接着される。このようにして表示装置の容器として裏容
器１と裏容器とが準備できる。As the material for the container, commonly used glass is used, which has almost the same coefficient of expansion as the metal plate 2.4 of this embodiment made of 42-6 alloy. Powdered glass 7 is applied between the back container 1 made of glass in advance and the metal plate 2 from which the inside has been removed by etching a 42-6 alloy plate, and fired at about 450''C in an electric furnace or the like. As a result, the container 1 and the metal plate 2 are bonded together.Similarly,
a metal plate 4, a glass frame 3, and a terminal 6 made of 42-6 alloy;
By firing the glass back plate 5 through the powdered glass 7, the metal plate 4, the glass frame 3, the terminals 6, and the back plate 5 are bonded together. In this way, the back container 1 and the back container can be prepared as containers for the display device.
次に、前記裏容器の中に電極構体１２を配置した後、裏
容器１を配置し、金属板２，４の周辺部に冷却用のエア
ー１０とレーザ１１を照射して、溶接を縁に沿って行な

定する。このレーザ溶接装置は、炭酸ガスレーザ装置或
はＹＡＧレーザ装置等の何れでもよい。Next, after placing the electrode assembly 12 in the back container, the back container 1 is placed, and cooling air 10 and laser 11 are irradiated around the metal plates 2 and 4 to weld the edges. At this time, the irradiation of the air 10 causes cracks due to thermal diffusion to the container caused by the irradiation of the laser 11,
The purpose is to prevent warping, etc., and the air 10
The irradiation pressure and irradiation range are determined based on the amount of heat to be diffused. This laser welding device may be a carbon dioxide laser device, a YAG laser device, or the like.
この溶接による封着後、排気装置と前記表示装置の容器

Ｃ程度に昇温しで、ベーキングを行ない、その後封止を
行なう。After sealing by welding, connect the exhaust device to the container of the display device to evacuate, and then heat the display device to 200°C to 350°C in an electric furnace or the like.
Baking is performed by raising the temperature to approximately C, followed by sealing.
