In the method for driving a liquid crystal optical apparatus of the present invention, the initialization signals are supplied, for the sequential display, to the scanning electrode groups of display elements, the selection signal is then supplied following such initialization signals, after initializing the ferroelectric liquid crystal to the saturated reverse response condition depending on a voltage difference between the desired signal supplied to the control electrode group and such initialization signal, a pulse group for initializing the liquid crystal up to the response condition less than the threshold value for obtaining such response condition is applied, the response control pulse group for attaining the desired response condition of the ferroelectric liquid crystal is subsequently applied depending on the voltage difference between the selection signal supplied and such desired signal, the scanning period of selection signal can be shortened by obtaining the desired response condition through cooperation of the initialization pulse groups and response control pulse groups, and the write period of single display frame can be curtailed remarkably by previous initialization of the next line simultaneously with application of the selection signal.
