Abstract:
1. A liquid crystal display device of an in-plane switching mode comprising: gate lines and data lines configured to cross each other and to define first and second pixel regions arranged to alternate with each other; a thin film transistor formed at each intersection of the gate and data lines and configured to include a source electrode extended from the data line, a drain electrode separated from the source electrode, and a gate electrode extended from the gate line; a pixel electrode configured to include a pixel electrode lead portion connected to the drain electrode, a pixel electrode connection bar extended from the pixel electrode lead portion, and a plurality of pixel electrode protrusions extended from the pixel electrode connection bar; common lines arranged to be separated parallel to the gate lines; and a common electrode configured to include a common electrode connection bar connected to the common line, and a plurality of common electrode protrusions extended from the common electrode connection bar and arranged to alternate with the pixel electrode protrusions, wherein at least one of the first and second pixel regions is configured to include upper and lower portions, wherein the total number of the pixel electrode protrusions and the common electrode protrusions on the upper portion is different from that on the lower portion.
