To provide a plasma display panel that can improve the bright room contrast.The PDP of the present invention provided with a discharge space formed between a front-side substrate assembly and a rear-side substrate assembly, wherein the front-side substrate assembly has a plurality of display electrodes for defining lines of a screen, and the rear-side substrate assembly has a plurality of barrier ribs for partitioning the discharge space in a column direction, and a phosphor layer that is applied to side surfaces and a bottom surface of each of grooves formed between the barrier ribs, the plasma display panel is characterized in that each of the display electrodes for defining the lines comprises a belt-like base portion that extends over an entire length of the screen in a line direction, and a plurality of projections that projects from the base portion toward another display electrode adjacent thereto, each projection having a width the same as or narrower than a width of a bottom of the phosphor layer, and having a visible light transmittance ranging from 0% to 80% inclusive.
