| abstract |
The invention relates to a liquid-crystalline medium based on a mixture of polar compounds having negative dielectric anisotropy, which contains at least one compound of formula I and at least one compound of formula I*, wherein R1, R2, R1* and R2* are each independently alkyl or alkoxy with 1 to 8 C atoms, where one or more CH2-groups in these radicals can be replaced by -CH=CH-, and are each independently but at least one of the rings A, B and C is L1-4 are each independently Cl, F, CF3 or CHF2, preferably L1-4 are each F, and s is 0 or 1, and their use in an electro-optical display. |
