ABSTRACT:
An electromagnetic wave shielding material1comprises a light-shielding electrical conductor layer11having, on its observer-side external surface, a blackening layer12. The electrical conductor layer11comprises a mesh portion2that has a large number of openings adjoining one another and faces the center portion5bof the image-luminescent part5aof a display device5, and a frame portion3that surrounds the mesh portion2and faces the outer edge portion5cof the image-luminescent part5aof the display device5. When trimming the screen of a display D with a black-colored light-shielding layer, since the electromagnetic wave shielding material1is used, it is not necessary to perform9an 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 portion3includes a light-transmitting pattern part9having patterned openings4a.
