PURPOSE: A light emitting device is provided to improve a current spreading phenomenon by including a low carrier concentration layer on a first semiconductor layer. CONSTITUTION: A second conductive layer(230) is arranged on a first conductive layer(220). A second semiconductor layer(250) is arranged on the second conductive layer. An active layer(260) is arranged on the second semiconductor layer. A first semiconductor layer(240) is arranged on the active layer. The first semiconductor layer includes a low carrier concentration layer(280). |
