摘要:
A surface emitting apparatus includes a light guide plate, a plurality of point light sources, a diffusing member, and a spacer member. The light guide plate has an end surface and a light emitting surface and is configured to allow light incident on the end surface to be emitted from the light emitting surface. The plurality of point light sources is provided to oppose the end surface of the light guide plate. The diffusing member is provided on a light emitting surface side of the light guide plate. The spacer member defines a space between the light emitting surface and the diffusing member such that a distance between the light emitting surface and the diffusing member is larger than a thickness of the light guide plate.
