A mesh-like grid is installed between the electrodes. Recently, mesh grids have been removed to reduce costs, improve visibility, and improve display quality. A fluorescent display tube with a structure (
Metschless) has been devised.

発生している。FIG. 1 shows a front view of a display pattern 2 of a meshless fluorescent display tube according to the prior art and a strip 1 provided to surround the display pattern 2. FIG. 2 shows a cross-sectional view taken along the line A-A' of the segment part in FIG. An anode segment 2' and a grid electrode 1 are disposed thereon, and each is connected to a power supply line 4 through a through hole 6. Incidentally, the phosphor layer forming the display pattern 2 is of course laminated on the anode segment 2'. According to the zero structure, the phosphor layer forming the display pattern 2 has the power supply line 4, the through hole 6, and the insulating glass layer 5 as described above.
The manufacturing process, which requires successive lamination of the phosphor layers 2, which are the display pattern of the anode segment electrodes 2', is also extremely complex, and requires many steps, which has become a way to reduce costs. As shown in Figure 3, if the pinholes 7 generated in the insulating glass layer 5 continue and break, the grid electrode 1 or segment electrode 2' made of graphite, which is commonly used at present, A short-circuit occurs in the power supply line 4, which causes a problem in terms of reliability and quality. In addition, in the conventional electrode structure formed by silk screen printing, the edges of each of the grid electrode 1 and segment electrode 2 sag (flow), causing short circuits and other defects in terms of reliability and quality. are doing.

性も大巾に向上した０According to the present invention, the electrode structure as shown in FIG. 6 has no three-dimensionally intersecting parts and can be processed entirely in a two-dimensional manner. This is due to a technical difference in that the minimum adjacency distance for thick film printing technology is 0.25 m1, while for thin film technology it is 0.003 mm. Therefore, the present invention is characterized in that the anode segment 8 and the grid electrode 9 are all formed on the same plane using thin film technology.The present invention simplifies the stain electrode structure and shortens the process, reducing the cost. Reliability has also been greatly improved due to the fact that it is down to a large width, requires an insulating glass layer, and the parts that intersect three-dimensionally are bad.
