METHOD FOR PRODUCING TRANSPARENT CONDUCTING FILM
Abstract:
Provided is a transparent conducting film having a favorable optical property, favorable electrical property, and almost no in-plane resistance anisotropy. A method for producing a transparent conducting film provided with a conducting layer containing a metal nanowire and a binder resin, comprises steps of: preparing a coating liquid containing the metal nanowire and the binder resin, and coating the coating liquid on one main face of a transparent substrate, wherein, in the coating step, a bar-coat printing method is performed using a bar provided with a groove having a pitch (P) and a depth (H) which satisfy a ratio P/H of 5 to 30.
