Liquid crystal materials, which possess unique optical properties, have received attention for security technology. Moreover, nonuniformity or randomness has attracted much attention from a security perspective. Since optical textures in liquid crystals usually have nonuniformity, we have proposed an application of UV-curable nematic liquid crystal films with nonuniform optical textures to security devices. These devices are embedded in the artificial products requiring authenticity and the information read form each film should be unique. So, these nonuniform patterns of optical textures can be used as the identification information.
