A protecting layer is formed of a magnesium oxide and at least one additional component selected from the group consisting of a copper component selected from copper and a copper oxide, a nickel component selected from nickel and a nickel oxide, a cobalt component selected from cobalt and a cobalt oxide, and an iron component selected from iron and an iron oxide; a composite for forming the protecting layer; a method of forming the protecting layer; and a plasma display panel including the protecting layer. The protecting layer, which is used in a PDP, protects an electrode and a dielectric layer from a plasma ion generated by a gaseous mixture of Ne and Xe, or He, Ne, and Xe, and discharge delay time and dependency of the discharge delay time on temperature can be decreased and sputtering resistance can be increased. |
