A cathode ray tube includes a bulb (50) having a screen (52), a conductive layer (53) coated on the inner surface of the bulb, an electron gun (60) mounted in the neck portion (54) and having a final accelerating electrode (61) electrically connected to the conductive layer. Leakage current shielding means (81-83) are installed in the neck portion (54), for shielding leakage current flowing along the inner surface of the neck portion from the conductive layer (53). <IMAGE> |
