Abstract
Provided are an electromagnetic shielding film capable of improving brightness, a plasma display panel (PDP) filter using the electromagnetic shielding film, a PDP device including the electromagnetic shielding film, and a method of manufacturing the electromagnetic shielding film. The electromagnetic shielding film includes a transparent substrate, an electromagnetic shielding film pattern which is formed on the transparent substrate and whose face opposite to the transparent substrate is blackened, and a black conductive layer pattern which is formed on the electromagnetic shielding film pattern. The method includes (a) forming a non-conductive layer on a conductive substrate, (b) forming a non-conductive layer pattern by patterning the non-conductive layer, (c) forming a black conductive layer pattern on the conductive substrate exposed by the non-conductive layer pattern, (d) forming an electromagnetic shielding film pattern on the black conductive layer pattern, (e) oxidizing the electromagnetic shielding film pattern to blacken the same, and (f) separating the black conductive layer pattern and the electromagnetic shielding film pattern from the conductive substrate using a transparent substrate on a face of which an adhesive is formed.
