The phosphor used therefor is an inorganic ion or oxide, and is not transparent when added to a resin and must be used in a cloudy state. Therefore, the ultraviolet light used as the excitation light cannot be displayed brightly unless it is irradiated from the front surface, but the irradiation from the front surface has a high risk of damaging the eyes due to the reflected light. Therefore, there is a strong demand for a transparent resin screen that can be illuminated from the rear surface.
