Abstract: In order to increase the transmittance around a pixel and to increase the brightness of the screen in an IPS mode liquid crystal display device, a pixel electrode with a slit is formed on a common electrode through an interlayer insulating film. An opening is formed in the common electrode on the outside of the end portion of the pixel electrode as seen in a plane view. Because of the presence of the opening, the electric field lines from the end portion of the pixel electrode reach the layer above the liquid crystal layer and reach further away from the end portion of the pixel electrode, so that it is possible to increase the control ability to the liquid crystal around the pixel. As a result, the pixel transmittance can be increased as a whole and the brightness of the screen can be increased.

Abstract: An IPS LCD that not only increases the screen luminance but also prevents the occurrence of image blurs by reducing the area of disclination and preventing the liquid crystal molecules from rising in a direction normal to the TFT substrate. A pixel electrode is disposed in the pixel surrounded by two gate lines and two data lines. A planar common electrode is located below the pixel electrode with an inter-layer insulating film provided therebetween. The pixel electrode includes slits each being open at the edge on one side and has the shape of a comb. Liquid crystals with negative dielectric anisotropy are used as liquid crystal. The above structure increases the transmissive area of the pixel up to the open edges of the slits and also prevents the liquid crystal molecules from rising in a direction normal to the TFT substrate, thereby preventing the occurrence of blurs.
