Abstract

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.
