The contradiction between counterfeiting and forgery is deepening, and the development of counterfeiting technology with strong confidentiality, high security, and non-reproducibility has become an urgent need for social and economic development. In this context, liquid crystal anti-counterfeiting technology has become an area of great interest due to its excellent performance, high practicality, and wide market appreciation. However, the existing anti-counterfeiting technology is not rich enough in hierarchy, and the hidden graphic is only one color. Therefore, this study proposes a device structure with a dual information security layer consisting of a guest-host liquid crystal anti-counterfeiting film layer and a cholesteric liquid crystal anti-counterfeiting film layer, each layer containing different information content. Through different light patterns, different display contents can be obtained, thus achieving a multi-dimensional anti-counterfeiting effect. The design features polarization-related transmission-reflection differences and an asymmetric light response in the transmission direction compared to conventional single-layer guest-host liquid crystal anti-counterfeit film layers. The use of this easily prepared anti-counterfeit film layer overlay design not only improves the security level of the security code but also reduces the cost of application.
