Abstract
A light emitting element includes: a first semiconductor layer including a semiconductor of a first type; a second semiconductor layer including a semiconductor of a second type different from the first type; and an active layer between the first and second semiconductor layers, the active layer including a first active area including a first well layer, and a second active area including a second well layer. The first well layer has a first band gap, and the second well layer has a second band gap smaller than the first band gap. At least a portion of the first active area is between the second active area and the second semiconductor layer. A distance between the second active area and the second semiconductor layer is equal to or greater than 0.1 times of a distance between the first and second semiconductor layers.
