Abstract
A light source device includes: a light source section; a light guide plate; and a supporting member supporting the light source section so as to oppose a peripheral surface of the light guide plate. The light source section includes light sources and a light source substrate having a surface on which the light sources are mounted. The supporting member has an opposed surface opposing a rear surface of the light guide plate. The opposed surface has receptacles to allow the light source section to be attached so that the surface of the light source substrate opposes one end surface of the light guide plate. The receptacles are arranged so that the light source section can be attached to a selected receptacle, resulting in different separation distances between the light source section and the one end surface of the light guide plate.
