    • A shadow mask for a cathode ray tube has an effective screen portion having a plurality of beam passage holes arranged in a predetermined pattern, and an inactive portion with no beam passage holes. The length of a beam passage hole at a column adjacent to a division between the effective screen portion and the inactive portion (hereinafter “the beam passage hole length”) in the long-sided direction is set to be smaller than the length of a beam passage hole placed at the short-sided center of the column. The beam passage hole length “a” at columns which are even-numbered from the long-sided center of the effective screen portion is set to satisfy the condition of 1>a/A≧0.45, compared to the length A of the beam passage hole placed at the short-sided center of relevant columns. The beam passage hole length “b” at columns which are odd-numbered is set to satisfy the condition of 1>b/B≧0.35, compared to the length B of the beam passage hole placed at the short-sided center of relevant columns.
    • 用于阴极射线管的阴罩具有有效屏幕部分,其具有以预定图案布置的多个光束通过孔以及没有光束通过孔的无效部分。 与长边方向的有效屏幕部分和非活动部分之间的分界面(以下称为“光束通过孔长度”)相邻的列处的光束通过孔的长度被设定为小于光束的长度 通道孔位于柱的短边中心。 与有效屏幕部分的长边中心偶数编号的列的光束通过孔长度“a”设置为满足条件1> a / A> = 0.45,与光束的长度A相比 通孔位于相关柱的短边中心。 奇数列的光束通过孔长度“b”设定为满足条件1> b / B> = 0.35,与放置在相关的短边中心处的光束通过孔的长度B相比 列。
