Abstract

PURPOSE: To provide a liquid crystal compsn. contg. predetermined wt% in total of two differnt 4-substd.-4'-cyanobiphenyl derivatives and a pyrimidine dierviative, which shows good contrast because of no absorption in visible rays and has a sufficiently practical liquid crystal temp. range.
CONSTITUTION: The liquid crystal compsn. contains more than 80wt% in total of a cyanobiphenyl derivative (component A) such as p-n-pentyl-p'-cyanobiphenyl, a pyrimide derivative (compnent B) such as p-n-pentyl-pyrimidine-p'-cyanobenzene, and p-(2-methyl butyl)-p'-cyanobiphenyl (component C). In the compsn. the amts. of the components A, B and C are 30W80wt%, 7W50wt% and 7W40wt%, respectively. Using this compsn. a liquid crystal display device more suitable for matrix display is obtd. and a Ch-N phase transfer type display device using grandjean structure can be fabricated.
