Abstract

A method for ablating a coating film, cutting glass, and performing post-treatment by using a laser according to the present invention includes coating one side or both sides of thin mother glass with a coating solution for preventing chemical contact in order to proceed with selective chemical treatment, drying the coating solution to form a coating film on one side or both sides of the thin mother glass, obtaining thin-film glasses in cell units applied to electrical and electronic products from the thin mother glass, healing a laser-cut surface of the cut thin-film glasses in cell units through selective chemical treatment of the cut thin-film glasses in cell units, cleaning the thin-film glasses in cell units, and then ablating all of a coating film formed on a surface of the thin-film glasses in cell units, and cleaning the thin-film glasses in cell units from which all of the coating film has been ablated and then chemically healing the surface of the thin-film glasses in cell units in order to eliminate defects or flaws on the surface of the thin-film glasses in cell units from which all of the coating film has been ablated.
