    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, and an insulating layer enclosing the first semiconductor layer, the active layer, and at least a portion of the second semiconductor layer. The first semiconductor layer, the active layer, and the second semiconductor layer are successively disposed in a first direction. The active layer includes a first barrier layer, a second barrier layer, and a first well layer disposed between the first barrier layer and the second barrier layer, and including a non-uniform indium composition ratio in a first direction and a second direction intersecting the first direction, and including a non-uniform indium density in a third direction intersecting the first direction and the second direction.

    Abstract: A display device includes a first electrode and a second electrode spaced apart from each other, and light emitting elements disposed between the first electrode and the second electrode. Each of the light emitting elements include a first semiconductor layer, a second semiconductor layer disposed on the first semiconductor layer, and an active layer disposed between the first semiconductor layer and the second semiconductor layer. Each of the light emitting elements emits light with a wavelength in a range of about 464 nm to about 468 nm at a current density in a range of about 0.5 A/cm2 to about 100 A/cm2, and has a maximum external quantum efficiency greater than or equal to about 15%.

    Abstract: A display device includes a first electrode and a second electrode, spaced apart from each other, and light emitting elements disposed between the first electrode and the second electrode. Each of the light emitting elements includes a first semiconductor layer, a second semiconductor layer disposed on the first semiconductor layer, and an active layer disposed between the first semiconductor layer and the second semiconductor layer. A thickness of the active layer is in a range of about 1 nm to about 2.8 nm, the active layer includes InGa1-xN (about 0.18≤x≤about 0.20). The light emitting elements emit light with a wavelength in a range of about 462 nm to about 472 nm in a current density in a range of about 0.5 A/cm2 to about 100 A/cm2.
