| titleOfInvention | Liquid crystal alignment agent, liquid crystal alignment film, and liquid crystal display element |
| abstract | Liquid crystal aligning agent containing the following specific polymer (A) and specific polymer (B). Specific polymer (A): tetracarboxylic dianhydride component containing bicyclo [3,3,0] octane-2,4,6,8-tetracarboxylic dianhydride and 4,4'-diaminodiphenylamine Polyamic acid obtained by reacting a diamine component containing at least one of diamine compounds represented by 3,6-diaminocarbazole. Specific polymer (B): A polyimide precursor having a structural unit represented by the following formula (7). (In the formula (7), R represents a hydrogen atom or an alkyl group, Y represents a tetravalent organic group, X represents a divalent organic group, and 10 to 100 mol% of X represents the formula (8). (It is a divalent organic group or paraphenylene group having any one of (10) in the structure.) (In the formula (8), m 1 is 2 to 18. integer.) (In Formula (9), one or more arbitrary hydrogen atoms on the benzene ring may be substituted with a monovalent organic group other than a primary amino group, and m 2 is an integer of 1 to 8. is there.) (In Formula (10), one or more of the arbitrary hydrogen atoms on the benzene ring may be substituted with a monovalent organic group other than the primary amino group, and m 3 is an integer of 1 to 4. is there.) |
