| titleOfInvention | Light emitting device and lighting system having the same |
| abstract | The light emitting device according to an embodiment includes a substrate, a first conductive type semiconductor layer on the substrate, an active layer including a well layer and a barrier layer on the first conductive type semiconductor layer, Wherein the barrier layer comprises a first barrier layer comprising indium, a second barrier layer and a third barrier layer having different contents of aluminum on the first barrier layer, A first barrier protrusion disposed between the first barrier layer and the second barrier layer, and a second barrier protrusion disposed between the second barrier layer and the third barrier layer. The embodiment has the effect of preventing overshooting of carriers passing through the well layer / barrier layer by forming the well layer and the barrier layer to have different In and Al contents. |
