Abstract
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.
