A plasma display panel has address properties stabilized. A priming
discharge is performed between auxiliary electrodes (18), which are
formed on a front substrate (1) and coupled with scan electrodes (6), and
priming electrodes (14) formed on a back substrate (2). And on the front
substrate (1), a dielectric layer (4) is made thinner in regions
corresponding to priming cells (gap parts 13) than in regions
corresponding to cell parts (11). As a result, the priming discharge has
a wider margin, and a supply of priming particles to the discharge cells
is stabilized, whereby a discharge delay during the addressing is
reduced, and the address properties are stabilized.
