Abstract
A planar lighting device includes: a light guide plate; a plurality of light sources arranged in line along a longitudinal direction of a side end surface of the light guide plate, each of light sources including a pair of electrode terminals; and a mounting substrate on which the light sources are mounted, the mounting substrate including a conductive pattern including a plurality of pairs of lands to which the respective pairs of electrode terminals of the light sources are connected. The light sources are mounted such that, in a longitudinal direction of the light sources, a gap between an outer side of each of the pairs of electrode terminals and an outer side of corresponding one of the pairs of lands is smaller than a gap between an inner side of the pair of electrode terminals and an inner side of the corresponding pair of lands.
