Abstract
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.
