Abstract

A liquid crystal composition includes at least one compound of general formula F and at least one compound of general formula N. A liquid crystal display device includes the liquid crystal composition. The liquid crystal composition has a larger K value, a smaller rotational viscosity, a higher VHR value, a longer low temperature storage time and a shorter response time while maintaining an appropriate clearing point, an appropriate optical anisotropy, and an appropriate absolute value of dielectric anisotropy, such that the liquid crystal display device including the liquid crystal composition has a better contrast, a wider temperature range for application, a faster response speed, a better contrast and a higher reliability.
