Abstract
Provided is a liquid crystal compound containing 2,3,4-trisubstituted benzene, a liquid crystal composition thereof, and a liquid crystal display element or a liquid crystal display comprising the liquid crystal compound or the liquid crystal composition, wherein the liquid crystal composition has a lower viscosity, can achieve a quick response, and further has a moderate dielectric anisotropy Δε, a moderate optical anisotropy Δn, and high stability to heat and light. The liquid crystal display element or liquid crystal display comprising the liquid crystal composition has the properties of a wider nematic phase temperature range, an appropriate birefringence anisotropy, a very high electrical resistivity, a good ultraviolet resistant property, a high charge retention rate, a low vapor pressure etc., and particularly, the liquid crystal compound or the liquid crystal composition has the advantage of a high light transmittance.
