COMPOSITION, LIQUID CRYSTAL ALIGNINIG AGENT, LIQUID CRYSTAL ALIGHMENT FILM, AND LIQUID CRYSTAL DISPLAY ELEMENT

摘要

Provided are: a composition which has excellent coating film properties; and a liquid crystal alignment film which uses the composition and has high wettability and spreadability of a coating solution over a substrate and uniform coating film properties, while having excellent coating film properties in the edge. Specifically provided is a liquid crystal alignment film which has the above-mentioned excellent characteristics even in cases where the liquid crystal aligning agent uses a polyamide acid or solvent-soluble polyimide that is obtained using a diamine compound having a side chain. A composition which contains the component (A) and the component (B) described below. Component (A): A solvent which is represented by formula (1). (In formula (1), X1 represents an alkyl group having 1-3 carbon atoms.) Component (B): At least one polymer that is selected from the group consisting of polyimide precursors and polyimides obtained by imidizing the polyimide precursors.
