ABSTRACT:
This invention relates to a novel Color Display Device constructed in the shape of a flat box. The top and bottom covers of such box have each electrode on each inner face thereof. At least one of the pair of electrodes is transparent, and also at least one of the pair has a dielectric layer on its inner face. A certain solution containing dye, is filled in the space between the pair of electrodes, and when a voltage is impressed across these electrodes, a change occurs in the light absorption of the dye solution, causing a change in the tint or the saturation of color to said solution visible under a visual light, and thus resulting in a color display.
