Abstract

Disclosed are a liquid crystal (LC) medium containing a polymerisable compound, a process for its preparation, its use for optical, electro-optical and electronic purposes, in particular in LC displays, especially in an LC display of the polymer sustained alignment (PSA) type, and to an LC display containing the LC medium, especially a PSA display.

Description

technical field [0001] The present invention relates to liquid crystal (LC) media comprising polymerizable compounds, to processes for their preparation, to their use for optical, electro-optical and electronic purposes, in particular in LC displays, especially in polymer stabilized alignment (PSA) Use in type LC displays, and to LC displays, especially PSA displays, comprising the liquid crystal medium. Background technique [0002] One mode of liquid crystal display (which has gained both widespread attention and commercial use) is the so-called PS ("polymer stabilized") or PSA ("polymer stabilized alignment") mode, for which the term "polymer stabilized" is also occasionally used. change". In PSA displays, one or more polymerizable compounds comprising an LC mixture (hereafter also referred to as "host mixture") and small amounts, typically <1% by weight such as 0.2-0.4% by weight, are used, preferably LC medium for polymerizable monomeric compounds. After filling t...
