Abstract

A translucent liquid crystal display panel ( 2 ) includes pixel pairs as display units each formed by a left-eye pixel ( 4 L) and a right-eye pixel ( 4 R) and arranged in a matrix shape. A through hole ( 4 Ld) arranged in a color layer ( 4 Lc) of a color filter has a slit shape whose longitudinal direction is identical to the orientation direction of a cylindrical lens ( 3 a ) constituting a lenticular lens ( 3 ). Similarly, a through hole ( 4 Rd) arranged in a color layer ( 4 Rc) of a color filter has a slit shape whose longitudinal direction is identical to the orientation direction of the cylindrical lens ( 3 a ) constituting the lenticular lens ( 3 ). This suppresses the phenomenon that a hue is changed by a field-of-view angle and/or an external light condition on the translucent display panel capable of displaying an image directed to a plurality of viewpoints.

First claim

The invention claimed is:

1. A display panel comprising:
a plurality of display units including at least pixels for displaying a first viewpoint image and pixels for displaying a second viewpoint image arranged in the shape of a matrix;
an optical member, for splitting in mutually different directions light emitted from each pixel within the display unit provided along a first direction along which the pixels for displaying the first viewpoint image and the pixels for displaying the second viewpoint image are arranged; and
color filter layers each provided at least at a display region of each pixel, the color filter layers each being provided with a through-hole,
wherein each of the pixels for displaying the first viewpoint image and the pixels for displaying the second viewpoint image include the display region and a light shielding region that surrounds the display region and partitions the display region,
wherein relative positions of the through-holes in some pixels of the same viewpoint are different from relative positions of the through-holes in some other pixels of the same viewpoint, and
wherein the plurality of pixels for displaying the image for the same viewpoint include symmetrically-located pixels with respect to a line segment extending in a second direction, the second direction being orthogonal to the first direction on a display plane of the display panel.

2. The display panel according to claim 1 , wherein the pixels of the display panel exhibit a parallelogram shape, and pixels neighboring in the second direction have a line-symmetrical relationship with respect to the line segment extending from the second direction.

3. The display panel according to claim 1 , wherein the through-holes are arranged so that a total value for an opening width of the through-holes in the second direction is substantially constant when each through-hole is combined whilst retaining the relative positions thereof in the first direction, in each pixel neighboring in the second direction.

4. The display panel according to claim 1 , wherein the optical member does not have an image forming relationship with the pixels.

5. A display device comprising the display panel disclosed in claim 1 .

6. A terminal device comprising the display device disclosed in claim 5 .

7. The display panel according to claim 1 , wherein the relative position and shape of the through-holes occurring at each pixel have a line-symmetrical relationship with respect to a line segment extending in the second direction with regards to pixels neighboring the second direction.

8. A display panel comprising:
a plurality of display units including at least pixels for displaying a first viewpoint image and pixels for displaying a second viewpoint image arranged in the shape of a matrix;
an optical member, for splitting in mutually different directions light emitted from each pixel within the display unit provided along a first direction along which the pixels for displaying the first viewpoint image and the pixels for displaying the second viewpoint image are arranged; and
color filter layers each provided at least at a display region of each pixel, the color filter layers each being provided with a through-hole,
wherein each of the pixels for displaying the first viewpoint image and the pixels for displaying the second image include the display region and a light shielding region that surrounds the display region and partitions the display region, and
wherein the through-hole adopts a shape divided with respect to the first direction within each pixel, and relative positions of the through-holes in some pixels of the same viewpoint are different from relative positions of the through-holes in some other pixels of the same viewpoint.
