A nematic liquid crystal for modulating light in electrooptical devices comprises: A. A 5-substituted-2-(4-substituted-phenyl)-pyrimidine of the formula <IMAGE> or a homolog thereof, R1 and R2 being the same or different and being selected from the group consisting of CnH2n+1-, CnH2n+1O-, CnH2n+1COO- or CnH2n+1CO- and n=1 to 12; B. A 4-substituted-cyclohexanecarboxylic acid-(4-substituted-phenylester) of the formula <IMAGE> or a homolog thereof, R being -CmH2m+1, -OCmH2m+1, -COCmH2m+1, -CN or -NO2, and n, m=1-10, and C. A 4-substituted-benzoic acid-(4-cyanophenylester) of the formula <IMAGE> or a homolog thereof, R being CnH2n+1- or CnH2n+1O- and n=1 to 14. |
