  • Liquid crystal display
    Patent number: 7068339
    Abstract: In order to provide a liquid crystal display causing no unevenness of the cell gap and preventing the occurrence of non-uniformity of a display in spite of a conductive material, for electrically connecting two substrates, provided in an area inside a sealant, the liquid crystal display has a configuration that a liquid crystal panel has a liquid crystal layer between two transparent substrates which are adhered to each other by a sealing adhesive and a conductive material is formed in a spot form along the liquid crystal layer side of the sealing adhesive so as to electrically connect opposing electrode connecting terminals to opposing common electrodes formed on the transparent substrates.
