Abstract

PURPOSE:To prevent the charge-up at a gap section by providing an external electrode on the outer face of a glass bulb facing the surface formed with an arrow pattern-shaped deflecting electrode and applying the negative potential to it. CONSTITUTION:An external electrode 19 is provided on the outer face of a glass bulb 1 facing the surface formed with at least an arrow pattern-shaped deflecting electrode G4, and the negative potential is applied to it. The energy of an electron beam is considerably larger at gap sections generated between electrodes constituting an electron gun, particularly at the gap section of the arrow pattern-shaped deflecting electrode G4, than at a cathode, thus when the potential of the face of the glass bulb 1 corresponding to this portion is made negative to the cathode potential, the electron beam entering this portion is decelerated and repulsed. The charge-up at the gap section can be thereby prevented.
