Abstract: The present disclosure provides 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 is formed over a base substrate. A graphene oxide layer is formed over the pattern of the anode layer by an electroplating process. The graphene oxide layer 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 barrier may be reduced and to 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.
