Abstract
A plasma display panel having an improved display quality with low power consumption is provided. Pairs of first and second sustain electrodes are formed on the inner surface of a first substrate to extend in a first direction. A first dielectric layer is formed on the inner surface of the first substrate to cover the pairs of first and second sustain electrodes. Selection electrodes are formed on the inner surface of a second substrate to extend in a second direction perpendicular to the first direction. A second dielectric layer is formed on the inner surface of the second substrate to cover the selection electrodes. Partition walls are formed in the gap between the first and second substrates to extend in the second direction, thereby forming discharge spaces in the gap. Fluorescent layers are formed in the respective discharge spaces. A discharge gas is introduced in the discharge spaces. An overlapping part of the first dielectric layers with the first sustain electrodes has a non-uniform thickness in the widthwise direction of the first sustain electrode. An overlapping part of the first dielectric layers with the second sustain electrodes has a non-uniform thickness in the widthwise direction of the second sustain electrode. The non-uniform thickness is realized by protrusions or depressions for the first dielectric layer.
