Electromagnetic shielding film for display device, filter having the same, and method of fabricating the same

Abstract

An electromagnetic shielding film for a display device includes a transparent, resinous first base, an intaglio pattern formed on at least one side of the first base, and an electromagnetic shielding pattern containing a conductive material with which the intaglio pattern is filled. A method of fabricating an electromagnetic shielding film for a display device, includes the steps of coating a first curable resin on one surface of a transparent backing, forming an intaglio pattern on the first curable resin using a patterning roll and curing the first curable resin, filling the intaglio pattern with a second curable resin containing a conductive material, and curing the second curable resin.

Problems solved by technology

[0012] The main problem with the etch method is that the exposure and etch process is expensive to process, and the material is also expensive since 90% or more of the copper is removed by etching

Due to these problems, a combined printing and plating type method was developed, but there is also a problem in that since the printed wiring is difficult to be as accurate as the etching method, the wiring width becomes large, which deteriorates visibility and increases defects Proportion

[0014] Further, transparent conductive films have a problem in that they are not as good at blocking electromagnetic waves as compared with metal mesh films.
