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.

A protective layer of a plasma display panel includes smoky magnesium oxide, the smoky magnesium oxide having single crystal magnesium oxide with a plurality of cavities therein.

Protective layer and plasma display panel including the same

A Plasma Display Panel (PDP) includes a dielectric layer having a plurality of dielectric-layer perforated holes arranged in a matrix; and upper and lower electrode layers having electrode-layer perforated holes connected to the dielectric-layer perforated holes and arranged on both surfaces of the dielectric layer; the upper electrode layer includes a plurality of first electrodes extending in a first direction, the plurality of first electrodes surrounding a group of electrode-layer perforated holes arranged in the first direction; and the lower electrode layer includes a plurality of second electrodes extending in a second direction different from the first direction, the plurality of second electrodes surrounding a group of electrode-layer perforated holes arranged in the second direction. Individual electrodes surrounding the electrode-layer perforated holes protrude from the dielectric layer toward the centers of the perforated holes such that a facing discharge is generated between the upper and lower individual electrodes, resulting in a PDP having stable characteristics and high efficiency and having a simple structure.

Micro discharge (MD) plasma display panel including electrode layer directly laminated between upper and lower subtrates

Provided are a protective layer made of magnesium oxide containing at least one rare earth element selected from the group consisting of the rare earth elements, in which the content of the at least one rare earth element is from about 5.0&#xd7;10to about 6.0&#xd7;10per 1 part by weight of the magnesium oxide, a composite for forming the protective layer, a method of forming the protective layer, and a plasma display panel including the protective layer. The protective layer can reduce a discharge delay time and the temperature dependency of the discharge delay time, and thus, is suitable for single scan and an increase in Xe content.
