Patent ID: 7233306

Claim:
A liquid crystal device comprising: a first substrate including a first electrode on a first face thereof; a second substrate including a second electrode on a second face thereof, wherein said second substrate and said first substrate are sealed spaced apart so that said first and second substrates face each other; a liquid crystal material having spontaneous polarization filled in a space between said first and second substrates; a first voltage generating circuit for supplying a voltage to said first electrode; and a data signal circuit for supplying a data pulse to said second electrode, wherein a voltage across said liquid crystal between said first and second electrodes is offset to either a single, positive or negative constant level from a reference voltage of said device at all times during operation, except during said data pulse application when an image is displayed; wherein the value of the offset has the same polarity at all times during operation except during signal application; and wherein the offset is applied automatically at all times during operation except during signal application.
