Claim Text:
1. A light-emitting diode with an improved light extraction efficiency, comprising: a semiconductor laminated structure including an N-layer, a light-emitting layer, and a P-layer which are formed on a substrate; an N-type electrode formed on the N-layer including a pad electrode and a dispersion electrode that are adjacent each other in a horizontal direction; a P-type electrode formed on the P-layer including a pad electrode and a dispersion electrode that are adjacent each other in a horizontal direction; and a reflective electrode layer formed over the N-type electrode and the P-type electrode and configured to reflect light on the dispersion electrode, wherein the light-emitting diode further comprises a reflective layer formed between the pad electrode and at least one of the P and N-layers, and wherein the reflective layer is patterned to form a roughness on a surface thereof, and the pad electrode is held on any one of the P and N-layers.
