Plasma display panel

Abstract

A plasma display panel includes first and second substrates having a predetermined gap therebetween. Barriers are disposed between the first and second substrates to partition discharge cells and fluorescent layers are formed in the discharge cells. Address electrodes corresponding to the discharge cells extend in a first direction, and pairs of first and second electrodes extend in a second direction to cross the first direction. The address electrodes are on one of the substrates to correspond to the discharge cells. A dielectric layer covers the first and second electrodes, wherein the dielectric layer is colored with a first color, the barriers are colored with a second color having a subtractive mixture relation with the first color, and wherein the fluorescent layers include first fluorescent layers on the barriers and the discharge cells, and second fluorescent layers on the first fluorescent layers in the second color.
