PROBLEM TO BE SOLVED: To provide a display which has a large screen, is light, and thin and has high-grade picture quality, and its manufacturing method. SOLUTION: The display is equipped with an ultraviolet emitter 3 which has a fine particle sintered substance where fine particles including the fine crystals of a semiconductor are joined together by sintered regions and emits an ultraviolet ray 400 nm in wavelength, a phosphor 6 which absorbs the ultraviolet ray emitted from the ultraviolet ray emitter 3 and emits a visible ray, a first electrode 4 and a second electrode 5 which are electrically connected to the ultraviolet emitter 3, and a controller which controls the voltage applied to the first electrode 4 and the second electrode 5. The ultraviolet phosphor 3 is used as an exciting energy source for the phosphor 6. When a current is injected into the ultraviolet emitter 3 through the first electrode 4 and the second electrode 5 by the controller, an ultraviolet ray is emitted from the ultraviolet ray emitter 3. This ultraviolet ray is absorbed in the phosphor 6, and a visible ray is emitted from the phosphor 6. Hereby, a image is displayed on the screen of the display. |
