Plasma display panel and method of manufacturing the same

A plasma display panel comprises a front substrate; a rear substrate spaced apart from the front substrate; a plurality of barrier ribs formed between the front and rear substrates, defining discharge cells therebetween; a plurality of sustain electrode pairs disposed between the front substrate and the rear substrate; a plurality of address electrodes disposed between the front and rear substrates, overlapping the sustain electrode pairs; a discharge enhancement layer forming a step in a base region of each discharge cell; and a phosphor layer applied to the inner walls of the discharge cells. Each of the barrier ribs has a roughness that is less than that of the discharge enhancement layer, and this enables a more uniform distribution of the phosphor layer to be achieved.
