A radio wave absorber includes a base member, and a radio wave absorption film formed on the base member. The radio wave absorption film includes at least MTC-substituted &#x3b5;-FeOand black titanium oxide. The MTC-substituted &#x3b5;-FeOis a crystal belonging to the same space group as an &#x3b5;-FeOcrystal and expressed by &#x3b5;-MTiCoFeOwhere M is at least one element selected from the group consisting of Ga, In, Al, and Rh, 0&#x3c;x&#x3c;1, and 0&#x3c;y&#x3c;1.

Radio wave absorber

A plasma display of this invention includes a front panel, and this front panel includes a substrate, a plurality of display electrode pairs formed in stripes on the substrate, a dielectric layer formed to cover the display electrode pair and the substrate, a dielectric-protective layer formed to cover the dielectric layer, and fine particles containing a crystal of a metal oxide, the fine particles being dispersed on a surface of the dielectric-protective layer. The display electrode pair is provided with a strip-shaped scanning electrode and a strip-shaped sustaining electrode each having a laminate structure of a transparent electrode and a bus electrode. In the surface of the dielectric-protective layer, a first region corresponding to a region facing the bus electrode of the scanning electrode is smaller than a second region corresponding to a region except the first region, with regard to a cover rate of the surface covered with the fine particles. This configuration allows effective increase of a charge accumulation amount in the first region, and also allows suppression of increase of a discharge start voltage.

Plasma display panel and method for manufacturing the same

A plasma display panel has front plate () and back plate () that are faced to each other. The front plate has a display electrode, a dielectric layer, and a protective layer on a front glass substrate, and the back plate has an address electrode, a barrier rib, and a phosphor layer on a back glass substrate. The periphery of the front and back plates is sealed with sealing material () to form discharge space. Sealing material () contains, as a glass component, bismuth oxide and at least one of molybdenum oxide and tungsten oxide.

Plasma display panel

A plasma display panel (PDP) is made of front panel () and rear panel (). The front panel includes display electrodes (), dielectric layer (), and protective layer () that are formed on glass substrate (). The rear panel includes address electrodes (), barrier ribs (), and phosphor layers () that are formed on rear glass substrate (). The front panel and the rear panel are faced with each other, and the peripheries thereof are sealed to form discharge space () therebetween. Primary dielectric layer () is provided to cover address electrodes (), and barrier ribs () are formed on primary dielectric layer (). Primary dielectric layer () is made of dielectric glass containing at least bismuth oxide and having a softening point exceeding 550&#xb0; C.
