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 while driving one of the scanning electrodes. CONSTITUTION:The means is provided while makes the preparations for driving the scanning electrodes and signal electrodes by combining the driving waveforms while one of the scanning electrodes is driven. For example, the scanning electrodes are driven by combining some wavefom and its inverted waveforms in a driving period across a halt period to eliminate driving energy in total and thus the stable state of the optical modulating element is secured. Further, plural waveforms are combined without no halt period interposed to generate a completely new proper waveform. Consequently, when the display device is constituted by using the optical modulating element having bistability to an electric field, the proper driving control is performed while its characteristics are utilized effectively.
