1. An array substrate, comprising a substrate, and gate lines and data lines arranged to intersect one another on the substrate, wherein the array substrate further comprises:

  • a gate line connection conducting wire layer provided between the gate lines and the substrate and below the gate lines, configured such that when any of the gate lines is broken, the broken gate lines can be conducted through the gate line connection conducing wire layer therebelow, thereby achieving reconnection of the gate lines;

    a data line connection conducting wire layer provided in regions of the array substrate corresponding to the data lines; and

    a gate insulation layer located between the data lines and the data line connection conducting wire layer, to completely electrically insulate the data lines from the data line connection conducting wire layer, such that only the gate insulation layer is directly between the data lines and the data line connection conducting wire layer;

    wherein pixel electrode regions are delimited between the gate lines and the data lines,wherein the gate line connection conducting wire layer is electrically isolated from the data line connection conducting wire layer; and

    wherein when any of the data lines is broken, two disconnected ends of the broken data line and the data line connection conducting wire layer are bridgeable by a bonding wire, so that the broken data line is reconnected.
