  • Publication number: 20130017751
    Abstract: It is a method for manufacturing a plasma display panel having a discharge space, and a protective layer opposed to the discharge space. A gas containing a reducing organic gas is introduced into the discharge space, and the protective layer is exposed to the reducing organic gas. Then, the reducing organic gas is emitted from the discharge space. Then, a discharge gas is enclosed in the discharge space. The protective layer contains at least a first metal oxide and a second metal oxide. Furthermore, the protective layer has at least one peak in an X-ray diffraction analysis. The peak exists between a first peak of the first metal oxide in the X-ray diffraction analysis, and a second peak of the second metal oxide in the X-ray analysis. The first peak and the second peak show the same surface orientation as a surface orientation shown by the peak.

  • Publication number: 20130012095
    Abstract: By introducing a gas containing a reducing organic gas into the discharge space, the protective layer is exposed to the reducing organic gas. Then, the reducing organic gas is exhausted from the discharge space. Then, a discharge gas is enclosed to the discharge space. The protective layer includes a nano particle layer formed by nano crystal particles of metal oxides containing at least a first metal oxide and a second metal oxide. Moreover, the nano particle layer has at least one peak in an X-ray diffraction analysis. The peak is located between a first peak in the X-ray diffraction analysis of the first metal oxide and a second peak in the X-ray diffraction analysis of the second metal oxide. The first peak and the second peal have the same plane orientation as the plane orientation indicated by the peak.

  • Publication number: 20130012096
    Abstract: By introducing a gas containing a reducing organic gas into the discharge space, the protective layer is exposed to the reducing organic gas. Then, the reducing organic gas is exhausted from the discharge space. Then, a discharge gas is enclosed to the discharge space. The protective layer includes a base film made of magnesium oxide, and a plurality of metal oxide particles dispersed over the base film. The metal oxide particle includes at least a first metal oxide and a second metal oxide. Moreover, the metal oxide particle has at least one peak in an X-ray diffraction analysis. The peak is located between a first peak in the X-ray diffraction analysis of the first metal oxide and a second peak in the X-ray diffraction analysis of the second metal oxide. The first peak and the second peal have the same plane orientation as the plane orientation indicated by the peak.

  • Patent number: 8283864
    Abstract: A plasma display panel has a front plate, and a rear plate arranged so as to be opposed to the front plate. The front plate has a display electrode, a dielectric layer to cover the display electrode, and a protective layer to cover the dielectric layer. The protective layer has a luminescence peak in a wavelength ranging from not less than 350 nm to not more than 550 nm under irradiation of light having a wavelength of 146 nm. In addition, the protective layer has a luminescence peak in a wavelength ranging from not less than 350 nm to not more than 550 nm under irradiation of light having a wavelength of 173 nm. A ratio A/B between a peak intensity of luminescence under the light having the wavelength of 146 nm and a peak intensity of luminescence under the light having the wavelength of 173 nm falls within a range from more than 3.0 to not more than 7.0.

  • Publication number: 20120064795
    Abstract: Disclosed is a method of manufacturing a plasma display panel having a discharge space and a protection layer facing the discharge space. The protection layer is exposed to the reducing organic gas by introducing gases containing the reducing organic gas into the discharge space. Then, the reducing organic gas is exhausted from the discharge space. Then, the discharge gas is hermetically enclosed in the discharge space.
