Patent ID: 8648329

Claim:
A light-emitting device comprising: a first layer having a first surface; a second layer having a second surface that faces the first surface; and a semiconductor body interposed between the first and second surfaces, wherein the semiconductor body has a first fine-wall-shape member, a second fine-wall-shape member, and a semiconductor member, the first and second fine-wall-shape members having a third layer adjacent to the first surface; a fourth layer adjacent to the second surface; and a fifth layer interposed between the third and fourth layers, the semiconductor member is interposed between the first and second fine-wall-shape members, the first and second layers are made of GaN, the third, fourth, and fifth layers and the semiconductor member are made of In x Ga 1-x N (0<x<1), a value x of the fifth layer is larger than values x of the third and fourth layers and the semiconductor member, the fifth layer is a layer that generates light and guides the light, the third and fourth layers are layers that guide the light generated in the fifth layer, and the first and second layers are layers that suppress leakage of the light generated in the fifth layer.
