Liquid-crystalline (LC) media having positive dielectric anisotropy and liquid-crystal displays (LCDs) containing these media, especially displays addressed by an active matrix and in particular energy efficient LC displays of the TN, PS-TN, STN, TN-TFT, OCB, IPS, PS-IPS, FFS, HB-FFS, XB-FFS, PS-FFS, SA-HB-FFS, SA-XB-FFS, polymer stabilised SA-HB-FFS, polymer stabilised SA-XB-FFS, positive VA or positive PS-VA type. The media have an improved long-term stability against UV radiation and elevated temperatures.

Liquid-crystalline medium

A liquid crystal medium having negative dielectric anisotropy and containing one or more compounds of formulae B and C and one or more compounds of formula G and the use thereof for an active-matrix display, in particular based on the VA, SA-VA, IPS, PS-IPS, FFS, PS-FFS, UB-FFS or PS-UB-FFS effect.

Liquid-crystal medium

A liquid-crystal (LC) medium based on a mixture of polar compounds, its use for optical, electro-optical and electronic purposes, in particular in LC displays, especially in LC displays of the vertically aligned mode, to an LC display of the vertically aligned mode containing the LC medium, especially an energy-saving LC display and a process of manufacturing the LC display.

A liquid-crystal (LC) material having negative dielectric anisotropy and the use thereof for optical, electro-optical and electronic purposes, such as for example in LC displays, in particular energy saving displays based on the ECB, IPS or FFS effect, where the liquid crystal medium contains one or more compounds of formula I and one or more compounds compounds of formulae IIA, IIB, IIC and IID

A liquid crystal medium containing a compound of formula I

Liquid crystal medium

A liquid-crystalline medium which comprises at least one compound selected from the group of compounds of the formulae IA to IH, in which

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.

A liquid-crystalline medium having least one compound of the formula I, and at least one compound of the formulae ST-1 to ST-17, in which Rand R*, Aand A*, Zand Z*, X, Land L, R, ring A, Z, p and q have the meanings indicated in claim, and the use thereof for an active-matrix display, in particular based on the VA, PSA, PA-VA, SS-VA, SA-VA, PS-VA, PALC, IPS, PS-IPS, UB-FFS, U-IPS, FFS or PS-FFS effect.

The invention relates to a liquid-crystalline medium and to the use thereof for an active-matrix display, in particular based on the VA, PSA, PS-VA, PM-VA, SS-VA, PALC, IPS, PS-IPS, FFS or PS-FFS effect.

The invention relates to a liquid-crystalline medium which comprises at least one compound of the formula I, wherein the radicals R, L, L, n and A are as defined herein, and to the use thereof for an active-matrix display, in particular based on the VA, PSA, PS-VA, PA-VA, PALC, FFS, PS-FFS, IPS or PS-IPS effect.

Liquid-crystalline media which can be used, in particular, for electro-optical displays having active-matrix addressing based on the ECB effect and for IPS (in-plane switching) displays or FFS (fringe field switching) displays.

Liquid-crystalline media

The invention relates to a liquid-crystalline medium, characterised in that it comprises one or more compounds of the formula IA, andone or more compounds of the formula IB, in which R, R, X, Xand Yhave the meanings indicated in Claim, 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.

Compounds of the formula I in which groups and parameters that occur have the definitions given in the disclosure. Preparation methods for these compounds. Uses of the compounds as components in liquid-crystalline media. Electrooptical display elements comprising the liquid-crystalline media.
