The present invention includes a method of producing a planar display device by application of the method. The fine partition walls are formed on the surface of a second substrate that constitutes a second panel by jet processing using an abrasive comprised of a powder of calcium carbonate coated with silicone on the surfaces thereof. Each of the particles constituting the abrasive has a three-dimensional shape comprised of a stack of different-sized triangular or more-angular polygonal layers. The maximum particle diameter of the abrasive is not more than &#xbd; times the width of the fine partition walls, and the mean particle diameter of the abrasive is not more than &#x2155; times the width of the fine partition walls.

Method of forming fine partition walls, method of producing planar display device, and abrasive for jet processing

A plasma display device disclosed herein is capable of enhancing the contrast of external light, facilitating application of phosphor paste on the bottom of each space surrounded by lattice-like barrier ribs, and reducing a variation in the amount of the phosphor paste applied as much as possible. The lattice-like barrier ribs include lateral ribs extending along a first direction while being nearly in parallel to each other, and vertical ribs extending along a second direction different from the first direction while being nearly in parallel to each other. Each of the lateral ribs is composed of two or more rows of rib elements. Notches for communicating spaces surrounded by the vertical ribs and the lateral ribs to each other in the first direction and/or the second direction are formed at least in portions of the vertical ribs and/or the lateral ribs.

Plasma display device having barrier ribs

A method of forming fine partition walls by which fine partition walls with stable shape can be formed with good processing accuracy and at good grinding efficiency by a jet processing technique, a method of producing a planar display device by application of the method, and an abrasive for jet processing to be used in these methods, are disclosed. The fine partition walls are formed on the surface of a substrate by jet processing using an abrasive comprised of a powder of calcium carbonate coated with silicone on the surfaces thereof. Each of the particles constituting the abrasive has a three-dimensional shape comprised of a stack of different-sized triangular or more-angular polygonal layers.

Alternating current driven type plasma display device and method for production thereof

This invention relates to a method for manufacturing a flat display panel device suitable for being applied to a plasma display panel and the like. In the method comprising forming a barrier-ridge-forming layer over a whole surface of a substrate having an electrode pattern, then removing from barrier-ridge-forming layer the unnecessary portions by jetting an abrasive, so as to form a barrier ridge, and further filling the removed portions with fluorescent paste layer and removing from fluorescent paste layer the unnecessary portions by jetting the abrasive until a given discharge space can be kept. Organic material particles coated with an inorganic material are used as the abrasive for removing the barrier-ridge-forming layer and/or the fluorescent paste layer. By coating the organic material with the inorganic material, the abrasive particles become roundish. Thus, even if these are used as the abrasive, it is not feared that they injury the surfaces of the glass substrate and the address electrode.
