    Abstract: A stacked organic light-emitting diode, a display device and a manufacturing method of a stacked organic light-emitting diode are disclosed. A stacked organic light-emitting diode includes at least two light-emitting units in a stacked arrangement and a charge generation layer disposed between the adjacent light-emitting units, wherein the charge generation layer includes a first material layer, an electron injection layer disposed on the first material layer and a second material layer disposed on the electron injection layer. By means of said stacked organic light-emitting diode and manufacturing method thereof, it can achieve excellent electron injection effect, even in the case of manufacturing an inverted-type stacked organic light-emitting diode (the lower electrode is a cathode).
