In a PDP device, a technique capable of more efficiently performing address energy control according to contents of a display image (display data) to reduce the address energy. In the PDP device, as an address energy recovery circuit, a plurality of address energy control circuits (B1 to Bn) are provided corresponding to a plurality (n) of regions (H1 to Hn) into which a screen area (R) and a group of address electrodes are divided in a horizontal direction. For each of the regions (H) of which the address energy recovery circuits (B) are respectively in charge and for each of subfields, an address pulse switching load (Q) corresponding to that region (H) is determined, and then, according to the magnitude of the load (Q), the operation of the address energy recovery circuit (B) is ON/OFF-controlled.
