PROBLEM TO BE SOLVED: To provide a power recovery circuit capable of suppressing the malfunctions of a switching element, and to provide also a plasma display. SOLUTION: The power recovery circuit is provided with a capacitor C2 for storing power collected from a panel C1, a switching element Q3 for discharging the capacitor C2, a switching element Q4 for charging the capacitor C2, and a level-shift part 28 for shifting a control signal for controlling a second switch to the voltage level of the capacitor C2, and the threshold voltage of the switching element Q4 is set higher than the threshold voltage of the switching element Q3. Thereby generation of malfunctions in the switching element Q4 due to the voltage drop of the capacitor C2 can be prevented. COPYRIGHT: (C)2006,JPO&NCIPI
