| 摘要 |
The present invention relates to a label for identifying a genuine article using a plurality of nanostructures and a three-dimensional lens, the label comprising: an identification mark forming part including a three-dimensional lens layer that includes a lenticular lens having a plurality of semi-cylindrical convex lens arranged in parallel or a microlens having a plurality of semicircular convex lenses sequentially arranged, a focal distance layer disposed under the three-dimensional lens layer, and an image-forming layer disposed under the focal distance layer; and a coupling member for coupling the identification mark forming part to an article, wherein the image-forming layer includes an assembly in which a plurality of nanostructures protruding at heights and intervals of 50 to 200 nanometers is periodically and regularly arranged, and a medium having a refractive index different from the refractive indices of the nanostructures and the focal distance layer is disposed between the nanostructures and the focal distance layer. |
