    摘要： The invention relates to a liquid-crystalline medium based on a mixture of polar compounds of positive dielectric anisotropy, containing at least one compound of the general formula I wherein R1-R4 may each, independently of one another, be an alkyl or alkenyl radical having up to 12 carbon atoms which is unsubstituted, monosubstituted by CN or CF3 or at least monosubstituted by halogen, where one or more CH2 groups in these radicals may also, in each case independently of one another, be replaced by —O—, —S—, —CO—, —CO—O—, —O—CO— or —O—CO—O— in such a way that O atoms are not linked directly to one another, and —A— is 1,4-phenylene, in which, in addition, one or two CH groups may be replaced by N, 2,3-difluoro-1,4-phenylene, 2-fluoro-1,4-phenylene, 3-fluoro-1,4-phenylene or a single bond.

    摘要： A liquid-crystalline medium containing a mixture of polar compounds of positive dielectric anisotropy. The mixture contains one or more compounds of formula I in which: R is H, an alkyl or alkenyl radical having 1 to 15 carbon atoms which is unsubstituted, monosubstituted by CN or CF3 or at least monosubstituted by halogen, where one or more CH2 groups in these radicals are optionally, in each case independently of one another, replaced by —O—, —S—, —CO—, —CO—O—, —O—CO— or —O—CO—O in such a way that O atoms are not linked directly to one another; is a trans-1,4-cyclohexylene ring, in which one or two CH2 groups are optionally replaced by —O— and/or —S—, or a cyclohexenylene ring; Y is halogenated alkyl, halogenated alkenyl, halogenated alkoxy or halogenated alkenyloxy having 1 to 6 carbon atoms; Z is —OCH2—, —CH2CH2—, —CH═CH—, —CF2O—, —OCF2—, —C2F4— or a single bond; and n is 1 or 2. And the mixture contains one or more dioxane compounds of the following formula wherein R0 is n-alkyl, oxoalkyl, fluoroalkyl or alkenyl, in each case having 1 to 7 carbon atoms; and X0 is F, Cl, halogenated alkyl, alkenyl or alkoxy having 1 to 6 carbon atoms.
