ABSTRACT:
A display apparatus disposes a ferroelectric liquid crystal between a group of scanning electrodes and a group of data electrodes constituting an electrode matrix, and provides a driver that applies a scanning signal to the scanning electrodes and applies data signals to the data electrodes in synchronism with the scanning signal. The driver is controlled as to divide the scanning electrodes into a plurality of blocks each comprising a plurality of scanning electrodes and select the scanning electrodes with skipping of at least one scanning electrode apart so that starting scanning electrodes in neighboring blocks from which the skipping-selection of scanning electrodes is started in each block of the scanning electrodes have mutually different positional ranks respectively in the neighboring blocks, whereby flickering caused by either scanning drive or by repetition of black and white signals is effectively suppressed while the observability of a motion picture is retained.
