A plasma display panel includes a first substrate and a second substrate, the first substrate and the second substrate being provided with a predetermined gap therebetween. Barrier ribs are formed in a non-striped pattern between the first substrate and the second substrate, the barrier ribs defining a plurality of discharge spaces. A plurality of address electrodes are formed on the first substrate along a direction (y), the address electrodes being formed within and outside discharge spaces. A plurality of sustain electrodes are formed on the second substrate along a direction (x), the sustain electrodes being formed within and outside discharge spaces. The address electrodes include large electrode portions provided within discharge spaces and small electrode portions provided outside the discharge spaces. If a width of large electrode portions is AW, a width of small electrode portions is Aw, and a distance between barrier ribs along direction (x) is D, AW is larger than Aw, and AW is 40-75% of D.
