摘要： In an electron gun including a cathode, a control electrode, an acceleration electrode G2, a focusing electrode G3 and an anode, longitudinally elongated concave SL-V which surround an electron beam aperture G2-H and have a long axis in the vertical direction is formed at a focusing electrode G3 side of the acceleration electrode G2, and an electron beam aperture G3-BH formed at the acceleration electrode G2 side of the focusing electrode G3 is formed in a longitudinally elongated shape having a long axis in the vertical direction. Due to such a constitution of the present invention, non-uniformity of the beam spot shape attributed to a deflection quantity can be reduced whereby the optimum focusing can be realized over the whole area of a screen.

摘要： A cathode ray tube is provided having an electron gun equipped with a main lens having a function of controlling a shape of an electron beam spot which is deflected to the peripheral portion of a display screen, to improve a resolution at the peripheral portion of the screen of the cathode ray tube for use in a direct view color television receiver or a color display terminal. To reduce the dynamic correction voltage of the electron gun, an electrostatic quadrupole lens with a simple structure is used, thereby reducing deterioration due to the deflection aberration of the electron beam spot at the peripheral portion of the screen.
