Abstract (en)
A driving method for a liquid crystal device of the type comprising a pair of oppositely disposed substrates each provided with an electrode, a chiral smectic liquid crystal disposed between the substrates to form a plurality of pixels and to be placed in a monostable state under no voltage application, and a plurality of active elements each of which is provided to an associated pixel and is connected with an associated electrode so as to effect a matrix drive of the liquid crystal device includes a step of driving the liquid crystal device so that the liquid crystal is tilted from the monostable state to provide a maximum tilt angle in actual drive smaller than a saturation tilt angle. The drive method is effective in suppressing burning or alignment state change of the chiral smectic liquid crystal, thus improving display characteristics. <IMAGE> <IMAGE>
