ABSTRACT:
A method for forming a face film on a face panel includes the steps of applying electromagnetic wave-shielding solution on the face panel, calcining the face panel, and photoreducing the precursor metal ion contained in the electromagnetic wave-shielding film by radiating ultraviolet ray on the face panel for about 20-50 minutes. The precursor is selected from silver or gold. Preferably, the step of calcining is conducted at a temperature of about 160.degree.-200.degree. C. Further preferably, the ultraviolet ray is in the range of 1-50 mW/cm.sup.2.
