Abstract
A light emitting element comprising a layered structure configured by layering a first light reflecting layerconfigured by layering a plurality of thin films, a light emitting structure, and a second light reflecting layerconfigured by layering a plurality of thin films, wherein the light emitting structureis configured by layering, from the first light reflecting layer side, a first compound semiconductor layer, an active layer, and a second compound semiconductor layer, a second electrodeand an intermediate layerare formed between the second compound semiconductor layerand the second light reflecting layerfrom the second compound semiconductor layer side, and the value of a surface roughness of a second surfaceof the intermediate layerin contact with the second light reflecting layeris less than the value of a surface roughness of a first surfaceof the intermediate layerfacing the second electrode
