Abstract:
A surface light source device comprising at least one light source, a transparent panel, a diffusing panel and a reflecting surface. This surface light source device is configured so that brightness is enhanced in a direction perpendicular to the diffusing panel by disposing, on the side of a front surface of the transparent panel, a transparent sheet which has protrusions having a saw-tooth-like sectional shape formed on one surface thereof.
