Abstract
An organic electrogenerated light-emitting diode device, manufacturing method, and display device thereof are provided. The method comprises: a first organic common layer and a first light-emitting layer are formed in a pixel region of the array substrate. A opening area of different organic light-emitting material layers are set by adjusting a distance between the fine metal mask and the array substrate, the opening area is proportional to the distance between the fine metal mask and the array substrate. At least a second light-emitting layer is formed on the first light-emitting layer.
