Liquid crystal composition and liquid crystal light modulating apparatus

Abstract

A chiral nematic liquid crystal composition that exhibits a cholesteric phase, said chiral nematic crystal composition comprising 55 wt % to 90 wt % of a nematic liquid crystal composition that comprises, as main components thereof, a liquid crystal ester compound and a liquid crystal pyrimidine compound, wherein said liquid crystal ester compound does not include a tolan skeleton therein and said liquid crystal pyrimidine compound includes a fluorine atom therein; and 10 wt % to 45 wt % of at least one chiral agent. A liquid crystal light modulating apparatus comprising a pair of substrates at least one of which is transparent; and the chiral nematic liquid crystal composition disposed between the substrates.
