| titleOfInvention | Light emitting device, and lighting system |
| abstract | The embodiment relates to a light emitting device, a method of manufacturing a light emitting device, a light emitting device package, and a lighting system. The light emitting device according to the embodiment includes a first conductivity type semiconductor layer; An active layer including a quantum well and a quantum wall on the first conductivity type semiconductor layer; A second conductivity type semiconductor layer on the active layer; And a first electrode and a second electrode electrically connected to the first conductivity type semiconductor layer and the second conductivity type semiconductor layer, respectively. The quantum well includes In x Al y Ga (1-xy) N (however, 0<x<1, 0≤y<1), and the composition of indium in the quantum well includes a region in which the composition of indium gradually decreases, The composition of aluminum may include a gradually increasing area. |
