ABSTRACT:
An illuminative display device for use in an electronic apparatus including a cabinet with a metallic color surface and having at least a main function and a subsidiary function. The display device comprises a light source and a transparent sheet spaced apart therefrom by a predetermined distance, wherein a colored layer composed of a thin film and being the same or substantially the same in color as the metallic color of the cabinet is formed on one side of the transparent sheet opposed to the light source, and a backing layer with cutout characters is formed on one side of the colored layer opposed to the light source, so as to display the characters relative to the subsidiary function. And other display characters relative to the main function are shown on the surface of the transparent sheet at positions not overlapping with the display characters relative to the subsidiary function. The display characters are completely invisible when the illuminating light is turned off, whereby the appearance of the display device is rendered congruous with the metallic or similar color of the surrounding cabinet.
