Patent ID: 7639336

Claim:
An in-plane switching mode liquid crystal display device, comprising: a substrate; at least two gate lines disposed on the substrate; at least two data lines disposed on the substrate crossing the gate lines to define a pixel region; a driving device disposed in the pixel region; a first line and a second line disposed in the pixel region, the first line being overlapped with the second line to form the storage capacitor; a plurality of first electrodes connected to the first line in the pixel region; and a plurality of second electrodes connected to the second line in the pixel region parallel with the first electrodes and at least one first electrode being partially overlapped with at least one second electrode, each one of the first electrodes and a corresponding one of second electrodes defining an electric field in a direction parallel to a surface of the substrate, the first and second electrodes being alternately disposed, wherein the pixel region is divided into two regions by the first and second lines and the first electrode and the second electrode are respectively overlapped at the upper side of one region and the lower side of other region of the divided two regions, the sum of the overlap region of the first electrode and the second electrode at the divided two regions is constant when the overlap area of the first and second electrodes are varied in the divided two regions by mis-aligning process, the first electrode and the second electrode are insulated each other and the signal to the first electrode is different from that of the second electrode.
