<p>PURPOSE:To display an image plane consisting of many picture elements at a high speed by applying a scanning signal and a display signal to the drain or source and gate of an FET corresponding to a picture element where ferroelectric liquid crystal is charged respectively and performing time-division drive, and refreshing a next line simultaneously with the writing. CONSTITUTION:Ferroelectric liquid crystal which has a bistable state to an electric field is charged between picture element electrodes which have FETs corresponding to respective picture elements and a counter electrode, thus constituting the liquid crystal element. Drains or sources of the FETs which constitute an active matrix are connected to scanning electrodes 6, gates are connected to display electrodes 7, and the counter electrode is a common electrode. A scanning signal is applied to an electrode 6 and a display signal is applied to a display electrode 7 for the time-division drive, and the next line is refreshed into the 2nd orientation state while a specific scanning signal is applied to a scanning line and a specific display signal is applied to a selected display signal line to write a display state based upon the 1st orientation state. Thus, a display of an image plate consisting of many picture elements is made at a high speed.</p> |
