ABSTRACT:
The present invention provides a cathode-ray tube provided with an electron gun capable of emitting electron beams of vertically elongate cross section.
A beam control electrode (G2) is fabricated by forming beam passage holes (22R, 22G, 22B) in thin portions (20R, 20G, 20B) of a reduced thickness of an electrode plate (18), and forming excess metal relieving slots (40R to 45B) on the opposite sides of the beam passage holes (22R, 22G, 22B), respectively. An electron gun employing the beam control electrode (G2) is capable of automatically correcting the cross section of beams so that the beams form substantially circular spots in the periphery of a screen. Thus, the deterioration of picture quality attributable to the distortion of the cross section of the beams can be avoided and pictures can be displayed in an improved picture quality.
