An electro-optical liquid crystal display with active-matrix addressing, in which the liquid-crystal layer has a homeotropic or tilted homeotropic alignment in the switched-off state and which contains a liquid-crystalline medium of negative dielectric anisotropy. The medium contains A) 30-70% by weight of two or more compounds of the formula I and B) 20-50% by weight of two or more compounds of the formula II in which R1, R2, and m are as defined in claim 1. The displays are particularly capable of operation based on the vertically-aligned cholesteric or nematic (VAC or VAN) effect. |
