Abstract

A plasma display panel has a display region and a non-display region formed around the display region. The rear plate has data electrode that applies a drive voltage to the rear plate, a dummy electrode that is in parallel with the data electrode and does not apply a drive voltage to the rear plate, an insulating layer that coats the data electrode and the dummy electrode, and a plurality of horizontal barrier ribs formed on the insulating layer and orthogonal to the data electrodes. The data electrode is arranged in the display region and the non-display region. The dummy electrode is arranged in the non-display region. An outermost horizontal barrier rib is arranged in the non-display region. The outermost horizontal barrier rib is opposed to the data electrode via the insulating layer, and is not opposed to the dummy electrode.
