Document Type and Number:
WIPO Patent Application WO/2019/044339
Kind Code:
A1
Abstract:
[Problem] To provide an electrode film that is excellent in mesh pattern invisibility and image visibility, and a method for manufacturing the same. [Solution] A method for manufacturing an electrode film comprising: a step for sequentially stacking a metal layer and a black photoresist layer on a first principal surface of a transparent substrate; a step for partially exposing, developing, and patterning in a mesh shape the black photoresist layer; a step for processing the metal layer into a metal mesh electrode by, using the patterned black photoresist layer as an etching mask, etching the metal layer until the width thereof becomes smaller than the width of thin lines constituting a mesh of the black photoresist layer; and a step for softening the black photoresist layer by heating, and thereby covering not only the upper surface but also both side surfaces of each of thin lines constituting a mesh of the metal mesh electrode with a flap of the softened black photoresist layer.
