A plasma display panel includes a first substrate and a second substrate facing each other to provide a discharge space between the first substrate and the second substrate, a scan electrode and a sustain electrode both provided on the first substrate, a dielectric layer for covering the scan electrode and the sustain electrode, and a protective layer provided on the dielectric layer. The protective layer includes magnesium oxide, magnesium carbide, and silicon. This plasma display panel performs stable discharge characteristics, such as a driving voltage, thereby displaying an image stably.
