Abstract
Abstract A liquid crystal apparatus includes: (a) a liquid crystal panel having a longitudinal direction and containing therein a chiral smectic liquid crystal comprising plural layers of liquid crystal molecules aligned to have a common layer normal, each layer being composed of a plurality of liquid crystal molecules, each liquid crystal molecule being oriented to one of plural stable orientation states in the absence of an electric field; and (b) a panel supporting means comprising two fixing axes which extend in parallel with the longitudinal direction of the liquid crystal panel and fix the peripheral sides of the liquid crystal panel, the fixing axes forming an intersection angle θ 1 in the range of 0-25 degrees with the common layer normal.
