Patent ID: 8582042

Claim:
A stereoscopic image display apparatus comprising: a display device comprising a plurality of subpixels arranged in a first direction and a second direction perpendicular to the first direction to form a matrix, each subpixel having an aperture provided with a color component; and an optical controller provided to be opposed to the display device and having a plurality of rectilinear optical apertures extending in the second direction, the plurality of rectilinear optical apertures being arranged in the first direction, wherein the apertures in the subpixels adjacent to each other in the first direction have a nonoverlapping region in the second direction and wherein a ratio of a length in the second direction of the aperture to a length in the second direction of the subpixel is substantially constant along the first direction, and wherein the aperture has a shape which is linear-symmetric with respect to a symmetry axis parallel to the first direction and which has an odd number of sets of sides having same inclination.
