摘要:
A planar light source of the present invention has three lamps along a side face of a rectangular light guide plate. The lamps are arranged along an incidence plane which is one side plane of the light guide plate. The three lamps are arranged so as to be kept apart from each other at a given interval, and two lamps are arranged in close proximity to the incidence plane that is one side plane of the light guide plate. One lamp is arranged away from the incidence plane that is one side plane of the light guide plate with respect to the two lamps. A lamp reflector is formed continuously so as to become close to the three lamps and surround the respective three lamps, and assumes a substantially convex cross-sectional shape.
