Plasma display panel

The present invention provides a plasma display panel (PDP) having an improved impact resistance, the PDP including: a front substrate (14) on which sustain electrodes (15) are disposed at predetermined intervals; a front dielectric layer (16) covering the sustain electrodes; a rear substrate (10) that is disposed to face the front substrate, and on which address electrodes (11) are disposed to cross the sustain electrodes; a rear dielectric layer (12) covering the address electrodes (11); barrier ribs (19) formed between the front substrate and the rear substrate, the barrier ribs defining discharge spaces; and phosphor layers (13) formed in the discharge spaces, wherein the front dielectric layer (16) is formed of a lead-free material and has a Vickers hardness of 350 to 500 Hv, the front dielectric layer comprising at least two selected from the group consisting of B 2 O 3 , SiO 2 , Bi 2 O 3 , ZnO, and Al 2 O 3 , or at least two selected from the group consisting of B 2 O 3 , SiO 2 , BaO, ZnO, Al 2 O 3 , P 2 O 5 .
