The invention discloses a flexible display panel and a flexible display device, and relates to the technical field of display. The flexible display panel comprises a flexible substrate, a flexible display part and an electrostatic shielding layer, wherein the flexible display part is arranged on a first surface of the flexible substrate, the electrostatic shielding layer is arranged on a second surface of the flexible substrate, a part, at least arranged on a bending region of the flexible display panel, of one side, deviating from the flexible substrate, of the electrostatic shielding layer is of a first wrinkled structure, the first wrinkled structure comprises at least one first wrinkled bulge, and a protruding direction of the first wrinkled bulge deviates from the flexible substrate. The part, at least arranged on the bending region of the flexible display panel, of one side, deviating from the flexible substrate, of the electrostatic shielding layer is of the first wrinkled structure, the electrostatic shielding layer is arranged at the wrinkled structure of the bending region and can be used for transferring and releasing an external force when the bending external force with a certain stretching trend or compression trend is applied to the electrostatic shielding layer, and the electrostatic shielding layer is prevented from being broken or a functional film layer of the flexile display device is prevented from being damaged after bending for many times.
