Lichtempfindliches Material zum Orientieren einer Flüssigkristallvorrichtung und unter Verwendung davon hergestellte Flüssigkristallvorrichtung

摘要

Photosensitive orientation material providing unidirectional LC alignment to generate a high pretilt angle for various LC compounds, and superior thermal stability, and being suitable for mass production, especially for active matrix LC displays, include polysiloxanes, containing cinnamole groups. The compounds are preferably of formulae, where A is ```or ```Z is OH or Me ```p is 10 - 100 ```l is 1 - 10 ```m is 0 or 1 ```n is 0 or 1 and X, X 1 , X 2 and Y are H, F, Cl, CN, CF 3 , OCF 3 alkenyl or alkoxy.
