Array substrate for in-plane switching mode liquid crystal display device and manufacturing method thereof

A method of forming an array substrate for an in-plane switchng liquid crystal display device, comprising:

• forming a gate line and a gate electrode on a substrate;
• forming a gate insulation layer on the substrate to cover the gate line and the gate electrode;
• forming a semiconductor layer on the gate insulation layer;
• forming a source electrode and a drain electrode on the semiconductor layer and simultaneously forming a data line, a pixel connecting line and a plurality of light-shielding patterns on the gate insulation layer, thereby defining an intermediate structure;
• forming a passivation layer over the substrate to cover the intermediate structure, the passivation layer having a plurality of contact holes;
• and
• forming a common electrode and a plurality of common and pixel electrodes on the passivation layer, the plurality of common and pixel electrodes having a substantially zigzag shape.

A method of forming an array substrate for an in-plane switchng liquid crystal display device, comprising:

• forming a gate line arranged in a first direction on a substrate;
• forming a data line arranged in a second direction perpendicular to the gate line, the data line define a pixel region with the gate line;
• forming a plurality of common electrodes located in the pixel region and arranged in the second direction;
• forming a common line arranged in the first direction and connected to the pluarity of common electrodes;
• forming a plurality of pixel electrodes located in the pixel region and arranged in the second direction, the plurality of pixel and common electrodes having at least one bent portion;
• and
• forming a plurality of light-shielding patterns between one end of the pixel electrode and the intersection of the common line and at least one common electrode.
