Abstract
A top-emitting light-emitting diode includes a glass substrate, a polysilicon layer, a white light emitting layer and a transparent conductive layer. The polysilicon layer is formed on a first surface of the glass substrate. Moreover, plural sub-wavelength structures are discretely arranged on a surface of the polysilicon layer at regular intervals. The white light emitting layer is formed over the polysilicon layer and the plural sub-wavelength structures. The transparent conductive layer is formed over the white light emitting layer.
