A plasma display panel for improving a color coordinates correction and a
color temperature is disclosed. In the plasma display panel, a vertical
barrier rib separates red, green and blue discharge cells from each other
in a longitudinal direction. A horizontal barrier rib is provided between
the vertical barrier ribs to separate the red, green and blue discharge
cells from each other in a wide direction. The horizontal barrier rib has
a first horizontal barrier rib provided between the red discharge cells,
a second horizontal barrier rib provided between the green discharge
cells, and a third horizontal barrier rib provided between the blue
discharge cells and having a smaller width than the first and second
horizontal barrier ribs.
