PURPOSE: A light emitting diode is provided to increase light efficiency and light uniformity by dividing the light emitting diode into loop areas. CONSTITUTION: A first electrode and a second electrode(402) are arranged between a first doped layer and a substrate(32). The first electrode and the second electrode are electrically connected to the first doped layer. An active layer is arranged on the first doped layer. A second doped layer is arranged on the active layer. A third electrode and a fourth electrode(422) are arranged on the second doped layer. The third electrode and the fourth electrode are electrically connected to the second doped layer. A pattern of the third electrode is separated from a pattern of the fourth electrode.
