A light emitting diode includes a substrate tilted toward first and second directions simultaneously, a first cladding layer formed with a semiconductor material of a first conductive type on the substrate, an active layer formed on the first cladding layer, and a second cladding layer formed with a semiconductor material of a second conductive type on the active layer, wherein concavo-convexes are formed on the interfaces of the first cladding layer, the second cladding layer, and the active layer.
