ABSTRACT:
A display device which comprises a case in which a light source is accommodated, color changing means by which the color of light from the light source is changed to a predetermined color of illumination, a display panel that is formed of a light-transmitting material to cover the front opening of the case and which is provided with a light-shielding film in areas other than those corresponding to a display portion, and color display controller that is disposed on the display panel and which controls the color of illuminating light that issues from the light source and is transmitted through the display portion. The color display controller is composed of a plurality of thin strips that have a color different from that of illumination provided by the color changing means and which are spaced from each other. The light source is disposed behind the strips, with the color provided by the color changing means being displayed when the light issuing from the light source has passed between the strips, while a composite of the color provided by the color changing means and the color of the strips is displayed when the light issuing from the light source has been reflected from the strips.
