A light-shielding film provided on each light-shielding slope of the Fresnel surface, a conductive transparent thin film covering the entire surface of the Fresnel surface, and a ground attached to the peripheral edge of the transparent substrate so as to be electrically conductive with the transparent thin film. The application consisting of the means was filed first. Such a filter can prevent the above-mentioned adverse effects caused by reflected glare, and can also provide effects such as removing static electricity generated on the display screen to obtain high-quality images.

。Hereinafter, an embodiment of the method for manufacturing a display filter according to the present invention will be described based on FIGS. 1 to 6. First, in FIGS. 1 to 4, which sequentially show the manufacturing process of the filter body, ① is a non-conductive transparent substrate made of thermoplastic resin such as 7cryl (Fig. 1) ② is a transparent substrate Ⅰ, on one side of which a thermoplastic antistatic material with a thickness of about 1 μm is formed by printing method etc. (Figure 2)

バーである。This transparent thin film 2 uses tin oxide or titanium oxide whose surface is coated with tin oxide as a main component, and acrylic resin or the like as a binder. Furthermore, after preheating both the transparent substrate 1 and the transparent thin film 2, the surface on the side of the transparent fill 12 is formed into a Fresnel surface by pressing as shown in FIG. 3, and the other surface is formed into a display screen (not shown). The whole is molded into a curved or flat shape so as to match. 3 is a transparent thin film 2 on the light shielding surface 1a of the Fresnel surface.
It is a light-shielding film made by applying black paint etc. on top (Figure 4).
In forming the light-shielding film 3, a black paint is first applied to the entire Fresnel surface of the transparent thin film 2, and then a portion of the black paint corresponding to the light-transmitting surface lb is applied to the previously applied photosensitive material. This is done by removing it by a chemical cleaning method or the like accompanying the exposure process. A grounding means 5 is attached to the filter body 4 formed in this way as shown in FIGS. A connecting member 8 is connected to the transparent substrate 1 and caulked through the insertion hole IC of the transparent substrate 1, and 8 is a cover for molding the connecting member 7 and the like.

ことができる。According to the method for manufacturing a display filter according to the present invention, first, since the transparent thin film 2 is formed on the flat transparent substrate l, it is possible to freely select the optimal forming method such as printability. The thickness of the thin film 2 can be easily made uniform, and its surface can be finished into a nearly mirror-like finish.

悪影響をなくすことができるのは勿論である。Furthermore, after this, the transparent thin film 2 side is further processed into a Fresnel surface, but since the film thickness of transparent 11192 has already been made uniform, it has excellent optical properties as a Fresnel surface, that is, it completely prevents the occurrence of image blur, etc. Be able to prevent it. Furthermore, the light shielding film 3 corresponding to the light shielding surface 1a of the Fresnel surface is such a transparent thin film 2.
Since it is formed on the outside of the transparent thin film 2, no surface reflection occurs at all on the inside transparent thin film 2, so that a good display image can be obtained in this respect as well. On the other hand, when applied to a VDT, the static electricity generated on the display screen is also generated on the Fresnel surface of the non-conductive transparent substrate l, but this static electricity is removed by the grounding means 5 through the conductive transparent thin film 2. Since it is possible to prevent the generation of an electric field between the operator and the display screen, it is of course possible to eliminate any adverse effects on the human body during operation.
尚、上記実施例における透明薄膜２はスプレー方式若し
