Abstract: PROBLEM TO BE SOLVED: To eliminate meandering even in the case of a partitioning wall, having a large height and a narrow width to improve the yield of phosphor application, and prevent brightness nonconformity, by repeating applying, exposing, and developing two or more times through using photosensitive paste containing an inorganic fine particle and a photosensitive organic component to form a two-layer partitioning wall in the center and outer side parts. SOLUTION: The height H1 and width L1 of a center part baking partitioning wall layer, formed by printing, exposing, and developing photosensitive paste, are made 40-150μm and 55μm or less respectively. An outer side part baking partitioning wall is formed so as to have a height H2 of 100-250μm and a width L2 of 15-60μm, by repeating this process, preferably after heat-drying. This strengthens a center part baking partitioning wall to prevent snaking and the fluctuation of the size of line width due to the development. This ratio of the height and width of both the baking partitioning walls is preferably to have a range of 0.2

Abstract: PROBLEM TO BE SOLVED: To enable easy and simple formation of the black screen for plasma displays by specifying the refractive index of the glass powder or the content proportion of the metals or their oxides in the glass powder. SOLUTION: Metals or metal oxides are added to the glass powder in the photosensitive glass paste or applied or coated on the surface of the glass powder thereby forming a black screen pattern. As the metal, are cited Ru, Cr, Fe, Co, Mn, Cu or Ni of which the oxides are black and one or more kinds of metals are preferably employed. The content is 0.5-20wt.% in the glass powder. The refractive index of the glass powder is preferably in the range from 1.5 to 2, because the pattern can be readily formed. When it is used as the screen for plasma display, more than 60wt.% of the inorganic powder is glass powder.

Abstract: PROBLEM TO BE SOLVED: To form a high-accuracy pattern, a bulkhead layer in particular, having good surface flatness and suppressed in thickness dispersion, by applying a photosensitive paste made of glass fine grains and an organic component containing a photosensitive compound on a flexible base material, transferring it onto a glass substrate having an electrode layer formed, and forming a bulkhead by light irradiation, development and backing. SOLUTION: The photosensitive paste containing an organic component containing a photosensitive compound such as a photosensitive monomer such as methyl methacrylate, or its oligomer, or a polymer is applied on a flexible base material such as a polyester film. Glass fine grains of 50-95 pts.wt. and an organic component of 5-50 pts.wt. are contained in the photosensitive paste, and the glass fine grains having the average refraction factor in the range of 1.5-1.7 are selected. A glass substrate having a bulkhead layer obtained by coating, transfer, light irradiation exposure, development, and baking applied on the photosensitive paste can be used on the front face side or the back face side of a plasma display.

Abstract: PURPOSE:To carry out highly fine and high density display by containing glass powder, acrylic copolymer having carboxyl group and ethylene-type unsaturated group in side chains and in the molecular terminals, a photoreactive compounds, and a photopolymerization initiator. CONSTITUTION:A glass powder having glass transition temperature 350-470 deg.C is preferable. An acrylic copolymer having carboxyl group and ethylene-type unsaturated group in the side chains and in the molecular terminals is used as a polymer binder component. The copolymer is produced by adding the ethylene-type unsaturated group to the side chains or molecular terminals of an acrylic copolymer produced by an unsaturated carboxylic acid and an ethylene-type unsaturated compound. As a photoreactive compound to be used, a compound containing photoreactive C-C unsaturated bonds is used. A photopolymerization initiator is preferably added in 0.15-50wt.% of the total of the acrylic copolymer and the photoreactive compound. As a result, a diaphragm can be formed easily and disorder of the width and peripheral parts can be prevented.
