Abstract
Disclosed is a liquid crystal composition and use thereof. The liquid crystal composition comprises components a, b and c; wherein component a is selected from one of the compounds represented by formula I; component b is a liquid crystal composition having a dielectric anisotropy of greater than 3; and component c is a liquid crystal composition having a dielectric anisotropy of −3 to 3. The liquid crystal composition has a high contrast ratio property, and has a low change rate at a low temperature, that is, the decrease of contrast ratio at a low temperature (such as −20° C.) is smaller as compared to a normal temperature. The composition has suitable properties with regard to practical applications, including a broader nematic phase range, an appropriate dielectric anisotropy, optical anisotropy and operating voltage, an excellent response time, a high electrical resistivity and voltage holding ratio, a low rotary viscosity, etc.
