Abstract

PURPOSE: To facilitate the formation of index stripes by disposing a slotted plate inside the fluorescent screen with the apertures facing opposite to the color fluorescent substance.
CONSTITUTION: A fluorescet screen 23 is consisited of alternate black stripes 25 and color stripes 26 provided on a glass face 29. Apertures 27 are formed on a slotted plate 24 at a pitch equal to that of black stripes 25. The aperture pitch Ps and the triplet pitch Pt on the fluorescent screen consist an equation; Ps≃Pt/3. The slotted plate 24 is disposed with its apertures facing opposite to the color stripe fluorescent substance 26. Accordingly, electron beams aiming the black stripe area are absorbed by the slotted plate 24 as the apertures 27 are arranged at a pitch equal to that of the black stripes 25.
