Abstract: Disclosed is a security film, including: a substrate layer, a nano-wire grid polarizer layer having a line grid pattern, and at least one information identification layer, wherein the substrate layer, the nano-wire grid polarizer layer and the information identification layer are stacked so that at least one information identification layer is provided in at least one position selected from among a position on an outer surface of the substrate layer, a position between the substrate layer and the nano-wire grid polarizer layer, and a position on an outer surface of the nano-wire grid polarizer layer. This invention can provide a high-dimensional information storage medium by combining a nano-wire grid polarization film, manufactured via a nano-imprinting process, with various security elements, making it possible to enhance security against illegal counterfeiting and copying.
