A polymerizable compound having absorption in the long UV wavelength range, a liquid-crystal (LC) medium comprising the polymerizable compound, and the use of the compound or LC medium for optical, electro-optical and electronic purposes, in particular in LC displays, especially in LC displays of the PSA (polymer sustained alignment) or SA (self-aligning) mode, an LC display of the PSA or SA mode comprising the compound or LC medium, and a process of manufacturing the LC display.

Liquid-crystal medium comprising polymerizable compounds

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 invention relates to a compound of formula I, wherein R, R, A, A, Z, X, X, Y, Y, Sp, Sp, o and p have one of the meanings as given in claim. The invention further relates to method of production of a compound of formula I, to the use of said compounds in LC media and to LC media comprising one or more compounds of formula I. Further, the invention relates to a method of production of such LC media, to the use of such media in LC devices, and to LC device comprising a LC medium according to the present invention. The present invention further relates to a process for the fabrication such liquid crystal display and to the use of the liquid crystal mixtures according to the invention for the fabrication of such liquid crystal display.

Liquid crystal mixture and liquid crystal display

Polymerizable compounds, processes and intermediates for their preparation, compositions containing them, polymers made from the compounds or compositions, and uses of the polymerizable compounds, compositions and polymers.

Polymerizable compounds

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.
