Abstract
A cathode ray tube includes an electron gun having plural focus electrodes and an anode in its neck portion, a voltage-dividing resistor for producing an intermediate voltage applied to a first one of the focus electrodes adjacent to the anode by dividing an anode voltage, a metal conductor attached to a second one of the focus electrodes to surround the voltage-dividing resistor, and a metal film on an insulating substrate of the voltage-dividing resistor between the metal conductor and an intermediate-voltage terminal of the voltage-dividing resistor. The second one of the focus electrodes is disposed upstream of the first one of the focus electrodes, and the metal film extends at least 1 mm axially and is spaced at least 1 mm from the metal conductor.
