    • A liquid crystal aligning agent is provided to realize excellent adhesion at the edge portion of a substrate and printability, and uniform and stable vertical aligning capability, and to form a liquid crystal aligning film having excellent coating layer uniformity. A liquid crystal aligning agent comprises either or both of a polyamic acid represented by the following formula 1 and having a number average molecular weight of 10,000-500,000 g/mol and a polyimide polymer represented by the following formula 2 and obtained by imidizing the polyamic acid, and a solvent comprising 5-60 wt% of dipropylene glycol dimethyl ether or monoethylene glycol dimethylene ether based on the total weight of the solvent. In formula 1, R1 is a tetra-valent organic group derived from an alicyclic or aromatic acid dianhydride, and R2 is a divalent organic group derived from an aromatic diamine. In formula 2, R3 is a tetra-valent organic group derived from an alicyclic or aromatic acid dianhydride, and R4 is a divalent organic group of the formula 3 derived from an aromatic diamine.
    • 提供了一种液晶取向剂,以在基板的边缘部分和印刷性方面实现优异的粘附性,并且具有均匀和稳定的垂直取向能力,并且形成具有优异的涂层均匀性的液晶取向膜。 液晶取向剂包括由下式1表示的数均分子量为10,000-500,000g / mol的聚酰胺酸和由下式2表示的聚酰亚胺聚合物中的一种或两种,并通过酰亚胺化聚酰胺酸 以及基于溶剂总重量的包含5-60重量%二丙二醇二甲醚或单乙二醇二甲醚的溶剂。 在式1中,R 1是衍生自脂环族或芳族酸二酐的四价有机基团,R 2是衍生自芳族二胺的二价有机基团。 在式2中,R 3是衍生自脂环族或芳族酸二酐的四价有机基团,R 4是衍生自芳族二胺的式3的二价有机基团。
