Abstract:
A group III nitride compound semiconductor light-emitting element formed of Group III nitride compound semiconductor layers, comprising:a multi-layer comprising a plurality of light-emitting layers; a p-type semiconductor layer; and an n-type semiconductor layer, wherein the multi-layer comprises: a multiple quantum barrier-well layer comprising: a plurality of quantum-barrier-formation barrier layers comprising a Group III nitride compound semiconductor; and a plurality of quantum-barrier-formation well layers comprising a Group III nitride compound semiconductor, the barrier layers and the well layers being formed alternately and cyclically; and a plurality of low-energy-band-gap layers which emit light of different wavelengths, the multiple quantum barrier-well layer being provided between the low-energy-band-gap layers, and the multiple quantum barrier-well layer not emitting light.
