A flexible display panel, a flexible display device, and a fabrication method of the flexible display panel are provided. The flexible display panel comprises a stacked structure having a plurality of layers comprising a flexible substrate, a light-emitting device layer, and a polarizing layer stacked in a preset order. The flexible display panel further includes at least one upper-side resistive force-sensitive electrode disposed on a layer above a neutral plane of the stacked structure, and at least one lower-side resistive force-sensitive electrode disposed on a layer below the neutral plane.
