Abstract
A light emitting diode includes a substrate, a first semiconductor layer, an active layer, a second semiconductor layer, a first electrode, and a second electrode. The first semiconductor layer, the active layer, and the second semiconductor layer are orderly stacked on the substrate. The first electrode is electrically connected to the first semiconductor layer. The second electrode electrically is connected to the second semiconductor layer. The substrate has a number of three-dimensional nano-structures, and each of the number of three-dimensional nano-structures has a stepped structure.
