The invention relates to a liquid-crystalline medium for electrooptical display elements based on the ECB effect, containing two components A and B which themselves comprise one or more individual compounds, component A having clearly negative dielectric anistropy and giving the liquid-crystalline phase a dielectric anistrophy of .ltoreq.-0.3, and component B having pronounced nematogeneity and a viscosity of not more than 30 mPa.s at 20.degree. C., characterized in that component A contains one or more compounds containing a structural element ##STR1##
该发明涉及一种用于基于ECB效应的电光显示元件的液晶介质,其中包含两种成分A和B,它们本身包括一个或多个个体化合物,成分A具有明显的负介电各向异性,并使液晶相的介电各向异性为≤-0.3,成分B具有明显的向列型特性,并且在20摄氏度时粘度不超过30mPa.s,其特征在于成分A含有一个或多个含有结构元素的化合物。
