| 摘要 |
<p>The present invention provides novel polyamic acids and polyimide optical alignment layers (14) for inducing alignment of a liquid crystal medium (16). The novel compositions comprise crosslinking diamines containing 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 (14).</p> |
