摘要:
A surface light source conversion member, which converts emission light from a light source to planar light, has a predetermined thickness at a part thereof where a light incidence surface of a light guide, which is opposed to the light source, is located. A reflector, which reflects emission light from the light source toward the light incidence surface, includes a clamp portion that clamps the surface light source conversion member in a thickness direction thereof. The clamp portion contacts a corner portion that is formed between a light emission surface of the light guide and the light incidence surface of the light guide and is separated from the light emission surface. The reflector creates a gap, which is smaller than a predetermined thickness, between the light source and the light incidence surface.
