Abstract
The present invention is directed to compounds of the following General Formula I. The cyclopropyl-bearing liquid crystal compounds of Formula I of the present invention have a positive or negative dielectric anisotropy (Δ∈), an appropriate optical anisotropy (Δn), an appropriate clearing point (CP), good low-temperature miscibility with other liquid crystals, a low rotary viscosity, and good UV stability and high-temperature thermal stability, and therefore have good use value. The compounds of the present invention can be used for preparing positive and negative liquid crystal compositions and can also be employed in passive and active matrix displays.
