PLANAR LIGHT SOURCE APPARATUS

摘要

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.

1. A planar light source apparatus comprising:
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, wherein the frame body has a plurality of projection portions on an inner side of the frame body, wherein the light source is arranged between the projection portions, wherein the frame body, the mounting substrate, and the light guide plate are fixed via a fixing member, wherein the light source has a pair of electrode terminals, wherein the mounting substrate has a land portion on which the electrode terminals are mounted, wherein connection portions are provided by which the electrode terminals and the land portion are electrically connected, wherein the projection portions have a thickness defined by a surface on the mounting substrate side and an opposite surface relative thereto, and wherein each of the projection portions is formed such that, in a cross-section of at least a portion of the projection portion viewed in a projecting direction of the projection portion in a vicinity of the connection portions, the height or the width of the projection portion is smaller than the highest height or the highest width of the projection portion from the surface of the projection portion on the mounting substrate side toward the opposite surface.
