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.

Claims (15)

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 a 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, having a through-hole, provided at least a display region of each pixel, wherein,

a light shielding region is formed surrounding the display region in each of the pixels, and

a width of the through-hole in a second direction changes in a stepped manner according to the position in the first direction, the width of the through-hole in the second direction being maximized at a central portion in the first direction of each pixel and decreases gradually in a stepped manner towards end portions in the first direction of each pixel.

2. 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 a 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, having a through-hole, provided at at least a display region of each pixel,

wherein a light shielding region is formed surrounding the display region in each of the pixels,

within each pixel, a width of the through-hole in the first direction is larger than a width of the display region, and a portion of the through-hole overlaps the light shielding region,

a width of the through-hole in a second direction orthogonal to the first direction at a display plane of the display panel changes gradually according to the position in the first direction, the width of the through-hole in the second direction being maximized at a central portion in the first direction of each pixel and decreases gradually in the direction toward end portions in the first direction of each pixel, and

the width of the through-hole in the second direction is minimized at a portion on the light shielding region,

wherein the position in the second direction of the through-hole in each pixel is the same among pixels adjacent to each other in the first direction.
