A flexible circuit board includes a plurality of first wires that have a first connection area and a first insulating layer that covers the first wires such that the first connection area is exposed. A printed circuit board includes a plurality of second wires that have a second connection area, a second insulating layer that covers the second wires such that the second connection area is exposed, and a plurality of island conductors adjacent to the second wires across a gap. The second connection area is covered with an anisotropic conductive layer. Each of the second wires in the second connection area at least partially faces a corresponding one of the wires in the first connection area across the anisotropic conductive layer. The plurality of island conductors include an island conductor that is in contact with the anisotropic conductive layer and partially exposed from the anisotropic conductive layer.

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.
