A plasma display panel which is free from defects such as a separation, crack or chip of a dielectric layer is disclosed. The plasma display panel comprises a first dielectric layer (7) covering display electrodes composed of a scan electrode and a sustain electrode formed on a front substrate (3), and a second dielectric layer covering a data electrode formed on a back substrate. The periphery of the first dielectric layer (7) and/or the second dielectric layer has a curvature radius other than 0.
