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.
