Plasma display panel and plasma display apparatus

A plasma display panel and a plasma display apparatus are disclosed. The plasma display panel includes a front substrate including a scan electrode and a sustain electrode positioned parallel to each other, an upper dielectric layer positioned on the scan and sustain electrodes, a rear substrate on which an address electrode is positioned to intersect the scan and sustain electrodes, a lower dielectric layer positioned on the address electrode, a barrier rib positioned between the front substrate and the rear substrate to partition a discharge cell, and a phosphor layer positioned inside the discharge cell. The upper dielectric layer includes a glass-based material and a blue pigment. The phosphor layer includes a phosphor material and MgO material.
