Electromagnetic shielding film

Abstract

An electromagnetic shielding film comprises a conductive portion and an opening portion, and a moire preventing part is formed in the opening portion. The moire preventing part may be formed approximately at the center of the opening portion, and may be formed on a line connecting intersections facing each other in the conductive portion in the mesh pattern. The moire preventing part may have a substantially circular planar shape or a polygonal planar shape (such as a quadrangular, pentagonal, hexagonal, or octagonal shape). Of course the moire preventing part may have an at least partially curved planar shape. The electromagnetic shielding film preferably satisfies the inequality 0.1Sa≦Sb≦5.0Sa, in which Sa is the area of the intersection of the conductive portion and Sb is the area of the moire preventing part.
