ABSTRACT:
A planar light-source device is obtained in which, in the space between a point light source and the peripheral portion of a through-hole in a case, rays that leak into or are absorbed into a space outside a hollow region can be reduced, whereby the number of rays that propagate into the hollow region can be increased. A point light source is installed from outside a case, through through-holes formed in the case and a reflection sheet, and a reflector formed on the reflection sheet to correspond to the point light source is slanted with respect to the bottom side of the case, depthward along the through-hole, in a region enclosed by the peripheral portion of the through-hole of the case and by the point light source.
