Abstract

PURPOSE:To prevent generation of halation by making a mesh electrode consist of a strand whose cross section is semicircular, facing the semicircular section to the phosphor screen side, and forming a concave at the flat section on the electron gun side. CONSTITUTION:One primary surface 211 of a glass substrate 21 is mirror-surface- lapped and a chrome coat is formed. This glass substrate 21 is mounted in a vacuum container and a master mesh 22 is formed by the electron beam plotting method. Then, after the surface of the master mesh 22 is cleaned, an almost semicircular nickel mesh 23 is formed using the nickel sulfamate plating solution containing cobalt ion or nickel sulfate. Then, this mesh 23 is peeled off and a dome- shaped mesh electrode 24 is formed so that the semicircular section can face the phosphor screen side. As a result, the semicircular section on the phosphor screen and the concave formed at the flat section on the electron gun control the scattering toward the phosphor screen side and reduce halation.
