In this Letter, the identification device disclosed in the present invention is comprised of: a carrier and a plurality of pseudo-pixels; wherein each of the plural pseudo-pixels is formed on the carrier and is further comprised of at least a light grating composed of a plurality of light grids. In a preferred aspect, each of the plural light grids is formed on the carrier while spacing from each other by an interval ranged between 50nm and 900nm. As the aforesaid identification device can present specific colors and patterns while it is being viewed by naked eye with respect to a specific viewing angle, the identification device is preferred for security and anti-counterfeit applications since the specific colors and patterns will become invisible when it is viewed while deviating from the specific viewing angle.
