Document Type and Number:
WIPO Patent Application WO/2023/074391
Kind Code:
A1
Abstract:
The present invention provides a polymer composition that is suitable for a liquid crystal aligning agent which enables the achievement of a liquid crystal alignment film that has excellent resistance to an AC afterimage and a low pretilt angle. This polymer composition is characterized by containing the following (A) component and (B) component. (A) component: at least one polymer (A) which is selected from the group consisting of a polyimide precursor having a repeating unit represented by formula (a) and a polyimide that is an imidized product of the polyimide precursor. (B) component: a polyester (B) which has a repeating unit represented by formula (b1) but does not have the repeating unit represented by formula (a) and an imidized structure thereof. Formula (a) (The definition of each symbol is as described in the description.) Formula (b1) (The definition of each symbol is as described in the description.)
