[0500] These mixtures, mixtures A-1 to A-12, have good dielectric ratios (ε.sub.⊥/Δε), good ratios of (γ.sub.1/k.sub.11) and are characterized by very good transmissions in an FFS display and show very short response time. Moreover, they show excellent deep temperature stability at least up to a temperature of −20° C.
