摘要： A reflector comprises a substrate provided with a plurality of projecting and depressed structures which are groups of columnar portions each serving as a basic unit and composed of a plurality of minute columnar portions, which are separate from each other or at least partially connected to each other, and with a light reflecting thin film provided over the projecting and depressed structures. This allows incident light to be scattered and reflected in a forward direction or the like, not in the regular reflection direction, and provides a reflector having a superior contrast property and a superior paper-white property, a fabrication method therefor, and a reflective display device comprising the reflector. The reflective display device has a liquid crystal layer provided between a pair of substrates. One of the pair of substrates is provided with projecting and depressed portions covered with a metal film and with a support portion for supporting the counter substrate, which are molded integrally. The arrangement reduces reflection in the regular reflection direction and enhances brightness and whiteness, while reducing the occurrence of uneven display by providing a uniform cell gap.
