FIG. 1 is a partial cross-sectional view of the anode substrate and grid of a conventional fluorescent display tube.
An insulating layer 2, graphite dots 8, graphite segments 4, and a phosphor 3 are provided on the
The grid 5 was shaped and provided with legs 5a, 5b, and the legs 5a, 5b of the shaped grid were fixed on the insulating layer 2 of the anode substrate with a low melting point glass 6. The leg portion 5b on one side was electrically connected to the silver terminal 9 of the conductor provided on the anode substrate, and the leg portion 5a on the other side was simply fixed to the anode substrate without establishing electrical continuity. Also, the insulating layer 2 at the fixing part of the leg part 5a on the opposite side, which does not need to be electrically conductive,
An aluminum wiring 7 was provided in the lower layer.
〔考案が解決しようとする問題点〕

してしまうことがあるという欠点があつた。[Problems to be Solved by the Invention] In the structure of the fluorescent display tube described above, since the coefficient of expansion of the material of the grid 5 and the coefficient of expansion of the insulating layer 2 are different, minute cracks occur on the upper surface of the insulating layer.
Since the minute cracks extend to the lower side of the insulating layer 2, there is a drawback that the aluminum wiring 7 provided under the insulating layer may be cut.
本考案の目的は、グリツドの固定部の下層に、

The present invention provides a fluorescent display tube with a structure in which the legs of the grid are fixed on the anode substrate using low-melting glass.
The present invention is characterized in that there is no wiring of the anode substrate under the low melting point glass that fixes the leg portions that are not electrically connected to the wiring on the anode substrate.
次に本考案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.
第２図は、本考案の一実施例であつて、第１図

７を配線する。 FIG. 2 shows an embodiment of the present invention, in which a plurality of aluminum wires 7 were conventionally provided under the legs 5a of the insulating layer 2 as shown in FIG. By reducing the pitch by 0.1 mm, the aluminum wiring 7 is routed avoiding the lower layer where the legs 5a of the insulating layer 2 are fixed.
これにより、グリツド５の脚部５ａの固定部の
下層に絶縁層２の微小なクラツクが生じても、ア
ルミ配線７の断線が生じない様にできる。 Thereby, even if a minute crack occurs in the insulating layer 2 below the fixed portion of the leg portion 5a of the grid 5, the aluminum wiring 7 can be prevented from breaking.

５ｂと絶縁層２との直接の接触はなく、絶縁層２
に微小クラツクは生じない。 Note that on the side of the leg portion 5b of the shaped grid 5 described above that establishes conduction with the silver terminal 9, in order to interpose the conductive paste 1 between the leg portion 5b and the insulating layer 2, the leg portion 5b and the insulating layer 2 are connected to each other. There is no direct contact with the insulation layer 2.
No microcracks occur.
本実施例では絶縁層２の下層にアルミ配線７を
