An improved method of filling a liquid crystal device with a blended ferroelectric liquid crystal material is disclosed. The method includes the step of disposing the blended ferroelectric liquid crystal material in an inner space formed in the liquid crystal device, with the temperature of the blended liquid crystal being maintained during the disposing step at a temperature higher than the transition temperature of any constituent of the blended liquid crystal material such that the blended liquid crystal material is transformed in its isotropic phase.
