Abstract:
A forming method of a protective film made of oxide containing any one of calcium oxide (CaO), strontium oxide (SrO) and barium oxide (BaO) and having a higher band gap than that of magnesium oxide (MgO) (higher than 7.9 eV) is provided. By adjusting a time constant of a protective film to a predetermined value or larger, the voltage drop time is adjusted so as to be usable for a plasma display panel. At this time, the time constant τ(=C×R) defined by the discharge capacitance C and the protective film resistance R is referenced.
