PURPOSE:To shorten the writing time of one picture and to perform faster display operation by perform erasing operation for a part corresponding to plural scanning electrodes before information is written and displaying the information in black or white as one color of binary display. CONSTITUTION:A voltage is impressed between plural scanning electrodes 20 and a signal electrode 22 at the same time and dipoles of liquid crystal molecules between them are all oriented in one direction to enter a white or black erasure state. Then, those plural scanning electrodes 20 are scanned, one by one, in order to apply an information signal voltage synchronized with the scanning to the signal electrode 22, and the direction is inverted according to an information signal indicating the direction of bipoles to make a black or white display, thereby placing plural scanning electrodes in a display state. Then, plural following scanning electrodes 20 are put in the same operation to put all scanning electrodes 20 in this operation, thereby displaying one image plane.
