Light emitting device and light emitting device package having the same

摘要

Disclosed are a light emitting device and a light emitting device package. The light emitting device includes a light emitting structure (100) including a first conductive type semiconductor layer (110), a second conductive type semiconductor layer (130), and an active layer (120) between the first conductive type semiconductor layer and the second conductive type semiconductor layer, an electrode (115) on the first conductive type semiconductor layer, a reflective layer (150) under the second conductive type semiconductor layer, a protective layer (140) at outer peripheral portions (DI) of a lower surface of the second conductive type semiconductor layer, and a light extraction structure (132) including a compound semiconductor on the protective layer.
