Patent ID: 8054548

Claim:
A three-dimensional image display device comprising: a display panel on which a plurality of pixels colored in a plurality of colors are arrayed in a first direction, and a second direction orthogonal to said first direction, in matrix fashion; and an optical unit for distributing light emitted from the pixels arrayed in said first direction into mutually different directions along said first direction, and also distributing light emitted from the pixels arrayed in said second direction into mutually different directions along said second direction, wherein the array pitch of said pixels in said first direction and the array pitch of said pixels in said second direction are equal to each other, said display panel is made up of a plurality of pixel matrixes wherein a plurality of pixels having the same color are mutually arrayed in matrix fashion, on which said pixel matrixes having mutually different colors are repeatedly arrayed in said first direction and in said second direction, and said optical unit is made up of a plurality of optical elements corresponding to said pixel matrixes, wherein in the event that said first direction is disposed so as to coordinate with the direction from the right eye of an observer to the left eye, a pair of pixels on which a right-eye image and left-eye image are respectively displayed arrayed in said first direction within each display unit, also a plurality of pixels on which mutually different images are displayed arrayed in said second direction within each display unit, and in the event that said second direction is disposed so as to coordinate with the direction from the right eye of an observer to the left eye, a pair of pixels on which a right-eye image and left-eye image are respectively displayed arrayed in said second direction within each display unit, also a plurality of pixels on which mutually different images are displayed arrayed in said first direction within each display unit.
