Electron gun for cathode ray tube having SVM coil and cathode ray tube having the electron gun

An electron gun for a cathode ray tube including a scanning velocity modulation coil mounted on an outer circumference of a neck of the cathode ray tube, the electron gun comprising:

• a cathode for emitting an electron beam;
• a plurality of grid electrodes sequentially arranged starting from the cathode, and including a plurality of focus electrodes arranged with a predetermined gap therebetween;
• a support on which the plurality of grid electrodes are fixed in a row;
• and
• a shield electrode configured between the plurality of focus electrodes and connected to the plurality of focus electrodes,
• wherein the shield electrode comprises a pair of opposing electrodes leaving a plurality of first slots in between, each of the first slots forming a continuous space between the pair of opposing electrodes in a direction substantially parallel to a long axis direction of the cathode ray tube, and
• wherein each of the opposing electrodes includes a plurality of second slots formed along a direction different from the direction of the first slots.
