ABSTRACT:
The liquid crystalline material of the present invention comprises a compound represented by the following structural formula (1), compounds represented by the structural formulas (1) and (2), compounds represented by the structural formulas (1) and (3), or compounds represented by the structural formulas (1), (2) and (3) in an amount of 90% by weight or more of the total amount of liquid crystalline components contained therein: ##STR1## wherein R represents a linear alkyl group, C.sub.n H.sub.2n+1 in which n is 3, 4, 5, 6 or 7, A represents --CH.sub.2 CH.sub.2 -- or direct bond (--) without --CH.sub.2 CH.sub.2 --, and B represents --CH.sub.2 CH.sub.2 -- or direct bond (--) without --CH.sub.2 CH.sub.2 --. Further, under the above conditions, the components are blended so that the nematic-isotropic transition temperature of the liquid crystalline material can be 55.degree. C. to 75.degree. C. A liquid crystal display panel of TN type obtained by using the thus-obtained liquid crystalline material is operable with a low voltage of 2.5 V or lower. A display panel of which power consumption is low can thus be attained.
