Abstract

The invention relates to a negative dielectric anisotropy liquid crystal composition and applications thereof. The composition includes at least one compound represented by a general formula I and at least one compound represented by a general formula II. The compounds represented by the general formula I are bis(cyclohexenyl) compounds and have extremely low rotational viscosity and excellent intersolubility. The compounds represented by the general formula II are compounds containing cyclohexenyl and a 2,3-difluoro type structure, have high negative dielectric anisotropy and low rotational viscosity, and can effectively improve negative dielectric anisotropy of the composition. The composition has low rotational viscosity and can be used for fast-response liquid crystal display apparatuses of a plurality of modes.
