Abstract
A light emitting diode comprises a substrate, a buffer layer, a semiconductor layer and a semiconductor light emitting layer. The buffer layer is disposed on the substrate. The semiconductor layer is disposed on the buffer layer. The semiconductor light emitting layer is disposed on the semiconductor layer. A plurality of voids is defined within the semiconductor layer. Each void encloses air therein. A method for manufacturing the light emitting diode is also provided. Light generated by the semiconductor light emitting layer toward the substrate is reflected by the voids to emit out of the light emitting diode.
