A plasma display panel demonstrating excellent image display performance by suppressing generation of initialization bright points through modification of the phosphor layer, and by eliminating variation in discharge characteristics between the discharge cells of each color. In addition to solving these problems, the luminance of the plasma display panel is also enhanced by using the ultraviolet rays emitted in the discharge space in order to promote the production of visible light on the front panel side. Specifically, the phosphor layer (14) is composed of a phosphor component and of MgO powder (16) disposed principally inside the phosphor layer and exposed towards the surface (140) facing the discharge space in order to impart secondary electron emission characteristics. The MgO powder (16) is composed of MgO particles (16a-16d) having a crystal structure with two specific crystal faces consisting of the (100) crystal face and the (111) crystal face, or three specific crystal faces consisting of the (100) crystal face, the (110) crystal face, and the (111) crystal face.
