Abstract

A plasma display panel can reduce a discharge delay in address discharge, thereby performing high-speed addressing in a stable manner. A front substrate ( 1 ) and a back substrate ( 2 ) are disposed to face each other, and a discharge space ( 3 ) is formed and partitioned by barrier ribs ( 10 ) so as to form priming discharge cells ( 17 ) and main discharge cells ( 11 ). A clearance ( 19 ) is provided between the barrier ribs ( 10 ) of the priming discharge cells ( 17 ) and the front substrate ( 1 ), and priming particles generated in the priming discharge cells ( 17 ) are supplied to the main discharge cells ( 11 ) through the clearance ( 19 ), whereby a PDP performing high-speed addressing is obtained.
