A surface-discharge type PDP includes plural electrode pairs formed of first and second sustain electrodes arranged on a first substrate. Each pair extends along a line direction, and the first and second sustain electrodes are in parallel and adjacent to each other. Plural address electrodes arranged on a second substrate opposing the first substrate via a discharge space, each extending along a row direction, a matrix corresponding to a screen to be displayed is formed with the main electrodes and address electrodes, the address electrodes are orthogonal to the main electrodes, each of the address electrode is divided into, for example two partial address electrodes separated from each other by a border line located between adjacent main electrode pairs, whereby the screen is divided into two partial screens, wherein a first clearance between the partial address electrodes is substantially larger than a second clearance between main electrode pair adjacent across the border line. The arrangement order of the first and second sustain electrodes may preferably be such that first sustain electrodes of the first and second partial screens face each other via the border line, and the partial address electrodes may not cross over the first sustain electrodes nearest to the border line.

In an AC-type PDP including first and second sustain electrodes extending along a line direction via a discharge slit; a discharge space; a dielectric layer coated on the first and second sustain electrodes, and an address electrode orthogonal to the first and second sustain electrodes via the dielectric layer, wherein the first and second sustain electrodes comprise first and second belt-like first and second metal electrodes thereon, respectively, where the first and second metal electrodes are narrower than the first and second transparent electrodes, respectively, wherein the first metal electrode is located on an edge apart from the discharge slit; and the second metal electrode is located on another edge near to the discharge slit. Moreover, then, a distance between the second sustain electrode and said address electrode may be smaller than a distance between said first sustain electrode and said address electrode. A gap between the second sustain electrode and the address electrode may be smaller than a clearance between the first sustain electrode and the address electrode. A rise time of a first sustain pulse which makes the second sustain electrodes negative with respect to the first sustain electrode is preferably slower than a second rise time of a second sustain pulse which makes the second sustain electrodes positive with respect to the first sustain electrode.
