Liquid crystal alignment agent, and liquid crystal alignment film and liquid crystal display element formed from the liquid crystal alignment agent

摘要

A liquid crystal alignment agent includes a polymer composition obtained by subjecting a diamine component and a tetracarboxylic dianhydride component to a reaction, a solvent, and a hydroxyl compound. Preferably, the hydroxyl compound has a weight average molecular weight ranging from 300 to 1,000,000. A liquid crystal alignment film formed from the liquid crystal alignment agent and a liquid crystal display element including the liquid crystal alignment film are also disclosed.
