The invention relates to a liquid-crystalline medium, preferably having a nematic phase and negative dielectric anisotropy, which comprises
a) one or more compounds of formula I
and
b) one or more compounds selected from the group of compounds of the formulae II and III
in which the parameters have the respective meanings indicated in claim 1, to the use thereof in an electro-optical display, particularly in an active-matrix display based on the VA, ECB, PALC, IPS or FFS effect, to displays of this type which contain a liquid-crystalline medium of this type, and to the use of the compounds of formula I for reduction of the dispersion of the birefringence of a liquid-crystalline medium which comprises one or more compounds of the formulae II and/or III.
本发明涉及一种液晶介质,最好具有向列相和负介电各向异性,它包括
a) 一种或多种式 I 化合物
和
b) 一种或多种选自式 II 和 III 化合物组的化合物
其中各参数的含义如权利要求 1 所示,用于电子光学显示器,特别是基于 VA、ECB、PALC、IPS 或 FFS 效应的有源矩阵显示器,用于包含此类液晶介质的显示器,以及用于减少包含一种或多种式 II 和/或 III 化合物的液晶介质的双折射分散的式 I 化合物。
