Abstract
A pixel area of an in-plane switching mode LCD (IPS-LCD) device has at least two common electrodes extending along Y-axis direction and at least a pixel electrode extending along Y-axis direction, in which the pixel electrode is disposed between the two adjacent common electrodes in parallel. The common electrode and the pixel electrode have the same profile that is connected by a first strip-shaped segment, a second strip-shaped segment, a third strip-shaped segment and a fourth strip-shaped segment in sequence. The first segment is not parallel to the second segment, the first segment is not parallel to the third segment, the second segment is not parallel to the fourth segment, and the third segment is not parallel to the fourth segment.
