液晶取向剂、包含该液晶取向剂的液晶取向膜和液晶显示器
摘要：
本发明提供了液晶取向剂、包括该液晶取向剂的液晶取向膜和LCD。所述液晶取向剂包括通过将如下化学式1的化合物和如下化学式2的化合物聚合得到的聚硅氧烷聚合物以及溶剂：化学式1是Si(R1)4，化学式2是(R3)3Si-(R2)n-Si(R3)3，其中R1至R3如说明书所定义。液晶取向剂具有大LCDTV所需的很多优点，例如长期可靠性、高电压保持率(VHR)、稳定的预倾角保持力，杰出的液晶取向性和化学抗性等，因此其可以为LCD提供较高显示质量。此外，由于缺陷印刷而需要再加工时，可以容易地通过溶剂除去该液晶取向剂。
摘要（英）：

The present invention provides a liquid crystal oriented agent, a liquid crystal oriented film and LCD including the liquid crystal oriented agent. The liquid crystal oriented agent includes polyorganosiloxane polymer polymerized from a compound as formula 1 and a compound as formula 2, and solvent thereof; formula 1: Si(R1)4, formula 2: (R3)3Si-(R2)n-Si(R3)3, wherein the R1 to the R3 are defined as description. The liquid crystal oriented agent has advantages desired by large LCD TV, such as long-time reliability, high-voltage holding rate, stable pre-slant holding force, excellent liquid crystal orient ability and chemo resistance, thereby providing high display quality for LCD. Further, the liquid crystal oriented agent may be easily removed with solvent when re-processing is needed because of print defect.
