Abstract
The present invention provides a three-dimensional light emitting diode stack and method of manufacturing the same. The three-dimensional light emitting diode stack comprises: a substrate; at least a first light emitting diode stacked on the substrate; and at least a second light emitting diode stacked on the first light emitting diode, wherein energy gap of the first light emitting diode is smaller than that of the second light emitting diode. In the present invention, a material of larger energy gap and shorter wavelength can be penetrated by lights emitted by another material of smaller energy gap and longer wavelength, and lights are mixed together and then emitted, such that the materials are put into a three-dimensional stack arrangement for forming a novel light emitting device of mixed light, so as to emit lights as required.
