Patent number: 7462989Abstract: A plasma display panel (PDP) includes front plate, scan electrodes and sustain electrodes both formed on front plate, dielectric layer covering scan and sustain electrodes, and protective layer formed on dielectric layer. Protective layer contains silicon (Si) and nitrogen (N), and is made of magnesium oxide (MgO) including Si of which atoms count in the range from 5×1018 pieces/cm3 to 8×1021 pieces/cm3. The foregoing construction allows the PDP to shorten a discharge-delay time, achieve a quick response of discharge to a voltage applied, and suppress changes of the discharge-delay time with respect to a temperature.Type: GrantFiled: May 14, 2004Date of Patent: December 9, 2008Assignee: Panasonic CorporationInventors: Kazuyuki Hasegawa, Yoshinao Oe, Kaname Mizokami, Hirokazu Nakaue, Hiroyuki Kado
