Abstract
(EN)
Provided are: a liquid crystal alignment agent with which it is possible to obtain a liquid crystal alignment film in which relaxation of stored charges takes place quickly, while accumulation of charges is low; a liquid crystal alignment film; and a liquid crystal display element. This liquid crystal alignment agent comprises polymers (A) and (B). Polymer (A): A polymer that is obtained through a reaction between a tetracarboxylic acid derivative component and a diamine component that contains a diamine represented by formula (1) and a diamine represented by formula (2). Polymer (B): A polymer that is obtained through a reaction between a tetracarboxylic acid derivative component and a diamine component containing at least one type of diamine represented by formula (3). Here, Y2 represents a nitrogen atom bound to an aromatic group or a divalent organic group having a nitrogen-containing aromatic heterocyclic ring.

L'invention concerne : un agent d'alignement de cristaux liquides avec lequel il est possible d'obtenir un film d'alignement de cristaux liquides dans lequel la relaxation des charges stockées se produit rapidement, tandis que l'accumulation de charges est faible ; un film d'alignement de cristaux liquides ; et un élément d'affichage à cristaux liquides. Cet agent d'alignement de cristaux liquides comprend des polymères (A) et (B). Polymère (A) : Un polymère qui est obtenu par une réaction entre un composant dérivé d'acide tétracarboxylique et un composant diamine qui contient une diamine représentée par la formule (1) et une diamine représentée par la formule (2). Polymère (B) : Un polymère qui est obtenu par une réaction entre un composant dérivé d'acide tétracarboxylique et un composant diamine contenant au moins un type de diamine représenté par la formule (3). Ici, Y2 représente un atome d'azote lié à un groupe aromatique ou un groupe organique divalent ayant un cycle hétérocyclique aromatique contenant de l'azote.
