という問題があった。Furthermore, a connection terminal 16 from the electron beam control means
In No. 24, a strip-shaped terminal of a glass sealing metal was treated with chromium oxide and removed from the adhesive surface of a glass container. Therefore, since there are a large number of terminals, there are problems such as vacuum leakage from the adhesive surface of the glass container, poor positional accuracy that tends to cause short-circuits between the terminals, and difficulty in connecting to a printed wiring board.
そこで、本発明は、上記課題に鑑み蛍光体スクリーンと

In addition, high voltage discharge is eliminated by increasing the distance between the phosphor screen, the terminal on the low 1E voltage side, and others along the inner surface of the container. Moreover, the metal container can be easily attached to the cabinet by providing a hole in the metal container. Terminal reliability is improved by providing a wiring pattern on the insulating film.

ネット（図示せず）に取り付ける。Embodiment Hereinafter, an image display device according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows the configuration of an image display device in an embodiment of the present invention. In FIG. 1, 1 is a glass container and 2 is a metal container. This metal container 2 is made of a so-called sealing metal in order to match the thermal expansion coefficient with that of glass. An electron beam control means 3 is disposed within the containers 1 and 2 by being attached by welding or screws using a fixing fitting 4 which is attached to the container 2 by means of welding or the like. Further, the container 1 is provided with a phosphor screen 5 on the inner surface of its transparent portion. An insulating film e is provided on the container 2 except for the part where the fixing fitting 4 is attached. This insulating film 6 can be formed by screen printing a glass adhesive, by thermal spraying a ceramic material, or by other methods. Further, on this insulating film 6, a wiring pattern is provided from the inside to the outside of the container 1.degree. This wiring pattern 7 can be formed by a method such as thick film printing. The wiring pattern 7, a plurality of terminals of the electron beam control means 3, and the container 1,
Connected within 2. Further, the containers 1 and 2 are pasted together using a glass adhesive 8, and the insides of the containers 1 and 2 are maintained in a vacuum. Further, the container 2 is attached to a cabinet (not shown) through holes 9 provided at the four corners.
次に、この一実施例の構成における作用を説明する。Next, the operation of the configuration of this embodiment will be explained.
まず、金属容器２に電子ビーム制御手段３がバネを介す
ることなく固定金具４で固定されているため経時的な位
置ずれが起こらない。また、金属に溶接で固定金具４を
取り付けているため衝撃。First, since the electron beam control means 3 is fixed to the metal container 2 by the fixing fitting 4 without using a spring, positional shift does not occur over time. Also, the fixing bracket 4 is attached to the metal by welding, which causes a shock.
振動にも強くなっている。１だ、従来例で示したような
容器の側壁に固定用のビンがないため、高電圧がかかる
蛍光体スクリーンと低電圧側との距離が取れるため高電
圧の沿面放電が防げる。It is also resistant to vibration. 1. Since there is no fixing bottle on the side wall of the container as in the conventional example, there is a distance between the phosphor screen to which high voltage is applied and the low voltage side, which prevents high voltage creeping discharge.
次に、配線パターン７を設けたことにより、従来の金属
端子を容器１．２の接着面に挾むのに比べ真空の信頼性
が向上した。壕だ、従来の金属端子の変形による端子位
置のずれ、及び端子間ショートも生じない。Next, by providing the wiring pattern 7, vacuum reliability is improved compared to the conventional method in which metal terminals are sandwiched between the adhesive surfaces of the container 1.2. There are no holes, no misalignment of terminal positions due to deformation of conventional metal terminals, and no short-circuits between terminals.
