The invention discloses a wiring structure of a display substrate. The display substrate comprises at least two display panels on which wiring structures are arranged. Each wiring structure comprisesa first curing pad group which is arranged on the array substrates of the display panels, comprises a first curing pad and a second curing pad, and is used for receiving a common voltage, a first curing line which is connected with the first curing pad and used for transmitting a common voltage to the display panels, and a second curing line of which one end is connected with the second curing padwhile the other end is connected with the first curing line of the first adjacent display panel, wherein when the common voltage is received, the first curing pad transmits the common voltage to thedisplay panels through the first curing line for curing and alignment of the display panels, and the second curing pad transmits the common voltage through the second curing line to the first adjacentdisplay panel for curing and alignment of the first adjacent display panel. Due to the design of the wiring structures, the design freedom of the display substrate is increased.
