1. An organic light-emitting diode (OLED) display panel, comprising:
a drive backplane; and
an OLED device, an encapsulation structure and a color resistor structure which are arranged on the drive backplane; wherein
the OLED device comprises a first electrode layer electrically connected with the drive backplane, a light-emitting structure layer and a cathode, and a surface of a side, facing away from the drive backplane, of the first electrode layer is a rough surface;
the encapsulation structure and the color resistor structure are arranged on a side, facing away from the drive backplane, of the OLED device;
the color resistor structure comprises a chromatic color resistor layer, a first black matrix BM) and a second BM; and
the first BM is arranged on a side, facing away from the drive backplane, of the chromatic color resistor layer, and the second BM is arranged on a side, facing the drive backplane, of the chromatic color resistor layer.
