PURPOSE: A light emitting device is provided to increase current spread by connecting a first electrode to four light emitting regions at the same time. CONSTITUTION: A light emitting structure(120) includes a first conductive semiconductor layer, an active layer, and a second conductive semiconductor layer. A first electrode(160) is formed in a part of the first conductive semiconductor layer. A second electrode(170) is arranged in the upper part of the second conductive semiconductor layer. A trench region exposes a part of the first conductive semiconductor layer to a first and a second direction. The first electrode is arranged on the first conductive semiconductor layer.
