2. Description of the Related Art Conventionally, an electronic device for generating an electromagnetic wave which a person directly approaches and uses, for example, an electronic tube for a display such as a plasma display, has a standardized intensity of the electromagnetic wave in consideration of the harmful effect of the electromagnetic wave on the human body. It is required to keep it within. Further, in the plasma display panel (hereinafter also referred to as PDP), since the light emission utilizes plasma discharge, the frequency band is 30 MHz to 13 MHz.
Since unnecessary electromagnetic waves of 0 MHz are leaked to the outside, it is required to suppress the electromagnetic waves as much as possible so as not to adversely affect other devices (for example, information processing devices). In order to meet these demands, in general, in order to remove or attenuate the electromagnetic waves flowing out of the device from an electronic device that generates electromagnetic waves,
An electromagnetic wave shield is used in which the outer peripheral portion of an electronic device that generates electromagnetic waves is covered with a suitable conductive member. In a display panel such as a plasma display panel, it is common to provide an electromagnetic wave shielding plate having good transparency on the front surface of the display.

An electromagnetic wave shielding plate having an ITO film formed on a transparent substrate is excellent in transparency and generally has a light transmittance of about 90% and can form a uniform film on the entire surface of the substrate. Therefore, when used in a display or the like, there is no concern about the occurrence of moire or the like due to the electromagnetic wave shielding plate. However, in an electromagnetic wave shielding plate having an ITO film formed on a transparent substrate, techniques such as vapor deposition and sputtering are used to form the ITO film, so the manufacturing apparatus is expensive and the productivity is generally high. Since it is inferior, there is a problem that the price of the electromagnetic wave shielding plate itself as a product becomes expensive. Further, the electromagnetic wave shielding plate having the ITO film formed on the transparent substrate is inferior in conductivity to the electromagnetic wave shielding plate having the mesh made of the metal thin film by one digit or more, so that the electromagnetic wave emission is relatively weak. It is effective for the target object, but when it is used for a strong target object, its shielding function becomes insufficient and leaked electromagnetic waves are emitted, which may cause the problem that the standard value cannot be satisfied. is there. In the electromagnetic wave shielding plate having the ITO film formed on the transparent substrate, if the thickness of the ITO film is increased in order to increase the conductivity, the conductivity is improved to some extent, but in this case, the transparency is significantly lowered. The problem occurs. In addition, there is a problem in that the manufacturing cost becomes higher by making the thickness further thick.

Further, a transparent glass or plastic substrate having a mesh formed of a metal thin film is externally processed by etching using a photolithography method, so that fine processing is possible and a high aperture ratio (high transmission) is achieved. rate)
Since the mesh can be created and the mesh is formed of a metal thin film, the conductivity is much higher than that of the ITO film and the like, and the advantage that strong electromagnetic wave emission can be shielded is provided.

The member for electromagnetic wave shield of the present invention has the above-mentioned structure, and thus, in terms of productivity and quality,
Produced by a flexographic printing method that can be quantitatively and cost-effectively provided. Also, it is possible to provide a member for electromagnetic wave shielding in which a mesh having an electromagnetic wave shielding effect is arranged on one surface of a film base material in terms of quality. I am supposed to. This makes it possible to provide a large amount of an electromagnetic wave shielding plate having good transparency and electromagnetic wave shielding property for a display such as PDP as shown in FIG. 4 at an early stage. Specifically, while transporting a web-shaped film substrate sandwiched between the plate cylinder and the impression cylinder, the electromagnetic wave shielding ink transferred from the ink supply roll such as an anilox roll to the plate cylinder, from the plate cylinder, It is a method of continuously transferring and forming on one surface of a film substrate, and a CTP (Compu
The flexographic printing method using a ter To Plate) plate can be used to remove a mesh or the like made of an electromagnetic wave shielding ink.
A member for electromagnetic wave shielding, which has an electromagnetic wave shielding property, in which a pattern in which two or more lines having a line width L intersect is disposed on one surface of a film substrate, and the film thickness at the line intersection is 1 . By being 2 to 3 times, the area of the intersection part of the line having the line width L is 2 to 2 times L × L.
This is achieved by being 30 times. For more details, see CTP (Computer To Plat) on the plate cylinder.
e) By using flexographic printing with a plate,
The entire pattern can be formed into a thin film, and only the intersections can be made thick, and the thick portions function as spacers, preventing blocking, winding the film base roll, and unwinding smoothly. It is possible to achieve thin lines and mass production. Also, by making the film thickness at the line intersection point thicker than the line portion,
Good conductivity can be obtained. In addition, blocking means blocking of the film base material when the film base material is wound up on a roll, which causes wrinkling of the film base material and peeling of the film base material.

A conductive ink or a magnetic ink is used as the electromagnetic wave shielding ink 14. The conductive ink exhibits an electromagnetic wave shielding effect mainly by reflection of electromagnetic waves. As the conductive ink, the dry film has a volume resistivity of preferably 10 −3 Ω · cm to 10 −6 Ω · cm, more preferably 10 −4 Ω · cm to 10 −5 Ω · cm. As the ink, a conductive powder is dispersed in a vehicle to form an ink. As such a conductive powder, for example, silver, gold, platinum, copper, aluminum, nickel, graphite, tin, etc. may be used alone or in combination of two or more. As the binder resin in the vehicle, for example, acrylic resin, urethane resin, polyester resin, etc. may be used alone or in combination of two or more. The shape of the conductive powder is preferably scale-shaped rather than spherical or ellipsoidal, because the conductivity is better. Further, the conductive powder may be doped with another metal or a metal oxide in order to improve transparency. For example, it is ITO (indium-tin oxide) or the like. On the other hand, the magnetic ink has an electromagnetic wave shielding effect mainly by absorbing electromagnetic waves. As the magnetic ink, an ink prepared by dispersing magnetic powder in a vehicle is used. Examples of such magnetic powder include Mn-Zn.
Powders having an average particle size of about 1 μm to 10 μm, such as ferrite such as ferrite, soft iron, silicon steel, carbonyl iron, sendust iron, permalloy, and the like are used. As the binder resin in the vehicle, the same binder resin as in the case of the conductive ink is used.

Next, CTP (Computer To
The plate) will be described with reference to FIG. 3 while comparing it with the conventional flexographic printing plate. 3 (a) to 3 (e) are cross-sectional views of the manufacturing process of the CTP plate, and FIG. 3 (a1) and FIG. 3 (c1) to FIG.
(E1) is a process sectional view of a conventional flexographic printing plate.
First, a UV curable resin 3 for plate making is formed on one surface of a base substrate 31 such as PET (polyethylene terephthalate).
2. A mask layer 33 for forming a mask is formed, and the entire surface is exposed from the base material 31 side (referred to as back exposure). (FIG. 3A) As a result, the UV curable resin 32 on the side of the base material 31 is cured and becomes insoluble in the developing solution for the later development.
Then, a predetermined region of the mask layer 33 is irradiated with laser light to open the mask layer 33, and a mask made of the mask layer 33 is manufactured. (FIG. 3B) As a result, a mask made of a mask layer is laminated on the surface of the UV curable resin 32. Next, the UV curable resin 32 is exposed through the mask made of the mask layer 33 on the UV curable resin thus produced (FIG. 3C), and further developed. (FIG. 3 (d)) In the conventional production of a flexographic plate, a mask layer was not provided, and the entire surface was exposed from the base material 31 side (referred to as back exposure) (FIG. 3 (a1)). The masking film 36 is held on the UV curable resin 32 disposed on the material 31 with a vacuum sheet 37, and the two are exposed to each other through the masking film 36 while being vacuum-adhered to each other (see FIG.
1)), and was further developed. (FIG. 3 (d1)) The exposure through the mask made of the mask layer 33 laminated on the surface of the UV curable resin 32 is more effective than the exposure in the conventional flexographic plate fabrication (FIG. 3 (b1)). Since the exposed portion is exposed to the air, the convex portion 38, which is the insolubilized portion after development, becomes thinner than in the conventional flexographic plate production. After this, the UV light 34 is further applied to the entire insolubilized portion 32b. The same applies to the production of a conventional flexographic plate. Here, FIG. 3A to FIG.
The plate shown in FIG. 3 (e) manufactured by the process shown in FIG.
It is called a TP (Computer To Plate) plate, and compared to the conventional flexo plate shown in FIG. 3 (e1),

In this example, the film thickness of the line intersection 17 is 1.2 to 3 times the height of the lines 15 and 16, and the area of the intersection 17 of the line having the line width L is L × L = 2. Although it is set to 30 times, the reason for this will be briefly described. The film thickness h1 of the intersection 17 shown in FIG.
In the flexographic printing method using the apparatus shown in FIG. 2, it is preferable that the ratio h1 / h2 of the film thickness h2 is large in order to prevent blocking, but if the ratio h1 / h2 is smaller than 1.2, blocking Is not effective, and if the ratio h1 / h2 is larger than 3, it is easy to drop out, and eventually the ratio h1
It is preferable that / h2 is 1.2 to 3. In addition, the ratio (S / L) of the area S and L × L in the plan view of the rectangular portion 19
When (L × L)) is less than 2, the amount of ink transfer is small, and in view of the aperture ratio of the mesh portion 11, 30 is preferable, and in the end, the area S and L × L in the plan view of the rectangular portion 19 are
The ratio (S / (L × L)) is preferably in the range of 2 to 30.
