Flexible display panel and display device

The invention provides a flexible display panel and a display device, the flexible display panel comprises a bending area and a non-bending area, in the bending area, the flexible display panel comprises a substrate, a circuit layer and at least two stress release layers, the circuit layer is formed on one side of the substrate, a plurality of signal lines are formed through patterning, and the stress release layers are formed on the other side of the substrate. The at least two stress release layers are arranged on the side, away from the substrate, of the circuit layer, and the elasticity moduli of any two adjacent stress release layers in the at least two stress release layers are different. According to the application, the at least two stress release layers with different elastic moduli are arranged on the circuit layer of the bending area, and the stress caused by an external experiment is dispersed in the stress release layer with the relatively large elastic modulus and is absorbed in the stress relea
