Abstract

PURPOSE: A liquid crystal composition useful for display elements having improved response properties, capable of exhibiting a nematic liquid crystal phase in a wide temperature range near room temperatures, making the severe dynamic drive possible, obtained by blending specific two kinds of ester compounds with a pyrimidine- based compound.
CONSTITUTION: (A) Preferably 30W85wt% of a low-viscosity chemically stable compound shown by the formula I (R1 is 3W7C straight-chain alkyl) is blended with (B) preferably 5W45wt% of a pyrimidine-based compound shown by the formula II (R2 is 4W8C straight-chain alkyl or straight-chain alkoxy) capable of increasing the positive dielectric anisotropy of a liquid crystal composition, and lowering the operation voltage, and the temperature dependence of the operation voltage, and (C) preferably 5W40wt% of an ester compound shown by the formula III (R3 and R4 are 1W8C straight-chain alkyl or straight-chain alkoxy) having stabilizing action on liquid crystal phase at low temperatures, small dielectric anisotropy and low viscosity to give the desired composition.
EFFECT: A dynamic drive of 3V (or 2.8V) at 1/3 bias and 1/3 duty is possible.
