本発明は螢光表示管あるいはプラズマディスプレイ等の
ガラス製真空外囲器を有する表示装置に関し、特に排気
管を用いることのない表示装置の製造方法に関する。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a display device having a glass vacuum envelope such as a fluorescent display tube or a plasma display, and in particular to manufacturing a display device without using an exhaust pipe. Regarding the method.
従来この種の真空表示装置は、あらかじめ電極等の組立

排気孔を通して蓋部材の低融点ガラスと真空外囲器との
わずかな間隙を介して真空に排気したりガス導入を行な
った後蓋部材の低融点ガラスを溶融して真空管を形成し
ていた。Conventionally, this type of vacuum display device has been constructed by forming a vacuum envelope by sealing a display glass and a substrate glass with electrodes etc. assembled in advance, and then using an exhaust gas provided in a part of the envelope. A vacuum tube is formed by evacuation or gas introduction through a small gap between the low-melting glass of the lid member and the vacuum envelope through the hole, and then melting the low-melting glass of the lid member.
従って上述した従来の真空表示装置は、蓋部材の低融点
ガラスと真空外囲器との間隙が狭いために、排気抵抗が
大きく管内で発生するガスを十分に排気するにはガス出
しに長時間を要し、生産効率を上げにくくまた高真空に
排気することが困難であった。Therefore, in the conventional vacuum display device described above, the gap between the low melting point glass of the lid member and the vacuum envelope is narrow, so the exhaust resistance is large and it takes a long time to exhaust the gas generated inside the tube. This made it difficult to increase production efficiency and to evacuate to a high vacuum.

ある。The present invention has been made in view of the above problems, and includes a step of forming a concave and/or convex portion in a part of the low melting point glass of the lid member, and a step of forming a concave portion and/or a convex portion in a part of the low melting point glass of the lid member, and after combining the vacuum envelope and the lid member. The present invention provides a method for manufacturing a vacuum display device without an exhaust pipe, which includes a step of charging the lid, and a step of melting and sealing the low-melting glass of the lid member while the button is evacuated.
次に、本発明について図面を参照して説明する。 Next, the present invention will be explained with reference to the drawings.

Reference numeral 2 represents an exhaust hole, and reference numeral 4 represents a lid member in which a portion of the low melting point glass 3 is provided with a concave and/or convex portion. The above-mentioned vacuum envelope 1 and lid member 4 are combined and put into a vacuum device, and the exhaust hole 2
The interior of the display device is evacuated through the gaps created by the concave and/or convex portions, and the filament is decomposed by being heated with electricity, and then the low melting point glass 3 of the lid member is further evacuated in the evacuated state. It was melted to complete a fluorescent display tube.
