| abstract |
The present invention relates to dielectrically positive liquid-crystalline media comprising one or more compounds of the formula I n nin which the parameters have the meaning indicated in the specification, and optionally one or more compounds selected from the group of the compounds of the formulae II and IIIn n nin which the parameters have the meaning indicated in the specification, and optionally one or more compounds of the formula IVn n nin which the parameters have the meaning indicated in the specification, and to liquid-crystal displays containing these media, especially to active-matrix displays and in particular to TN, IPS and FFS displays. |
