A full color three electrode surface discharge type plasma display device that has fine image elements and is large and has a bright display. The three primary color luminescent areas are arranged in the extending direction of the display electrode pairs in a successive manner and an image element is composed by the three unit luminescent areas defined by these three luminescent areas and address electrodes intersecting these three luminescent areas. Further, phosphors are coated not only on a substrate but also on the side walls of the barriers and on address electrodes. The manufacturing processes and operation methods of the above constructions are also disclosed.

Full color surface discharge type plasma display device

A display panel is provided that has a multilayer structure made of a colored glass layer having a desired shape and optical characteristics and a non-colored glass layer having high transparency, as well as high productivity. The display panel has a non-colored glass layer and a colored glass layer contacting the non-colored glass layer. A multilayer structure is formed that includes a colored paste layer and a non-colored paste layer. In the colored paste layer, crystallization glass powder that is crystallized at the temperature TA and coloring agent are diffused. In the non-colored paste layer, glass powder whose softening point is the temperature TB that is higher than the temperature TA. The multilayer structure is heated to the temperature TC that is higher than the temperature TB and is lower than the softening point of the crystallization glass powder after the crystallization to be burned, so that the non-colored glass layer and the colored glass layer are formed simultaneously.

Gas-discharge display panel and process for manufacturing the display panel

A plasma display panel includes a dielectric layer in which a filler for enhancing reflectance is dispersed. To increase luminescence efficiency, the filler consists of flakes oriented in parallel to the surface of the dielectric layer.

The present invention relates to a plasma display panel comprising transparent electrodes and a dielectric layer covering said transparent electrodes on at least one substrate of a pair of substrates facing each other with a discharge space therebetween, the main constituent of the transparent electrodes is included in the dielectric layer. Further, the main constituent of the transparent electrode is indium oxide and indium oxide is included in the dielectric layer. By including the main constituent of the transparent electrodes in the dielectric layer, it is believed that the drop in conductivity caused by diffusion of the dielectric substance in the transparent electrodes during high-temperature processing is prevented.

Glass paste composition for forming dielectric layer on electrodes of plasma display panel

A plasma display panel assembly includes electrodes and a dielectric layer covering the electrodes. The dielectric layer is formed of a low-melting-point glass, and the electrodes are formed of a metal containing a crystallized glass. The metal and the low-melting-point glass are simultaneously fired to complete the electrodes and the dielectric layer. Thus, in a manufacturing process of an AC plasma display panel, the number of firing steps can be reduced.

Local losses of material of transparent electrodes, in a plasma display panel including transparent electrodes, bus electrodes and, a dielectric layer covering these electrodes, are prevented by using a plasma display panel according to the present invention. The plasma display panel is formed on at least one substrate of a pair of substrates provided opposite each other via a discharge space. An element, which is a main element of the bus electrode composition, is included in the composition of the dielectric layer. Since the main element of the bus electrode is included in the dielectric layer, local losses of the transparent electrode can be prevented even through the high temperature baking process of the dielectric layer. A preferred choice as the main element of the bus electrode composition is copper, but other elements are also suitable and will perform acceptably.
