Disclosed herein is a light-emitting diode including: a substrate; and at least two light-emitting cell groups positioned on the substrate and having a plurality of light-emitting cells connected to each other in series, in which the at least two light-emitting cell groups each are separately driven, spaced apart from each other at a predetermined interval to be insulated from each other, and have different areas and the light-emitting cell group includes: a plurality of light-emitting cells including first semiconductor layers, active layers, and second semiconductor layers and provided with grooves through which the first semiconductor layers are exposed; a first electrode disposed on the second semiconductor layer; an insulating layer covering the plurality of light-emitting cells to expose portions of the first electrode and the first semiconductor layer; and a connection electrode electrically connected to the exposed portions of the first electrode and first semiconductor layer. |
