STACKED ORGANIC LIGHT-EMITTING DIODE AND PREPARATION METHOD THEREFOR, AND DISPLAY DEVICE

摘要

A stacked organic light-emitting diode (100), a display device and a manufacturing method of a stacked organic light-emitting diode (100) are disclosed. A stacked organic light-emitting diode (100) includes at least two light-emitting units (103) in a stacked arrangement and a charge generation layer (107) disposed between the adjacent light-emitting units (103), wherein the charge generation layer (107) includes a first material layer (1071), an electron injection layer (1072) disposed on the first material layer (1071) and a second material layer (1073) disposed on the electron injection layer (1072). By means of said stacked organic light-emitting diode (100) 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).
