PROBLEM TO BE SOLVED: To provide a plasma display device in which regulation of power source voltages is improved and the reactive power of a dropper power source circuit is reduced. SOLUTION: This plasma display device has a PDP(plasma display panel) 11, a display driving circuit part performing display by impressing signals to the PDP 11 and a power source circuit part supplying a plurality of power source voltages required for the display driving circuit part. In this display device, since a flyback system secondary regeneration converter circuit 1224 which stabilizes output power source voltages by regenerating secondary-side energy at a primary side is provided in the power source circuit part and the secondary-side excessive energy is made to be regenerated at the primary side while making a voltage having a large output load and a large load fluctuation a stabilizing voltage, it is possible to keep the transmission amount of energy from the primary side to the secondary side always constant and regulation of secondary-side output voltages can be made to be stabilized output voltages.
