Claims

[Claims for Utility Model Registration] (1) The substrate of an internally illuminated display device exhibits a white color under visible light or a normal color that does not emit fluorescence;
and a fluorescent portion that emits fluorescence under ultraviolet light to form characters or designs, and if necessary, ultraviolet light is irradiated onto this substrate to cause only the fluorescent portion to emit light. Expression display device. (2) On the substrate of the internally illuminated display device, it exhibits a white color under visible light or a normal color that does not emit fluorescence;
In addition, characters or designs are formed using two or more types of fluorescent portions that emit different fluorescent colors under ultraviolet light, and if necessary, ultraviolet light is irradiated onto this substrate to cause only the fluorescent portions to emit light. An internally illuminated display device according to claim 1. (3) On the substrate of an internally illuminated display device, there is a non-fluorescent part that does not emit fluorescence under ultraviolet light, and a non-fluorescent part that is white under visible light or a normal color that does not emit fluorescence and is different under ultraviolet light. A claim characterized in that characters or designs are formed by combining two or more types of fluorescent portions that emit fluorescent colors, and ultraviolet light is irradiated onto the substrate as necessary to cause only the fluorescent portions to emit light. 1
The internally illuminated display device described. (4) A rotating cover having an opening in a part is provided around the light emitting part of the ultraviolet lamp, and the display board is partially irradiated by rotating the rotating cover. The internally illuminated display device according to any one of the above. (5) Using an ultraviolet lamp equipped with a rotating cover with an opening partially around the light-emitting part and a white lamp equipped with a rotating cover with an opening partially around the light-emitting part, each rotating cover is used. 4. The internally illuminated display device according to claim 1, wherein the display panel is irradiated by differentially rotating the display panel. (6) The substrate is formed of a black substrate that is transparent to light, and by irradiating ultraviolet light from the inside to the outside of this substrate, only the fluorescent portion is displayed so as to stand out from the black substrate. An internally illuminated display device according to any one of claims 1 to 5.
