Abstract
A light emitting device may include a substrate, an n-type clad layer, an active layer, and a p-type clad layer. A concave-convex pattern having a plurality of grooves and a mesa between each of the plurality of grooves may be formed on the substrate, and a reflective layer may be formed on the surfaces of the plurality of grooves or the mesa between each of the plurality of grooves. Therefore, light generated in the active layer may be reflected by the reflective layer, and extracted to an external location.
