PROBLEM TO BE SOLVED: To mutually offset the electromagnetic field radiation produced by impulse current and suppress the generation of unnecessary electromagnetic field radiation, by composing a panel electrode arrangement, a driver circuit and a driver circuit wiring, by which the impulse currents generated in the period of maintenance discharge are made to flow in the parallel and reverse directions. SOLUTION: When the voltage of a high-voltage pulse generator on the scanning side rises and the voltage of a high-voltage pulse generator 17 on the maintenance side falls, an impulse current is made to be generated along the current paths 11, 12 by the current flowing from the generator 19 to the generator 17. Because of this, current in the paths 11, 12 are generated simultaneously in alternately reversed directions in the route of the generator 19, a scanning driver 18, a scanning electrode 3, a maintenance electrode 4 and the generator 17 in this order. As the results, the electromagnetic field radiations generated from the impulse currents of these neighboring current paths 11, 12 can be mutually offset. |
