| titleOfInvention |
Tetracarboxylic acid-containing tetracarboxylic dianhydride, polymer, liquid crystal alignment agent, liquid crystal alignment film, and liquid crystal display element |
| abstract |
The present invention provides a liquid crystal alignment agent which can form a liquid crystal alignment film which is less likely to cause peeling or reduction. A tetracarboxylic dianhydride represented by the formula (1):nIn the formula (1), X is a divalent organic group containing at least one triazole ring; and R1 and R2 are each independently one selected from the group consisting of the following trivalent groups;n□ At least one hydrogen of these groups may also be substituted by methyl, ethyl or phenyl. |
