  Trans-2-phenyl-5-trans-4'-alkylcyclohexyl-1,3-dioxane derivatives represented by the general formula: ##STR1## wherein R is a linear alkyl group of 1 to 10 carbon atoms, A is a single covalent bond or a --CH.sub.2 CH.sub.2 -- group, X is F or CN, Y is F if X is CN or Y is H or F if X is F, and the cyclohexane ring and the 1,3-dioxane ring are trans isomers. The 1,3-dioxane derivatives have large positive dielectric constant anisotropy (.DELTA..epsilon.), small birefringence (.DELTA.n) and have good compatibility with other liquid crystal compounds. The dioxane derivatives may be included in liquid crystal compositions for improved display devices having a low threshold voltage, a low driving voltage and a wide visual angle.

  Liquid crystalline compounds containing the -CH2CH2-C=C- interring linkage between cyclohexane and benzene rings belonging to four homologous series have been prepared. Their mesogenic, viscous, dielectric optical, and dielectrooptical properties were investigated and compared with the properties of analogous compounds with the -CH2CH2- or -C=C- bridge groups. The mesogenic and physical properties of the compounds with the -CH2CH2-C=C- linkage group are intermediate between properties of the compounds with -C=C- and the properties of the compounds with -CH2CH2- group, except that their clearing points are lower and viscosity is higher.
