Abstract: 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.

Abstract: PROBLEM TO BE SOLVED: To easily make an image display device lightweight and thin and to attain high picture quality by arranging ultraviolet luminescent elements and phosphors absorbing ultraviolet light and emitting visible light in sequence on a transparent substrate, and utilizing the ultraviolet luminescent elements as an excitation energy source for the phosphors. SOLUTION: Multiple first electrodes 3 arranged nearly in parallel to each other, an ultraviolet luminescent film 4, multiple second electrodes 5 arranged nearly in parallel to each other and nearly perpendicularly to the first electrodes 3, and phosphors 6 are laminated in this order on a transparent substrate 2. The first electrode 3 and the ultraviolet luminescent film 4 form an ultraviolet luminous EL element 7. The controller of this image display device controls the electric field applied between the first electrodes 3 and the second electrodes 5. When the electric field is applied between the first electrodes 3 and the second electrodes 5, the ultraviolet luminous EL elements 7 emit ultraviolet light with the wavelength 400 nm or below. The phosphors 6 wavelength-convert the ultraviolet light into visible light and emit it in the incidence direction of the ultraviolet light.

Abstract: PROBLEM TO BE SOLVED: To enable optimum sound image setting with rear speakers and meet the movements of the listener's head. SOLUTION: A sound signal outputted from a speaker behind a listener is corrected according to a head sound transfer function and then a sound image is localized at a specified position in a specified direction, e.g. in the space in front of the listening position. Further, an optimum head sound transfer function is selected for correction while the position relation between the speaker and the head of the listener is detected. COPYRIGHT: (C)2004,JPO

Abstract: PROBLEM TO BE SOLVED: To stably radiate electromagnetic waves having a wavelength of 400 nm or shorter with stable luminance for a long time. SOLUTION: This element is provided with an ultraviolet emission film 4 formed from a nitride of a group 3B element, and a pair of conductive films 3, 5 formed on both the surface of the ultraviolet emission film 4 in a form interposing it. The ultraviolet emission film 4 radiates an electromagnetic wave having a wavelength 400 nm or shorter by applying electric field to the pair of conductive films 3, 5. Since the nitride of a group 3B element used for the ultraviolet emission film as a base material is a chemically stable compound, the element is not deteriorated by the moisture or carbon dioxide in the atmosphere, even under a strong electric field or exposure to an ultraviolet-ray and can hence maintain stable luminance over a long time.
