ABSTRACT:
A method of driving an antiferroelectric liquid crystal device, comprising a pair of substrates, each providing electrodes, insulating films and orientation films in this order thereon, which is arranged so as to be opposed to each other and interposes an antiferroelectric liquid crystal composition between the orientation films, wherein electrode on either one of the substrates comprises a plurality of scanning electrodes and a plurality of signal electrodes in a matrix form and a thin film transistor at each point of intersection of the matrix, which comprises transmitting a signal from the scanning electrode to the thin film transistor to turn on and synchronistically applying a zero or positive selective voltage waveform corresponding to a desired display to the signal electrode of odd-numbered frames and a zero or negative selective voltage waveform corresponding to the desired display to the signal electrode of even-numbered frames.
