Problems to be Solved by the Invention However, with such a structure, the first regulating member 11
2a and 112b are fixed by a connecting plate 109, but the second regulating members 113a and 113b are connected to the regulating grooves 118a and 1.
Since the partition plate 11o is not fixed by the diaphragm 18b, the electrode assembly 104 is unstable.
This causes a deviation from the black line 120 of the screen 108, significantly deteriorating the image.

In view of this point, the present invention constitutes a stable electrode structure and can provide a good image.
