摘要： A novel electron gun for the color picture tube is disclosed, which comprises at least a cathode for emitting three electron beams in alignment and focusing electrodes for focusing the electron beams emitted from the cathode. The forcusing electrodes include first and second focusing electrodes for passing electron beams. The first focusing electrode includes a plurality of perpendicular plate electrodes arranged in such a manner as to sandwich the electron beams along the direction of arrangement thereof after being passed through the passage apertures and rim electrodes surrounding the perpendicular plate electrodes. The second focusing electrode includes a couple of horizontal plate electrodes arranged in such a manner as to hold the electron beams along the direction perpendicular to the direction of arrangement thereof after being passed through passage apertures and extending in opposed relationship with the perpendicular plate electrodes and rim electrodes along tht electron gun axis. The resolution of the peripheral parts of the display surface of the picture tube is thus improved and the assembly of the electron gun thereof is facilitated.

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.
