DIE AUSRICHTUNG VON FLÜSSIGKRISTALLEN INDUZIERENDE MATERIALIEN UND OPTISCHE FLÜSSIGKRISTALLELEMENTE

摘要

The present invention provides novel polyamic acids and polyimide optical alignment layers for inducing alignment of a liquid crystal medium. The novel compositions comprise crosslinking diamines containing a C3-C20 linear or branched hydrocarbon chains containing 1 to 4 carbon-carbon double bonds. The invention further describes liquid crystal displays comprising the novel polyimide optical alignment layers.
