Abstract:
1. A high light-extraction efficiency light-emitting diode structure, comprising: a substrate; a light-emitting diode epitaxial layer, including an electron supply layer formed on the substrate, an active layer formed on the electron supply layer, and a hole supply layer formed on the active layer, the electron supply layer having an area larger than the active layer and the hole supply layer; a plurality of electric-conduction layers made of an aluminum-silver alloy, including metallic pads formed on the electron supply layer and the hole supply layer respectively, and mesh wires formed on the electron supply layer and the hole supply layer respectively; and a reflective metal layer formed on one side of the substrate opposite to the light-emitting diode epitaxial layer, wherein the metallic pads, the metallic mesh wires and the reflective metal layer reflect light generated by the active layer.
