摘要： Disclosed herein is an optically active compound and a ferroelectric liquid crystal composition produced therefrom. The optically active compound has a fluorine atom introduced into the core nucleus so that it does not take on the smectic phase of a high order except for the smectic A phase and smectic C phase and which has carbonyl groups (for dipole) at adequate positions so that it exihibits greater spontaneous polarization. The ferroelectric liquid crystal composition is composed of a chiral component (including the optically active compound) and a non-chiral component, and hence it is superior in response performance.

摘要： A liquid crystal display device having fast response characteristics and enabling analog gray-scale display is provided. The liquid crystal display device is formed of a liquid crystal material having the chiral smectic C phase. The projection component on the substrates of the axial direction of a cone delineated by a liquid crystal molecule, and the projection component on the substrates of the axial direction of the liquid crystal molecule itself, are adapted to be coincident with the processing direction for uniaxial orientation of the substrates, this state being monostabilized as the initial state. On application of an electrical field, the liquid crystal molecule is rotated along the cone and the apparent tilt angle as viewed on the substrate surface is continuously changed in accordance with the strength of the applied electrical field. The intensity of the transmitted light is increased continuously with increasing tilt angle to obtain the continuous gray-scale or analog gray-scale.
