Abstract

PURPOSE: Titled composition, having reduced response time keeping the upper limit of liquid crystal temperature within a practical range, and useful for a TN indicator, which is prepared by the addition of 4-cyclopentyl-n-Alkylbenzene, as a viscosity depressant, to a liquid crystal compound.
CONSTITUTION: (i) 85W97wt% of a liquid crystal compound is mixed with (ii) 3W15wt% of 4-cyclopentyl-n-Alkylbenzene of formula I (wherein R is 1W5C alkyl; formula II is cyclopentyl) (e.g., 4-cyclopentyl-methylbezene, 4-cyclopentel-n- pentylbenzene), and the resulting mixture is heated with agitation until it is molten, to obtain a nematic liquid crystal composition. Component (i) is a mixture of trans-4-n-propyl-(4'-cyanophenyl)-cyclohexane, trans-4-n-pentyl-(4'-cyanophenyl)- cyclohexane, and trans-4-n-heptyl-(4'-cyanophenyl)-cyclohexane, etc.
