Document Type and Number:
Japanese Patent JP6281567
Kind Code:
B2
Abstract:
Provided are: a liquid crystal alignment film with which adhesive properties between a sealant and the liquid crystal alignment film can be improved, the occurrence of display unevenness in the vicinity of a frame of a liquid crystal display element can be inhibited, even under high-temperature/high-humidity conditions, and a reduction in voltage retention rate can be inhibited; a liquid crystal display element; and a liquid crystal alignment agent. The liquid crystal alignment agent includes: an additive including an isocyanate group; an additive including an amino group and a hydroxyl group; and at least one polymer selected from the group consisting of polyimide precursors and polyimides obtained by causing a reaction between a diamine component and a tetracarboxylic acid component.
