Mesogenic media comprising one or more compounds of formulae I or II preferably mesogenic media showing a blue phase, preferably stabilized by a polymer, and their use in electro-optical light modulation elements and their respective use in displays, as well as such devices.

Liquid crystal medium and liquid display

The instant invention relates to mesogenic media comprising one or more compounds of formula D wherein the parameters are as specified in the text, preferably to mesogenic media showing a blue phase, preferably stabilised by a polymer, and their use in electro-optical light modulation elements and their respective use in displays, as well as to such devices.

Liquid crystal medium and liquid crystal display

The instant invention relates to mesogenic media exhibiting a blue phase, comprising one or both components selected from the two following components, components A and B, component A, comprising one or more compounds selected from the group of compounds of formula I-M, and component B, consisting of one or more compounds selected from the group of compounds of formula I-U, wherein the parameters are as specified in the text, preferably stabilized by a polymer, and their use in electro-optical light modulation elements and their respective use in displays, as well as to such displays.

The present invention relates to polymerisable compounds, to processes and intermediates for the preparation thereof, and to the use thereof for optical, electro-optical and electronic purposes, in particular in liquid-crystal (LC) media and LC displays, especially in LC displays of the PS (polymer-stabilised) and PSA (polymer-sustained alignment) type.

Liquid-crystal display

The instant invention relates to mesogenic media exhibiting a blue phase, comprising one, two or more compounds of formula I-A wherein the parameters are as specified in the text, preferably stabilised by a polymer, and their use in electro-optical light modulation elements and their respective use in displays, as well as to such displays.

The present invention relates to polymerizable compounds, to processes and intermediates for the preparation thereof, and to the use thereof for optical, electro-optical and electronic purposes, in particular in liquid-crystal (LC) media and LC displays, especially in LC displays of the PS (polymer-stabilized) and PSA (polymer-sustained alignment) type.
