Abstract

The present invention discloses a light emitting diode which includes a first ohmic contact layer, a first substrate having a rough surface, a pile of semiconductor layers, a second substrate and a second ohmic contact layer. The rough surface of the first substrate may enhance photon scattering and thus raise the efficiency of the light emitting diode.
