る。The conventional method for manufacturing anode substrates for optical display tubes involves forming conductor patterns and wiring patterns that will become display segments on a plate substrate, and then forming a thin film insulating layer over the entire surface. Then, remove the thin film insulating layer on the conductor pattern,
A crab light body is formed on the conductor pattern by lightning deposition or the like. However, in the method for manufacturing an anode substrate for a crab light display tube having the above structure, a thin film insulating layer is formed on the entire surface of the plate substrate, and then the conductive pattern portion is removed by photoetching, so a process of forming a thin film insulating layer and a photoetching process are required. There were drawbacks. Therefore, the object of the present invention is to provide a method for manufacturing an anode substrate for a light display tube that simplifies the manufacturing process and sharpens the edges of the peripheral boundary of the phosphor by using a photoresist for photo-etching as an insulating layer. It is something to do.

、実施例を用いて説明する。In order to achieve such an object, the present invention forms a conductor pattern and a wiring pattern on a plate substrate, coats a photoresist on the part excluding the conductor pattern to form an insulating layer, and then applies a photoresist to the part excluding the conductor pattern. After forming the light body, the photoresist is removed by baking to produce an anode substrate for a crab light display tube, which will be described below using examples.

る。In the figure, 1 is a plate substrate, 2a and 2b are conductor patterns and their wiring patterns formed on the plate substrate 1, and 3 is a crab light coated on the conductor pattern 2a. Next, a method of manufacturing the anode substrate for a crab light display tube having the above structure will be explained. First, plate substrate 1
A conductor pattern 2a and a wiring pattern 2b are formed thereon.

成することができる。Then, a photoresist for photo-etching is applied to the area excluding the conductor pattern 2a. Then, a crab light body 3 is formed on the conductive pattern 2a by electrodeposition or the like.
Then, the photoresist is removed by baking (for example, at 500° C. for 5 to 10 minutes), and an anode substrate can be manufactured. In this case, the withstand voltage of the photoresist as an insulating layer is 100 V or more, and the crab photoresist 3 can be formed on the conductive pattern 2a by, for example, electroplating.

シャープになる効果がある。Then, by completely removing the photoresist by baking, the wiring pattern 2b portion is exposed and the plate current is thought to increase. However, by reducing the wiring pattern 2b portion as much as possible, the area of the conductor pattern 2a Since it is possible to make the ratio between the area of the exposed portion of the wiring pattern 2b and the area of the exposed portion of the wiring pattern 2b about 10:1, the effect on the luminous efficiency of the L-light display tube is slight. Furthermore, since the photoresist can be completely removed by baking, it goes without saying that it will not affect the optical display tube. As described above in detail, according to the method of manufacturing an anode substrate for a crab light display tube according to the present invention, an insulating layer is formed by coating a photoresist, so that the manufacturing method can be simplified and This has the effect of sharpening the edges of the light body.
