摘要： An electron gun used in a cathode ray tube, for example, color television picture tube, is disclosed. The electron gun has a plurality of electrodes aligned in one direction along an axis of a neck portion of the cathode ray tube. Each of the electrodes is supplied with a suitable potential for focusing and accelerating an electron beam derived by a cathode. A resistance element which comprises a ceramic substrate coated with a layer of resistive material is provided along and adjacent to the electrodes in the cathode ray tube. One end of the resistance element is electrically connected to the anode potential, and another end is connected to a stem lead pin which is at a substantially low enough potential to avoid mutual electric discharge between stem lead pins. Suitable potential for the selective electrodes is derived from intermediate taps of the resistor and electrode material are composed of a mixture of RuO.sub.2 and glass frit. The resistor is overcoated with a glass layer on the surface of the layer of resistive material and the coefficient of thermal expansion of the substrate and glass layer chosen to be similar.
