Abstract:
A light emitting diode structure includes a first type semiconductor layer, a second type semiconductor layer, an active layer disposed therebetween, and a reflective stacked layer. The reflective stacked layer includes a first reflective layer and a second reflective layer. The first reflective layer is disposed at a side of the second type semiconductor layer opposing the active layer. The second reflective layer is disposed at a side of the first reflective layer opposing the second type semiconductor layer, and extends along a side surface of the first reflective layer to a surface of the second type semiconductor layer. A vertical projection area of the second reflective layer on the second-type semiconductor layer is greater than that of the first reflective layer thereon. The second reflective layer has a better resistance to migration than the first reflective layer.
