    • The invention relates to a liquid crystalline medium based on a mixture of polar compounds of positive dielectric anisotropy, consisting of one or more compounds of general formula (I) in which R is H, an unsubstituted, a simply by CN or CF3 substituted or at least simply an halogen-substituted alkyl or alkenyl radical with 1 to 15 C atoms, where one or more CH2 groups in said radicals may be mutually independently substituted by -O-, -S-, (a), -CO-, -CO-O-, -O-CO- or -O-CO-O- in such a way that O atoms are not directly linked together; Y is F, Cl, halogenated alkyl, alkenyl or alkoxy with 1 to 6 C atoms; and L is H or F.
    • 本发明涉及一种基于具有正介电各向异性的极性化合物,其特征在于的混合物的液晶介质,它包含通式(I)其中R是H,未取代的,由CN或CF 3或单取代的一种或多种化合物 通过其中这些基团中的一个或多个CH 2个基团各自独立地被-O - , - S - ,的(a), - CO-,-CO取代卤素,烷基或具有1至15个碳原子,链烯基至少单取代的 -O - , - O-CO-或-O-CO-O-以这样一种方式,O原子不直接彼此相连接的,Y是F,Cl,卤代烷基,链烯基或烷氧基的碳原子数为1〜6, 且L是<1> H或F.
