  • Lateral trifluoromethyl-containing liquid crystal compound, liquid crystal mixture and display device
    Patent number: 10975306
    Abstract: Provide are a liquid crystal compound represented by formula I, and a liquid crystal mixture comprising the compound A lateral trifluoromethyl-containing liquid crystal compound having the structural characteristics of Formula I not only has a negative dielectric anisotropy (??), an appropriate optical anisotropy (?n), a higher clearing point (CP), a prominent low-temperature miscibility with other liquid crystals, and a low rotary viscosity (?1), but also has a good stability to UV and high temperatures, particularly, a negative dielectric anisotropy. Same can be applied to the formulation of liquid crystal compositions of positive and negative types, and it is particularly prominent that same has the advantages of a good solubility at low temperatures and a high transmittance.
    Type: Grant
