摘要： A method for forming a phosphor screen comprising the step of forming a phosphor layer containing a thermoplastic resin on the inner surface of a face plate, the step of pressurizing the phosphor layer being heated to plasticate the thermoplastic resin and smooth the surface of the phosphor layer, and the step of forming a metal film on the surface-smoothed phosphor layer and heating the face plate. Thermoplastic resin having a softening temperature of 50–350° C. can be used in the phosphor layer, and 0.05–50 wt % of such a thermoplastic resin in solid content ratio is contained in the layer. Heating/pressurizing conditions preferably involve temperatures of 50–350° C. and pressures of 10–10000 N/cm2. This method enhances the film forming property of a metal back layer and prevents cracks and pinholes in the metal back layer.

摘要： This dispersion liquid composition for black matrix comprises; manganese oxide having an average particle diameter in the range of 50 to 2000 nm, or solid solution of manganese oxide and ferric oxide having an average particle diameter in the range of 50 to 2000 nm and a manganese content in the range of 15 to 70% by weight; at least one kind of dispersing agent selected from a group of water-soluble acrylic resin, sodium salt, ammonium salt or potassium salt of water-soluble acrylic resin, and sodium salt, ammonium salt or potassium salt of polycarboxylic acid or ligninsulfonic acid or bisphenolsulfonic acid; and water, or a solvent mixture of water and an organic solvent compatible with water. By employing such a dispersion liquid composition for black matrix, light reflectivity of a light absorption layer of an interface with a panel is remarkably reduced. Accordingly, in a display device such as a color cathode ray tube, a display surface in which superposition of ambient light is difficult to occur is realized.

摘要： An image display unit having a structure in which a heat-resisting fine particle layer is formed on a metal back layer disposed on a phosphor layer, and a getter layer is deposited/formed on the heat-resisting fine particle layer by vapor-depositing. The fine particle layer is desirably formed in a specified pattern, and a filmy getter layer is formed in a pattern complementary to the former pattern. The average particle size of heat-resisting fine particles which may use SiO2, TiO2, Al2O3, Fe2O3 is 5 nm to 30 μm. Since abnormal discharging is restricted, the destruction and deterioration of an electron emitting element and a phosphor screen are prevented to provide a high-brightness, high-grade display.

摘要： A metal back-attached phosphor screen includes a light absorption layer (2) and a phosphor layer (3) on an inner surface of a face plate (1) respectively, and a metal back layer (5) formed on the phosphor layer (3). The light absorption layer (2) contains an oxygen carrier prepared by adding a reducing metal to a metal oxide. A particle size of the oxygen carrier can be set to be 1 to 10 μm. Besides, a phosphor material in which an activator such as Eu is added to a phosphor host material including oxygen such as Y2O2S, can be used as the oxygen carrier. In an image display device such as an FED, it is possible to eliminate a generation and an emission of a gas from the phosphor screen, and to improve an operation life of an electron emitting source.
