A PDP that can maintain favorable color balance is provided. In the PDP which is equipped with back phosphor layers of the three colors red, green, and blue in a back panel, front phosphor layers are provided in a front panel respectively in opposition to back phosphor layers other than the back phosphor layer whose luminance degrades fastest with time among the red, green, and blue back phosphor layers. These front phosphor layers are prone to luminance deterioration caused by ultraviolet radiation or ion bombardment, and therefore accelerate the luminance degradation speeds of their opposite back phosphor layers. Accordingly, the luminance of light emitted from each of the two combinations of the front and back phosphor layers is brought to be more balanced with the luminance of light emitted from the back phosphor layer with the highest luminance degradation speed. Hence the PDP can maintain favorable color balance over a long time.
