| titleOfInvention | Liquid crystal phase |
| abstract | A liquid crystal phase consisting of at least three components A, B and C, each of which contains one or more compounds, wherein component A has a viscosity of at most about 25 mPa.s at 20°, a clearing point of at most 130° and a dielectric anisotropy between about -2 and about +2, component B has a dielectric anisotropy above about +8, component C has a clearing point of more than 130° and a dielectric anisotropy between about -2 and about +2, characterized in that component A contains at least one compound of formula (III), in which R1 is alkyl of 1 to 12 C atoms, in which in addition one or two non-adjacent CH2 groups can be replaced by O atoms, -CO-, -O-CO-, -CO-O- and/or -CH=CH- groups, R2 has one of the meanings of R1, A3 is (alpha) or (beta), Z1 is -CO-O-, -O-CO- or -CH2CH2-, o is 1 or, if A3 is (gamma), also 2, Cy is trans-1,4-cyclohexylene, and Phe is 1,4-phenylene, has suitable material properties for use in supertwisted nematic cells. |
