Plasma display device and capacitive load driving circuit

A plasma display device, comprising:

• a first display electrode;
• a second display electrode adapted to cause a discharge to occur between the first display electrode;
• a first display electrode drive circuit to apply a discharge voltage to the first display electrode;
• and
• a second display electrode drive circuit to apply a discharge voltage to the second display electrode, wherein the first display electrode drive circuit comprising;
• a first modulation circuit to modulate and output a signal to be inputted from a first input terminal;
• a first transformer which has a primary winding and a secondary winding, the primary winding being connected to the output of the first modulation circuit;
