印刷し、そのフィラメント材を中空に張るものである。[Prior Art] Conventionally, in order to use incandescent light emission for displays and the like, it is necessary to arrange fine incandescent filaments at high density. On the other hand, instead of the method of arranging coil filaments made by winding wire into a spiral, a method has been proposed that is more efficient in manufacturing and easier to produce with higher density. In this method, a groove is formed on a substrate, a filament material is screen printed so as to straddle the groove, and the filament material is stretched in the air.

This is the light-emitting section 4. A groove 2 is formed in the ceramic insulating substrate 1, and a filament material (
A thin film 3 (mainly tungsten) is formed. Known electrodes are attached to both ends of the filament material WI film 3, and when a voltage is applied between these electrodes, a current flows through the filament material thin film 3, causing it to glow and emit light. The display board is made up of an infinite number of light emitting sections 4 arranged vertically and horizontally, and displays figures and characters by selectively emitting light.
犬に上記発光部４の製造方法を以下に説明する。The method of manufacturing the light emitting section 4 for dogs will be explained below.

もので、主成分はタングステンである。Next, a paste-like filament material is attached to the plate-shaped ceramic insulating substrate 1 by screen printing. First of all, the above? After creating a screen having a transparent part slightly longer than the width of 1It2, the screen is positioned so that the transparent part straddles the groove 2. Then, the pasty filament material 3 is applied using the screen. This pasty filament material is a known material used for printed wiring, and its main component is tungsten.
この時、溝部も他の基板表面と同一面になっているため
、良好な印刷が可能である。At this time, since the groove portion is also flush with the surface of the other substrate, good printing is possible.
