titleOfInvention | Liquid crystal alignment agent, liquid crystal alignment film, and liquid crystal display element |
abstract | A polyimide precursor obtained by reacting a tetracarboxylic acid component containing a tetracarboxylic dianhydride represented by the following formula [1] and an aliphatic tetracarboxylic dianhydride represented by the following formula [2] with a diamine component, and the same A liquid crystal aligning agent containing at least 1 type of polymer selected from polyimides obtained by imidizing a polyimide precursor. (In formula [2], Z 1 is at least one tetravalent group selected from the following formulas [2a] to [2j].) (In formula [2a], Z 2 to Z 5 represent a hydrogen atom, a methyl group, a chlorine atom, or a benzene ring, and may be the same or different, respectively, and in formula [2g], Z 6 and Z 7 are hydrogen atoms or methyl groups. And may be the same or different, respectively.) |
