ABSTRACT:
A light emitting element has: a light emitting layer of semiconductor; and a diffusion layer that has a refractive index equal to or greater than that of the light emitting layer and that diffuses light emitted from the light emitting layer to increase the external radiation efficiency of the light emitting element. The light emitting layer has a refractive index equal to or greater than that of any layers formed between the light emitting layer and the diffusion layer.
