In FEM liquid crystal display elements), organic polymer films such as polyimide, polyimide-isoindoquinalicindione, and polyimide-benzimidazopyrrolon have been proposed as materials for the alignment film. Although such conventional polymer films have uniform liquid crystal orientation and excellent heat resistance and insulation resistance, they cannot be said to sufficiently suppress the generation of induced domains, and the film itself does not adhere well to the glass substrate. It had the disadvantage of being inferior in quality.
