Abstract:
1. A plasma display panel comprising: a front substrate; a rear substrate facing the front substrate; a barrier rib that is positioned between the front substrate and the rear substrate and partitions a discharge cell; and a phosphor layer formed on the discharge cell, the phosphor layer including a first phosphor layer having a first pigment configured to emit red light, a second phosphor layer having a second pigment configured to emit blue light, and a third phosphor layer configured to emit green light, wherein a thickness of the second phosphor layer is larger than a thickness of the first phosphor layer, wherein the first phosphor layer is configured such that, when a content of the first pigment is 0.5 part by weight, a reflectance is equal to or less than about 50% at a wavelength of 400 nm to 550 nm measured when the front substrate is removed.
