Abstract:
1. A light emitting diode, comprising: a substrate; a plurality of light emitting cells separated from each other on the substrate, and each light emitting cell comprising a lower semiconductor layer, an active layer disposed on at least a portion of the lower semiconductor layer, an upper semiconductor layer, and a transparent electrode layer; a wire layer to electrically connect a lower semiconductor layer of a first light emitting cell to an upper semiconductor layer of a second light emitting cell adjacent to the first light emitting cell; an insulation layer disposed between the wire layer and the plurality of light emitting cells to prevent short circuit in the plurality of light emitting cells due to the wire layer; and micro-lenses formed on outside surfaces of the plurality of light emitting cells an on an upper surface of the substrate between the first light emitting cell and the second light emitting cell, the micro-lenses each comprising a horizontal diameter less than a diameter of each light emitting cell, wherein: at least two of the micro-lenses are disposed above each light emitting cell in a vertical direction, and the micro-lenses are formed along the outside surfaces of the plurality of light emitting cells.
