Abstract:
An electronic apparatus comprising:an apparatus case having an aperture portion; a module disposed in the apparatus case by corresponding to the aperture portion; an ultraviolet ray-emitting portion for emitting a first light in an ultraviolet range, the ultraviolet ray-emitting portion being disposed in the apparatus case by corresponding to a peripheral portion of the aperture portion; a luminescent layer for emitting a colored light by reacting to the first light in the ultraviolet range, the luminescent layer being provided on the module; and an ultraviolet ray-reflecting film for reflecting the first light in the ultraviolet range emitted from the ultraviolet ray-emitting portion and transmitting lights other than the first light in the ultraviolet range, the ultraviolet ray-reflecting film being provided on at least one of a front surface and a rear surface of the aperture portion, wherein the ultraviolet ray-emitting film has a structure for transmitting not less than 92% of a second light other than in the ultraviolet range with a wavelength not less than 450 nm, for reflecting 70% to 90% of the first light in the ultraviolet range from the ultraviolet ray-emitting portion, for cutting off not less than 90% of a light with a wavelength not more than 300 nm, and for cutting off around 98% of a fourth light with a wavelength not more than 400 nm, among lights in the ultraviolet range inputted through the aperture portion from an outside of the apparatus case.
