    • In a liquid crystal display in which a liquid crystal having spontaneous polarization is sandwiched between substrates, liquid crystal alignment which achieves a wide viewing angle and hardly causes alignment destruction is readily formed. A common electrode is formed by a pair of meshed comb electrodes, and rubbing alignment is performed in the logitudinal direction of teeth of these comb electrodes. When the liquid crystal material transits from a nematic phase or an isotropic phase to a chiral smectic C phase, a positive DC voltage, for example, is applied between a pixel electrode and one of the comb common electrodes, and a negative voltage is applied between a pixel electrode and the other comb common electrode. This readily accomplishes liquid crystal alignment in which smectic layers bend horizontally with respect to the substrate surface in space portions between the interdigitated teeth of the comb electrodes.
    • 在具有自发极化的液晶夹在基板之间的液晶显示器中,容易形成实现宽视角并且几乎不引起取向破坏的液晶取向。 公共电极由一对啮合的梳状电极形成,并且在这些梳状电极的齿的纵向上执行摩擦取向。 当液晶材料从向列相或各向同性相转移到手性近晶C相时,例如在像素电极和梳状公共电极之间施加正的直流电压,并且在两个梳状公共电极之间施加负电压 像素电极和另一个梳状共用电极。 这容易实现液晶对准,其中近晶层相对于梳电极的叉指齿之间的空间部分中的基板表面水平弯曲。
