ABSTRACT:
A display device includes a display element which is arranged to have a plurality of electrode areas and to permit selective switchover between a transmitting state and a diffusing state by controlling an electric field, and a light emitting source which is arranged in such a position as to make an illumination color thereof visually confirmable only in an electrode area of the display element which is made into the diffusing state. The device is arranged such that displays can be provided adequately with a single light emitting source even when it is necessary to use a plurality of display parts for providing displays independently of each other.
