Abstract
A light emitting element includes a light emitting element core including a first area and a second area surrounding the first area. The light emitting element core includes a first semiconductor layer doped with a first dopant, a second semiconductor layer disposed on the first semiconductor layer and doped with a second dopant, an element active layer disposed between the first semiconductor layer and the second semiconductor layer; and a third semiconductor layer disposed between the element active layer and the second semiconductor layer and doped with the second dopant. The second area of the light emitting element core is located on an outer circumference of the light emitting element core and includes an outer surface of the light emitting element core. A doping concentration of the second dopant of the third semiconductor layer is lower than a defect density of the second area of the light emitting element core.
