    • For a drive circuit of a sustaining discharge circuit of an AC plasma display panel, an idea of current flow parts arrangement is provided to reduce inductance. The configuration includes a plasma display panel on which electrodes are formed, an electric conductive conductor for fixing the panel, a pair of circuit boards fixed onto the conductor using a plurality of fixing members, ground terminals and electric power supplies disposed respectively for the circuit boards, and a pair of connecting circuit boards connected to end portions respectively of the circuit boards and an end portion of the panel. The ground terminals are electrically connected via fixing members to a position near an end portion of the conductor.
