Abstract:
1. A liquid crystal display device comprising: a liquid crystal panel; two polarizing layers provided so as to sandwich the liquid crystal panel; a light source; a lens layer for converging light emitted from the light source; and a λ/2 layer, one of the two polarizing layers being disposed closer to the light source being a rear polarizing layer, the lens layer being disposed between the rear polarizing layer and the light source, the λ/2 layer being disposed between the rear polarizing layer and the lens layer; wherein a transmission axis of the polarizing layer closest to a viewer is aligned in a vertical direction; wherein the light source is provided behind the lens layer; wherein the lens layer has a plurality of valleys formed thereon in such a manner that each of the valleys runs parallel to each other and crosses the lens layer, and wherein the valleys are formed along a horizontal direction as seen from an observer of the liquid crystal panel.
