Document Type and Number:
WIPO Patent Application WO/2020/184629
Kind Code:
A1
Abstract:
Provided is a liquid crystal display element that maintains a high voltage holding ratio while accumulating little charge and for which bright spots can be minimized even when friction physically occurs, such as rubbing by a spacer. The liquid crystal alignment agent is characterized by containing component (A) and component (B). Component (A): a polymer (A) having at least one type of repeating unit selected from the group consisting of the repeating unit represented by formula (1) and the repeating unit represented by formula (2). Component (B): a compound (B) of 2,000 or less in molecular weight, having within the molecule the partial structure represented by formula (b), and provided with a basic moiety containing a nitrogen atom. The definitions of the symbols in the formulae are as described in the specification.
