| abstract |
The invention discloses a liquid crystal composition with positive dielectric anisotropy, which comprises: one or more compounds of general formula I; one or more compounds of general formula II; and one or more compounds of general formula Compounds of III. The invention also discloses a liquid crystal display device comprising the liquid crystal composition with positive dielectric anisotropy of the invention. The liquid crystal composition provided by the invention has the advantages of high clearing point, good mutual solubility at low temperature, fast response, small LC light leakage, high contrast, high transmittance, etc., and can take into account the contrast while meeting the requirements of large dielectric, low cell thickness, and fast response , especially suitable for liquid crystal display elements driven by active matrix thin film transistors (AM-TFT). |
