Abstract: 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.
