In-plane switching mode liquid crystal display device and method for fabricating the same

A fabricating method of an in-plane switching mode liquid crystal display device, the method comprising:

• forming a gate line and a data line on a first substrate, the gate and data lines defining a pixel region;
• forming a switching device intersection portion between the gate and data lines;
• forming a pixel electrode and a common electrode on the first substrate, the pixel electrode having a groove around a portion of a transverse pixel line at a crossing portion between the pixel and common electrodes;
• forming a first orientation film on the first substrate;
• forming a second orientation film on a second substrate;
• and
• forming a liquid crystal layer between the first and second substrates.

An in-plane switching liquid crystal display device, comprising:

• first and second substrates;
• gate lines in a first direction on the first substrate;
• data lines in a second direction on the first substrate;
• whereby the gate and data lines define pixel regions;
• each pixel region including:
• a thin film transistor;
• a common electrode on the first substrate parallel to the gate lines;
• sub-common electrodes connected to the common electrode and perpendicular to the gate lines;
• a transverse common line perpendicular to the sub-common electrodes and intersecting at least one of the sub-common electrodes;
• a pixel electrode on the first substrate parallel to the gate lines;
• sub-pixel electrodes connected to the pixel electrode and perpendicular to the gate lines;
• a transverse pixel line perpendicular to the sub-pixel electrodes and intersecting at least one of the sub-pixel electrodes;
• and
• a projection formed at an intersection of the transverse common line and the at least one sub-common electrode.
