。 a full-wave rectifier circuit connected to a first secondary winding of a power transformer to which an alternating current input is applied to obtain a direct current voltage to be supplied to the grid terminals and segment input terminals of the fluorescent display tube; It is equipped with first and second half-wave rectifier circuits that share the center tap of the second secondary winding of the transformer, and the rectified voltage from the first half-wave rectifier circuit is applied to the grid and segment when the grid and segment are not lit. A power supply circuit for a fluorescent display tube, characterized in that the voltage applied to the filament is the rectified voltage of the second half-wave rectifier circuit, which is always at a more positive potential than the applied voltage. .
