A flexible display panel, a display device and a forming method are provided. The flexible display panel includes a display area and a non-display area, where the non-display area includes a bending sub-area and a binding sub-area, and the bending sub-area is configured to bend the binding sub-area to a side away from the display area, the bending sub-area includes a first organic layer, a second organic layer and a metal wiring layer between the first organic layer and the second organic layer arranged on the substrate, the touch wiring layer is electrically connected to the metal wiring layer; in response to the bending sub-area being in a bending state, a vertical distance from a bending neutral layer of the bending sub-area to the metal wiring layer is smaller than a preset distance.
