ABSTRACT:
A light guiding plate includes: an X axis direction light distribution control section; and a diffuse reflection section. The X axis direction light distribution control section performs light distribution control by which the incident light is deflected such that a tilt of an X axis direction with respect to a normal direction approaches to zero, and outputted from the light emitting surface. A direction of the incident light is the X axis direction, a direction orthogonal to the X axis direction and parallel to the light emitting surface is a Y axis direction, and a direction vertical to the X axis direction and the Y axis direction is the normal direction. The diffuse reflection section reflects the guided incident light from the light incident surface to diffuse in the Y axis direction inside of the light guiding plate and guides to the X axis direction light distribution control section.
