<p>PROBLEM TO BE SOLVED: To provide an etching method for the transparent electrode of a touch screen using a laser. SOLUTION: This method has (a) a stage where the transparent electrode film is prepared on the touch screen made of a high polymer material, and (b) a stage where the transparent electrode film is etched by being irradiated with a laser beam of the ultraviolet range. Specific processing line width is secured during the irradiation with the laser beam, and the laser beam is put out of focus to prevent the touch screen from damaging. Consequently, the development of touch screen industry which is variously demanded as environment-friendly methods as compared with a conventional wet etching method and increase of its uses can be expected.</p> |
