Title:
LIGHT EMITTING DIODE HAVING DISTRIBUTED BRAGG REFLECTOR
Document Type and Number:
WIPO Patent Application WO/2012/015153
Kind Code:
A2
Abstract:
A light-emitting diode having a distributed Bragg reflector is disclosed. The light-emitting diode includes a light-emitting structure arranged on a first surface of a substrate, the light-emitting structure including a first semiconductor layer, a second semiconductor layer, and an active layer interposed between the first layer and the second layer. A first distributed Bragg reflector (DBR) is arranged on a second surface of the substrate opposite to the first surface, the first DBR to reflect light emitted from the light-emitting structure. The first DBR has a reflectivity of at least 90% with respect to light of a first wavelength in a blue range, light of a second wavelength in a green range, and light of a third wavelength in a red range. The first DBR has a laminate structure having an alternately stacked SiO2 layer and Nb2O5 layer.
