Abstract
Disclosed is a plasma display panel. The plasma display panel comprises 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 in parallel with the plurality of address electrodes to focus and output visible light generated from the discharge cells by a discharge, the light guides having a light incident surface.
