Abstract:
An electro-optical liquid-crystal display comprising:a re-alignment layer for re-aligning the liquid crystals, further comprising a field comprising a component; a liquid-crystal layer for the re-alignment wherein the component is parallel to the liquid-crystal layer; the liquid-crystal layer comprising a liquid-crystalline medium of positive dielectric anisotropy having a birefringence &Dgr;n of no more than about 0.12, comprising at least one compound of the formula I and at least one compound of the formula II or III â€ƒin which R1, R2 and R3 are each, independent of one another, alkyl or alkoxy having 1 to 7 carbon atoms or alkenyl, alkenyloxy or alkoxyalkyl having 2 to 7 carbon atoms, Y21 is H or F, Y11, Y12, Y22, Y31 and Y32 are each, independent of one another, H or F, â€ƒare each, independent of one another, â€ƒand Qâ€”X is F, Cl, â€”OCF2H or â€”OCF3, at least one compound of the formula Va: â€ƒwherein at least one of the groups R51 and R52 is alkenyl and the other is alkyl or alkoxy having 1-7 carbon atoms or alkenyl, alkenyloxy or alkoxyalkyl having 2-7 carbon atoms; at least one compound of the formula Vc â€ƒwherein R52 is n-alkyl having 1-5 carbon atoms and R51 is 1E-alkenyl having 2-5 carbon atoms.
