The present invention relates to a liquid crystal cell having a plural number of electrode pairs arranged on both sides of the liquid crystal matter so as to be opposed to each other, being characterized in that a pulse wave generating device for generating the first pulse wave with smaller amplitude than the threshold valve for lighting the liquid crystal and the second pulse wave with larger amplitude than the threshold value for lighting the liquid crystal in reversed phase to each other and a gate device for selectively applying the outputs of the pulse wave generating device to each electrode of the liquid crystal cell in accordance with the input signal are provided. Thus only the voltage between the selecting electrodes is highter than the threshold value. An input change over device is provided so as to change over the input signal group in a time dividing way in such a manner that a plural number of dots can be displayed visually at the same time, as a result, the wiring is simplified.
