An organic lighting-emitting diode (OLED) display panel, a backplane attaching method and a backplane attaching device are provided. The OLED display panel includes: a flexible substrate, and a thin film transistor layer and a light-emitting layer prepared on the flexible substrate. The flexible substrate includes a first flexible substrate layer, a fixing layer and a second flexible substrate layer sequentially stacked one another. The fixing layer includes an organic film layer and magnetic particles embedded in the organic film layer. The magnetic particles are located in an internal of the flexible substrate.
