Abstract
A CRT is provided with a panel having a curved inner phosphor-coated side, a substantially flat outer viewing screen side and a rectangular-shaped effective screen area ranged through the inner phosphor-coated side and the outer viewing screen side. A shadow mask faces the phosphor-coated side of the panel. The shadow mask is formed to the curved shape of the phosphor-coated side. The rectangular-shaped effective screen area of the panel has two horizontally parallel long sides meeting a vertical axis, two vertically parallel short sides extended perpendicular to the horizontal sides, and four boundary corners formed between the neighboring horizontal and vertical sides. The vertical sides meet a horizontal axis and each of the boundary sides meets a diagonal axis. The meeting point of a horizontal long side and the vertical axis has a thickness Tv. The meeting point of a vertical short side and the horizontal axis has a thickness Th. The meeting point of a boundary corner and the diagonal axis has a thickness Td. The thickness ratio of Tv to Td is in the range of 0.75≦Tv/Td≦0.93, whereas the thickness ratio of Th to Td is in the range of 0.75≦Th/Td≦0.85.
