Disclosed is surface light source device that, despite using a plurality of point light sources, has almost no uneven luminescence (hot spots) in the vicinity of an incident light surface of a light guide plate and has uniform luminescence across almost the entire light-emitting surface of the light guide plate. Also disclosed is a television receiver that uses the surface light source device as a liquid crystal display device. The television receiver comprises: a surface light source device with a light guide plate that has a light-emitting surface, a facing surface that faces the light-emitting surface, and at least one incident light surface sandwiched between the light-emitting surface and the facing surface, and with a plurality of point light sources arranged in the vicinity of the at least one incident light surface in the light guide plate; a display panel arranged so as to face the light-emitting surface of the light guide plate, with a display area that displays by adjusting light transmission and a shielding frame that demarcates the display area; and a tuner that receives broadcast video signals. The at-least-one incident light surface in the light guide plate has a plurality of concave and convex sections that have openings or bottom surfaces with a long anistropic shape in a direction perpendicular to the light-emitting surface. |
