Abstract

PURPOSE:To enable proper driving control while utilizing the characteristics of an optical modulating element effectively by providing a means which makes preparations for driving scanning electrodes and signal electrodes by combining plural driving waveforms with a halt period interposed while driving one of scanning electrodes. CONSTITUTION:The means is provided which makes the preparations for driving the scanning electrodes and signal electrodes by combining the driving waveforms with the halt period interposed while one of the scanning electrodes is driven. In the halt period, some waveform and its inverted waveform, for example, are outputted in the driving period of the scanning electrodes to drive the scanning electrodes, and consequently the total driving energy is reduced to 0 to secure the stable state of the optical modulating element. Consequently, when the display device is constituted by utilizing the optical modulating element having bistability to an electric field, the proper driving control is performed while its characteristics are utilized effectively.
