ABSTRACT:
A planar light source device includes a light source section having a plurality of light emitting diodes as a light source, and a light guiding plate guiding light from the light source section to emit planar light. The light emitting diodes being turned off detect the quantities of light from the other light emitting diodes, and adjust the quantities of light emission of the other light emitting diodes based on the detected quantities of light.
