Abstract
A method for partially treating a water-repellent glass sheet is disclosed which comprises irradiating part of a water-repellent glass film, formed on the water-repellent glass sheet, with a stream of plasma jets generated by a plasma jet irradiating gun. By such plasma jet irradiation, the film part can be removed easily even when the glass sheet has a curved surface.
