Patent ID: 7186447

Claim:
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 3 , —OCF 3 , or —OCHF 2 , and the rings A 1 and A 2 are each, independently of one another, 1,4-phenylene, 2- or 3-fluoro-1,4-phenylene, 2,3-difluoro-1,4-phenylene, trans-1,4-cyclohexylene or 1,4-cyclohexenylene, and 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 1 and R 2 are each, independently of one another, n-alkyl, ω-fluoroalkyl or n-alkenyl having up to 9 carbon atoms, the rings A 3 and A 4 are each, independently of one another, 1,4-phenylene, 2- or 3 fluoro-1,4-phenylene, trans-1,4-cyclohexylene or 1,4-cyclohexenylene, and Z 1 is —CH 2 CH 2 — or a single bond, and 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.
