Abstract
PURPOSE: The titled composition useful for an electronic calculator, etc., capable of exhibiting a nematic liquid crystal phase in a wide temperature range near at room temperatures, making the severe dynamic drive possible, obtained by blending specific compounds of biphenyl-based compounds, pyrimidine-based compounds, an ester compound, etc.
CONSTITUTION: (A) Preferably 30W85wt% of two or more compounds selected form the group consisting of biphenyl-based compounds shown by the formula I and/or terphenyl-based compounds shown by the formula II (R1 is 3W8C straight- chain alkyl, etc.; R2 is n-C5H11) is blended with (B) preferably 5W45wt% of pyrimidine-based compound shown by the formula III (R3 is 4W8C stright-chain alkyl, etc.), (C) preferably 5W35wt% of an ester compound shown by the formula IV or V (R4WR7 are 1W8C straight-chain alkyl, etc.), (D) preferably not more than 25wt% of a pyrimidine-based compound shown by the formula VI (R8 is n-C4H9), and (E) preferably not more than 10wt% of a compound (e.g., di-n-hexyl ether, etc.) not exhibiting a liquid crystal phase by itself, capable of preventing viscosity increase at low temperatures (isotropic dopant), to give the desired composition.
