Array substrate for liquid crystal display device having redundancy line and fabricating method thereof

A fabricating method of an array substrate for a liquid crystal display device, comprising:

• forming a gate line on a substrate;
• forming a gate insulating layer on the gate line;
• forming a data line on the gate insulating layer, the data line crossing the gate line;
• forming a data link line extending from the data line;
• forming a data pad connected to the data link line;
• forming a redundancy line adjacent to the data link line;
• forming a passivation layer covering the data link line, the data pad and the redundancy line, the passivation layer having a data link line contact hole exposing the data link line, first and second redundancy line contact holes exposing the redundancy line and a data pad contact hole exposing the data pad;
• forming a data pad terminal connected to the data pad through the data pad contact hole and to the redundancy line through the first redundancy line contact hole;
• forming a redundancy electrode connected to the redundancy line through the second redundancy line contact hole and to the data link line through the data link line contact hole;
• and
• forming a pixel electrode on the passivation layer.
