In the conventional manufacturing method for anti-glare cathode ray tubes as described above, fine irregularities are formed on the outer surface of the glass face portion by etching, but generally glass is not polished or etched. When this happens, there is a problem in that the surface becomes soft and easily scratched, and furthermore, the outer surface is even more prone to scratches and scratches due to the unevenness. In addition, the above outer surface is
In daily use of televisions, computer displays, etc., they are often directly rubbed, for example when cleaning dirt from them, and there is a high possibility that they will be scratched. Moreover,
Scratches on a relatively uniform uneven surface are very noticeable and are extremely inconvenient for anti-glare cathode ray tubes.

線硬化形樹脂に浸漬する方法を利用できる。 FIG. 2 is an enlarged view of the main part of FIG. In the figure, 6 is a protective layer on the outer surface of the face portion 2, which is coated with an ultraviolet curing resin such as acrylic resin.
By curing this resin by irradiating it with ultraviolet rays, a film is formed as an anti-glare layer that protects the uneven surface. Examples of the ultraviolet curable resin include Fuji Hard (trade name: Fujikura Kasei Co., Ltd.). As a method for applying the ultraviolet curable resin to the outer surface, a method of spraying the outer surface with the ultraviolet curable resin or a method of immersing the outer surface in the ultraviolet curable resin can be used.

眩形陰極線管を完成させる。 As shown in FIG. 3, in this embodiment, a protective layer 6 is formed on a cathode ray tube that has undergone an evacuation process 11, which is the final stage of the manufacturing process. First, in steps 12 and 13, the outer surface of the face portion 2 is degreased, cleaned, and dried, and then, in step 14, an ultraviolet curable resin is applied to the portion of the outer surface where the protective layer 6 will be formed using the method described above. Then, a resin film is formed. Thereafter, in step 15, the resin film is dried by infrared irradiation, and further, in step 16, the resin film is cured by ultraviolet irradiation.
The resin film is used as a protective layer 6, and the next step 17 is carried out to complete an anti-glare cathode ray tube.

し、目障りな表面反射を軽減する。 In the above configuration, the ultraviolet curable resin is
It has good adhesion to the above outer surface which is glass.
Furthermore, when cured, it has high hardness and is hard to be scratched, so it becomes a protective layer 6 on the outer surface with fine irregularities formed by etching. Furthermore, since the ultraviolet curable resin is applied by the method described above, the protective layer 6 also naturally has unevenness similar to the outer surface, which diffuses the reflected image and causes unsightly surface reflections. Reduce.

すくなる。 In addition, the overall light transmittance of the face portion 2 is adjusted by adding a dark pigment such as carbon black or ultramarine to the ultraviolet curable resin applied to the outer surface to color the protective layer 6. This makes it possible to improve the contrast ratio of the screen.
In addition, the protective layer 6 prevents screen blurring due to light scattering on the outer surface under bright external light incident conditions, which is a problem unique to cathode ray tubes with roughened outer surfaces.
This can be reduced by darkening the color, making the screen easier to see.

As described above, according to the present invention, fine irregularities are formed on the outer surface of the face part by mechanical or chemical etching with good manufacturing efficiency, and the ultraviolet curable resin coated to cover the irregularities is irradiated with ultraviolet rays. By curing the surface, the uneven surface is strengthened and protected, and although it is formed by etching, it is possible to reliably prevent the fine uneven surface from being scratched by daily use. Therefore, it is possible to maintain the desired anti-glare effect in the best condition for a long period of time.
