Abstract
In order to provide a liquid crystal display device of high display quality by improving the evenness of a liquid crystal cell gap in a marginal frame portion of a liquid crystal element suited to a narrow frame, the liquid crystal display device is provided with a pair of liquid crystal display element substrates having a liquid crystal sandwiched therebetween, and a plurality of liquid crystal driving elements connected to conductors formed on each of the liquid crystal display element substrates, for driving the liquid crystal. Each of the liquid crystal display element substrates includes a plurality of display electrodes wired in parallel, a plurality of parallel terminal electrodes, mutually parallel oblique straight wiring electrodes, and a plurality of dummy electrodes generally parallel to the terminal electrodes. Each of the conductor electrodes is formed so that the variation in wiring resistance between a central portion and an end portion of each of the liquid crystal driving circuits and the variation in area occupation ratio per unit area of the wiring disposed below the sealing material are smaller than predetermined allowable values, respectively.
