LIQUID CRYSTAL DISPLAY DEVICE

摘要

PURPOSE: To make a liquid crystal display device to be provided with the function of an orientation improvement in the liquid crystal display device using smectic liquid crystal. CONSTITUTION: The picture display of a liquid crystal panel 1 is performed by impressing a scanning signal on row electrodes (Y1 to Yn) of the liquid crystal panel 1 from a row electrode driving circuit 23 and by impressing a data signal on column electrodes (X1 to Xm) of the liquid crystal panel 1 from a column electrode driving circuit 24 based on the signal from a control circuit 22. At this time, at the time of performing an aging for the orientation improvement of liquid crystal, the scanning signal and the data signal are changed over to voltage signals for the aging by operating a switch circuit 26.
