Abstract
Provided is a deposition apparatus that has a metal evaporation source for depositing a reflective layer, a pigment evaporation source for depositing a coloring layer, and a plasma polymerization source (electrode) for depositing a protective layer disposed inside a single vacuum processing room. By carrying out a step of depositing the reflective layer, a step of depositing the coloring layer, and a step of depositing the protective layer in the common vacuum processing room, processes can be simplified and an operation time can be reduced.
