A plasma display panel (PDP). The PDP includes corresponding pluralities of address and sustaining electrodes provided on respective front and rear substrates. Barrier walls are formed at regular intervals to divide the substrates into individual discharge cells. Respective engaging portions are provided on the address electrodes and on the substrate to which the address electrodes are attached so as to improve the adhesion between the substrate and the address electrodes. In one embodiment, the engaging portions are portions with complementary sets of grooves.
