Abstract: A row electrode in a row electrode pair has a bus electrode extending in the row direction and transparent electrodes each facing a transparent electrode in its counterpart row electrode in each discharge cell. The opposing portions of the transparent electrodes facing each other across a discharge gap are inclined at a required angle either in the clockwise direction or the counterclockwise direction relative to the row direction of the panel. The transparent electrodes with the opposing portions inclined in opposite directions are arranged in alternate positions along the associated bus electrodes and the transparent electrodes with the opposing portions inclined in the same direction face each other.
