Abstract
A liquid crystalline compound of the general formula ##STR1## wherein ##STR2## represents ##STR3## R and R', independently from each other, represent a linear alkyl group having 1 to 10 carbon atoms, an alkoxymethylene group whose alkoxy moiety has 1 to 10 carbon atoms, a cyano group or a halogen atom, and n and m, independently from each other, represent 0 or 1.
Claims6
A mixed liquid crystalline composition exhibiting a nematic liquid crystal phase and low viscosity, said composition comprising a matrix liquid crystal component and at least one compound which is represented by the general formula ##STR194## wherein R and R', independently from each other, represent a linear alkyl group having 1 to 5 carbon atoms, and the sum of the number of carbon atoms of R and R' is 3 to 7 in an amount effective to reduce the viscosity of the matrix liquid crystal component.
