Abstract
A reflective display device includes a bi-stable display, a front light module and a plurality of light converging films. The front light module is configured to provide a light to the bi-stable display, and the bi-stable display reflects the light. The light converging films are configured to converge the light reflected by the bi-stable display. The refractive index of the light converging film that is closest to the bi-stable display is lower than the refractive index of the light converging film that is farthest from the bi-stable display.
