    摘要： There is described a liquid crystalline mixture for electro-optical devices which are operated according to the two-frequency matrix addressing procedure. The mixture consists of three components A, B and C, each of which contains one or more compounds. Component A has a viscosity of at most about 40 cp, a clearing point of at least about 40.degree. C. and a dielectric anisotropy between about -2 and about +1. Component B has a dielectric anisotropy below about -2 both above and below the cross-over frequency of the total mixture and component C has a dielectric anisotropy above about +10, a clearing point of at least about 100.degree. C. and there is a cross-over frequency in the total mixture of at most about 15 kHz at 20.degree. C. Novel compounds for such mixtures and their manufacture and use are also described. The novel mixtures make possible especially high multiplex rates and short response times.
