Abstract
Provided are a protecting layer for a plasma display panel (PDP), a method of forming the same, and a PDP including the protecting layer. The protecting layer includes a magnesium oxide-containing layer having a surface to which magnesium oxide-containing particles having a magnesium vacancy-impurity center (VIC) are attached. The protecting layer is resistant to plasma ions and has excellent electron emission effects, and thus, a PDP including the protecting layer can be operated at low voltage with high discharge efficiency.
