摘要： A dry etching method performing dry etching of a material containing zinc forms and patterns a resist on the material to be etched, and etches the material using an etching gas which is a mixed gas of methane gas and an inert gas. A dry etching method that dry etches a material containing zinc etches the material using an etching gas that consists only of methane gas, an inert gas, and hydrogen gas alone. Another dry etching method that dry etches a material containing zinc introduces an etching gas that contains methane gas, an inert gas, and hydrogen gas into a dry etching device, in which the flow rate of the hydrogen gas is set such that it is equal to or greater than the value at which the amount of dissociated hydrogen becomes saturated, and etches the material using the etching gas. An EL element manufacturing method forms a first luminescent material containing zinc in its composition on a first insulated layer, forms a first resist that has a first pattern on the first luminescent material, dry etches the first luminescent material through the first resist, thereby forming the first luminescent layer; forms a second luminescent material having zinc in its composition on the first luminescent layer, forms a second resist on the second luminescent material, and dry etches the second luminescent material through the second resist.

摘要： A transparent thin-film EL display apparatus has a transparent thin-film EL element formed on a glass substrate. A rear substrate consisting of photochromic glass and the glass substrate on which the EL element is formed are disposed facing each other with the EL element located in between. A light-transmitting insulation material is inserted in a space between the two substrates and hermetically sealed. When the display on the EL element becomes hard to see due to light entering from the rear of the display apparatus, the photochromic glass reacts in response to the light and darkens the rear of the EL element, thereby blocking the light. Accordingly, normally the display apparatus displays various items of information through the front substrate and ensures visibility of the background through the display apparatus, and when high-intensity external light enters through the rear, the display apparatus reacts and blocks this light by means of a light shutter function, thereby enabling reliable display of the information without impairment of display contrast, thus guaranteeing a stable and highly reliable display.

摘要： A thin-film electroluminescence element is formed by laminating, in order, on a glass substrate which is an insulating substrate, a first transparent electrode including optically transparent ZnO, a first insulating layer including optically transparent strontium titanate, a luminescent layer including CaGa.sub.2.9 S.sub.4.2 to which Ce is added as a luminescent center, a second insulating layer including optically transparent strontium titanate and a second transparent electrode including optically transparent ZnO. The optical spectrum of the luminescent layer deviates towards a short wavelength side due to the crystal structure changing and the ligand field surrounding the Ce changing slightly due to the existence of excess Ga in the luminescent layer. Also, because calcium thiogallate is used, high light intensity can be maintained.

摘要： A thin-film EL display device of red luminescent color having high luminous intensity and high reliability is disclosed. The thin-film EL display device has a first transparent electrode, a first transparent insulating layer, a light-emitting layer of zinc sulfide (ZnS) with the addition of manganese (Mn), a red-light transmitting filter of amorphous silicon (a-Si), a second transparent insulating layer, and a second transparent electrode (second electrode), which are successively deposited one on top of another on a glass substrate. The EL display device produces red light from orange light emission from the light-emitting layer. High temperature resistance of the filter permits the insertion of the filter to a desired position during the fabrication process for the thin-film EL display device. Furthermore, since the filter characteristics of the thin-film EL display do not suffer degradation by the heat generated during the light emitting operation thereof, there is no concern for luminescent color deterioration with time.

摘要： A transparent display panel such as an electroluminescent panel is overlapped on a part of a conventional instrument panel for use in an automobile. The overlapped display panel displays additional information such as navigation maps when required and is turned off under a normal driving condition. When the overlapped transparent display panel is turned off, the conventional instrument panel displays information such as a vehicle speed, an engine speed and so forth. In this situation, overall luminance on the combined display panel is made uniform throughout a whole surface including the area where the transparent display panel is overlapped. To realize the uniformity of luminance, brightness of back lamps for illuminating the instrument panel is adjusted or a filter having an adequate transparency is used. The combined display panel may be also made by combining a non-transparent display panel with a conventional instrument panel. A filter may be used in this case to attain an overall uniform luminance on the combined display panel.

摘要： An electroluminescent element includes a glass substrate, on which are formed a first electrode, a first insulating layer, a first luminescent layer, a second luminescent layer, a second insulating layer, a second electrode, a protective film and a red color filter. In this structure, the first luminescent layer is made of ZnS having Mn added thereto, and the second luminescent layer is made of ZnS having Tb added thereto. Here, the clamp electric field intensity of the second luminescent layer is higher than that of the first luminescent layer, and the product of a dielectric constant and clamp electric field intensity of the first luminescent layer is larger than the product of a dielectric constant and clamp electric field intensity of the second luminescent layer. Consequently, it is possible to increase the luminance of light emitted from the luminescent layer and decrease the luminescence threshold voltage when the luminescent layer is made into a stacked layer structure.
