Light emitting device, method of manufacturing the same, light emitting device package, and lighting system

摘要

A light emitting device includes a light emitting stack structure including a first conductive semiconductor layer (30), a second conductive semiconductor layer (50), and an active layer (40) between the first and second conductive semiconductor layers; a passivation layer (70) at least partially on the light emitting stack structure; a first electrode (91) on the first conductive semiconductor layer; and a second electrode (92) on the first electrode and the passivation layer.
