PURPOSE: Plasma display with improved contrast is provided, which substantially obviates one or more of the problems caused by the limitations and disadvantages of the related art. CONSTITUTION: Reset discharge is not performed at all in the present invention if the black level is repeatedly displayed without any display data. At portions where the black level is displayed, therefore, a luminance level almost equal to 0 cd/m¬2 is achieved. When display data is input in a given frame, a display data detection unit detects the presence of display data. In the manner, it is learned that a normal form of displaying is to be performed during the next vertical synchronization period. At the start of a frame that coincides the beginning of normal displaying, a reset scanning discharge is performed. This creates a seeds effect that forms a basis for reliable address discharge in the subsequent sub-field.
