Abstract
A technology capable of preventing or suppressing a display defect in a PDP (detrimental effect due to local contamination of the display area caused by admixture of impurity gas at the time of introducing discharge gas) is provided. In a PDP, first barrier ribs and first phosphors formed between the first barrier ribs are provided so as to correspond to a display area. In a non-display area outside the display area, an air hole for evacuation from a discharge space and gas filling into the discharge space is provided in a part of an outer perimeter of the panel. Further, an area in which second phosphors having a property of absorbing impurity gas are formed is formed at a position between the display area and the air hole in a part of the non-display area, in particular, in a part of a dummy rib area.
