Abstract: PURPOSE: To enable a filter to be manufactured by applying pigment particles and a high molecular salt solution on a base plate and drying it, exposing it into the specified pattern, and developing it by using an alkaline aqueous solution. CONSTITUTION: A light absorbing layer 12 having the specified pattern is formed as a black matrix on a base plate made of glass, for example, on the inner surface of a panel 10 of a color cathode-ray tube. This layer 12 is made of graphite formed by the conventional method. The pigment dispersion liquids for forming blue, green and red filters is prepared. These dispersion liquids contain pigment particles and high molecular electrolytic salt solutions (containing photoresists). The panel 10 is held to the temperature of 30 deg.C, and a blue pigment dispersion liquid is applied thereto, and then a blue pigment layer 20 is obtained. Next, the pattern exposure is performed by using a shadow mask, and the development is performed by using an alkaline aqueous solution, so as to form a blue pigment layer 30B. Similarly, a green pigment layer 30G and a red pigment layer 30R are formed. A blue phosphor layer 40B, a green phosphor layer 40G, and a red phosphor layer 40R are formed by being faced to the pigment layers 30B to 30R.

Abstract: PURPOSE:To prepare a display having a fluorecent layer with a filter attached, thus improved in brightness and contrast. CONSTITUTION:A patterned light-absorption layer 2 is formed on the inside surface of the face plate 1. Then, a pigment dispersion composition is coated to form a blue pigment layer 4B and a fluorescent slurry is applied to provide the blue light-emitting fluorescent layer 5B. At this time, jince the pigment dispersion composition has resistance to overcoating, the composition does not cause migration into the fluorescent slurry. Thereafter, exposure through the mask and development are effected to give the blue pixel 6B with a blue filter attached. Since the pigment dispersion composition has an antinomic properties between the exposed parts and the unexposed parts due to the action of the dispersant, good patterning can be performed. These processes are repeated on the colors 6G and 6R, respectively, to prepare the fluorescent layer with filters attached.

Abstract: PURPOSE:To easily obtain the uniform reflection preventive effect by gradually changing the thickness of a single-layer film so as to make it largest near the center section of a face plate and thin at the peripheral section. CONSTITUTION:A fluorescent layer 10 is formed on the inner side of a face plate 9, and the observer observes pictures displayed on this portion. In addition, a reflection preventing film 8 is formed on the outer surface of the face plate 9. This reflection preventing film is made of a material having a refraction factor lower than the refraction factor 1.52-1.54 of the face plate glass, and its thickness is gradually changed so as to be made thick at the center section of the face plate and thin at the peripheral section. The thick portion of the film at the center section may be adjusted to 0.22/nmum or less and the thin portion at the peripheral section to 0.04/nmum or more. Accordingly, the desired reflection preventive effect can be obtained at any point on the face plate 9.

Abstract: PURPOSE:To obtain a charge/reflection preventing film having sufficient sticking strength in a short time by applying a solution containing polyalkyl siloxane on a face plate end forming a SiO2 film on the surface of the face plate by condensation reaction. CONSTITUTION:A solution containing polyalkyl siloxane is applied to the face plate surface of a cathode-ray tube, and a SiO2 film is formed on the face plate surface by condensation reaction. That is, the solution contains some siloxane bonding from the start in the solution state before being applied to the face plate, i.e., before sintering or drying; thus the film has a strong sticking force even at the stage when the condensation reaction of silanol group is not progressed so much. Accordingly, a sufficient sticking force is obtained under loose calcination conditions (lower temperature or shorter time), and a sufficient charge preventive effect is obtained.
