Patent ID: 8735867

Claim:
A group III nitride nanorod light emitting device, comprising: a substrate; an insulating film disposed on the substrate, and including a plurality of openings exposing parts of the substrate and having different diameters; and a plurality of first conductive group III nitride nanorods having different diameters, respectively disposed in the plurality of openings, respective diameters of the plurality of first conductive group III nitride nanorods being greater than or equal to 120 nm but less than 1 μm, wherein: each first conductive group III nitride nanorod of the plurality of first conductive group III nitride nanorods has an active layer and a second conductive semiconductor layer sequentially disposed on a surface of the active layer, the plurality of first conductive group III nitride nanorods include a first group on a first area of the substrate and a second group on a second area of the substrate different from the first area, each group including two or more first conductive group III nitride nanorods that have an identical diameter and an identical height, and the diameter of the nanorods of the first group is smaller than the diameter of the nanorods of the second group.
