  • Patent number: 6897921
    Abstract: A reflecting member having roughness is formed on a surface above a substrate and transferred onto a film with an adhesive layer interposed therebetween. For example, a removable organic insulating layer having roughness on a surface thereof is formed above a glass substrate, and then a metal layer is formed on the rough surface of the organic insulating layer, thus forming a reflecting member. The reflecting member is then transferred onto the film with and adhesive layer interposed therebetween.
