摘要： A color cathode ray tube having at least an electron gun and a fluorescent screen. The electron gun forms a plurality of electron beams arranged in line and includes a focusing electrode and an anode having a gap and providing a main lens for focusing and accelerating the electron beams. The focusing electrode includes at least a first division electrode and a second division electrode having the same potential and arranged with a gap in the axial direction of the tube. The second division electrode is opposed to said anode and has, in the opposed surface thereof, a single opening for passing the plurality of electron beams in common. The second division electrode is opposed to the first division electrode and has, in the opposed surface thereof, individual electron beam passing openings for the respective electron beams. The length of the second division electrode in the axial direction of the tube is shorter than the length of the first division electrode in the axial direction of the tube and the diameter of the individual electron beam passing openings in the surface of the second division electrode opposed to the first division electrode is smaller than the diameter of the single opening in the surface of the second division electrode opposed to the anode in a direction at right angles with the in-line direction. The length of the second division electrode in the axial direction of the tube is not smaller than the diameter of the single opening in a direction at right angles with the in-line direction.
