Plasma display panel having dielectric layer with specific color additive

Abstract

A plasma display panel is able to contrast thereof by increasing a color temperature of the plasma display panel, which comprises a dielectric layer controlling a light transmittance for visible light of a certain wavelength emitted from a phosphor in the plasma display panel.
