Patent abstract
Provided is a light-emitting device and a method of manufacturing the same. The light-emitting device includes a substrate having at least one protruded portion with a curved surface in which a consistent defect density and uniform stress distribution can be obtained even when the growth of the semiconductor crystal layer and the forming of the light-emitting device are completed. In addition, the light-emitting device has a high the light extraction efficiency for extracting light generated at an electroluminescense layer externally.
