertical direction of the display panel 1.

Here, in the direction in which the

color filters

15R, 15G, and 15B of different colors are arranged, that is, in the horizontal direction of the display panel 1, the arrangement interval of the adjacent black matrix 16 is narrower than the arrangement interval of the adjacent pixels. Will be described.

FIG. 9 is a diagram for explaining a difference in position and line width between the black matrix 16 of the display device 10B in the third embodiment and the black matrix 16p of the conventional display device. As shown in FIG. 9, when the position of the black matrix 16p of the conventional display device is used as a reference, in the display device 10B according to the present embodiment, in the horizontal direction (X-axis direction), the horizontal center line of the eyepiece lens 2 is displayed. The black matrix 16 is arranged at a position shifted in the direction of heading. With the position of the black matrix 16p of the conventional display device as a reference, the shift amount of the black matrix 16 increases as the distance from the center line of the eyepiece 2 in the horizontal direction increases. The line width of the black matrix 16 adjacent in the horizontal direction (extending in the vertical direction) is narrower than the line width of the black matrix 16p of the conventional display device.

On the other hand, in the vertical direction, it is the same as the position of the black matrix 16p of the conventional display device. That is, in the vertical direction, the arrangement interval between the pixels of the display panel 1 and the arrangement interval of the black matrix 16 are the same. The line width of the black matrix 16 adjacent in the vertical direction (extending in the horizontal direction) is the same as the line width of the black matrix 16p of the conventional display device.

As in the present embodiment, in the direction in which the

color filters

15R, 15G, and 15B having different colors are arranged, the arrangement interval of the black matrix 16 is made shorter than the arrangement interval between the pixels of the display panel 1. Crosstalk can be suppressed. In addition, in the direction in which the

color filters

15R, 15G, and 15B having different colors are arranged, it is possible to suppress the influence of display defects caused by the abnormal alignment of the liquid crystal that occurs between adjacent pixels. Thereby, a high quality image can be displayed.

In the above description, in the direction in which the

color filters

15R, 15G, and 15B having different colors are arranged, that is, in the horizontal direction of the display panel 1, the arrangement of the adjacent black matrix 16 is larger than the arrangement interval of the adjacent pixels. The interval was narrow. However, in the vertical direction (Y-axis direction) orthogonal to the direction in which the

color filters

15R, 15G, and 15B of different colors are arranged (X-axis direction), the adjacent black matrix 16 has a larger interval than the arrangement interval of adjacent pixels. A configuration in which the arrangement interval is narrow may be employed. In this case, in the vertical direction, it is possible to suppress the influence of display defects caused by the abnormal alignment of the liquid crystal that occurs between adjacent pixels.

[Fourth Embodiment]
In the display device 10B according to the third embodiment, the arrangement interval of the adjacent black matrix 16 is narrower than the arrangement interval of the adjacent pixels in one of the horizontal direction and the vertical direction of the display panel 1. The line widths of the black matrix 16 are all equal in the same direction in both the horizontal direction and the vertical direction. As described above, in the direction in which the arrangement interval of the black matrix 16 is narrower than the arrangement interval between the pixels of the display panel 1, the displacement amount of the black matrix 16 increases as the distance from the center line of the eyepiece 2 increases. Compared with the pixels near the center line of 2, the aperture ratio of the pixels far from the center line of the eyepiece 2 is low.

In the display device 10C according to the fourth embodiment, the arrangement interval of the black matrix 16 is shorter than the interval between the pixels of the display panel 1 in one of the horizontal direction and the vertical direction of the display panel 1, and In one direction, the closer the distance from the center line of the eyepiece lens 2 is, the wider the line width of the black matrix 16 and the equal the aperture ratio of each pixel.

Here, in the direction in which the

color filters

FIG. 10 is a diagram for explaining a difference in position and line width between the black matrix 16 of the display device 10C in the fourth embodiment and the black matrix 16p of the conventional display device. In the present embodiment, the black matrix 16 is arranged at a position shifted in the direction toward the center line of the eyepiece lens 2 in the horizontal direction with reference to the position of the black matrix 16p of the conventional display device. The farther from the center line of the eyepiece lens 2 in the horizontal direction, the more the black matrix 16 is displaced from the position of the black matrix 16p of the conventional display device.

In the horizontal direction, the line width of the black matrix 16 of this embodiment is thicker as it is closer to the center line of the eyepiece lens 2 and is thinner as it is farther from the centerline of the eyepiece lens 2. That is, in the horizontal direction, the line width of the black matrix 16 is gradually increased as the distance from the center line of the eyepiece lens 2 becomes shorter than the line width of the black matrix 16 positioned on the outermost side of the liquid crystal panel 1. Become. Here, it is assumed that the line width of the black matrix 16 located on the outermost side of the display panel 1, that is, the thinnest line width of the black matrix 16 is equal to the line width of the black matrix 16 in the first embodiment.

With this configuration, the aperture ratios of all the pixels can be made equal. In the example shown in FIG. 10, the aperture ratio of the pixel 101 close to the horizontal centerline and the vertical centerline of the eyepiece 2, and the position away from the horizontal centerline and the vertical centerline of the eyepiece 2. The aperture ratios of the pixels 102 are equal.

In the above description, in the direction in which the

color filters

15R, 15G, and 15B of different colors are arranged (X-axis direction), the adjacent black matrix 16 has a larger interval than the arrangement interval of adjacent pixels. A configuration in which the arrangement interval is narrow may be employed. In this case, the line width of the black matrix 16 may be narrower as it is closer to the center line of the eyepiece lens 2 in the vertical direction and thinner as it is farther from the center line of the eyepiece lens 2.

[Fifth Embodiment]
The display device 10D in the fifth embodiment is an in-vehicle display device. The in-vehicle display device is a display device used for a car navigation system, for example. As the display device 10D, the display panel 1 described in the first to fourth embodiments can be used.
