Liquid crystal device and method for driving the same using ferroelectric liquid crystal and FET's

摘要

A driving method for a liquid crystal device of the type comprising a plurality of FET's each having a gate and a first and a second terminal other than the gate, a first base plate having therein a plurality of picture element electrodes each corresponding to an FET and connected to the first terminal of the FET, a second base plate having thereon counter electrodes opposite to the picture element electrodes, and a ferroelectric liquid crystal having first and second orientation states and sandwiched between the first and second base plates; the driving method comprising a first phase of forming an electric field between a first terminal and a second terminal of an FET to result in the first orientation state of the ferroelectric liquid crystal, and a second phase of forming an electric field of the polarity opposite to that of the electric field applied in said first phase between a first terminal and a second terminal of an FET to result in the second orientation state of the ferroelectric liquid crystal; the first and second phases being respectively carried out in synchronism with the application of a signal for turning on the gates of the FET' s respectively involved in the first and second phases.
