Patent attributes
An electromagnetic wave shielding material 1 comprises a light-shielding electrical conductor layer 11 having, on its observer-side external surface, a blackening layer 12. The electrical conductor layer 11 comprises a mesh portion 2 that has a large number of openings adjoining one another and faces the center portion 5b of the image-luminescent part 5a of a display device 5, and a frame portion 3 that surrounds the mesh portion 2 and faces the outer edge portion 5c of the image-luminescent part 5a of the display device 5. When trimming the screen of a display D with a black-colored light-shielding layer, since the electromagnetic wave shielding material 1 is used, it is not necessary to perform9 an additional printing step or the like, so that the total number of steps and material cost are not increased. Moreover, such electromagnetic wave shielding material does not cause non-uniformity in light-shielding properties compared with a light-shielding layer formed by printing. The frame portion 3 includes a light-transmitting pattern part 9 having patterned openings 4a.
