More Information
Summary:A light emitting diode (LED) having distributed Bragg reflector (DBR) and a manufacturing method thereof are provided. The distributed Bragg reflector is used as a reflective element for reflecting the light generated by the light emitting layer to an ideal direction of light output. The distributed Bragg reflector has a plurality of through holes, such that the metal layer and the transparent conductive layer disposed on two sides of the distributed Bragg reflector may contact each other to conduct the current. Due to the distribution properties of the through holes, the current may be more uniformly diffused, and the light may be more uniformly emitted from the light emitting layer.
