The present invention relates to a liquid-crystal (LC) medium comprising one or more polymerisable compounds and to the use of the LC medium for optical, electro-optical and electronic purposes, in particular in LC displays, especially in LC displays of the polymer sustained alignment (PS, PSA) or self-aligning (SA) type.

Liquid-crystal medium comprising polymerisable compounds and the use thereof in liquid-crystal displays

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 (PS, PSA) and self-aligning (SA) type.

Polymerisable compounds and the use thereof in liquid-crystal displays

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

Liquid-crystalline media (LC media) comprising self-aligning mesogens (self-alignment additives) which effect homeotropic (vertical) alignment of the LC media at a surface or the cell walls of a liquid-crystal display (LC display). The self-alignment additives contain five-ring systems. LC displays having homeotropic alignment of the liquid-crystalline medium (LC medium) without conventional alignment layers are provided.

Compounds for the homeotropic alignment of liquid-crystalline media

Liquid crystal (LC) media comprising polymerisable compounds as further specified in the description and claims and a self-alignment additive for vertical alignment. The media are adapted for use in LC displays, especially in LC displays of the polymer-sustained alignment type.

Liquid crystal media comprising polymerisable compounds

Compounds of the formula I, liquid-crystalline media which contain at least one compound of the formula I and electro-optical displays which contain the LC mixtures, especially for the self-aligning VA, PSA, PS-VA, PVA, MVA, PM-VA, HT-VA or VA-IPS mode in which R, R, ring A, Z, Z, Sp, P, L, L, r1, r2, r3, m, n, p1 and p2 have the meanings indicated above.

Liquid-crystalline medium

A liquid-crystalline media (LC media) containing a low-molecular-weight, non-polymer component, and a combination of self-alignment additives for vertical alignment of two or more of the specified kinds (formulae IA to IM). The combination of two or more self-alignment additives affect homeotropic (vertical) alignment of the LC media at a surface or the cell surfaces of a liquid-crystal display (LC display).

Liquid-crystalline media having homeotropic alignment

The invention relates to compounds of the formula I, in which R, A, Z, m, L, L, Land X have the meanings indicated in Claim, to a process for the preparation thereof, and to liquid-crystalline media comprising at least one compound of the formula I and to electro-optical displays containing a liquid-crystalline medium of this type.

Naphthalene compounds for liquid-crystalline mixtures

Polymerisable compounds and processes and intermediates for the preparation thereof. Also liquid-crystal (LC) media comprising the polymerisable compounds, and 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 PSA ('polymer sustained alignment') type.

Disclosed are liquid-crystalline media (LC media) comprising a low-molecular-weight component and a polymerisable component. The polymerisable component contains self-aligning, polymerisable meso-gens (polymerisable self-alignment additives) which effect homeotropic (vertical) alignment of the LC media at a surface or the cell walls of a liquid-crystal display (LC display). Disclosed are also LC displays having homeotropic alignment of the LC medium without alignment layers. Further disclosed are the structures for polymerisable self-alignment additives.

The invention relates to a liquid-crystalline medium which comprises at least one compound of the formula I,  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, 

Liquid-crystal medium

The invention relates to 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.

The present invention relates to a liquid crystal (LC) display of the FFS type comprising a liquid crystal medium with negative dielectric anisotropy and a di- or multireactive polymerizable compound, and an alignment layer inducing planar alignment in the LC medium.
