ABSTRACT:
A liquid crystal apparatus, includes: a) a liquid crystal device comprising an electrode matrix composed of scanning electrodes and data electrodes, and a ferroelectric liquid crystal showing a first and a second orientation state; and b) a driving means including: a first drive means for applying a scanning selection signal to the scanning electrodes two or more scanning electrodes apart in one vertical scanning so as to effect one picture scanning in plural times of vertical scanning, said scanning selection signal having a voltage of one polarity and a voltage of the other polarity with respect to the voltage level of a nonselected scanning electrode, and a second drive means for applying to a selected data electrode a voltage signal which provides a voltage causing the first orientation state of the ferroelectric liquid crystal in combination with the voltage of one polarity of the scanning selection signal, and applying to another data electrode a voltage signal which provides a voltage causing the second orientation state of the ferroelectric liquid crystal in combination with the voltage of the other polarity of the scanning selection signal.
