Abstract
A planar light source device includes: a plurality of point light sources, each of which emits a light; a light guide plate that includes a first surface, and a second surface perpendicular to the first surface, and that is configured to guide the emitted lights incident from the first surface to be emitted from the second surface; a bottom case including a side portion substantially parallel to the first surface; a light source substrate that includes the plurality of point light sources arranged thereon at a predetermined interval, and that is arranged at a side of the first surface; a frame that sandwiches the light source substrate and the side portion of the bottom case and holds the second surface and that includes a plurality of gaps at positions facing the point light source.

A planar light source device comprising:
- a plurality of point light sources, each of which emits a light;
- a light guide plate including a first surface, and a second surface perpendicular to the first surface, the light guide plate being configured to guide the emitted lights incident from the first surface to be emitted from the second surface;
- a bottom case including a side portion substantially parallel to the first surface;
- a light source substrate including the plurality of point light sources arranged thereon at a predetermined interval, the light source substrate being arranged at a side of the first surface;
- and
- a frame that clamps, from opposite directions, the light source substrate and the side portion of the bottom case, and includes
- a projection extending over and contacting the second surface, and
- a plurality of gaps at positions facing the point light sources.
