摘要： There is disclosed herein a ferroelectric liquid crystal electro-optical apparatus of the maxtrix type comprising a liquid crystal cell having first and second electrode substrates which include n striped line electrodes and m striped column electrodes, respectively, facing at right angles each other. A ferroelectric liquid crystal is put in therebetween so as to form n by m indication picture elements. Also included in the apparatus a scanning drive device adapted to supply a scanning signal and a data signal to the n striped line electrodes and the m striped column electrodes, respectively. The ferroelectric liquid crystal shows three stable states in accordance with an application voltage and has a light transmittance with a hysteresis sufficient to a dynamic drive in accordance with increase or decrease in the application voltage in a predetermined voltage range. The scanning drive device produces a first combination signal as a signal running to variation from a voltage below a refernece voltage in a predetermined one polarity voltage range to a voltage above the reference voltage and produces a second combination signal as a signal which does not exceed the reference voltage in the range, and supplies a direct-current combination signal between the electrodes after the supply of the first and second combination signal thereto.
