摘要： An electroluminescent display panel which is able to selectively display different colors by changing a voltage level imposed thereon is made in a simple structure. A first luminescent layer (4) emitting green light, for example, and a second luminescent layer (5) emitting orange light, for example, are directly laminated on each other without interposing an intermediate electrode therebetween. The second luminescent layer covers only a part of the first luminescent layer to form a single layer portion and a double layer portion. The single layer portion emits green light at a low voltage level, while the double layer portion emits lemon light having a higher luminance at a high voltage level. The display may be made in a form of a matrix or a certain pattern. The display panel may be used as an instrument panel for an automobile. The green light display is used at night time, while the lemon light display with a high luminance is used at day time to cope with sun light.
摘要翻译：通过改变施加在其上的电压电平能够选择性地显示不同颜色的电致发光显示面板以简单的结构进行。例如，发射绿光的第一发光层（4）和例如发射橙色光的第二发光层（5）彼此直接层叠，而不在其间插入中间电极。第二发光层仅覆盖第一发光层的一部分，以形成单层部分和双层部分。单层部分以低电压水平发射绿光，而双层部分在高电压水平下发出具有较高亮度的柠檬光。显示器可以以矩阵或某种图案的形式制成。显示面板可以用作汽车的仪表板。绿灯显示屏在夜间使用，而白天采用高亮度的柠檬灯显示屏可以应付日光。

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： 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 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.
