In this surface light source device, light is incident from a plurality of point light sources arranged on a one side end surface of a light guide plate is reflected on a light reflecting surface on a rear surface of the light guide plate and is emitted from a front surface of the light guide plate The point light sources 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.

Surface light source device and adjusting method of chromaticity thereof
