Abstract: A light-emitting device includes a semiconductor stack, a first electrode, a first electrode pad, and second electrode pads. The semiconductor stack includes a first semiconductor layer, a first mesa formed on the first semiconductor layer, and second mesas spaced apart from each other and formed on the first semiconductor layer and separated from the first mesa. The first mesa and the second mesas respectively include a second semiconductor layer on having a second conductivity type different from a first conductivity type of the semiconductor stack. The first electrode covers and contacts the first mesa and is electrically connected to the first semiconductor layer. The first electrode pad is formed on the first mesa and is connected to the first electrode layer. The second electrode pads are formed on the second mesas, and are electrically connected to the second semiconductor layer of each of the second mesas.
