摘要

PROBLEM TO BE SOLVED: To remove the gradation part of a functional film made from an organic compound or the functional film freely and easily by a dry process. SOLUTION: In the production of a substrate coated with the functional film having the gradation part in which the functions of a functional part in which the surface of the substrate is coated with the functional film made from the organic compound and the functional film are changed gradually, an area corresponding to the gradation part or a film removing part is subjected to corona discharge, exposure to plasma, or ultraviolet irradiation to form the gradation part or the film removing part.
