A planar light source device includes a light guide plate, a lamp unit and emitting light to a side surface of the light guide plate, a rear frame for storing the light guide plate and the lamp unit and a mold frame in frame shape disposed between the light guide plate and the rear frame for fitting with the light guide plate provided with a positioning part. In the positioning part, the light guide plate has a surface almost parallel to a side surface provided with the positioning part and a connection surface for connecting the parallel surface with the side surface provided with the positioning part. The rear frame supports the light guide plate with the mold frame interposed therebetween, and includes a projecting part projected inside and formed of an end edge surface and a side edge surface, the end edge surface being disposed to oppose the side surface provided with the positioning part of the light guide plate and the side edge surface being disposed to oppose the connection surface.
