Abstract: A light guiding board allows introduction of light into an optically-transparent board member through an incidence surface. Prisms serve to irradiate the light out of the back surface of the optically-transparent board member. A surface emission is realized at the back surface of the optically-transparent board member. In the case where an uneven luminance is generated in the light emitted toward the incidence surface, a flat region is aligned with a dark region. The flat region serves to direct the light to the prisms. The light scatters at a position outside the flat region based on the action of a light scattering structure. A part of the scattered light is directed to the extension of the flat region. The light of a sufficient amount can be introduced into the prisms on the extension of the flat region.

The prismatic light-guide plate has scattering portions provided in a region of the emission surface that emits the emitted light at a high density, for scattering the emitted light and broadening an angle of view of light.
