Abstract

PURPOSE: To provide titled liquid crystal compsn. useful as a TN display element in which response time is short, by a method wherein a 4-n-alkyl-4'-n-alkyl biphenyl and a 4-n-alkyl-4'-n-alkoxy biphenyl are added to a liquid crystal cpd.
CONSTITUTION: (B) 5W30wt% of a mixt. of (i) a 4-n-alkyl-4'-n-alkyl biphenyl of formula I (wherein m, n are 1W5) such as 4-methyl-4'-methyl-biphenyl and (ii) a 4-n-alkyl-4'-n-alkoxy biphenyl of formula II such as 4-n-ethyl-4'-n-ethoxy-biphenyl, are added to (A) 70W95wt% of a nematic liquid crystal cpd. The mixt is heated until the mixt is fused, and stirred to obtain titled compsn. The weight ratio of the component (i) to the component (ii) is pref. 1:0.3W2.
