ABSTRACT:
A plasma display panel includes first and second substrates opposed to each other for defining a space filled with discharge gas, a screen made up of cells arranged in the row and column directions, display electrodes arranged on the first substrate, the display electrodes extending in the row direction, band-like partitions arranged in parallel on the second substrate for dividing the gas filled space into columns, and fluorescent material layers sticking to side faces of the partitions and inner surfaces between the partitions on the columns, each of the fluorescent material layers extending across cells. The thickness of the fluorescent material layer at a part sticking to the side face of the partition and overlapping with the display electrodes is designed to be smaller than the thickness at a part sticking to the side face of the partition in the vicinity of the surface discharge gap.
