Abstract
A reflective display device (2) comprises a plurality of controllable light absorption layers (8) arranged in a stack. Each of the layers (8) is capable of absorbing incident light in a specified wavelength band. A selective reflector (10) is immediately behind at least one of the layers (8) and is adapted to reflect at least some wavelengths of light within the wavelength band and substantially to transmit light of other wavelengths.
