摘要： 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.

摘要： A liquid crystal display device prevents an alignment film between an inorganic insulating film and a sealant from peeling off the inorganic insulating film in a seal portion. The device has a TFT substrate and a counter substrate bonded together by the sealant in the seal portion with liquid crystal sandwiched therebetween. The TFT substrate has pixels in a matrix pattern along with the alignment film, and the TFT substrate and the counter substrate are rectangular in external shape. The TFT substrate has a display area and a terminal area. The display area is formed surrounded by the sealant. The counter substrate is absent over the terminal area. The alignment film is disposed under the sealant on the TFT substrate. An oxide conductive film, disposed under the alignment film, is formed up to the edge of the TFT substrate and is in an electrically floating state.
