Abstract: A display panel, a method for manufacturing the display panel and a display device are provided. The display panel includes a flexible substrate, a surface of which is provided with a plurality of protrusions; a plurality of organic light-emitting elements disposed on the flexible substrate, at least a portion of the plurality of organic light-emitting elements being located within regions where the protrusions are located. Therefore, parts with the organic light-emitting elements can be stepped by utilizing the protrusions of the flexible substrate, so a thickness of the flexible substrate except the protrusions can be effectively reduced, and the display panel can be in contact with other structures by utilizing the protrusions, so that the portion of the flexible substrate except the protrusions has a deformation space of higher freedom, and a tensile strength of the display panel can be improved.
