A Plasma Display Panel (PDP) in which a dummy area is arranged so as to retain phosphor paste ejected from extra nozzles when a plurality of nozzles are used to apply phosphor paste. The PDP includes a first substrate and a second substrate opposing each other; address electrodes arranged on the first substrate; display electrodes arranged on the second substrate perpendicular to a direction of the address electrodes; barrier ribs arranged in a space between the first substrate and the second substrate to define a plurality of discharge cells; and phosphor layers arranged in each of the discharge cells; wherein a display area comprises a plurality of the discharge cells arranged at positions where the address electrodes and the display electrodes cross each other; wherein a non-display area is arranged adjacent to an edge of the display area along a direction perpendicular to a direction in which phosphor layers of the same color are applied to discharge cells neighboring each other; and wherein the phosphor layers are arranged in portions of the non-display area.

Plasma display panel with dielectric layer extending in non-display area

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 Rof curvature at the corner satisfies the following condition: 0.05a=R=0.2a, where a is a width of the protrusion portion measured in the extending direction of the line portion.

Plasma display panel (PDP)

A manufacturing method of a plasma display panel is to form a transparent electrode pattern on a boundary portion between a display region and a non-display region when the transparent electrode pattern is formed by the laser ablation method. The method includes depositing a transparent electrode material layer on a first substrate, patterning the transparent electrode material layer in a display region to form a transparent electrode pattern in the display region, patterning the transparent electrode material layer in a boundary portion to form a transparent electrode pattern in the boundary portion arranged between the display region and a non-display region, depositing a metal conductive layer on the transparent electrode pattern in the display region, patterning the metal conductive layer to form a bus electrode, forming an address electrode and a barrier rib on a second substrate, and aligning and assembling a first plate that includes the first substrate to a second plate that includes the second substrate so that the address electrode and the barrier rib each intersect each of the bus electrode and the transparent electrode pattern in the display region.
