Liquid-crystal phase

A liquid-crystal phase, characterised in that it contains at least one component of the formula I in which R is alkyl having 1 to 12 carbon atoms, R is alkyl, alkoxy or alkanoyloxy, in each case having 1-12 carbon atoms, Cy is trans-1,4-cyclohexylene, and Ph is 1,4-phenylene, at least one component...

Zusammenfassung:A liquid-crystal phase, characterised in that it contains at least one component of the formula I in which R is alkyl having 1 to 12 carbon atoms, R is alkyl, alkoxy or alkanoyloxy, in each case having 1-12 carbon atoms, Cy is trans-1,4-cyclohexylene, and Ph is 1,4-phenylene, at least one component of the formula II in which R and R are each alkyl having 1 to 12 carbon atoms, Cy is trans-1,4-cyclohexylene, A is trans-1,4-cyclohexylene, trans-1,3-dioxane-2,5-diyl or a single bond, and each Phe is 1,4-phenylene which is unsubstituted or substituted by fluorine, at least one component of the formula III in which R is alkyl having 1 to 12 carbon atoms, R is alkyl or alkoxy, in each case having 1 to 12 carbon atoms, m is 0 or 1, Pyr is pyrimidine-2,5-diyl, and Cy and Phe are as defined above, and at least one component of the formula IV in which R is alkyl having 1 to 12 carbon atoms, Dio is trans-1,3-dioxane-2,5-diyl, and Phe is as defined above, has particularly good multiplex properties.
