摘要： The invention relates to a high dielectric anisotropy liquid crystal compound which is a pyridyl derivative with substituents of electrons push-pull effect. Furthermore, the high dielectric anisotropy liquid crystal compounds are colorless and have high thermal and photo stability as well as high compatibility in a liquid crystal host. A liquid crystal composition containing the high dielectric anisotropy liquid crystal compound can reduce threshold voltage of cholesteric reflective displays, thus saving power and extending lifetime of driver ICs.
