Abstract
A light emitting diode is disclosed, wherein the light emitting diode comprises a metal reflective layer for enhancing the light reflection efficiency inside the light emitting diode and reducing the resistance to avoid the power loss. In addition, the light emitting diode further comprises a buffer layer sandwiched between the metal reflective layer and a semiconductor layer, wherein the buffer layer is mixed with metal and non-metallic transparent material for reducing the stress between the semiconductor and the metal to decrease the possibility of the die cracking.
