Light emitting device, light emitting device package and lighting system including the same

摘要

Provided are a light emitting diode (190), a light emitting diode package (200) and a lighting system (1100) including the same. The light emitting diode (LED) comprises a light emitting structure comprising a second conductive type semiconductor layer (140), an active layer (130), and a first conductive type semiconductor layer (120) and a first electrode (125) over the light emitting structure. A portion (110) of the light emitting structure is sloped at a predetermined angle.
