Abstract:
1. A plasma display panel (PDP), comprising: an upper substrate; an upper dielectric layer arranged on the upper substrate; a lower substrate facing the upper substrate; a lower dielectric layer arranged on the lower substrate and facing the upper dielectric layer; a plurality of barrier ribs arranged between the upper substrate and the lower substrate, the plurality of barrier ribs defining the plurality of discharge cells, the plurality of barrier ribs including a plurality of first barrier ribs and a plurality of second barrier ribs, each of the plurality of second barrier ribs extending in a direction that crosses ones of the plurality of first barrier ribs, each of the second barrier ribs includes sidewall portions and a top portion, each sidewall portion facing into ones of the plurality of discharge cells, each top portion facing the upper substrate and adapted to reflect external light; a plurality of main phosphor layers adapted to produce red, green, and blue light and being arranged within the discharge cells; and a plurality of dummy phosphor layers at least partially connected to the main phosphor layers by connector phosphor layers, the dummy phosphor layers and the connector phosphor layers being adapted to reduce an amount of external light reflected off the top portions of the second barrier ribs, a reflectance of the main phosphor layers, the dummy phosphor layers, and the connector phosphor layers is less than a reflectance of the barrier ribs.
