Abstract: The present invention relates to a liquid-crystalline medium (LC medium), to the use thereof for electro-optical purposes, and to LC displays containing this medium.

Abstract: The invention relates to polyfluorinated additives for use as components in liquid-crystal mixtures, to liquid-crystal mixtures which comprise these compounds, and to liquid-crystal displays based on these mixtures.

Abstract: The invention relates to dielectrically positive liquid crystalline media comprising a compound of formula I wherein the parameters have the meaning given in claim 1 and to liquid crystal displays comprising these media, especially to active matrix displays and in particular to TN and IPS mode displays.

Abstract: The present invention relates to a liquid-crystalline medium (LC medium) which is distinguished by the fact that it comprises one or more compounds of the formula 1 and one or more compounds of the formula 2 and one or more compounds selected from formulae 3, 4 and 5, in which the individual radicals have the meanings according to Claim 1, and to the use thereof for electro-optical purposes and to LC displays containing this medium.

Abstract: The invention relates to a liquid-crystalline medium which comprises at least one compound of the formula I, in which R1 and R1* each, independently of one another, denote an alkyl or alkoxy radical having 1 to 15 C atoms, where, in addition, one or more CH2 groups in these radicals may each be replaced, independently of one another, by in such a way that O atoms are not linked directly to one another, and in which, in addition, one or more H atoms may be replaced by halogen, A1 denotes L1 denotes F, Cl, CF3, OCF3 or CHF2, and to the use thereof for electro-optical purposes, in particular for shutter glasses, 3D applications, in TN, PS-TN, STN, TN-TFT, OCB, IPS, PS-IPS, FFS, PS-FFS and PS-VA-IPS displays.

Abstract: The invention relates to compounds of the formula I and to a liquid-crystalline medium which comprises one or more compounds of the formula I, in which R1, X1, X, Y1 and Y2 have the meanings indicated in Claim 1, and to the use thereof for electro-optical purposes, in particular for shutter glasses, 3D applications, in TN, PS-TN, STN, TN-TFT, OCB, IPS, PS-IPS, FFS, PS-FFS and PS-VA-IPS displays.

Abstract: The invention relates to a liquid-crystalline medium comprising at least one compound of the formula I, in which R1 has the meanings indicated in Claim 1, and to the use thereof in liquid-crystalline media and in electro-optical liquid-crystal displays.
