ABSTRACT:
A display apparatus includes: (a) a liquid crystal device comprising scanning electrodes, data electrodes and a ferroelectric liquid crystal disposed between the scanning electrodes and data electrodes, the scanning electrodes and data electrodes being disposed to intersect each other so as to form an electrode matrix and provide a display surface covering the electrode matrix, (b) first means for applying a scanning selection signal to the scanning electrodes and applying data signals to the data electrodes in synchronism with the scanning selection signal, and (c) second means for dividing the display surface into an effective display region and a non-display region and controlling the first means so as to apply a scanning selection signal to a scanning electrode covered by the non-display region in a shorter cycle than the application of a scanning selection signal to scanning electrodes covered by the effective display region.
