Abstract
A plasma display panel is disclosed. The plasma display panel includes 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 inside the discharge cell. The phosphor layer includes a first phosphor layer emitting first color light, a second phosphor layer emitting second color light, and a third phosphor layer emitting third color light. The first phosphor layer includes a first pigment. A thickness of the second phosphor layer is larger than a thickness of the first phosphor layer.

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.
