Patent ID: 8749722

Claim:
A display device, comprising: a planar light source for emitting light in a plane via a concavo-convex structure on a surface or interior thereof; a display panel, disposed in front of said planar light source, in which a plurality of display units that includes at least pixels for displaying an image for a first viewpoint and pixels for displaying an image for a second viewpoint is arranged in a matrix, said display panel emitting the light incident from said planar light source; an anisotropic scattering part, disposed in front of said display panel, for scattering light incident from said display panel so that scattering in a second direction is more significant than scattering in a first direction, said second direction being orthogonal to said first direction; and an image allocation part, disposed in front of said anisotropic scattering part, for allocating light incident from said anisotropic scattering part to different directions along said first direction in which pixels for displaying an image for said first viewpoint and pixels for displaying an image for said second viewpoint are arranged in said display units, wherein a direction of maximum scattering by said anisotropic scattering part is said second direction, wherein the anisotropic scattering part has a transparent sheet, and a plurality of convex parts or a plurality of concave parts on a surface of the transparent sheet and extending in the first direction, the plurality of convex parts or the plurality of concave parts each having a different length in the first direction and each having a different width in the second direction, and wherein the anisotropic scattering part reduces unevenness of the emitted light caused by the concavo-convex structure.
