摘要:

Embodiments relate to a light emitting device, a method of manufacturing a light emitting device, a light emitting device package, and a lighting system. A light emitting device according to an embodiment includes: a first conductive semiconductor layer; an active layer on the first conductive semiconductor layer; an AlxGayIn1-x-yAn Nlayer (where 0 < x ≦ 1 and 0 ≦ y ≦ 1) (122); an Nlayer (where 0 < x ≦ 1 and 0 ≦ y ≦ 1) (122); an AlxGayIn1-x-yUndoped Al on NlayerpGa1-pN layer (where 0 ≦ p < 1) (124); and n layer (where 0 ≦ p < 1) (where 0 ≦ p < 1) and said undoped AlpGa1-pAnd a second conductivity-type semiconductor layer on the Nlayer.
