Abstract
An electrode of an electron gun for a cathode ray tube with an improved structure so as to enhance the flatness of the electrode. The electrode includes an electron beam passing plane on which one or more electron beam passing holes are formed, an upper sloping portion of a truncated cone shape, slantingly extending downward and outward from the peripheral edges of the electron beam passing plane, and a vertically extending portion of a cylindrical shape, extending downward from the lower portion of the upper sloping portion and extending substantially perpendicular to the electron beam passing plane.
