Abstract: PROBLEM TO BE SOLVED: To prevent display defect and improve yield of a display by applying barrier-rib correction paste to a defective part of a barrier rib before a baking process of the barrier rib of a discharge-type display member, and baking it to correct the defective part. SOLUTION: For correcting a defective part before a baking process of a barrier rib, correction paste is applied to the defective part in the barrier rib, they are molded and baked simultaneously together with the barrier rib. Baking after the correction of the defective part prevents the defective part from rising during the baking and height of the defective part is equalized after the correction. This prevents defective display during lighting of a display unit. A paste applying method to the defective part is not especially limited. A method of using an application needle is adequate for applying paste with high viscosity, and a method of using a dispenser has high application speed and is adequate for correcting a large defective part. In either case of the application needle or the dispenser, normally, are having width of an application pattern of 10-50 μm is used.

Abstract: PROBLEM TO BE SOLVED: To provide a phosphor paste which does not cause clogging of filter in the filtration step. SOLUTION: The phosphor paste comprises a phosphor powder, a binder resin, and an organic solvent, and has a property of passing through a 25 mmϕ, 500 mesh filter in the range of 5-80 g/min, and a method for manufacturing a display panel member uses the phosphor paste.

Abstract: PROBLEM TO BE SOLVED: To perform effective correction without deteriorating the shape of previously formed barrier ribs by applying a barrier rib correcting paste containing glass powder, having a softening point which is lower than that of glass powder contained in barrier rib forming paste to a defective part on the barrier rib during a manufacturing process and thereafter baking it. SOLUTION: Barrier rib correcting paste mainly comprises components such as an inorganic powder, an organic binder and a solvent, glass powder containing silicon oxide and/or boron oxide are used as an inorganic component, and its softening point is preferably set 10-100 deg.C lower than that of glass powder in barrier rib forming paste. In order to control the constriction rate in the height direction during baking to 5% or less, 1-50 wt.% of at least one kind of titania, alumina, silica, barium titanate and zirconia is preferably contained as a filler component. The repair of a defective part is performed at 550 deg.C or lower by spot-baking of a paste application part by means of a laser beam having a wavelength which is not in the absorption band of a board.
