— Optical filters with a high shielding capability against electromagnetic (EM) radiation for plasma‐display panels (PDPs) have been studied. We developed optical filters with high conductivity by utilizing a copper‐mesh layer, which was processed by using roll‐to‐roll photolithography and roll‐to‐roll etching. The copper‐mesh layer has a cross‐striped pattern with a surface resistance of 0.05Ω/□ and an opening ratio of approximately 93%. In combination with the copper‐mesh layer, organic dyes were applied to reduce the PDPs unfavorable emissions, such as near‐infrared light, and to control the transmission properties to improve the PDPs picture quality.
