Protecting layer for use in plasma display panel (PDP), method of forming the protecting layer, and PDP including the protecting layer

A method of forming a protecting layer of a Plasma Display Panel (PDP), the method comprising:

• preparing a substrate;
• forming a predetermined pattern composed of a metal on the substrate;
• and
• forming a layer composed of magnesium oxide to cover the metal having the predetermined pattern;
• wherein forming a layer composed of magnesium oxide arranges the metal having the predetermined pattern to be disposed away from a surface of the protecting layer by 10% or less than the thickness of the protecting layer.

A Plasma Display Panel (PDP), comprising:

• a protecting layer, the protecting layer including:
• a metal;
• and metal oxide;
• wherein the metal is disposed away from a surface of the protecting layer by 10% or less than a thickness of the protecting layer.
