Abstract
A method of manufacturing a pigment. The method includes: providing a substrate; forming stacked multiple sets of films successively on the substrate, wherein each set of films comprises a sacrificial layer and an optical film, the sacrificial layer and the optical film are successively stacked, and the sacrificial layer is a stripping agent with compressive stress or low stress; and obtaining the pigment by stripping and crushing formed multiple sets of films.
