A light emitting diode with strained layer superlatices (SLS) crystal structure is formed on a substrate. A nucleation layer and a buffer layer are sequentially formed on the substrate, so as to ease the crystal growth for the subsequent crystal growing process. An active layer is covered between an upper and a lower cladding layers. The active later include III-N group compound semiconductive material. A SLS contact layer is located on the upper cladding layer. A transparent electrode is located on the contact later to serve as an anode. Another electrode layer has contact with the buffer layer, and is separated from the lower and upper cladding layers.
