Patent ID: 8373188

Claim:
A light-emitting diode (LED), comprising: a light-emitting structure arranged on a first surface of a substrate, the light-emitting structure comprising: a first conductivity-type semiconductor layer; a second conductivity-type semiconductor layer; and an active layer interposed between the first conductivity-type semiconductor layer and the second conductivity-type semiconductor layer; and a first distributed Bragg reflector arranged on a second surface of the substrate opposite to the first surface, the first distributed Bragg reflector to reflect light emitted from the light emitting structure, wherein the first distributed Bragg reflector comprises a reflectivity of at least 90% with respect to light of a first wavelength in a blue wavelength range, light of a second wavelength in a green wavelength range, and light of a third wavelength in a red wavelength range, and wherein the first distributed Bragg reflector comprises a laminate structure comprising alternately stacked SiO 2 and Nb 2 O 5 layers.
