。In a display circuit equipped with a fluorescent display that is controlled to be able to emit light by applying a direct current positive voltage to a control grid, the display circuit includes a power switch that applies the direct current positive voltage to the control grid; a control switch circuit for cutting off the application of the direct current positive voltage to the control grid for a predetermined period; a first charge/discharge switch that grounds one end of the capacitor; and a second charge/discharge switch that is interlocked with the switch and grounds the other end of the capacitor when the capacitor is turned on, and applies the DC positive voltage to the other end of the capacitor when the capacitor is not turned on. A display circuit equipped with a charge/discharge switch.
