ABSTRACT:
A planar light source device comprises a light guide having a light entrance surface through which light enters, and a light exit surface, from which the light that entered through the light entrance surface exits, a light source disposed along the light entrance surface, and a reflecting body, which has two ends forming an opening to discharge the light emitted from the light source and sandwiching the light guide in a thickness direction, surrounds the light source, and reflects the light emitted from the light source toward the light entrance surface. The light exit surface has a grained surface region where a convex dot pattern is formed and a positioning region where no dot pattern is formed. One of the two ends of the reflecting body, which is brought into contact with the light exit surface, has an edge that is positioned in the positioning region.
