Patent ID: 7258903

Claim:
A method of generating an electrooptical effect comprising applying a voltage to a liquid crystal device containing a liquid crystal composition, said composition comprising: at least 30 weight %, based on the total weight of the composition, of a component (α) containing one or more compounds having a dielectric anisotropy Δε of at least 25, wherein at least 25 weight %, based on the total weight of the composition, of said compounds have a dielectric anisotropy Δε of at least 40; and a component (δ) containing one or more compounds each having a ratio of γ 1 /T NI K of 0.51 mPa·s/K or less, a clearing point T NI of at least 100° C. and a rotational viscosity γ 1 of not more than 190 mPa·s, wherein γ 1 is the rotational viscosity at 20° C. in mPa·s and T NI K is the clearing point in degrees Kelvin.
