    • A liquid crystal display according to this invention has a pair of transparent electrodes, a non-chiral smectic liquid crystal therebetween, a polarizer and an analyzer which are attached to the electrodes. The smectic layers are perpendicular to the electrodes and the liquid crystal has a twisted structure where the twist angle is twice the molecular tilt angle. In this configuration, the molecular director is forced to continuously rotate along the cone surface formed by the requirement that the molecules are tilted with respect to the layer normal and pinned at the surfaces. The basic principles of the optical modulation in the present invention are similar to those in twist nematic liquid crystal structures.
    • 根据本发明的液晶显示器具有一对透明电极,它们之间的非手性近晶液晶,偏振器和分析器,其附接到电极。 近晶层垂直于电极,液晶具有扭转结构,其扭转角是分子倾斜角的两倍。 在这种结构中,分子导向器被迫沿着锥形表面连续旋转,锥形表面通过分子相对于层法线倾斜并被固定在表面上的要求而形成。 本发明的光调制的基本原理与扭曲向列型液晶结构相同。
