LIGHT EMITTING DEVICE HAVING NANO WIRE AND METHOD OF FABRICATING THE SAME

摘要

A light emitting device and its manufacturing method are provided to improve a light emitting efficiency by increasing a light emissive area using a light emitting structure of a concentric type. A light emitting device includes a substrate, a plurality of nano wires, an active layer and a second semiconductor layer. The plurality of nano wires(110) are spaced apart from each other on the substrate. The nano wire is made of a first semiconductor with a first polarity. The active region(120) is formed along peripheral portions of the substrate and the nano wires. The second semiconductor layer(130) is formed along a peripheral region of the active layer. The second semiconductor layer has a second polarity. An upper surface of the nano wire is sequentially enclosed with the active layer and the second semiconductor layer.
