Abstract:
1. An array substrate for a liquid crystal display (LCD) device, comprising: first and second gate lines crossing a data line on a substrate to define first and second pixel regions; a thin film transistor (TFT) including a source electrode that extends from the data line, a drain electrode spaced apart from the source electrode, a semiconductor layer on an insulating layer positioned between the gate electrode and the source and drain electrodes; a metal pattern on the semiconductor layer that overlaps a common line and makes up a portion of the drain electrode; a passivation layer disposed on the source and drain electrodes and on the metal pattern; a first pixel electrode on the passivation layer and connected to the metal pattern; a common electrode on the passivation layer and connected to the common line; and a repair pattern on the semiconductor layer connected to the drain electrode at one end thereof and overlapping under a second pixel electrode of the second pixel region at another end thereof to define a repairing portion, wherein the repair pattern is formed of the same layer and the same material as the drain electrode.
