Abstract

The display device includes a display panel on which sub-pixel pairs are arranged in a lateral direction, and a parallax barrier shutter panel on which sub-openings that can be changed between a light transmittance state and a light-shielding state are arranged in a lateral direction. Arbitrary allocated number of adjacent sub-openings among the plural sub-openings belonging to a reference parallax barrier pitch are put into a light transmittance state, and the remaining sub-openings are put into a light-shielding state, so that a general opening is formed on the parallax barrier shutter panel. A sub-opening pitch of the sub-opening on the boundary part between the adjacent common driving areas is different from the sub-opening pitch of the other sub-openings.

First claim

What is claimed is:

1 . A display device that can simultaneously display left and right images, the device comprising:
a display panel on which a sub-pixel pair including two sub-pixels for displaying said left and right images, is arranged in a longitudinal direction and in a lateral direction; and an optical induction member having openings which are arranged in a vertical stripe, and guide light emitted from said sub-pixel displaying said left image and light emitted from said sub-pixel displaying said right image in different directions, wherein a first main color, a second main color, a third main color, and a fourth main color, decreasing the brightness in this order, are assigned on one-to-one basis to four sub-pixels in each row in said sub-pixels of a 4×4 matrix repetitively arranged in the longitudinal direction and in the lateral direction, one of said sub-pixels to which said third main color or said fourth main color is assigned is arranged between said sub-pixel to which said first main color is assigned and said sub-pixel to which said second main color is assigned, as for said four sub-pixels in each row, said sub-pixels in a first row to which said first main color and said second main color are assigned and said sub-pixels in a third row to which said second main color and said first main color are assigned are arranged on same lines, respectively, and said sub-pixels in a second row to which said first main color and said second main color are assigned and said sub-pixels in a fourth row to which said second main color and said first main color are assigned are arranged on same lines, respectively.

2 . The display device according to claim 1 , wherein
in said 4×4 sub-pixels in the matrix, said sub-pixels in the first row to which said third main color and said fourth main color are assigned and said sub-pixels in the third row to which said fourth main color and said third main color are assigned are arranged on same lines, respectively, and said sub-pixels in the second row to which said third main color and said fourth main color are assigned and said sub-pixels in the fourth row to which said fourth main color and said third main color are assigned are arranged on same lines, respectively.

3 . The display device according to claim 1 , wherein
said first main color is white.

4 . The display device according to claim 1 , wherein
said sub-pixels to which a plurality of said first main colors are assigned are obliquely arranged with respect to the lines and the rows of said sub-pixels, said sub-pixels to which said plurality of first main colors are assigned being adjacent to each other.

5 . The display device according to claim 3 , wherein
said sub-pixels to which a plurality of said first main colors are assigned are obliquely arranged with respect to the lines and the rows of said sub-pixels, said sub-pixels to which said plurality of first main colors are assigned being adjacent to each other.
