PURPOSE: To shorten a reset period and also to prevent excessive discharge in the reset period by reducing the variation of voltage increase rate due to the start of the discharge. CONSTITUTION: At the time of performing display by a plasma display panel 1 consisting of plural cells which emit light respectively with the discharge between one pair of display electrodes X, Y, at a bias period when a gradually increasing voltage is applied to the pair of the display electrodes by supplying a current from a constant current circuit 93 to the cell during the reset period for equalizing electric charges of all cells, a capacitive element C3 is connected in parallel to the cell and the output current Ic of the circuit 93 is distributed and supplied to the element C3 and the cell. |
