ABSTRACT:
A Plasma Display Panel (PDP), in which the precision level in shaping the display electrodes is improved by changing the shape of the transparent electrode, includes: address electrodes formed on a first substrate, barrier ribs defining discharge cells in a space between the first substrate and a second substrate and display electrodes, formed on the second substrate in a direction crossing the address electrodes, including a pair of line portions arranged on both sides of each discharge cell and having a pair of protrusion portions, facing each other, extending from the respective line portions toward the center of each discharge cell. The pair of the protrusion portions has rounded contours at both corners of each protrusion portion facing the paired protrusion portion and its radius R1of curvature at the corner satisfies the following condition: 0.05a=R1=0.2a, where a is a width of the protrusion portion measured in the extending direction of the line portion.
