Abstract
PURPOSE:To obtain a uniform display and driving characteristic by using a ferroelectric liquid crystal which is wide in the width of the transition temp. at which a ferroelectric liquid crystal material changes from an isotropic liquid to a state and with which the transition takes place slowly. CONSTITUTION:The transition temp. width of the liquid crystal is wide and therefore, the formation of a uniform monodomain is not possible at the time when the liquid crystal material transforms from the isotropic liquid state to the mesomorphic state. The liquid crystal has the multidomain state in which the many microdomains gather in such a case. Since the orientation defects of the liquid crystal are relieved by the boundary of the domains in such multidomain state, the generation of zigzag defects, etc., is obviated over the entire part of the liquid crystal electro-optic device. The microdomains are internally in the good monodomain state. The difference in the display or driving characteristic of the liquid crystal in the respective microdomains is thereby eliminated and the display or driving characteristic uniform over the entire part of the device is obtd.
