This disclosure relates to an array substrate wiring and manufacturing and repairing method thereof. The array substrate wiring comprises a first wiring formed on the substrate for transmitting electric signals; an insulating layer formed on the first wiring; a second wiring formed on the insulating layer, being opposite to the first wiring, the second wiring being in a hanging state and not transmitting electric signals. By means of such a double layer wiring structure, the holes produced in the insulating layer are blocked using the second wiring in the upper layer, such that the outside moisture cannot reach the first wiring via the holes in the insulating layer, thereby protecting the first wiring for transmitting electric signals from corrosion and scratch.
