Abstract
Disclosed is a light emitting device including a light emitting structure including a first conductive-type semiconductor layer, a second conductive-type semiconductor layer and an active layer interposed between the first conductive-type semiconductor layer and the second conductive-type semiconductor layer, a first electrode layer electrically connected to the first conductive-type semiconductor layer, and a second electrode layer disposed on the second conductive-type semiconductor layer, wherein the second electrode layer includes a plurality of adhesive seeds spaced from one another on the light emitting structure, a reflective layer disposed on the plurality of adhesive seeds, and a protective layer disposed on the reflective layer, wherein the reflective layer contains silver (Ag) or an Ag alloy. As a result, it is possible to improve light reflectance and electrical properties of the electrode layer of the light emitting device and reliability of the electrode layer.
