Abstract: PROBLEM TO BE SOLVED: To restrict pouring mark after pouring fluorescent slurry by specifying a composition. SOLUTION: A preprocessing composition is made of powder, polyvinyl alcohol, ammonium dichromate, surfactant, and water. Specifically, zinc sulfide is used for the powder, and weight percentages of the ingredients are, in the order of the above enumeration, 25%, 2.5%, 0.1%, and 0.2%, is weight and the remainder, and the mixture is uniformly mixed. The obtained slurry is extended over a panel of a CRT, developed, and dried. When fluorescent material slurry is poured, dripped, and dried, and when the formed coating surface is visually observed, improvement up to a favorable level is recognized in that almost no pouring mark is found.

Abstract: PROBLEM TO BE SOLVED: To obtain a high picture quality improved even in the stripe edge, by fixing a panel, scanning a developer nozzle in the direction of a forming surface of a fluorescent screen stripe with a fixed space, so as to obtain a uniform developing time in the center part and the peripheral part. SOLUTION: In the case of manufacturing a carbon stripe and three-color fluorescent material stripe, a fluorescent screen stripe 2 is formed in the direction Y relating to the internal surface of a panel 1, a developer nozzle row 3 arranged in the direction Z relating to the surface of the panel 1 is opposed. The nozzle row 3 is moved in the direction Y by a nozzle row vertical motion mechanism part 4. The fixed panel 1 and the nozzle row 3 opposed in the direction Z with a fixed space are moved in the direction Y, scanning of developer is performed. By controlling this moving speed, a developing time is made uniform, since an injection direction of the developer is in the same direction to the stripe 2, the amount of liquid traversing the stripe 2 is reduced, the stripe edge is improved. Further, even when the picture plane shape is formed laterally long, it can sufficiently correspond.

Abstract: PROBLEM TO BE SOLVED: To prevent that a phosphor slurry, adhering to the skirt part of a cathode-ray tube panel by a total surface exposure in an external surface exposing method, is sensitized to be hardened, and remains, as dusts in a color cathode-ray tube even after development, to deteriorate a characteristic such as the breakdown voltage characteristic of the color cathode-ray. SOLUTION: A total surface exposure is performed in a condition where the skirt part 8 of a cathode-ray tube panel 6 is shaded. For this purpose, a total surface exposure device is used, which has a shading plate 3 for shading light to the skirt part 8 of a set cathode-ray tube panel 6, and a shade body moving mechanism 5 for relatively moving the plate 3 to the panel 6 along the vertical direction of the panel 6.

Abstract: PURPOSE: To prevent the generation of unevenness of color by discharging the curing agent from a discharging nozzle in nearly parallel with the inner surface of a panel. CONSTITUTION: A discharging nozzle 10 as a curing agent coating device is formed into the L-shape, and the curing agent is discharged in nearly parallel with the inner surface of a panel 8. The inner diameter of the discharging nozzle 10 is set at the predetermined size width than that of the conventional one. Consequently, when the tannic acid solution as the curing agent is supplied through a hose 12 connected to the nozzle 10, the tannic acid solution is discharged from the tip of the nozzle 10 in nearly parallel with the inner surface of the panel 8. The tannic acid solution discharged from the nozzle 10 is jetted in parallel, and dropped by the self-weight, but it is dispersed in the process, and width of the curing agent at the time when the curing agent is adhered to the inner surface of the panel, namely, the initial adhesion width is widened. Consequently, the initial adhesion area is widened to 80-300cm , and unevenness of the hardening speed is reduced.

Abstract: PROBLEM TO BE SOLVED: To provide a liquid crystal display device capable of suppressing the occurrence of luminance unevenness, even if the device is influenced by the humidity or the temperature.
SOLUTION: The liquid crystal device is equipped with a light source that irradiates light, a light guide plate diffusing the light from the light source; and a reflecting material disposed on the back face of the light guide plate and reflecting the light diffused by the liquid guide plate, and is provided with a gap-holding member on at least one of the light guide plate and the reflecting material, the member preventing adhesion between the light guide plate and the reflecting material. As a result, adhesion between a reflecting sheet and the light guide plate can be prevented, the occurrence of luminance unevenness is suppressed, even if the device is influenced by the humidity or the temperature.

Abstract: PROBLEM TO BE SOLVED: To restrain the influence of a defect such as faulty etching or deformation in a color selecting mechanism to the utmost even when the defect occurs in the color selecting mechanism in the case of radiating ultraviolet rays to the inner surface of a face panel through the color selecting mechanism in the fluorescent surface manufacturing stage of a cathode ray tube. SOLUTION: By arranging a shielding plate 15 having an aperture 16 through which the ultraviolet rays are transmitted between the color selecting mechanism 2 and an ultraviolet light source 12 radiating the ultraviolet rays, the sharpness of an irradiation pattern formed on the inner surface of the face panel 1 of the cathode ray tube is adjusted according to the size of the aperture 16 in the case of radiating the ultraviolet rays to the inner surface of the face panel 1 of the cathode ray tube through the color selecting mechanism 2.

Abstract: PROBLEM TO BE SOLVED: To provide a color cathode-ray tube with which a black layer is hardly peeled from the inside surface of a panel in forming a color filter, a pigment is included in the color filter with a sufficient degree of filling, and which has a high display image contrast and also provide its manufacturing method. SOLUTION: In this color cathode-ray tube, a weight ratio of a pigment to a adhesive is 5:1 to 15:1 in its color stripes 14. Because the weight ratio is not more than 15:1, the rate of the pigment is not excessively high and carbon stripes 12 are hardly peeled from the inside surface of a panel 11 in forming color filter stripes 14. In addition, since the weight ratio is not less than 5:1, the rate of the pigment is not excessively low and the pigment is included in the color filter stripes 14 with a sufficient degree of filling.

Abstract: PROBLEM TO BE SOLVED: To prevent separation failure of phosphor stripes formed at a microscopic pitch by correcting an ultraviolet ray irradating position in response to a deformation quantity of panel glass by first and second correcting lens systems when exposed to form carbon stripes and the phosphor stripes. SOLUTION: An aperture grille 6 is installed in a panel part 3. In a photoresist exposing process, ultraviolet rays from an ultraviolet lamp 11 pass through a first correcting lens system 12, and expose a prescribed position of a photoresist applied to an inside surface of a face part 3a through the aperture grille 6, and print the photoresist. In a green phosphor slurry exposing process, an ultraviolet ray irradiating position of the ultraviolet lamp 11 is decided by a second correcting lens system 13, and green phosphor slurry is exposed in a stripe shape to a carbon stripe unformed position. The second correcting lens system 13 is constituted by changing an ultraviolet ray irradiating position correcting lens 12b of the first correcting lens system 12 to a lens 13b corresponding to deformation in heat drying of the panel part 3.
