PROBLEM TO BE SOLVED: To provide a plasma display panel capable of increasing a luminance maintenance factor with raised color temperature. SOLUTION: This plasma display panel is provided with barrier ribs for limiting red, green and blue sub-pixels 114R, 114G and 114B formed between an upper substrate and a lower substrate and having red, green and blue phosphor layers formed therein, respectively; and upper discharge electrodes 131 and lower discharge electrodes 132, arranged so as to respectively correspond to the sub-pixels. In the plasma display panel, each unit pixel is provided with a total of four sub-pixels by further providing another sub-pixel 114B', having the same color as that of the sub-pixel having a color that is lowest in the maximum emission luminance out of the red, green and blue sub-pixels and by providing phosphor layers, having different luminance and life characteristics for two sub-pixels 114B and 114B' that have colors lowest in the highest emission luminance.
