An elevator display device has a light-emitting display unit, a resin cover, and a metallic tone film. The resin cover is disposed in front of the light-emitting display unit so as to cover the light-emitting display unit, and transmits light from the light-emitting display unit. The metallic tone film is disposed on the cover, and transmits the light from the light-emitting display unit. The metallic tone film is made of a nano-layered film that is optically designed to have a metallic sheen. |
