Patent ID: 7688413

Claim:
An in-plane switching mode liquid crystal display device, comprising: a pair of substrates facing each other; and a liquid crystal layer interposed between the pair of substrates, wherein one of the pair of substrates includes a plurality of gate wirings and a plurality of data wirings crossing each other, common electrode wirings disposed approximately parallel to the respective gate wirings, switching elements disposed in respective pixel regions surrounded by the gate wirings and the data wirings, and pixel electrodes connected to the switching elements, liquid crystal molecules of the liquid crystal layer within the pixel region are rotated in a plane approximately parallel to the substrate by a voltage applied between a common electrode connected to one of the common electrode wirings and the pixel electrode, stripe-shaped convex parts are formed so as to overlap at least with regions where the data wirings are formed, the pixel electrode is only formed in a region including at least a part of one side wall of the convex part, and does not cross over an aperture of the pixel region, and the common electrode is only formed in a region including at least a part of another side wall of the convex part, and does not cross over the aperture of the pixel region.
