Liquid crystal (LC) alignment agent, LC alignment film and LC display device having thereof |
摘要 |
A liquid crystal (LC) alignment agent is disclosed, which comprises polymer (A), tertiary hydramine (B) and epoxy group-containing compound (C). The LC alignment agent is added with a tertiary hydramine (B) and has an epoxy value of 0.065 to 0.900. The LC alignment agent can be employed to form a LC alignment film for enhancing the resulted LC alignment film with better rubbing resistance. A LC display (LCD) device that uses the LC alignment film has better voltage holding ratio (VHR) and process stability.
