| titleOfInvention | Composition for liquid crystal alignment film, liquid crystal alignment film, liquid crystal holding substrate and liquid crystal display device |
| abstract | (57) [Summary] [Structure] (a) General formula (I) (Wherein R 1 and R 2 are methyl groups, etc., R 3 and R 4 are monovalent hydrocarbon groups, etc.), and a diamine compound having a divalent aromatic group; Amine component (A) containing a diamine compound having two amino groups and at least one methyl group, (d) pyromellitic acid, etc. and (e) 3,3 ′, 4,4′-benzophenonetetracarboxylic acid diamine A composition for a liquid crystal alignment film containing a polyimide resin precursor obtained by reacting with an acid component (B) containing an anhydride, a liquid crystal alignment film using the same, a liquid crystal sandwich substrate and a liquid crystal display device. [Effect] It is possible to arbitrarily adjust the pretilt angle in accordance with the design of the liquid crystal display element without using a means such as using an additive to reduce the stability of the polyimide resin precursor solution.
