Abstract

The invention relates to a negative dielectric anisotropic liquid crystal composition and applications thereof. The liquid crystal composition comprises at least one or more compounds represented by the formula I and one or more compounds represented by the formula II. The provided liquid crystal composition has the advantages of low rotary viscosity, large elastic constant, good low temperature inter-solubility, and quick response speed, can be applied to multiple display modes of quick response liquid crystal display, and can obviously improves the display effect of a liquid crystal displayof a VA / MV / PVA / PSVA, IPS or FFS mode.

Description

technical field [0001] The present invention relates to a liquid crystal composition, specifically a nematic liquid crystal composition, specifically, the liquid crystal composition provided by the present invention has negative dielectric anisotropy, more precisely, the present invention The provided liquid crystal composition has a fast response time. Background technique [0002] With the improvement of people's requirements for display effects, curved display, high transmittance, high contrast and other requirements are more and more favored by more consumers, relying on PSVA technology can achieve curved display and high transmittance, high contrast Demand, suitable for large-size panel demand, negative liquid crystal used in FFS mode can improve the transmittance and hard screen of the liquid crystal display, reduce backlight power consumption, increase battery life, and is suitable for mobile display devices such as mobile phones and tablets.
