ABSTRACT:
The invention provides a quick-response reflective display device that has increased display brightness and contrast and that achieves high display quality. In a reflective display device of the present invention, a plurality of stages are disposed on a substrate so that the angles thereof with the substrate are variable, a hologram element (reflective element) to transmit light incident from a specific direction and reflect light having a specific wavelength incident from a specific direction is formed on a surface of each of the stages opposite from the substrate, an optical absorber to absorb light passing through each hologram element is formed on a side of the hologram element opposite from the light incident side, and a plurality of hologram elements are disposed so as to reflect light components having different wavelengths.
