  • Patent number: 8426749
    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 0.1 Sa?Sb?5.0 Sa, in which Sa is the area of the intersection of the conductive portion and Sb is the area of the moire preventing part.
