摘要: A light emitting diode is provided, wherein a first semiconductor layer is disposed on a substrate, and a second semiconductor layer is disposed on the first semiconductor layer. The first and the second semiconductor layers are doped with different type dopants. In addition, a second electrode is disposed on the second semiconductor layer, and a first electrode is disposed on the first semiconductor layer to surround the second electrode. A dielectric layer is disposed on the substrate to isolates the first electrode from the second electrode. A redistributing circuit is disposed on the dielectric layer. The redistributing circuit is electrically connected to the first electrode and the second electrode to provide a first extending electrode and a second extending electrode. The light emitting diode can prevent the crowding effect and provide better reliability and light emitting efficiency.
