    摘要： A reflection type display device (10) includes: a plasmon resonance layer (32) in which metal nanoparticles (80) are dispersed; a band-pass filter (40); a light shutter (20); and a silicon solar cell layer (50a) being provided close to the plasmon resonance layer (32). The band-pass filter (40) and the light shutter (20) are provided so as to overlap the plasmon resonance layer (32) in planar view. The reflection type display device (10) performs display in such a manner that: the metal nanoparticles (80) allow light having a specific wavelength to pass through; the light is then reflected by the band-pass filter (40); and the light shutter (20) adjusts an intensity of the light thus reflected.
