It is an object to provide a technique capable of enhancing evenness of a planar light. A planar light source device includes a light source, a holding substrate, a light distribution control element having a light incident surface and a light outputting surface, a reflection part reflecting the light which has been reflected in an inner side of the light distribution control element toward the side of the display surface, and a case which houses the light source, the holding substrate, the light distribution control element, and the reflection part. A part opposite to the side of the display surface, in relation to at least the light distribution control element in a region between the light distribution control element and an inner wall of the case, is covered by the reflection part.
