Array substrate for liquid crystal display device 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 to connect to a gate pad;
• forming a data line on the substrate to connect to a data pad and to cross the gate line to define a pixel region;
• forming 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;
• forming 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;
• simultaneously forming a black matrix and a first conductive pattern on the passivation layer, wherein the black matrix is formed over the thin film transistor, and the first conductive pattern covers the first contact hole;
• and
• simultaneously forming a pixel electrode, an auxiliary gate pad and an auxiliary data pad on a surface of the passivation layer, wherein the pixel electrode contacts the first conductive pattern at the pixel region, the auxiliary gate pad is connected to the gate pad through the second contact hole, and the auxiliary data pad is connected to the data pad through the third contact hole.
