Abstract
A display device, which is adapted for time-division driving and is free from occurrence of crosstalk, includes a pair of substrates which are arranged to be opposite to each other and at least one of which is transparent, electrodes provided respectively on surfaces of the substrates facing each other, and a material which is sandwiched between the electrodes and the light transmitting quantity of which is changed by an electric field applied between the electrodes. The electrodes formed on the surfaces of the substrates facing each other constitute scanning electrodes and signal electrodes which intersect each other to form display portions. The signal electrodes constitutes independent electrodes formed independently of each other in units of display portions. Outside leads of the respective independent electrodes are passed through the substrate provided with the electrodes and are led out to the back surface of the substrate.
