Abstract
In a liquid crystal display device comprising a pair of opposed electrode-mounted plates and a nematic liquid crystal layer, the electrode terminals are mounted on one plate by transferring the connection of one electrode to the opposite plate without directly contacting the liquid crystal material by interposing an electrically conductive material between the corresponding electrode terminal and the one electrode. In accordance with changes of environment, distinct patterns are obtained by making the front electrode of the liquid crystal display element transparent and the back electrode thereof a partial light-transmissive, mirror-like plane. The life of the liquid crystal element under application of D.C. field is increased by using titanium, zirconium and palladium as an essential component of the negative electrode of said element.
