1. An array substrate including a display region that displays an image and a frame region that surrounds said display region, said array substrate comprising:

  • a plurality of scanning lines that are formed in parallel in said display region and are extended to said frame region;

    a plurality of signal lines that are formed to intersect said plurality of scanning lines, are formed to be in parallel in said display region, and are extended to said frame region;

    a thin film transistor disposed at an intersection of each of said plurality of scanning lines and each of said plurality of signal lines;

    a first driving IC chip in said frame region and connected to the plurality of scanning lines;

    a second driving IC chip in said frame region and connected to the plurality of signal lines;

    a plurality of in-frame wires formed in said frame region;

    an insulating layer that vertically separates said scanning lines and said signal lines from said in-frame wires in said frame region; and

    a plurality of connection converters that electrically connect said scanning lines or said signal lines to said in-frame wires and are provided in said frame region, whereina single contact hole that penetrates said insulating layer is formed in each of said connection converters, and each of said scanning lines or each of said signal lines is electrically connected with each of said in-frame wires through a conductive film in said single contact hole,said single contact hole has dimensions such that a terminal of an inspection device inspecting lines for breaks is allowed to be inserted in said single contact hole and said terminal is allowed to be in contact with said conductive film in said single contact hole,said connection converters do not overlap with said first and second driving IC chips in a plan view, andeach of said scanning lines or each of said signal lines extends towards one of said connection converters in a same direction as said electrically connected in-frame wire extends away from said one connection converter.
