Abstract

PURPOSE: The titled composition 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 biphenyl-based compounds with a biphenylcyclohexane-based compound and an ester compound.
CONSTITUTION: (A) Preferably 30W90wt% 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) a biphenylcyclohexane-based compound shown by the formula III (R3 is R2), (C) preferably 2W15wt% of a phenylcyclohexane-based compound shown by the formula IV (R4 is 3W7C straight-chain alkyl), and (D) preferably 5W35wt% of an ester compound shown by the formula V or VI (R5WR8 are 1W8C straight-chain alkyls or straight-chain alkoxy), to give the desired composition.
EFFECT: A dynamic drive of 3V (or 2.8V) at 1/3 bias and 1/3 duty is possible.
