Abstract

PURPOSE:To enhance the illumination effect and decorative effect by improving the structure of reflecting plate and coloring the light source. CONSTITUTION:A reflecting plate beneath the display device is composed of a semitransparent irregular reflection layer 1 made of foamed moldings such as polyurethane, polystyrene and polyethylene and plastic sheets or the like to which are evaporated high reflectance metals such as Al and Ag, a photo conductive layer 2 made of acrylate or polyester material having a groove 4 provided entirely or partially, and a reflection layer 3 made of high reflectance metals such as Al and Ag and plastic or synthetic paper. And a light source lamp 5 is colored by fitting a cap 6 made of colored transparent plastic material. By thus setting up, usually, the appearance is the color of semitransparent irregular reflection layer 1, while in nighttime or dusk, when the lamp 5 is illuminated, the appearance becomes the color of the cap 6 and the illumination is equalized by the groove 4.
