A light valve that is operable in and electrically switchable between an optically clear and transparent state and an opaque state, wherein one or more polymerisable mesogenic compounds provided in a layer containing a liquid-crystalline medium that comprises one or more mesogenic compounds, one or more chiral compounds, one or more dichroic dyes and the one or more polymerisable mesogenic compounds are subjected to photopolymerisation. Further, a liquid-crystalline medium used in the method, a light valve obtained or respectively obtainable by carrying out the method, and the use of the light valve in mobile devices.

Liquid crystal-based light valve

The present invention relates to a liquid crystal (LC) medium comprising polymerisable compounds, to a process for its preparation, to its use for optical, electro-optical and electronic purposes, in particular in LC displays, and to LC displays comprising it.

Liquid crystal medium containing polymerisable compounds

Liquid-crystal medium

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 R, X, X, Yand 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.

Liquid-crystalline medium

The invention relates to a liquid-crystalline medium comprising one or more compounds of the formula I in whichR, ring A and Lhave the meanings indicated in Claimand to the use thereof in electro-optical liquid-crystal displays.

The present invention relates to dielectrically positive, preferably nematic, media comprising one or more polymerisable compounds, to polymer-stabilized media obtained therefrom, to the use thereof in liquid-crystal displays, and to these displays, in particular PSA-IPS, PSA-FFS and PSA-positive VA displays.
