The embodiment of the invention discloses a display panel, a display device and a manufacturing method thereof. The display panel comprises a substrate, a pixel driving circuit array and an organic light-emitting unit array, wherein the substrate comprises a first hardened layer and an elastic stretching layer; the face, away from the elastic stretching layer, of the first hardened layer is a first face, and the face, away from the first hardened layer, of the elastic stretching layer is a second face. The elastic modulus of the first hardened layer is smaller than that of the elastic stretching layer; when the tension is not applied to the display panel, the first face comprises a plurality of first convex bending parts which extend in the first direction and are arranged in the second direction, the convex directions of the first convex bending parts deviate from the second face, and organic light-emitting units are located in the areas where the first convex bending parts are located; when tension is appli
