Abstract: The application provides a wiring structure, a display substrate, and a display device, which pertain to the field of display technologies. The wiring structure includes a plurality of hollow units connected in series, and each of the hollow units includes a hollow area and a non-hollow area. The non-hollow areas of any two adjacent hollow units at least partially overlap, and the hollow areas thereof do not overlap. Compared with a conventional linear-type wiring structure, the wiring structure can release stress through the hollow area of the hollow unit in the process of bending, stretching, and twisting, so as to avoid breaking of the wiring structure which may result in failure of the device on the substrate that employs the wiring structure.
