    摘要： A dispersion liquid composition for a black matrix, which includes a solvent, and at least one of light absorption material having an average particle diameter ranging from 10 to 500 nm and selected from the group consisting of manganese oxide and a solid solution containing manganese oxide and ferric oxide. It is possible, with the employment of this dispersion liquid composition, to form a light absorption layer which is capable of reducing the diffuse reflection factor as well as the mirror reflectivity thereof, thereby making it possible to obtain a display screen improved in properties as a black matrix.

    摘要： A method of manufacturing a display screen provided with a filter pattern comprising a first pigment pattern and a second pigment pattern, which comprises the steps of, forming a first pigment layer by coating a solution containing a first pigment on a surface of a substrate and drying the resultant coated layer, forming a first pigment pattern by subjecting the first pigment layer to a patterned light exposure and developing the resultant exposed pattern, forming a second pigment layer by coating a solution containing a second pigment on the surface of the substrate including a surface of the first pigment pattern, and forming a second pigment pattern by selectively removing, through rinsing, a portion of the second pigment layer which is disposed on the first pigment pattern. At least either one of the solution containing a first pigment and the solution containing a second pigment contains an adhesion regulating agent so as to cause the adhesion strength between the first pigment pattern and the second pigment layer to become lower than the adhesion strength between the substrate and the second pigment layer, thus allowing a portion of the second pigment layer formed on the first pigment pattern to be selectively removed.

    摘要： A color picture tube comprising an envelope including a front panel, a phosphor screen formed in the inner surface of the front panel, and an electron gun arranged in the envelope. The phosphor screen includes a light absorbing layer having a plurality of holes and phosphor layers formed in the holes so as to partially overlap the light absorbing layer. The transmittance T of the light absorbing layer, the ratio a of the area of a light emitting region in a portion where the light absorbing layer overlaps the phosphor layers to the area of the phosphor screen, the ratio b of the area of the light absorbing layer to the area of the phosphor screen, and the ratio r of the light emitting region in the holes to the area of the holes satisfy the following relational expression: 1/T.gtoreq.1/2{(rb/a)-[a/(1-b)r]}.

    摘要： A color cathode ray tube includes an envelope having, a faceplate, light filtering device provided on an outer surface of the faceplate, and a phosphor screen formed on an inner surface of the faceplate. The phosphor screen is composed of red, blue, and green emitting phosphors. The red emitting phosphor is primarily a Y.sub.2 O.sub.3 :Eu phosphor with an Eu activation amount between 3.0 mol % and 9.0 mol % inclusive with respect to a Y.sub.2 O.sub.3 amount as a base material. The light filtering device is provided in front of the faceplate for selectively transmitting light having a maximum absorption wavelength of 575.+-.20 nm in a wavelength range from 400 nm to 650 nm, and satisfies the following relationship: T.sub.min .ltoreq.T.sub.550 .ltoreq.T.sub.530, 1.ltoreq.T.sub.450 /T.sub.530 .ltoreq.2, 1.ltoreq.T.sub.615 /T.sub.530 .ltoreq.2, 0.7.ltoreq.T.sub.450 /T.sub.615 .ltoreq.1.43, T.sub.615 /T.sub.580-600 .gtoreq.1.1, wherein T.sub.450, T.sub.530, T.sub.505, T.sub.615, T.sub.min and T.sub.580-600 represent the transmissivities for lights of wavelength of 450 nm, 530 nm, 550 nm, 615 nm, the maximum absorption wavelength of 575.+-.20 nm and a maximum absorption wavelength in a wavelength range of 580 nm to 600 nm, respectively.

    摘要： There is disclosed a salt of a polymer having charged anionic functionalities used as a dispersant in a dispersion solution containing a pigment and used for forming a first pigment layer. A substance which forms a salt with a polymer having charged anionic functionalities is mixed into a solution applied on the pigment layer, and/or mixed into a developing solution. The formed layers are patterned and thus a display screen is obtained.
