摘要： An organic light-emitting diode (OLED) display device, a manufacturing method thereof, and a display apparatus containing the OLED display device. A pattern of an anode layer(001,200) is formed over a base substrate(002,100). A graphene oxide layer(300) is formed over the pattern of the anode layer(001,200) by an electroplating process. The graphene oxide layer(300) is used as an auxiliary layer or is used as at least one of a hole injection layer and a hole transport layer in the OLED display device. Since the graphene oxide material has high work function, the hole injection voltage barrier may be reduced and the hole injection and hole transport capability of the OLED display device may be enhanced to improve light emitting performance of the OLED display device.
