The present invention provides a liquid crystal aligning agent which provides a liquid crystal alignment film having surface anchoring force and pretilt angle development stability by an optical aligning method.
The liquid crystal aligning agent comprises a polymer having a photo-crosslinkable structure a structure having at least one group selected from the group consisting of a fluorine-containing organic group, an alkyl group having 10 to 30 carbon atoms and alicyclic organic group having 10 to 30 carbon atoms and optionally, (C) a thermally crosslinkable structure.
本发明提供了一种液晶定向剂,通过光学定向方法提供具有表面锚定力和预倾角稳定性的液晶定向膜。该液晶定向剂包括具有光交联结构的聚合物,结构中至少包含以下群组之一:含
氟有机基团、具有10至30个碳原子的烷基基团和具有10至30个碳原子的脂环族有机基团,以及可选的(C)热交联结构。
