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, e.g., biphenyl-based compounds, a pyrimidine-based compound, an ester compound, etc.
CONSTITUTION: (A) Preferably 30W85wt% of two or more compounds selected from 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 or straight-chain alkoxy; R2 is n-C5H11) is blended with (B) preferably 5W45wt% of a pyrimidine-based compound shown by the formula III (R3 is 4W8C straight-chain alkyl, etc.), (C) preferably 5W35wt% of an ester compound shown by the formula IV or V (R4WR7 are 1W8C straight-chain alky, etc.), and (D) preferably 2W15wt% of a phenylcyclohexane-based compound shown by the for mula VI (R8 is 3W7C straight-chain alkyl), to give the desired composition.
EFFECT: A dynamic drive of 3V (or 2.8V) at 1/3 bias and 1/3 duty is possible.
