Abstract
An anti-reflection molding has a transparent substrate and an anti-reflection layer provided at least on a surface of the transparent substrate, an interface of a transparent window on which the anti-reflection layer is formed has an average surface roughness Ra of between 2.0 and 150 nm, and the molding has a curved surface having a radius of curvature of not less than 40 mm and protruding on a surface side, or a flat surface, in the transparent window.
Claims31
A method of manufacturing anti-reflection molding, comprising:
- placing a decorating sheet having at least a hard-coat layer formed on a substrate sheet to come a substrate sheet side thereof into contact with a cavity surface of a mold that is a curved surface having a radius of curvature of not less than 40 mm or a flat surface in an area corresponding to a transparent window;
- injecting transparent molten resin into the mold to obtain an integrated body of the decorating sheet and of a transparent substrate composed of the resin;
- subsequently peeling the substrate sheet from the integrated body to form a curved surface having a radius of curvature of not less than 40 mm and protruding on a surface side thereof or a flat surface that has an average surface roughness Ra of between 2.0 and 150 nm in the transparent window;
- and
- subsequently forming an anti-reflection layer on a surface side of the transparent substrate.
