Abstract
The present invention relates to a light-emitting diode (LED), which comprises electrodes having a single metal reflective layer. The single metal reflective layer is thicker than the active layer of the LED. Thereby, at least a portion of light emitted from the active layer is reflected by the single metal reflective layer, and thus enhancing the light-emitting efficiency of the LED.
