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

Polymerisable compounds and the use thereof in liquid-crystal displays

Compounds of the formula I, and a liquid-crystalline medium, preferably having a nematic phase and negative dielectric anisotropy, which comprises  in which the parameters have the respective meanings indicated in Claim. The use thereof in an electro-optical display, particularly in an active-matrix display based on the VA, ECB, PALC, FFS or IPS effect. Displays of this type which contain a liquid-crystalline medium of this type. Use of the compounds of the formula I for the stabilization of a liquid-crystalline medium which comprises one or more compounds of the formula II.

Liquid-crystalline medium, method for the stabilization thereof, and liquid-crystal display

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

Polymerizable compounds and the use thereof in liquid-crystal displays

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

The present invention relates to a liquid crystal (LC) medium comprising a polymerizable compound, to a process for its preparation, to its use for optical, electro-optical and electronic purposes, in particular in an LC display, especially in an LC display of the PSA ('polymer sustained alignment') type, and to an LC display comprising the LC medium.

Liquid crystal medium

The invention relates to compounds of the formula I, and to a liquid-crystalline medium, preferably having a nematic phase and negative dielectric anisotropy, which comprises  in which the parameters have the respective meanings indicated in Claim, to the use thereof in an electro-optical display, particularly in an active-matrix display based on the VA, ECB, PALC, FFS or IPS effect, to displays of this type which contain a liquid-crystalline medium of this type, and to the use of the compounds of the formula I for the stabilization of a liquid-crystalline medium which comprises one or more compounds of the formula III-O.
