Abstract
A light emitting element includes: a first semiconductor layer; an active layer disposed on the first semiconductor layer; a second semiconductor layer disposed on the active layer; a third semiconductor layer comprising a third-first semiconductor layer and a third-second semiconductor layer stacked on the second semiconductor layer; and a fourth semiconductor layer disposed on the third-second semiconductor layer. The third semiconductor layer is a tunneling junction layer. A sum of a thickness of the fourth semiconductor layer and the third-second semiconductor layer is different from a sum of a thickness of the second semiconductor layer and the third-first semiconductor layer.
