Abstract
In a region where data wirings are formed on a TFT substrate, convex parts, each having a trapezoidal cross section or the like, are formed. A pixel electrode is formed on one of side faces of the convex part, and a common electrode is formed on the other side face. Furthermore, the pixel electrodes and the common electrodes are set to face each other between the convex parts adjacent to each other.

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 formed in a region including at least a part of the one side walls of the convex part, and
- the common electrode is formed in a region including at least a part of the other side wall of the convex part.
