A liquid crystalline medium comprises a mixture of polar compounds having positive or negative dielectric anisotropy containing at least one linear substituted aryl-cyclohexyl compound. A liquid crystalline medium (I) comprises a mixture of polar compounds having positive or negative dielectric anisotropy containing at least one compound of formula (1). R<1> = 1-12C alkyl, optionally mono-substituted by CN or CF3 or optionally multiply substituted by halogen whereby two non-neighboring CH2 groups are replaced by -O- , -S-, 1,4-cyclobutane, -CH=CH-, -CC-, -CO-, -CO-O- or -O-CO-O-; A = formula (1a)-(1g); Z<1>,Z<2> = -CF2CF2- or a single bond whereby Z<1> is not Z<2>; X = F, Cl, CN, NCS, SCN, SF5 or 1-6C alkyl, halogenated alkyl, halogenated alkenyl, halogenated alkoxy or halogenated alkenyloxy; u = 0 or 1; v = 0 or 1 An Independent claim is also included for a liquid crystal display containing the liquid crystalline medium (I).
