A black light display device is provided which utilizes a black light source in combination with fluorescent/phosphorescent display elements which can be thread, strings, monofilaments, disks or sculptured material. The display elements are formed about a spindle which is secure by fixed in a housing which houses the black light source and the fluorescent/phosphorescent elements. One form of housing comprises selectively removable transparent barrier which is transparent to the visible light radiating from the fluorescent display elements but opaque to the ultraviolet light radiating from the black light illumination source.
