Abstract
A light emitting element of the present disclosure includes a compound semiconductor substrate, a stacked structureincluding a GaN-based compound semiconductor, a first light reflection layer, and a second light reflection layer. The stacked structureincludes, in a stacked state a first compound semiconductor layer, an active layer, and a second compound semiconductor layer. The first light reflection layeris disposed on the compound semiconductor substrateand has a concave mirror section. The second light reflection layeris disposed on a second surface side of the second compound semiconductor layerand has a flat shape. The compound semiconductor substrateincludes a low impurity concentration compound semiconductor substrate or a semi-insulating compound semiconductor substrate.
