Claim:
1. A light emitting diode (LED) having distributed Bragg reflector, comprising: an epitaxial layer having a first semiconductor layer, a light emitting layer and a second semiconductor layer, wherein the light emitting layer is interposed between the first semiconductor layer and the second semiconductor layer; a transparent conductive layer disposed on the second semiconductor layer; a Bragg reflective layer disposed on the transparent conductive layer and having a plurality of first through holes penetrating through the Bragg reflective layer; a first electrode electrically connected to the first semiconductor layer; a second electrode electrically connected to the transparent conductive layer; and a plurality of intervals in adjoining through holes of the plurality of first through holes and a plurality of distances between the plurality of first through holes and the second electrode, wherein the plurality of intervals gradually decrease as the plurality of distances gradually increase.
