Claims

[Scope of utility model registration request]

In an electron gun for a color picture tube, comprising an electron beam generating means for generating three electron beams toward a phosphor screen, and a main lens for focusing the three electron beams on the phosphor screen, the main lens is configured. electrodes are provided at intervals from each other, and include two peripheral electrodes surrounding the three electron beams, and two partition plates each disposed close to opposing end surfaces of the peripheral electrodes. Each of the outer peripheral electrodes is composed of two semi-cylindrical polarization plates having axes on the optical axes of the electron beams on both sides, and a flat plate installed to connect the polarization plates to each other.
