| abstract |
(57) [Abstract] [Purpose] To prevent the reduction of the vertical halo suppressing effect at the peripheral portion of the screen by the second grid electrode having slits. [Structure] Electron beam passage hole 1a of second grid electrode 2 Is a rectangular hole formed in the center of the slit 1b having a long side in the horizontal direction, and the vertical width d of the rectangular hole is larger than the short side width w of the slit. [Effect] The effect of suppressing the vertical halo in the peripheral portion of the phosphor screen can be improved, and the focus characteristic in the peripheral portion of the phosphor screen can be made substantially equal to that in the central portion. |
