Light-emitting device having excellent current spreading effect and method for manufacturing same

Abstract

Disclosed are a light-emitting device having excellent light-emitting efficiency by a current spreading effect and a method for manufacturing the same. The light-emitting device, according to the present invention, comprises: a light-emitting structure which is formed on a substrate, includes a first semiconductor layer, an active layer, and a second semiconductor layer, and in which a plurality of trenches are formed up to the second semiconductor layer and the active layer; a first electrode formed to come in contact with the second semiconductor layer of the light-emitting structure; and a second electrode formed to come in contact with the first semiconductor layer along at least one edge of the substrate.
