METHOD FOR FORMING PATTERNS USING LASER ETCHING

The present invention relates to a method for manufacturing the fine pattern of a conductive metal wire transparent electrode having superior index matching properties using various laser powers. More particularly, the method for manufacturing the fine pattern of a conductive metal wire transparent electrode includes: (1) forming a uniform conductive metal nanowire on various base materials; (2) forming various polymer layers, which are optically transparent and have insulating properties, on the conductive transparent electrode; and (3) directly irradiating the surface of a conductive film with a laser in order to form a fine pattern electrode. Thus, the method for manufacturing a conductive pattern electrode includes: uniformly arranging metal nanowires to form a conductive layer having low resistance; and forming a protection film using an insulating polymer on the conductive electrode layer to protect the conductive electrode layer. Also, when such technology for forming the conductive fine pattern electrode is used, the laser power may be varied in order to address the chronic visibility problems of the transparent electrode and to achieve superior pattern resolution and fine line width.
