ABSTRACT:
Light emitted from a light source and incident on a light distributor of a light guide plate is partially emitted from the light guide plate as it is, and is predominantly reflected toward a prism section. Light incident on the prism section from the light distributor and light incident on the prism section directly from the light source are refracted and reflected by the prism section, and are then emitted from a light emission plane of the light guide plate in a region away from the light source in which the light distributor is not disposed, in a direction perpendicular to the light emission plane and substantially away from light source.
