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.

The wiring structure includes a plurality of hollow patterns connected successively. Each of the hollow patterns includes a first conductive part having a first pattern and a second conductive part having a second pattern. The first conductive part and the second conductive part are connected with each other, and the first pattern and the second pattern have different shapes. Because the wiring structure includes a plurality of hollow patterns connected successively, and the first conductive part and the second conductive part in each hollow pattern have different shapes, even if the conductive part of one shape in the wiring structure is broken in the process of bending, stretching and twisting, the conductive part of the other shape can also ensure good conductivity for the wiring structure.
