Abstract
A reflective display device includes a first absorption layer configured to be modulated between being strongly and weakly absorbing of light within a first specified wavelength band and to absorb light weakly in a second specified wavelength band and a third specified wavelength band, a second absorption layer configured to be modulated between being strongly and weakly absorbing of light within the second specified wavelength band and to absorb light weakly within the third specified wavelength band, a third absorption layer configured to be modulated between being strongly and weakly absorbing of light within at least the third specified wavelength band, and at least one reflector arranged between two of the first, second, and third absorption layers, the at least one reflector being configured to reflect light strongly within one of the specified wavelength bands assigned to the absorption layers above the at least one reflector.
