Abstract: A display device capable of simplifying connection between a drive circuit and lead-out wirings led out of electrodes and being small-sized while keeping a size of an image plane from being reduced. A part of supports for holding an anode substrate and a cathode substrate spaced from each other at a predetermined interval is formed so to be conductive and is interposedly arranged between the anode electrode and a lead-out wiring formed on the cathode substrate, to thereby provide an anode lead-out wiring on the cathode substrate. Such construction permits the anode lead-out electrode to be arranged so as to extend in the same direction as a cathode lead-out electrode or a gate lead-out electrode, to thereby facilitate connection of the wirings. Also, the anode substrate can be decreased in size because a region for the anode lead-out wiring is eliminated.

Abstract: A process for transparent conductive film wiring board mfr. comprises depositing a metal film on a substrate for forming a transparent conductive film and then structuring the film by laser treatment. Alternatively, the process comprises (a) forming a black indium-tin oxide film (3) on an insulating, heat conductive substrate (1); (b) treating the film (3) with a laser (4) to obtain a wiring pattern; and (c) calcining in air to convert the black film (3) into a transparent ITO film. The subsrate is a glass substrate (1) with a SiO2 coating (2). During the black ITO film laser treatment step to produce the wiring pattern, the metal of the black film evaporated by the laser is removed by an extractor (5) in the laser (4). The exposed substrate portions remaining after the laser treatment are coated with an insulating layer prior to the calcination step. USE/ADVANTAGE - The processes are used esp. for mfg. wiring boards used as front panels for display devices, such as LCDs, VFDs and PDPs. The processes are completely dry, and are thus simpler and less expensive than prior art processes.

Abstract: PROBLEM TO BE SOLVED: To provide a fluorescent character display tube which makes less differences among luminances of luminous areas to occur by forming a display area extending near inner sides. SOLUTION: Both ends of filament cathodes 11 are stretch-installed to anchor members 12 and 13 whose shapes are different from each other, respectively. Fixing portions 12c and 13c are formed at tips of arms 12b and 13b which extend in prescribed directions from bases 12a and 13a of the anchor members 12 and 13. The arm 12b and the arm 13b orient to the same direction when the filament cathodes 11 are stretch- installed by disposing a pair of the anchor members in line simmetries relative to bisectors of the cathodes 11. A first group A of the filament cathodes 11 is disposed near one peripheral side of the fluorescent character tube, and a second group B of the filament cathodes 11 is disposed near another peripheral side of the fluorescent character tube. The group A and the group B are disposed while shifting their positions each other in the long direction of the filament cathodes 11. The display area can be expanded because luminous areas can be disposed near the inner side of a hermetic container, and the differences among the luminances of luminous areas can be suppressed because the filament cathode positions for the luminous area positions are kept fixed because shiftings of the filament cathodes 11 by their thermal expansions are limited to parallel shiftings.

Abstract: PURPOSE: To improve positioning displacement of supports which support a vacuum glass container to contain a display apparatus in at a prescribed distance. CONSTITUTION: An arrangement plate is produced by forming a second arrangement plate 3 so formed as to be thick under a first arrangement plate 2 so formed as to be thin. The diameter of a supporting column hole formed in the first arrangement plate 2 can be highly precise since the plate is so formed as to be thin. The arrangement plate can be used as a jig utilized in the case support members are set in a vacuum glass container and the degree of a positioning shift from an arrangement position of a support member 1 can be improved.

Abstract: PROBLEM TO BE SOLVED: To smoothen the inside of an anode substrate for a display tube by a smooth layer of a color filter. SOLUTION: Red, green and blue color filters R, G, B made of inorganic pigment materials are formed respectively on a borosilicate glass substrate 1 (1). A smooth layer 2 comprising low fusing point glass of ZnO-B2 O3 -SiO2 is formed (3). A photoresist 5 is coated on an acid-proof protection film 3 and a transparent conductive film 4, and is exposed through a mask 6 (4)-(6). After development (7), the substrate 1 is etched (8), and washed (9). Phosphor layers (r), (g), (b) are formed (10). The low fusing point glass comprising mainly ZnO and composing the smooth layer 2 has a small temperature difference between its softening point and its distortion point. Since the distortion point of the low fusing point glass is about 500 deg.C and is nearly same to a baking temperature in a following process for display tube manufacture, the transparent conductive film 4 is free from disconnection failure. Softening point of the low fusing point glass composing the smooth layer 2 is sufficiently low compared with a distortion point of the glass substrate 1 to be safe.

Abstract: PROBLEM TO BE SOLVED: To manufacture an inorganic color filter free from any step on the surface of an anode substrate. SOLUTION: A resist 2 of a glass substrate 1 is machined to the prescribed pattern by a photo-lithography method, and a groove 4 is formed through the etching. An inorganic blue filter paste B is coated on the surface of the glass substrate 1, and fired. The glass substrate 1 is polished to remove the blue filter B projected from the groove 4 through polishing. A red filter R and a green filter G are formed in a similar process. A smooth layer 5 is formed. A transparent conductive film 6 is formed by the photolithography method. A substrate of the structure in which the inorganic color filter is embedded in the groove of the substrate can be manufactured. Even when the film thickness of the color filter is increased, the film thickness of the color filter can be canceled by changing the depth of the groove to be formed in the substrate, and the substrate having a flat filter can be stably obtained.
