Abstract
An organic light-emitting diode (OLED) display panel, a manufacturing method thereof and a display device are provided. In the manufacturing method, pixel electrodes, required to be deposited with a material, on a base substrate are charged, and electrodes at an evaporation source are charged to form an electric field; evaporation material corresponding to the material required to be deposited are placed into the evaporation source and ionized, and the ionized evaporation material are deposited on the base substrate under the action of the electric field; deposited material in other pixel units are etched off and removed, so that the evaporation material only on the previously charged pixel electrodes on the base substrate are retained; and patterns of the required material are formed by the processes of deposition and etching in turn. The manufacturing method improves the resolution of finished products and can help to improve the resolution of the OLED.
