Abstract:
1. An array substrate for a liquid crystal display, the array substrate comprising: a substrate; a plurality of gate lines and a plurality of thin film transistors each having a gate electrode, a source electrode, a drain electrode and an active layer formed over the substrate; an interlayer insulating layer formed on the thin film transistors; a first gate redundancy line internal to the display formed on the interlayer insulating layer, and connected electrically with just one of the gate electrodes, one of the gate lines, and both gate electrode and gate line through a first gate contact hole and formed of the same material as one of the source and drain electrodes; a passivation layer provided on the first gate redundancy line and the interlayer insulating layer; a pixel electrode electrically connected with the drain electrode through the drain contact hole formed in the passivation; and a second gate redundancy line internal to the display formed on the passivation layer, and connected electrically with the first gate redundancy line through a second gate contact hole.
