Abstract:
1. A matrix liquid crystal display comprising: 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, wherein the liquid crystal mixture is based on the following components: a) at least 10% by weight of a liquid-crystalline component B comprising one or more compounds of the following formulae: wherein R is n-alkyl or n-alkenyl of up to 9 carbon atoms, X is —CF the rings A b) up to 90% by weight of a liquid-crystalline component A comprising one or more compounds having a dielectric anisotropy of −1.5 to 1.5 of the formula I wherein R the rings A Z the nematic 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.
