Abstract: Provided is a coloring pattern structure. The coloring pattern structure includes: a substrate; a light-transmitting dielectric layer formed on at least one surface of the substrate; and a composite material layer disposed on an upper surface of the light-transmitting dielectric layer and formed of a metal and a first material not having a thermodynamic solid solubility in the metal, wherein the metal included in the composite material layer has a pattern coated only on portions of the upper surface of the light-transmitting dielectric layer, and the first material is coated on the remaining area where the metal is not coated.
