MANUFACTURING METHOD OF PLASMA DISPLAY PANEL

摘要

PROBLEM TO BE SOLVED: To realize a prolonged service life of a display function by raising an anti-sputtering property of an inner wall which contacts electric discharge gas. SOLUTION: In the manufacturing method of the plasma display panel which has a covered layer insulating discharge gas against an electrode for main discharge and of which at least the surface contacting the above discharge gas of the above covered layer is a magnesium oxide film of a thickness of 1μm or less, a vapor deposition of the above magnesium oxide film is done on a base plate on which a main discharge electrode is formed under conditions of a base plate temperature of 250 to 350°C and a vapor deposition pressure of 5×10-6to 5×10-5Torr and thus a magnesium oxide film is formed of which an average optical refractive index of a direction of the thickness which represents a film density shall be 1.7 or more against light of a wavelength of 500 nm.
