Abstract
A plasma display panel and a plasma display apparatus are disclosed. The plasma display panel includes a front substrate, a rear substrate positioned to be opposite to the front substrate, 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 phosphor layer includes a first phosphor layer emitting red light, a second phosphor layer emitting blue light, and a third phosphor layer emitting green light. The first phosphor layer includes a red pigment. At least one of the first phosphor layer, the second phosphor layer or the third phosphor layer includes magnesium oxide (MgO) material.
