Abstract: Adjustments during assembly of an illuminating unit having a conventional light pipe in order to position the light pipe and a light guide plate are laborious. Further, a minute prism group having a pitch on the order of 100 ?m must be provided to a side surface of the light pipe in order to uniformly guide illuminating light to the light guide plate. An illuminating unit of the present invention is provided with a light guide plate having an illuminating surface that is illuminated by light from a point light source, and a light pipe having an incident surface to which light from the point light source is made incident and an emerging portion from which the light emerges to the light guide plate. The emerging portion and the light guide plate are integrally joined.

Abstract: 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.
