LIQUID CRYSTAL ALIGNMENT AGENT, LIQUID CRYSTAL ALIGNMENT FILM, AND LIQUID CRYSTAL DISPLAY ELEMENT

摘要

Provided are a liquid crystal alignment agent whereby a liquid crystal alignment film can be formed that is highly resistant to rubbing, as well as a liquid crystal alignment film that uses the liquid crystal alignment agent, and a liquid crystal display element. The liquid crystal alignment agent is prepared by combining at least one polymer selected from a polyimide precursor and a polyimide obtained by imidization of a polyimide precursor, and a compound having a blocked isocyanate group. A liquid crystal alignment film is formed using the liquid crystal alignment agent. A liquid crystal display element is manufactured using the liquid crystal alignment film.
