A display panel such as a plasma display panel is provided in which an electromagnetic-wave shielding material is integrated whereby electromagnetic-wave shielding efficiency is imparted to a display panel itself. A transparent film 2 having a conductive pattern 3 is bonded to a front surface of a plasma display panel 20 by transparent adhesives 4A. The conductive pattern 3 is in a mesh form having a line width of 50 mum or less and an open area ratio of 75% or more and is formed by vapor plating or liquid phase plating. To form a conductive pattern, dots 12 are printed on a transparent film 11 by using material which is soluble in solvent such as water. Then, a conductive material layer 13 is formed so as to cover over all the dots 12 and exposed portions of the transparent film 11. The film 11 is cleaned by the solvent such as water. By the cleaning process, the soluble dots 12 are dissolved and the conductive material on the dots 13 are also removed from the film 11. Accordingly, conductive material formed on the exposed portions are left uncovered by the dots so as to form a conductive pattern 14. In this manner, the conductive pattern 14 plated on areas of the film 11 other than the dots 12 is formed.
