LIGHT-TRANSMITTING ELECTROMAGNETIC WAVE SHIELDING FILM AND MANUFACTURING METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a method of manufacturing a metal silver part used for an electromagnetic wave shielding material having both high electromagnetic shielding property and high transparency concurrently with remarkably reduced degradation of PDP image quality in terms of moire.

SOLUTION: The method of manufacturing a metal silver part includes exposing a silver salt-containing layer containing a silver halide as an optical sensor disposed on a substrate and carrying out a developing treatment thereby forming a light transmissive part and a mesh metal silver part, in which the width of a line constituting the mesh is 3 to 18μm, and an intersection growing rate in intersections of the lines constituting the mesh is >1 and≤1.5.
