Abstract:
1. An array substrate for a liquid crystal display device, comprising: a substrate; a gate line on the substrate, the gate line connected to a gate pad; a data line on the substrate, the data line connected to a data pad and crossing the gate line for defining a pixel region; a thin film transistor connected to the gate line and the data line, the thin film transistor having a gate electrode and source and drain electrodes; a passivation layer over the gate line, the data line, and the thin film transistor, the passivation layer having a first contact hole exposing the drain electrode, a second contact hole exposing the gate pad, and a third contact hole exposing the data pad; a black matrix on the passivation layer over the thin film transistor; a first conductive pattern covering the first contact hole, wherein the first conductive pattern is formed of the same material as the black matrix, and wherein the first conductive pattern is formed in the same layer as the black matrix; a pixel electrode on a surface of the passivation layer at the pixel region, the pixel electrode contacting the first conductive pattern; an auxiliary gate pad connected to the gate pad through the second contact hole; and an auxiliary data pad connected to the data pad through the third contact hole.
