Description

technical field [0001] The present invention relates to the field of display devices, and in particular, relates to an organic light emitting diode, a method for manufacturing the organic light emitting diode, and a display device including the organic light emitting diode. Background technique [0002] An organic light emitting diode includes an anode layer, a hole injection layer, a hole transport layer, a light emitting layer, an electron transport layer, an electron injection layer and a cathode which are stacked in sequence. At present, the above-mentioned different layers are usually formed by vacuum evaporation. [0003] Organic light-emitting diodes comprising multiple layers are generally produced using different processes. For example, a cathode layer, an electron injection layer, an electron transport layer, and a light emitting layer can be formed by vacuum evaporation, and a hole transport layer and a hole injection layer can be formed by a solution method.
