Abstract

A laminated Organic Light Emitting Diode (OLED) display panel and a manufacturing method thereof and a display device are provided. The laminated OLED display panel includes: a pixel partition layer, which defines a plurality of openings; a first charge generate layer, which has a first doping type, being positioned on the pixel partition layer; and a second charge generate layer, which has a second doping type, being positioned on the first charge generate layer. The laminated OLED display panel further includes: a barrier layer, which is positioned between the first charge generation layer and the second charge generation layer and at least corresponds to a position of the pixel partition layer.
