PHOTOSENSITIVE POLYIMIDES FOR OPTICAL ALIGNMENT OF LIQUID CRYSTALS |
摘要 |
<p>The present invention provides novel polyamic acids and polyimide optical alignment layers for inducing alignment of a liquid crystal medium. The novel compositions comprise reactive diamines containing a C<SUB>3</SUB>-C<SUB>20 </SUB>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.</p> |
