    摘要: Mixtures of liquid crystal compounds from among different classes of liquid crystal ester compounds are disclosed. The mixtures exhibit freezing points substantially lower than the freezing point of either ester compound alone, so as to provide a substantially improved (widened) smectic C mesomorphic temperature range and protection against freezing or crystallization of liquid crystal material over a range of temperatures at which an electrooptic display device would typically be operated.
