Abstract
A planar light source apparatus has a light guide plate, a light source arranged on a side face of the light guide plate, a mounting substrate on which the light source is mounted, and a frame body that holds the light guide plate. The frame body has a plurality of projection portions on an inner side of the frame body. The light source is arranged between the projection portions. The frame body, the mounting substrate, and the light guide plate are fixed via a fixing member. The light source has a pair of electrode terminals. The mounting substrate has a land portion on which the electrode terminals are mounted. Connection portions are provided by which the electrode terminals and the land portion are electrically connected. The projection portions have a thickness defined by a surface on the mounting substrate side and an opposite surface relative thereto.
