Abstract
A laminated structure includes a base layer, a color layer and a reflective layer. The color layer is formed by a metalloid material, has a thickness and is superposed on the base layer. The reflective layer is superposed with the base layer and the color layer. Visible light passes through the thickness of the color layer and is reflected by the reflective layer to present a color. The wave length and color of visible light can be changed by controlling a thickness of the color layer.
