    Abstract: An LED includes a gallium nitride substrate, a first semiconductor layer disposed thereon, and a mesa including a second semiconductor layer disposed on the first semiconductor layer and an intervening active layer. A first contact layer includes an outer contact part in contact with the first semiconductor layer near an edge of the substrate and an inner contact part in contact with the first semiconductor layer within a region encompassed by the outer contact part. A second contact layer is disposed on the mesa in contact with the second semiconductor layer. An upper insulation layer has first and second opening parts overlapping the first and second contact layers. First and second electrode pads are electrically connected to the first and second contact layers through the first and second opening parts. The LED can be driven at 150-315 A/cm2 and has a maximum junction temperature of 150-190° C.
