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

Polymerizable compounds and the use thereof in liquid-crystal displays

The present invention relates to dielectrically positive liquid-crystalline media comprising one or more compounds of the formula I in which the parameters have the meaning indicated in the specification, and optionally one or more compounds selected from the group of the compounds of the formulae II and III in which the parameters have the meaning indicated in the specification, and optionally one or more compounds of the formula IV in which the parameters have the meaning indicated in the specification, and to liquid-crystal displays containing these media, especially to active-matrix displays and in particular to TN, IPS and FFS displays.

Liquid-crystalline medium and liquid-crystal display

The invention relates to a liquid-crystalline medium having negative dielectric anisotropy based on a mixture of polar compounds, which comprises at least one compound of the formula I in whichRand Rhave the meanings indicated in claimin amounts of &#x2267;30% by weight, based on the medium,and to the use thereof for an active-matrix display based on the ECB, PALC, FFS or IPS effect.

Liquid-crystalline medium

The present invention relates to dielectrically positive liquid-crystalline media comprising a dielectrically positive component, component A, comprising a dielectrically positive compound of the formula (I), in which the parameters have the meaning indicated in the specification, and optionally a second dielectrically positive component, component B, comprising one or more dielectrically positive compounds having a dielectric anisotropy of greater than 3 and optionally a dielectrically neutral component, component C, and to liquid-crystal displays, especially to active-matrix displays and in particular to TN, IPS, FFS and OCB displays, containing these media.
