び表示面ガラス容器１４により構成されている。(Structure of conventional example and its problems) In a previous patent application, a flat image display device having a structure as shown in FIG. 1 was proposed. This image display device includes a plurality of linear hot cathodes 1. Cathode back electrode 2. Electron beam extraction electrodes 3, 4. Vertical deflection electrode5. Grid electrodes 6, 8
,10. Strip-shaped electrode 7, horizontal deflection electrode 9. Electrode 11° metal back layer 12 to facilitate deflection. It is composed of a phosphor layer 13 and a display glass container 14.

They must be arranged parallel to the slits of the electron beam extraction electrodes 3 and 4 at equal intervals. However, since the vertical deflection electrodes 5 are constructed by depositing or imprinting metal on an insulating thin plate, such as a glass plate, arranging them parallel to each other and to the linear hot cathode 1 is difficult because the material itself It is extremely difficult to remove due to slight bending, processing distortion, etc. Further, the electron beam extracting electrodes 3 and 4 are made of metal, and the vertical deflection electrode 5 is made of an insulating material such as glass, which have different coefficients of thermal expansion. Therefore, they must be fixed by a method that does not cause misalignment or distortion during the heating process, such as sealing with frit glass or glass.

A number of pairs have been installed. Vertical deflection electrode 17
is fitted into the guide 16 to correct burrs, warps, ridges, etc., and is arranged parallel to the slit of the electron beam extracting electrode 15. The vertical deflection electrode 17 is an insulating thin plate with metal vapor-deposited or printed on the part 17a, and is fixed to the shimiko beam extraction electrode 15 only at the position a on one side in the horizontal direction. The difference in thermal expansion between the electrode and the electron beam extraction electrode during processing such as sealing is absorbed by sliding along the guide 16, and no displacement occurs.
