Abstract: A light-emitting diode includes a first semiconductor layer, a light-emitting layer and a second semiconductor layer, having an upper surface providing a first electrode area containing a pad area and an extended area; a transparent conductive layer over the first semiconductor layer having a first opening to expose a portion of a surface of the first semiconductor layer corresponding to the pad area; a protective layer over the transparent conductive layer having a second opening and a third opening respectively at positions corresponding to the pad area and the extended area, while exposing a portion of the surface of the first semiconductor layer corresponding to the pad area and a portion of a surface of the transparent conductive layer corresponding to the extended area; and a first electrode over the protective layer directly contacting the first semiconductor layer corresponding to the pad area via the first and second openings.
