Patent ID: 6958743

Claim:
An array substrate for a liquid crystal display device, comprising: a substrate; a gate line on the substrate; a gate insulating layer on the gate line; a data line on the gate insulating layer, the data line crossing the gate line; a data link line extending from the data line; a data pad connected to the data link line; a redundancy line adjacent to the data link line; 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; 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; 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 a pixel electrode on the passivation layer.
