PROBLEM TO BE SOLVED: To develop a liquid crystal aligning agent to obtain a liquid crystal aligned film excellent in liquid crystal aligning properties and a black level.SOLUTION: A liquid crystal aligned film is made of polyamic acids and derivatives thereof obtained by reacting tetracarboxylic dianhydrides with diamines represented by at least general formula (I). (In the formula, R represents an amide group whose nitrogen atom is bonded via a methylene group to a hydroxyl group at the end.) |
