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 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.

摘要： A second display panel having a lower luminance is combined with a first display panel having a higher luminance, forming a combined display panel. The entire surface of the combined display panel is covered with a dimming filter for ornamental purpose. Transparency of the dimming filter is enhanced in a wave-length region of the light emitted from the second panel to alleviate a brightness imbalance between the first and second panels. The transparency is enhanced also in another wave-length region corresponding to light complementary to the light emitted from the second panel, so that a color shift of the display of the first panel is avoided. Preferably, an electroluminescent display panel which emits light having a sharp peak in a specific wave-length region is used as the second panel.
