処理方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for processing glass spacers used in flat display devices such as liquid crystal display panels and plasma display panels.

行われている。[Prior art and its problems] In flat display devices such as liquid crystal display panels and plasma display panels, it is necessary to maintain a constant distance between a pair of glass substrates each equipped with an electrode. The gap between the glass substrates is maintained at a constant distance by uniformly dispersing them as spacers on the glass substrates and sandwiching them between the two glass substrates.

画像が白化してコントラストが低下するという問題があ
った。However, glass fibers and glass beads that are generally used as spacers are transparent, and when displayed on a flat display device, there is a problem in that the image in the dark area where the spacer is located becomes white and the contrast is reduced.

のが実情である。In recent years, due to the above-mentioned circumstances, it has been proposed to produce black or blue colored glass molded bodies by incorporating coloring components such as trivalent chromium, manganese, or cobalt into glass, and to use them as spacers for flat display devices. Even if the glass is colored by this method, the degree of coloring will be slight if it is formed into a small spacer shape, such as a fiber shape with a length of 1 to 200μ and a diameter of I to 25μ, or a bead shape with a diameter of 25 to 800μ. In some cases, the image becomes almost colorless, and the actual situation is that the effect of preventing whitening of the image is small.
