In-plane switching mode liquid crystal display device

An in-plane switching mode LCD device comprising:

• first and second substrates;
• a gate line and a data line arranged horizontally and vertically on the first substrate and defining a pixel;
• a first common electrode disposed in the pixel, the first common electrode including a plurality of first electrodes along the gate and data lines;
• a first pixel electrode disposed in the pixel, the first pixel electrode including a plurality of second electrodes along the gate and data lines;
• a first region in the pixel region defined by two sides of the first electrode and two sides of the second electrode;
• an arc-shaped second common electrode connecting the first sides and an arc-shaped second pixel electrode connecting the second sides, the arc-shaped second common electrode and arc-shaped second pixel electrode being disposed in the first region defined by first and second electrodes to define a second region;
• a first alignment film and a second alignment film at facing surfaces of the first and second substrate;
• and
• a liquid crystal layer between the first and the second substrates.
