A manufacturing method for a flexible panel (10), the flexible panel (10), and a display device. The manufacturing method for the flexible panel (10) comprises: providing a rigid substrate (20), the rigid substrate (20) including a first face (22) and a second face (24) opposite to the first face (22), and forming a flexible underlay (12) on the first face (22); forming a device layer (14) on the flexible underlay (12), forming a protective film (16) on the device layer (14), the protective film (16) being attached to the rigid substrate (20), and forming the flexible panel (10) by the flexible underlay (12), the device layer (14) and the protective film (16); performing a laser lift-off processing from one side of the second face (24) to separate the flexible underlay (12) from the first face (22); cooling the protective film (16) to separate the protective film (16) from the first face (22); and separating the flexible panel (10) from the rigid substrate (20).
