A light emitting device according to the embodiment includes a substrate (110); a buffer layer (115) over the substrate; an electrode (118) including a perforation pattern (119) through top and bottom surfaces of the electrode over the buffer layer; a first semiconductor layer (130) over the electrode; an active layer (140) over the first semiconductor layer; and a second semiconductor layer (150) over the active layer. The first semiconductor layer extends onto a top surface of the perforation pattern by passing through the perforation pattern while making contact with the buffer layer. |
