Patent ID: 7403252

Claim:
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.
