PURPOSE:To stably supply the potential different from the other mask by arranging a conductive terminal on a part on the envelope side of the earth magnet sealded part through an insulating mechanism while supplying the potential to one of the masks by relaying it. CONSTITUTION:Of the first mask 8 and the second mask 7 having a large number of apertures 14 facedly provided with the fixed intervals on a screen 1 of a mask focusing type color picture tube, the anode high voltage is impressed on the mask 8 by making to contact with a conductive film 9 of a funnel 3 inner wall through a frame 16 by a connector 21, while the voltage slightly lower than the anode high voltage on a conductive terminal consisting of an insulating layer 31 and a metal piece 32 provided on a part on the funnel 3 side of the earth magnet shield 30 is impressed on the mask 7 with a connector 33 from a button 20 through a lead wire 22. Accordingly, the different voltage can be extremely simply and stably given to masks 7 and 8 excluding a disadvantage such as strain of an electric field or the like. |
