Patent ID: 8183576

Claim:
A light-emitting diode, comprising: a reflection electrode on a supporting substrate, wherein the supporting substrate has electrical conductivity; a plurality of nano-rods on the reflection electrode, the reflection electrode being interposed between the supporting substrate and the plurality of nano-rods, wherein the plurality of nano-rods extend perpendicularly from an upper surface of the reflection electrode, and each of the nano-rods includes a first region doped with a first type dopant, a second region doped with a second type dopant that is an opposite type to the first type dopant, and an active region between the first region and the second region; a transparent insulating layer between the plurality of nano-rods; a transparent electrode on the plurality of nano-rods and the transparent insulating layer; and an epitaxy layer between the transparent electrode and the plurality of nano-rods, wherein the epitaxy layer and the plurality of nano-rods are formed of the same material.
