Abstract:
A light emitting element comprises a first n-side semiconductor layer, a first active layer having a first well layer containing indium, a first p-side semiconductor layer, a second n-side semiconductor layer in contact with the first p-side semiconductor layer, a second active layer having a second well layer containing indium, and a second p-side semiconductor, each formed of a nitride semiconductor. The second active layer has a first intermediate layer positioned closer to the first active layer than is the second well layer and containing indium. An indium composition ratio of the first well layer is less than an indium composition ratio of the second well layer. An indium composition ratio of the first intermediate layer is less than an indium composition ratio of the first well layer. A thickness of the first intermediate layer is less than a thickness of the second well layer.
