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 &#x2212;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 &#x2212;20&#xb0; 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. 

Liquid crystal composition and application thereof

This invention relates to liquid crystal compound of formula I containing a difluoromethyleneoxy linking group that hydrogen substituted by deuterium and therefore being very suitable for formulating a liquid crystal mixture. A liquid crystal mixture containing such type of liquid crystal compounds can be applied in various display devices.
