Document Type and Number:
WIPO Patent Application WO/2023/219112
Kind Code:
A1
Abstract:
Provided is a novel diamine which, when used as a starting material for a polymer that constitutes a liquid crystal alignment film, is capable of suppressing the reduction in the molecular weight of the polymer during baking and is capable of forming a liquid crystal alignment film having a high voltage retention rate. The diamine is represented by any of formulas (dA-1) through (dA-6).
