ABSTRACT:
A liquid crystal optical device has a ferroelectric liquid crystal layer held in a gap defined by at least a pair of electrodes, wherein the crystal pixel has a time constant. The liquid crystal device also has a parallel circuit having a time constant greater than the time constant of the liquid crystal pixel and less than a field period for giving a gradation change to the pixel by repeated application of a gradation signal.
