Abstract:
1. A light emitting diode, comprising: a substrate; a plurality of metal patterns arranged on the substrate and spaced apart from one another, each of the metal patterns consisting of metal layers; a plurality of light emitting cells arranged directly on the metal patterns, respectively, the light emitting cells consisting of III-V based semiconductor layers and being spaced apart from one another, each of the light emitting cells comprising a first conductive-type lower semiconductor layer, an AlInGaP active layer, and a second conductive-type upper semiconductor layer; a semi-insulating or insulating layer disposed between the substrate and the metal patterns; and wires to connect the plurality of light emitting cells in series, wherein each of the plurality of metal patterns comprises an adhesive metal layer and a reflective metal layer, and the reflective metal layer is interposed between the light emitting cell and the adhesive metal layer, and the reflective metal layer and the adhesive metal layer comprise different materials from each other, and wherein the plurality of light emitting cells are positioned directly on the reflective metal layer.
