To provide a quick-response reflective display device that has increased display brightness and contrast and that achieves high display quality. In a reflective display device 1 of the present invention, a plurality of stages 20 are disposed on a substrate 10 so that the angles thereof with the substrate 10 are variable, a hologram element (reflective element) for transmitting light incident from a specific direction and reflecting light having a specific wavelength incident from a specific direction is formed on a surface of each of the stages 20 opposite from the substrate 10, an optical absorber 40 for absorbing 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 30R to 30B are disposed so as to reflect light components having different wavelengths.
