Abstract:
A front substrate includes a phosphor screen including a plurality of phosphor layers arranged at a specific pitch in a first direction and at another specific pitch in a second direction intersecting at right angles to the first direction and including a light-shielding layer, divided metal-back layers laid on the phosphor screen and divided, in the first and second directions, divided getter films laid on the metal-back layer and divided, in the first and second directions, and a thin-film dividing layer formed on divided portions of at least one of the divided metal-back layers and the divided getter-films. Spacers are provided between the front substrate and a rear substrate and oppose to the thin-film dividing layer. Spacer-abutting layers are discretely arranged near the thin-film-dividing layer, at positions where the spacer-abutting layers abut the spacers.
