    摘要： Liquid-crystalline medium which comprises at least one compound of the formula I, in which R1 and R1* each, independently of one another, denote an alkyl or alkoxy radical having 1 to 15 C atoms, where, in addition, one or more CH2 groups in these radicals may each be replaced, independently of one another, by —C≡C—, —CF2O—, —OCF2—, —CH═CH—,  —O—, —CO—O—, —O—CO— in such a way that O atoms are not linked directly to one another, and in which, in addition, one or more H atoms may be replaced by halogen, L1 and L2 each, independently of one another, denote F, Cl, CF3 or CHF2, and the use thereof for an active-matrix display, in particular based on the VA, PSA, PA-VA, PS-VA, PALC, IPS, PS-IPS, FFS or PS-FFS effect.

    摘要翻译： 包含至少一种式I化合物的液晶介质，其中R1和R1各自彼此独立地表示具有1至15个C原子的烷基或烷氧基，此外还有一个或多个CH 2 这些基团中的基团可各自独立地被-C≡C-，-CF2O-，-OCF2-，-CH = CH - ， - O - ， - CO-O-，-O-CO- 以这样的方式使O原子彼此不直接连接，并且另外，一个或多个H原子可以被卤素所取代，各自彼此独立地表示F，Cl，CF 3或 CHF2，以及其用于有源矩阵显示的用途，特别是基于VA，PSA，PA-VA，PS-VA，PALC，IPS，PS-IPS，FFS或PS-FFS效应。
