Abstract
A light emitting diode includes an active layer, a first type semiconductor layer, a second type semiconductor layer and a pick-up layer. The first type semiconductor layer and the second type semiconductor layer are located on two opposite sides of the active layer respectively. The pick-up layer is located on the second type semiconductor layer, wherein the pick-up layer has a patterned outer surface to serve as a grabbed surface during transferring.
