| 摘要 |
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) 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). |
