PURPOSE:To reduce the allowance loss of a driver element and to reduce energy consumption by maintaining an address electrode at the level of a write voltage without executing down drive to an address electrode. CONSTITUTION:During the period of write to a display line 71, a driver element 38 is turned on, a driver element 39 is turned off, a voltage Va is impressed to an address electrode 41, the address electrode 41 is up driven, the level of a Y electrode 31 is lowered from a Vs level to a GND level, a discharge start voltage is impressed to a cell, write discharge is executed at the cell, and wall charges are stored at the cell. In this case, a charging current flows to the driver element 38. Afterwards, the driver element 38 is turned off, the address electrode 41 is turned to a high impedance state, the Y electrode 31 is returned to the Vs level, an X electrode 2 is turned from the Vs level to the GND level, and a maintaining state is executed at the cell.
