The present invention relates to a liquid crystal aligning agent which contains a polymer that has a site having an isocyanate group and/or a blocked isocyanate group, a site having a photoreactive group having photoalignment, and a site having at least one functional group selected from an amino group and a hydroxyl group in each molecule. The present invention provides a liquid crystal display element which enables baking at low temperatures during the formation of a liquid crystal alignment film by a photoalignment method, the liquid crystal alignment film being able to be imparted with alignment regulating property and pretilt angle developing property.
本发明涉及一种液晶配向剂,该液晶配向剂含有一种聚合物,该聚合物在每个分子中具有具有
异氰酸酯基团和/或封端
异氰酸酯基团的位点、具有光配位的光活性基团的位点以及具有至少一个选自
氨基和羟基的官能团的位点。本发明提供了一种液晶显示元件,在通过光配位法形成液晶配位膜的过程中,可在低温下进行烘烤,该液晶配位膜能够被赋予配位调节特性和前倾角度显影特性。
