    摘要： The present invention relates to a liquid-crystalline medium based on a mixture of polar compounds of positive or negative dielectric anisotropy which is characterised in that it comprises one or more compounds of the general formula I in which R1 and R2 are each, independently of one another, identically or differently, H, an alkyl radical having from 1 to 12 carbon atoms which is unsubstituted, monosubstituted by CN or CF3 or at least monosubstituted by halogen, where, in addition, one or more CH2 groups in these radicals may each, independently of one another, be replaced by —O—, —S—, —CH═CH—, —C≡C—, —CO—, —CO—O—, —O—CO— or —O—CO—O— in such a way that O atoms are not linked directly to one another, to the use thereof for electro-optical purposes, and to electro-optical display devices which contain this medium.

    摘要翻译： 本发明涉及一种基于正或负介电各向异性的极性化合物的混合物的液晶介质，其特征在于其包含一种或多种通式I的化合物，其中R 1， 和R 2各自彼此独立地相同或不同地是H，具有1至12个碳原子的烷基，其被未取代的，被CN或CF 3单取代的 >或至少被卤素单取代，此外，这些基团中的一个或多个CH 2个基团可各自独立地被-O - ， - S - ， - CH -CH-，-C≡C-，-CO-，-CO-O-，-O-CO-或-O-CO-O-，使得O原子彼此不直接相连， 其用于电光目的，以及含有该介质的电光显示装置。
