Beschreibung
Zusammenfassung:	Provided are a light emitting diode, a light emitting diode package, and a lighting system. The light emitting diode includes a crystalline substrate (10) having a plurality of side surfaces (11-14), 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 (11a,12a) is defined in a side surface of the substrate, and the amorphous regions of two sides (11,12) adjacent to each other have different depths from a top surface of the substrate.
