    • Assuming an aperture diameter of an electron beam aperture formed in a shield cup as Vsc, an aperture diameter of an electron beam aperture formed in an inner electrode of a focusing electrode as V5, and a distance between the electron beam aperture formed in the shield cup and the inner electrode as L, the above-mentioned aperture diameter Vsc, the aperture diameter V5 and the distance L are determined to satisfy tan θ=(V5−Vsc)/2L≧0.08. Due to such a constitution, it is possible to enhance the degree of vacuum in the inside of a cathode ray tube and, it is possible to prevent a getter for elevating the degree of vacuum in the inside of the cathode ray tube and for maintaining the elevated degree of the vacuum from being scattered to the electron gun side thus preventing the deterioration of the characteristics of the electron gun.

    • 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.
