PURPOSE: A light emitting device is provided to improve adhesion by using a first and a second electrode which have recessed pattern structures. CONSTITUTION: A first semiconductor layer, an active layer (130), and a second semiconductor layer are laminated. A first electrode (160) is formed on a preset region on the first semiconductor layer. A second electrode (170) is formed on a preset region on the second semiconductor layer. At least one area of the first and the second electrode is a recessed structure. The recessed structure exposes a part of the first semiconductor layer or the second semiconductor layer.
