摘要: Described are media for liquid-crystal applications where the media include a mixture of polar compounds of positive dielectric anisotropy. The mixtures include one or more compounds of the formula I in which: R1 is a halogenated or unsubstituted alkyl or alkoxy radical having from 1 to 15 carbon atoms, where one or more CH2 groups in these radicals are optionally, independently of one another, replaced by —C≡C—, —CH═CH—, —O—, —CO—O—or —O—CO— in such a way that O atoms are not linked directly to one another; X is F, Cl, CN, a halogenated alkyl radical, a halogenated alkenyl radical, a halogenated alkoxy radical or a halogenated alkenyloxy radical having 1 to 6 carbon atoms; and L1 and L2 are each, independently of one another, H or F. It being provided that the media exhibit a TN threshold of below 1.3V.
