A reflective display device includes a flexible pouch of ordered copolymer layers with a lamellar structure and a solvent, the flexible pouch having at least a first and second surface. A substrate is placed in operative contact with a first surface of the flexible pouch. Thereafter, one of a pressure or heat application mechanism is placed in operative connection with at least one of the first and second surfaces of the flexible pouch. A controller operatively associated with one of the pressure or heat application mechanisms, is used to selectively apply pressure and/or heat to the flexible pouch. The application of the heat or pressure at a specific location on the flexible pouch results in a change of reflectivity in the ordered copolymer layers, thereby altering the color at that location.
