Abstract

A plasma display panel capable of improving a black area ratio and a bright room contrast and reducing a reflected luminance by coloring different layers in the plasma display panel is provided. The plasma display panel includes: a rear substrate; a front substrate colored with a first chromatic color and facing the rear substrate; barrier ribs disposed between the front and rear substrates and defining discharge cells; address electrodes extending in a first direction on the rear substrate and corresponding to the discharge cells; phosphor layers disposed in the discharge cells, wherein at least one of the phosphor layers is colored with a second chromatic color; display electrodes extending in a second direction crossing the first direction on the front substrate and corresponding to the discharge cells; and a front dielectric layer disposed on the front substrate to cover the display electrodes and colored with a third chromatic color.

Claims
