## Abstract

The application discloses a wiring structure, a display substrate and a display device. The wiring structure provided includes a plurality of hollowed pattern strings, each hollowed pattern string including a plurality of hollowed patterns arranged sequentially in a length extension direction of the wiring structure, each hollowed pattern including a hollowed region and a non-hollowed region. The non-hollowed region of any hollowed pattern in a hollowed pattern string at least partially overlaps the non-hollowed region of a hollowed pattern in a further hollowed pattern string adjacent to the hollowed pattern string, and the hollowed regions of the hollowed patterns in the plurality of hollowed pattern strings do not overlap each other. The wiring structure is particularly adapted for flexible display.
