摘要: Described are matrix liquid crystal displays having two plane parallel support plates which together with a frame form a cell, integrated non-linear elements for switching individual picture elements on the support plates and a nematic liquid crystal mixture which is present in the cell and has a positive dielectric anisotropy and high resistivity. The liquid crystal mixture has a nematic phase range of at least 60° C., a maximum viscosity at 20° C. of 30 mPa·s and a mean dielectricity constant ε≦8. The liquid crystal mixture contains: a) at least 10% by weight of a liquid-crystalline component B having one or more compounds of the following formulae: and b) up to 90% by weight of a liquid-crystalline component A having one or more compounds with a dielectric anisotropy of −1.5 to 1.5 of the formula I:
