Abstract
A light emitting element includes a laminated structure formed by laminating a first light reflecting layer, a light emitting structure, and a second light reflecting layer. The light emitting structureis formed by laminating, from the first light reflecting layer side, a first compound semiconductor layer, an active layer, and a second compound semiconductor layer. In the laminated structure, at least two light absorbing material layersare formed in parallel to a virtual plane occupied by the active layer
