| titleOfInvention | Liquid crystal alignment agent, liquid crystal alignment film, and liquid crystal display element |
| abstract | A liquid crystal alignment film having excellent printability and voltage holding ratio and having a stable pretilt angle is provided. A liquid crystal aligning agent includes (A) polyamic acid obtained by reacting 1,2,3,4-cyclobutanetetracarboxylic dianhydride and diamine, and (B) tetracarboxylic dianhydride and the following formula: Containing a polyimide formed by dehydrating and ring-closing a polyamic acid obtained by reaction with a diamine containing a specific mono-substituted phenylenediamine represented by (A) Number of amic acid structures possessed by polyamic acid (B) The ratio of the number of (B) imide ring structures to the total number of imide ring structures and the number of amic acid structures is 10 to 50%. [Selection figure] None |
