(26) Above and below, the symbols and abbreviations have the following meanings: V.sub.o threshold voltage, capacitive [V] at 20 C. n the optical anisotropy measured at 20 C. and 589 nm the dielectric anisotropy at 20 C. and 1 kHz cl.p. clearing point [ C.] K.sub.1 elastic constant, splay deformation at 20 C. [pN] K.sub.3 elastic constant, bend deformation at 20 C. [pN] .sub.1 rotational viscosity measured at 20 C. [mPa.Math.s], determined by the rotation method in a magnetic field LTS low-temperature stability (nematic phase), determined in test cells.

(27) The display used for measurement of the threshold voltage has two plane-parallel outer plates at a separation of 20 m and electrode layers with alignment layers comprising SE-1211 (Nissan Chemicals) on top on the insides of the outer plates, which effect a homeotropic alignment of the liquid crystals.

(28) All concentrations in this application, unless explicitly indicated otherwise, relate to the corresponding mixture or mixture component. All physical properties are determined in accordance with Merck Liquid Crystals, Physical Properties of Liquid Crystals, status November 1997, Merck KGaA, Germany, and apply to a temperature of 20 C., unless explicitly indicated otherwise.
