Patent ID: 7218043

Claim:
A plasma display panel comprising: a lower substrate and an upper substrate, which are spaced apart by a predetermined distance from each other to define a plurality of discharge cells therebetween; a plurality of barrier ribs disposed between the lower substrate and the upper substrate; a plurality of address electrodes formed in parallel with one another on an upper surface of the lower substrate; a plurality of discharge electrodes formed in a direction crossing the address electrodes on a lower surface of the upper substrate; and a fluorescent layer formed on an inner wall of the discharge cells, wherein the upper substrate comprises a plurality of light guides, which are formed corresponding to said plurality of address electrodes or said plurality of discharge cells, the light guides having a light incident surface, which is larger in area than a light emitting surface thereof, the light guides having an internal surface for internally reflecting light to focus and output visible light generated from the discharge cells out of the light emitting surface.
