The present disclosure is a plasma display panel including a green phosphor layer. In this plasma display panel, the green phosphor layer includes a phosphor represented by a general formula: aYO3/2.(3−a)CeO3/2.bAlO3/2.cGaO3/2, where 2.80≦̸a≦̸2.99, 1.00≦̸b≦̸5.00, 0≦̸c≦̸4.00, and 4.00≦̸b+c≦̸5.00 are satisfied. In this phosphor, a peak whose peak top is located in a range of diffraction angle 2&thetas; of not less than 16.7 degrees but not more than 16.9 degrees is present in an X-ray diffraction pattern obtained by measurement on the phosphor using an X-ray with a wavelength of 0.774 Å. The green phosphor layer also includes a phosphor represented by a general formula: dZnO.(2−d)MnO.eSiO2, where 1.80≦̸d≦̸1.90 and 1.00≦̸e≦̸1.02 are satisfied, in an amount of 30 wt % or more and 80 wt % or less of the total weight of green phosphors.
