Method of manufacturing electromagnetic-wave shielding plate, electromagnetic-wave shielding plate manufactured thereby, and filter display using the same
To provide an electromagnetic-wave shielding plate superior in an electromagnetic-wave shielding property, a light-transmitting property and non-visibility of a mesh pattern at low cost. A pattern of a resin layer is printed on a metal layer of a transparent substrate by a printing method. After that, the metal layer is over-etched with the resin layer used as an etching mask, and a part of the resin layer protruding from the remaining metal layer in a plate-surface direction is removed. As a result, an electromagnetic-wave shielding plate superior in an electromagnetic-wave shielding property and non-visibility and having, for example, a pattern line width of 3 μm or more and 25 μm or less.
