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

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 the use of hydrophilic compounds of the formula I as photopolymerisation initiators of polymerisable substance mixtures which comprise unsaturated compounds, or for the photochemical crosslinking of linear polymers, in which the parameters have the meaning indicated in Claim, to sealants for liquid-crystal displays which comprise the hydrophilic photoinitiators, to novel hydrophilic photoinitiators of the formula I, and to the liquid-crystal displays produced using these sealants.

Benzil monoketals and the use thereof

The present invention relates to a method of reducing ODF mura in liquid crystal (LC) displays of the polymer sustained alignment (PSA) type and to PSA LC displays made by this method.
