Disclosed is a light-emitting device including a substrate (110), a light-emitting structure (115) on the substrate, the light-emitting structure including a first semiconductor layer (120), an active layer (130) and a second semiconductor layer (140), a light-transmitting electrode layer (150) on the second semiconductor layer, and a first reflective layer (161) on the light-transmitting electrode layer, wherein the first reflective layer comprises a first layer having a first index of refraction and a second layer having a second index of refraction different from the first index of refraction. Based on this configuration, it is possible to protect the light-emitting device and improve luminous efficiency thereof. |
