Abstract:
A color cathode ray tube comprising an evacuated envelope comprising a panel portion having a phosphor screen formed on an inner surface thereof, a neck portion, and a funnel portion connecting said panel portion and said neck portion, andan electron gun housed in said neck portion comprising at least one cathode and a plurality of focus grid electrodes including grid electrodes for forming a multistage focus lens for focusing at least one electron beam emitted from said at least one cathode,said at least one cathode and said plurality of focus grid electrodes being fixed in predetermined axially spaced relationship by a pair of bead glass, whereinsaid electron gun is provided with a voltage divider for producing at least one voltage other than a voltage supplied from outside said evacuated envelope therefrom,said voltage divider being made of at least one resistor and being fabricated as a separate element from said pair of bead glass,and at least one of said pair of bead glass is provided with a recess for receiving said voltage divider in a surface thereof on a side thereof facing away from said at least one cathode and said plurality of focus grid electrodes.
