Abstract
An electromagnetic shielding sheet is capable of shielding electromagnetic radiation generated by a display, has a proper transparency and uniformly distributed meshes, prevents the occurrence of white and/or black spot defects and linear defects and glaring, and ensures the satisfactory visibility of images. The electromagnetic shielding sheet has a conductive structure () having lines () having straight parts of widths (W) in the range of C(1±30%), where C is a predetermined value. The radius (r) of curvature of a side surface (S) extending between the upper side (U) and the lower side (B) of a bank in a section of the lines () in a plane perpendicular to the transparent sheet meet a condition expressed by: 1.5t≦r≦3.0t, where t is the thickness of the conductive structure ().
