Abstract
Provided is an edge-light illuminating device capable of preventing formation of a gap between point light sources and edge faces of a light guide plate, and also capable of allowing heat expansion of the light guide plate. An edge-light illuminating device 1 for illuminating a liquid crystal panel from behind includes a rectangular-shaped light guide plate 2, a wall 3 surrounding the light guide plate, a plurality of holding members 4 disposed between edge faces 7 of the light guide plate and the wall and arranged to hold the light guide plate within the wall, and two rows 6 each consisting of point light sources 5 aligned along the edge faces 7a, 7b on two adjacent sides of the light guide plate, wherein some of the holding members, which are opposed to the point light sources while interposing the light guide plate therebetween, are elastic holding members 4a having elasticity.
