2. Description of the Related Art A plasma display has been proposed as one type of display. This plasma display employs a principle in which a gas is filled in a phosphor serving as a pixel, a high voltage is applied to the gas to cause discharge, and the discharge causes the phosphor to emit light.

[0003] The plasma display generates an electromagnetic wave which causes a malfunction of an electronic device or affects a human body at the time of its operation. Therefore, a front plate for shielding the electromagnetic wave is provided on the front surface thereof.

The manufacturing of this front plate has the following problems.

[0005] That is, when laminating the constituent members constituting the front plate, many laminating steps of laminating one by one by thermocompression bonding via an adhesive are required, and thus many steps are required. The productivity is low by that much, and the number of cases where foreign matter enters between the constituent members increases as the number of bonding steps increases, and distortion due to lamination tends to occur due to thermocompression bonding via an adhesive ( It is extremely difficult to maintain quality, such as unevenness on the surface, which makes it easier to diffuse external light.

The present invention has been made to solve the above-mentioned problems, and it is possible to dramatically improve the productivity by simplifying the production, and to surely maintain the quality. An object of the present invention is to provide a novel and innovative method of manufacturing a front panel for a plasma display.

4 to 9 illustrate a second embodiment, which will be described below.

Both the first embodiment and the second embodiment relate to a method of manufacturing a front panel a for a plasma display having a function of shielding an electromagnetic wave generated from a plasma display by a mesh-shaped conductive material 1. The lamination process of the substrates 2 and 3 is performed twice.

Hereinafter, a specific description will be given.

<First Embodiment> Transparent glass plates are used as the substrates 2 and 3. Note that the substrates 2 and 3 are not limited to glass plates, but may be suitably adopted as long as they have a configuration exhibiting the characteristics of the present embodiment, such as a plastic plate (polycarbonate plate or acrylic plate). In this case, it is preferable to provide a hard coat layer for reinforcement at least on the surface on which anti-reflection treatment described later is performed.

A mesh-shaped conductive material 1 is provided between the substrates 2 and 3.

As the mesh-shaped conductive material 1, a film 5
A copper foil 6 is laminated via an adhesive, the copper foil 6 is subjected to an etching treatment, and a mesh-shaped conductive material 1 having a structure in which a mesh-shaped copper foil 6 is laminated on a film 5 is employed. As the mesh-shaped conductive material 1, for example, a mesh-shaped conductive material 1 obtained by bonding a fiber woven mesh to a film or a mesh-shaped conductive material 1 obtained by printing a conductive paste on a film is used. Or a mesh-shaped conductive material 1 obtained by screen printing or offset printing on a film.
For example, any configuration that exhibits the characteristics of the present embodiment, such as the configuration shown in FIG.

Subsequently, a UV curable resin 4 is applied between the lower substrate 2 and the mesh conductive material 1 and between the mesh conductive material 1 and the upper substrate 3 (see FIG. 1).

The UV-curable resin 4 is used for laminating and fixing the substrates 2 and 3 and the mesh-shaped conductive material 1.
Between the mesh-shaped conductive material 1 and the mesh-shaped conductive material 1
Having an appropriate viscosity (500 to 3000 CPC) such that the resin is maintained at a predetermined thickness (10 to 200 μ) in which the resin is embedded. Specifically, urethane acrylate U
V-curable resin 4 is employed. The same applies between the substrate 2 and the mesh-shaped conductive material 1.

In this embodiment, a near-infrared absorbing agent is added to the UV-curable resin 4 in advance so that near-infrared rays generated from the plasma display can be shielded.

Subsequently, the roller 7 is rolled on the upper substrate 3 to bring the upper and lower substrates 2 and 3 and the mesh-shaped conductive material 1 into a completely adhered state without bubbles (see FIG. 2). .

Subsequently, the UV-curable resin 4 is irradiated with UV light (this UV light is light including a UV region) to be cured, whereby the substrates 2 and 3 and the mesh-shaped conductive material 1 are cured. The front panel a for plasma display is manufactured by being integrated (see FIG. 3). The UV light may be irradiated from either side because the upper and lower substrates 2 and 3 are transparent.

When the UV-curable resin 4 is cured, the UV-curable resin 4 hardly undergoes curing shrinkage, so that the close contact between the upper and lower substrates 2 and 3 and the mesh conductive material 1 is maintained as much as possible. You.

<Second Embodiment> The second embodiment is a case where the lamination process of the upper and lower substrates 2 and 3 and the mesh-shaped conductive material 1 is performed in two steps. The UV curable resin 4 is disposed between the lower surface of the mesh-shaped conductive material 1 and the upper surface of the substrate 2, and the roller 7 is rolled on the mesh-shaped conductive material 1. By moving the substrate, the substrate 2 and the mesh-shaped conductive material 1 are completely adhered to each other without air bubbles (see FIGS. 4 and 5). Subsequently, the UV curable resin 4 is cured by irradiating UV light. Then, the substrate 2 and the mesh-shaped conductive material 1 are integrated (see FIG. 6), and then the substrate 3 is disposed above the mesh-shaped conductive material 1, and the lower surface of the substrate 3 and the mesh-shaped conductive material 1 A UV curable resin 4 is disposed between the substrate and the upper surface of the mesh-shaped conductive material 1 by rolling the roller 7 on the substrate 3. The substrate 3 is brought into a completely adhered state without any bubbles (see FIGS. 7 and 8), and subsequently, the UV curable resin 4 is cured by irradiating UV light to form the mesh-shaped conductive material 1 with the substrate 2. And the substrate 3 are integrated to produce a front panel a for plasma display which is optically superior from a more careful process (see FIG. 9).

As described above, the front and back surfaces of the front plate a for plasma display according to the first and second embodiments are subjected to anti-reflection treatment and mounted on the plasma display.

Therefore, in the first embodiment and the second embodiment, the productivity can be greatly improved by simplifying the production as compared with the prior art, and moreover, foreign matters enter between the constituent members. The front panel a for plasma display with excellent optical characteristics is obtained, such that the maintenance of the quality is surely achieved, for example, without the occurrence of distortion or citron skin due to lamination. Become.

Further, since the UV-curable resin 4 is excellent in transparency, it does not distort the image of the plasma display when the front panel a for a plasma display is used.

Since the UV-curable resin 4 hardly undergoes curing shrinkage, the substrates 2, 3 and the mesh-shaped conductive material 1 can be integrated well, and the substrates 2, 3 are meshed with the mesh-shaped conductive material. Distortion does not occur in the plasma display front plate a formed by laminating the material 1.

A copper foil 6 is laminated on the above-mentioned film 5 via an adhesive as the mesh-shaped conductive material 1.
Is etched to form a mesh-like copper foil 6 on the film 5.
When a mesh-shaped conductive material 1 having a structure in which is laminated is used, or when a mesh-shaped conductive material 1 obtained by adhering a fiber woven mesh to a film via an adhesive is used, it is used for this bonding. There is a problem such that the external light is likely to be irregularly reflected by the applied adhesive (the surface of the adhesive is further roughened by the etching treatment, and the external light may be irregularly reflected). In this regard, according to the present embodiment, the surface of the adhesive can be smoothed by the UV-curable resin 4 for bonding the constituent members together (transparency is achieved). Therefore, the front panel a for plasma display having excellent optical characteristics that does not irregularly reflect external light can be efficiently obtained.
