LIGHT EMITTING DIODE

The present invention provides a light emitting diode configured to prevent a reduction in light emitting area resulting from formation of an electrode or electrode pad. The light emitting diode includes a lower semiconductor layer formed on a substrate; an upper semiconductor layer disposed above the lower semiconductor layer to expose at least a portion of edge regions of the lower semiconductor layer; a first electrode formed on a region of the upper semiconductor layer, with an insulation layer interposed between the first electrode and the region of the upper semiconductor layer, to supply electric current to the lower semiconductor layer; a second electrode formed on another region of the upper semiconductor layer to supply electric current to the upper semiconductor layer; and an extension part of the first electrode extending from the first electrode to at least a portion of the exposed lower semiconductor layer.
