The invention discloses a display panel, a restoration method thereof and a display device. By arranging a first mending wire to a peripheral zone, the first mending wire is not intersected with any data line such that width of the first mending wire can be adjusted and electrical resistance of the first mending wire is reduced. Therefore, voltage attenuation during the process of uploading and transmitting the first mending wire is reduced. Meanwhile, a third winding wire comprising a third line segment, or a fourth line segment and a fifth line segment is arranged such that a data signal used for restoration is transmitted to the other end of a data line with interrupted signals through the third line segment, or the fifth line segment and the fourth line segment. Intersection between any mending wire and any data line is avoided. Therefore, delay of mending wires for data signals is reduced in order to ensure that data signals can be charged to corresponding pixels within short time.
