Abstract: PROBLEM TO BE SOLVED: To obtain good display characteristics such as aligning property of liquid crystal molecules and afterimage characteristics without rubbing treatment by irradiating an org. thin film containing a soluble polyimide having an alicyclic structure on a substrate with ion beams. SOLUTION: The liquid crystal alignment film is produced by irradiating an org. thin film containing a soluble polyimide having an alicyclic structure formed on a substrate with ion beams. In the alignment treatment with ion beams, characteristics required for the alignment film are that the film is easily etched with ion beams and that the formed grooves are not deformed. The polyimide having an alicyclic structure satisfies the requirement above described. As the agent for the liquid crystal alignment film, two or more kinds of polymers may be mixed to be used. In this case, the soluble polyimide having an alicyclic structure or an imide structural unit having an alicyclic structure is preferably included at least by >=10 wt.% of the solid content in the agent.
