| description | A planar light source apparatus according to the present invention includes a light source, a holding substrate that holds the light source at a main surface, and a light-distribution control element that is disposed at the main surface of the holding substrate so as to cover the light source, and changes light distribution of light rays emitted from the light source. The light-distribution control element includes a diffusion part that is provided at at least at one surface of a plurality of surfaces that structure the outer shape of the light-distribution control element. The at least one surface where the diffusion part is provided is a surface different from an installation surface capable of abutting on the main surface of the holding substrate. |
