Claim:
1. A light emitting diode comprising; a substrate; stacked layers including an n layer, a p layer, and an active layer formed on the substrate; and side walls of the stacked layers; wherein an upper plane or a lower plane of the substrate or a plane where the substrate is placed forms a reference plane; slanted active layer curves are formed on the active layer which deviate from and are slanted to the reference plane; and slanted curves are formed on the side walls and are slanted to the reference plane; one or more layers with respective refractive indices which cover the curves and maintain the shape of the curves along the shape of the curved plane of the side walls, are included; an area of a cross section of the active layer which is exposed by the side walls expands upwardly and downwardly; direct light emitting is increased with extraction from the side walls of the active layer not passing through the n layer and the p layer; and slope is partially different along the direction of the height of the side walls.
