In this surface light source device, light is incident from a plurality of point light sources 2 arranged on a one side end surface of a light guide plate 1, is reflected on a light reflecting surface 11 on a rear surface of the light guide plate 1, and is emitted from a front surface of the light guide plate 1. The point light sources 2 comprise white light emitting diode elements. Two white light emitting diode elements out of six of the white light emitting diode elements having chromaticity outermost from a center of an aimed chromaticity range in opposite hue directions are arranged in an approximately center of a group of the white diode elements. |
