つて生ぜしめることを特徴とする偏平型受像管。 A four-pole magnetized annular magnet is coaxially provided in the electrode array of an electron gun whose center axis is on an axis inclined with respect to the fluorescent surface, and the inclination of the electron beam emitted from the electron gun is adjusted. A flat picture tube characterized in that the magnet generates a quadrupole magnetic field for reducing the diameter in a direction and increasing the diameter in a direction perpendicular to the same direction.
