Abstract: A light emitting diode includes a substrate, a first semiconductor layer, an active layer, a second semiconductor layer, a first electrode, a transparent conductive layer, a second electrode and a metal grating. 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 transparent conductive layer is located on a surface of the second semiconductor layer away from the substrate. The second electrode is electrically connected to the transparent conductive layer. The metal grating is located on a surface of the transparent conductive layer away from the substrate. The metal grating is a two-dimensional array of a plurality of metal micro-structures.
