    摘要： Exemplary embodiments of the present invention relate to light emitting diodes. A light emitting diode according to an exemplary embodiment of the present invention includes a substrate having a first side edge and a second side edge, and a light emitting structure arranged on the substrate. The light emitting structure includes a first conductivity-type semiconductor layer, an active layer, and a second conductivity-type semiconductor layer. A transparent electrode layer including a concave portion and a convex portion is arranged on the second conductivity-type semiconductor layer. A first electrode pad contacts an upper surface of the first conductivity-type semiconductor layer and is located near a center of the first side edge. Two second electrode pads are located near opposite distal ends of the second side edge to supply electric current to the second conductivity-type semiconductor layer. A first pad extension extends from the first electrode pad and a second pad extension extends from each of the two second electrode pads.
