Disclosed is a light emitting structure comprising a first semiconductor layer, a second semiconductor layer, and an active layer disposed on between the first and second semiconductor layers, a first electrode electrically connected to the first semiconductor layer and a second electrode electrically connected to the second semiconductor layer. The first semiconductor layer is formed, at an edge portion thereof, with a hole, in which a portion of the first electrode is arranged.

Light emitting device

Provided are a light emitting device, a light emitting device package, and a lighting system. The light emitting device includes a crystalline substrate having a plurality of side surfaces, a light emitting structure layer comprising a first conductive type semiconductor layer, an active layer, and a second conductive type semiconductor layer on the substrate, and a first electrode on the first conductive type semiconductor layer and a second electrode on the second conductive type semiconductor layer. An amorphous region is defined in a side surface of the substrate, and the amorphous regions of two sides adjacent to each other have different depths from a top surface of the substrate.

Light emitting device, light emitting device package, and lighting system

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.
