The filter substrate comprises a glass substrate and has a front surface, a rear surface, and four side surfaces. The filter substrate is disposed so that the front surface is farther from the display panel than the rear surface, and each of at least two side surfaces facing each other out of the four side surfaces has at least one fitting part, and the filter substrate is supported by a support member disposed on the side of the side surfaces of the filter substrate, and the support member has recesses fitted to the fitting parts respectively.

Description

  The present invention relates to a filter substrate installed in front of a plasma display device, and a plasma display device having such a filter substrate.

  In an FPD (Flat Panel Display) device such as a liquid crystal display (LCD), a plasma display panel (PDP), and an organic EL (Electroluminescent) display (OELD) applied to a thin-screen television, a “filter substrate” ”Or“ front plate ”is provided with a glass substrate.

  This filter substrate is mainly installed for the purpose of preventing reflection of ambient light, improving the strength of the FPD device, and preventing impact damage of the FPD device. In the case of a plasma display panel, the filter substrate also has a role as an electromagnetic wave shield.

  For example, Patent Document 1 describes a plasma display device having a filter substrate having a mesh film installed on the back surface in order to form a shield structure in the device.

JP 2006-58868 A

  In the case of the conventional plasma display device, the filter substrate is supported by the front support member in a state where the periphery of at least the front side (viewing side of the plasma display device) is covered. Therefore, on the front surface of the plasma display device, the front support member protrudes from the filter substrate.

  On the other hand, recently, from the viewpoint of further improving the design of the plasma display device, there has been a demand for a structure that makes the front support member “protruding” inconspicuous and gives the viewer a clean impression. ing.

  In order to meet this demand, in the plasma display device, for example, the front support member is removed, and the filter substrate is displayed via an adhesive or the like installed on the rear side (opposite the viewing side of the plasma display device). It can be considered to be fixed to the side. However, in this case, the filter substrate is supported only by the adhesive, which may cause a problem of peeling or dropping of the filter substrate.

  Thus, there is a problem that it is difficult to achieve both a structure that places importance on design and a structure that stably supports and fixes the filter substrate.

  The present invention has been made in view of such a background, and the present invention provides a plasma display device capable of improving design while having a structure for supporting a filter substrate using a support member. For the purpose. Moreover, it aims at providing the filter substrate which can be used for such a plasma display apparatus.

  Here, in the plasma display device of the present invention, three or all of the four side surfaces may have at least one fitting portion.

  In the plasma display device of the present invention, the at least one fitting portion may be formed by deforming the tip of the glass substrate substantially into an L shape.

  In the plasma display device of the present invention, the at least one fitting portion may be a convex portion having at least one surface tapered.

  In the plasma display device of the present invention, the filter substrate is provided with a functional film on at least one of the front surface and the back surface, and the functional film includes an electromagnetic wave shielding film, an antireflection film, and a near infrared absorption film. May be at least one of them.

In the present invention,
A filter substrate for a plasma display device comprising a glass substrate having first and second main surfaces and four side surfaces,
Among the four side surfaces, at least two opposite side surfaces have at least one fitting portion, and a filter substrate for a plasma display device is provided.

  Here, in the filter substrate of the present invention, the at least one fitting portion may be formed by deforming a tip of the glass substrate into a substantially L shape.

Moreover, the filter substrate which can be used for such a plasma display apparatus can be provided.

In the plasma display apparatus according to the present invention, it is a diagram showing an example of a schematic cross section of a filter substrate and a support member. It is sectional drawing which showed another structure of the filter substrate and the supporting member roughly. It is sectional drawing which showed schematically another structure of the filter substrate and the supporting member. It is sectional drawing which showed schematically another structure of the filter substrate and the supporting member. It is sectional drawing which showed schematically another structure of the filter substrate and the supporting member.

  Hereinafter, the present invention will be described with reference to the drawings.

  In order to better understand the features of the present invention, first, the configuration of a conventional plasma display apparatus will be briefly described.

  FIG. 1 shows a typical cross-sectional configuration diagram of a conventional plasma display apparatus.

  In the example of FIG. 1, the arrow 50 side is the front side of the plasma display device 10, that is, the light emission side, and the arrow 60 side is the rear side of the plasma display device 10.

  As shown in FIG. 1, the conventional plasma display apparatus 10 includes a filter substrate 15, a front support member 20, a rear housing 25, a display panel 30, a substrate 31, an internal metal fitting 35, and the like.

  The front support member 20 has a role of supporting and fixing the filter substrate 15 in front of the display panel 30.

  The rear housing 25 is composed of a rear resin member 25 a and a rear metal member 25 b, and both are fixed by screws 13. The filter substrate 15, the front support member 20, and the rear housing 25 constitute a housing that houses the display panel 30 and the like.

  A conductive gasket 40 is disposed between the inner metal fitting 35 and the rear metal member 25b.

  In the case of the plasma display device 10, it is necessary to form a shield structure surrounding the display panel 30, the substrate 31, and the like for electromagnetic wave interference countermeasures, and the internal metal fitting 35 is used for this purpose. That is, a mesh film is installed on the back surface (display panel 30 side) of the filter substrate 15, and is shielded by the filter substrate 15 (mesh film), the inner metal fitting 35, the gasket 40, the rear metal member 25 b, and the inner metal fitting 35. A structure is formed.

  Here, as apparent from FIG. 1, in the conventional plasma display device 10, the filter substrate 15 is supported by the front support member 20 in a state where the periphery of the front surface is covered. Therefore, the front support member 20 protrudes from the filter substrate 15 on the front side 50 of the plasma display device 10.

  However, recently, a plasma display device that can give a clear impression to the viewer has gained popularity, and the structure in which the front support member 20 projects forward is designed and aesthetically pleasing. There is a problem.

  In order to cope with such a recent trend, in the plasma display device, for example, the front support member 20 is excluded, and the filter substrate 15 is attached to the display panel 30 via an adhesive or the like installed on the back surface. A structure that is fixed only on the side can be considered. However, in this case, the filter substrate 15 is supported only by the adhesive, and there is a risk that the filter substrate 15 is peeled off from the apparatus or dropped.

  As described above, the structure in which the filter substrate 15 is stably supported and fixed using the front support member 20 is inferior in design, whereas the structure in which design is emphasized has a problem in the soundness and safety of the plasma display device. As a result, it is difficult to make both compatible.

On the other hand, the plasma display device according to the present invention is:
A display panel and a filter substrate installed on the light emission side of the display panel;
The filter substrate is made of a glass substrate, and has a front surface and a back surface, and four side surfaces,
The filter substrate is arranged such that the front surface is on the side farther from the display panel than the back surface,
Of the four side surfaces, at least two opposing side surfaces have at least one fitting portion,
The filter substrate is supported by a support member disposed on the side of the filter substrate,
The support member has a recess that fits with each of the fitting portions,
When the display device is viewed from the side of the filter substrate, the front surface of the filter substrate forms a substantially flat plane with the support member.

  With such a configuration, it is possible to provide a plasma display device capable of improving design while having a structure for supporting the filter substrate using the support member. Therefore, by adopting the configuration of the present invention, it is possible to stably support and fix the filter substrate, and it is possible to provide a plasma display device with excellent design.

(Plasma display device of the present invention)
Hereinafter, the configuration of the plasma display apparatus according to the present invention will be described with reference to FIGS.

  FIG. 2 shows an example of a schematic cross section of a plasma display device according to the present invention. FIG. 3 is a schematic partial enlarged cross-sectional view of a filter substrate and a support member used in the plasma display device according to the present invention.

  2, most of the plasma display device 100 is configured in the same manner as the plasma display device 10 shown in FIG. 1, and therefore, the plasma display will be mainly described below with a focus on components that are different from those in FIG. The apparatus 100 will be described.

  As shown in FIG. 2, the plasma display device 100 according to the present invention includes a filter substrate 115, a support member 120, and a rear housing 125. A combination of these members forms a housing having a space inside, and the display panel 130, a substrate, a circuit (not shown), and the like are accommodated in this space.

  In FIG. 2, the upper side is the front side 150 (light emission side) of the plasma display device 100, and the lower side is the rear side 160 of the plasma display device 100. Accordingly, the display panel 130 emits a predetermined image (light) in the upward direction of FIG.

  The filter substrate 115 is installed “front” of the display panel 130 and has a role of shielding electromagnetic waves, blocking near infrared rays, preventing reflection, and the like. The filter substrate 115 includes a glass substrate 118 having a front surface 118A and a back surface 118B, and four side surfaces 118S.

  The support member 120 is disposed on the side surface of the filter substrate 115 and has a role of supporting and fixing the filter substrate 115.

  As described above, in the case of a plasma display device, it is necessary to form a shield structure that surrounds the display panel 130, the circuit, and the like in order to prevent electromagnetic interference. Therefore, in this plasma display device 100, an electromagnetic wave shielding film 195B (see FIG. 3 for details) is installed on the back surface of the filter substrate 115. That is, the electromagnetic wave shielding film 195B on the back surface of the filter substrate 115 to the two internal metal members 135A and 135B to the rear housing 125 to the two internal metal members 135B and 135A constitute a shield structure.

  The internal metal member 135A is fixed by the support member 120 and the screw 113A, whereby the position of the filter substrate 115 is also fixed with respect to the internal metal member 135A. On the other hand, the internal metal member 135B is fixed to the rear housing 125 with screws 113B. Further, the rear housing 125 and the support member 120 are fixed by screws 113C via internal metal members 135A and 135B.

  FIG. 3 is a schematic enlarged cross-sectional view of the filter substrate 115 and the support member 120.

  As shown in FIG. 3, the glass substrate 118 constituting the filter substrate 115 has a ceramic layer 196 in the vicinity of the peripheral portion of the back surface 118B.

  The ceramic layer 196 is installed to improve the design and decoration of the plasma display apparatus 100. However, the installation of the ceramic layer 196 is arbitrary. Moreover, you may install the organic printing layer using resin-made paints etc. instead of the ceramic layer.

  Further, the glass substrate 118 has an electromagnetic wave shielding film 195B on the back surface 118B. A conductive gasket 198 is provided on a part of the electromagnetic wave shielding film 195B. The conductive gasket 198 has a role as a cushion material when the internal metal member 135A (not shown in FIG. 3) and the support member 120 are fixed by the screws 113A.

  Further, the glass substrate 118 may have an antireflection film 195A on the front surface 118A side and a protective film (not shown) on the back surface 118B. However, these installations are optional.

Here, the filter substrate 115 according to the present invention is characterized in that the side surface 118 </ b> S of the glass substrate has a fitting portion (convex portion) 170. Further, the support member 120 has a concave portion 180 having a shape that fits exactly with the fitting portion 170. For example, in the example of FIGS. 2 and 3, the side surface 118 </ b> S of the glass substrate has a convex portion 170 whose one surface is tapered, and the support member 120 fits exactly with the tapered convex portion 170. It has a concave portion 180 with a shape to fit. It is preferable that the fitting part in this invention is a convex part of convex shape like FIG.2, FIG.3 and FIG.4, FIG.5 and FIG.6 mentioned later.

In addition, since the support member 120 is normally comprised with a metal or resin, such a recessed part 180 can be formed comparatively easily.

  In such a structure of the side surface 118S of the glass substrate 118 and the support member 120, the support member 120 can support the glass substrate 118 on the side surface 118S. Therefore, unlike the conventional front support member 20, the support member 120 does not surround the front surface 118 </ b> A of the glass substrate 118.

  Therefore, in such a configuration, the support member 120 does not protrude from the front surface of the filter substrate 115, and a clear impression can be given to the viewer.

  Further, in this configuration, since the filter substrate 115 is supported by the support member 120, there is a risk that the filter substrate 115 may be peeled off or dropped from the device 100 as in a device having no support member. It is suppressed.

  Further, in the configuration of the present invention, in the filter substrate 115, the side surface 118S of the glass substrate 118 is entirely covered by the support member 120 and is not exposed to the surroundings. Therefore, in the configuration of the present invention, it is possible to avoid the problem in the configuration in which the support member 120 is excluded, that is, the problem that the side surface of the glass substrate is exposed and the side surface of the glass substrate is cracked or damaged even with a small impact. it can.

  The characteristics of the plasma display device according to the present invention have been described above using the configuration of the filter substrate 115 and the support member 120 shown in FIG. 3 as an example. However, it is apparent that the effect of the present invention can be obtained even in a configuration different from the configuration shown in FIG.

  Hereinafter, some specific examples of such a configuration will be described with reference to FIGS.

  4 to 7 show other configuration examples of the filter substrate and the support member. In these drawings, other members such as a functional film such as an antireflection film and a gasket are omitted for clarity.

  In the example of FIG. 4, the filter substrate 215 includes a glass substrate 218 having convex portions 270 on the side surfaces. The support member 220 also has a recess 280 configured to fit exactly with the protrusion 270 of the glass substrate 218. In this example, the convex part 270 on the side surface of the glass substrate 218 has a tapered shape on both the front surface and the back surface.

  FIG. 5 shows still another configuration example of the filter substrate and the support member.

  In the example of FIG. 5, the filter substrate 315 includes a glass substrate 318 having a convex portion 370 on the side surface. The support member 320 also has a recess 380 configured to fit exactly with the protrusion 370 of the glass substrate 318. In this example, the convex portion 370 on the side surface of the glass substrate 318 has a shape in which only the rear surface side protrudes.

  FIG. 6 shows still another configuration example of the filter substrate and the support member.

  In the example of FIG. 6, the filter substrate 415 includes a glass substrate 418 having convex portions 470 on the side surfaces. The support member 420 also has a recess 480 configured to fit exactly with the protrusion 470 of the glass substrate 418. In this example, the convex portion 470 on the side surface of the glass substrate 418 has a shape in which the central portion of the side surface protrudes.

  FIG. 7 shows still another configuration example of the filter substrate and the support member.

  In the example of FIG. 7, the filter substrate 515 includes a glass substrate 518 having a fitting portion 570 on the side surface. The support member 520 also has a recess 580 configured to fit exactly with the fitting portion 570 of the glass substrate 518. In this example, the fitting portion 570 on the side surface of the glass substrate 518 is formed by deforming the side end portion of the glass substrate substantially into an L shape.

  It will be apparent that the above-described effects of the present invention can also be obtained when the plasma display device has a combination of a filter substrate and a support member as shown in FIGS. Moreover, it will be apparent to those skilled in the art that these combinations are only examples of configurations that can achieve the effects of the present invention as described above.

  In the above description, only the configuration of one side surface of the filter substrate (or glass substrate) is focused, and the other three side surfaces are not particularly described. However, it is clear that all the other three side surfaces may have the same configuration as the one described side surface, i.e. fittings or protrusions (170, 270, 370, 470, or 570). It is.

  However, the present invention is not limited to a form in which all four side surfaces have such a configuration. For example, only two opposite side surfaces of the filter substrate (or glass substrate) have the fitting portions (170, 270, 370, 470, or 570) as described above, and the remaining two side surfaces are flat. You may comprise by the side.

  Alternatively, the filter substrate (or glass substrate) has the fitting portions (170, 270, 370, 470, or 570) on the three side surfaces as described above, and the remaining one side surface is a flat side surface. As such, it may be configured. In such a configuration, normally, the filter substrate will be arranged with respect to the device such that the side having the flat side surface of the filter substrate corresponds to the upper side of the plasma display device.

(Regarding the filter substrate 115)
Next, the members constituting the filter substrate 115 will be described in more detail with the filter substrate 115 shown in FIG. 3 as an example. It is obvious to those skilled in the art that the following description can be similarly applied to the filter substrates 215, 315, 415, and 515 shown in FIGS.

  As described with reference to FIG. 3, the filter substrate 115 includes a glass substrate 118, various functional films such as an electromagnetic wave shielding film 195B, and a ceramic layer 196 that is optionally installed.

(Glass substrate 118)
The material or the like of the glass substrate 118 is not particularly limited, but a glass substrate with high transmittance and less coloring is desirable. The glass substrate 118 typically has a visible light transmittance Tv of 90.2%, a visible light reflectance Rv of 8.2%, a haze (turbidity) of 0.06%, and a chromaticity value in the xy chromaticity coordinates. x = 0.307 and y = 0.314 are used.

  For example, the glass substrate 118 may be a soda lime glass substrate. Further, the glass substrate 118 may be chemically strengthened.

  Here, “chemical strengthening treatment” means that a glass substrate is immersed in a molten salt containing an alkali metal, and an alkali metal (ion) having a small atomic diameter existing on the outermost surface of the glass substrate is present in the molten salt. This is a general term for technologies that replace alkali metals (ions) with large atomic diameters. On the surface of the glass substrate treated by the “chemical strengthening treatment”, an alkali metal (ion) having an atomic diameter larger than that of the original atoms is arranged. For this reason, a compressive stress layer can be formed on the surface of the glass substrate, whereby the strength of the glass substrate can be increased.

  The thickness of the glass substrate 118 may be in the range of 1.5 mm to 3.5 mm. When the glass substrate 118 is chemically strengthened, the thickness of the glass substrate 118 is preferably in the range of 0.2 mm to 1.0 mm.

(Electromagnetic wave shielding film 195B)
In a normal case, the electromagnetic wave shielding film 195B is formed by applying a thin film forming method such as an evaporation method, a sputtering method, or a CVD method. For example, the electromagnetic wave shielding film 195B can be formed by forming a conductive film on a transparent substrate or transparent resin film by a sputtering method. Such a film may have a near infrared shielding function in addition to the electromagnetic shielding function.

  The conductive film usually includes a metal oxide layer (oxide of In and Sn, oxide of Ti and Zn, oxide of Al and Zn, niobium oxide, etc.) and metal layer (Ag, Ag alloy, etc.) Are alternately stacked. The number of metal layers is preferably n (where n is an integer of 1 or more), and the number of metal oxide layers is preferably n + 1.

  Another example of the electromagnetic wave shielding film 195B is a film (conductive film) in which a conductive mesh layer made of copper is formed on a transparent substrate. Usually, this conductive film is manufactured by pasting a copper foil on a transparent substrate and then processing it into a mesh.

  As described above, the conductive gasket 198 is provided on a part of the electromagnetic wave shielding film 195B. The gasket 198 is composed of a cylindrical metal film, a metal mesh, or the like including a cushioning material such as a resin sponge inside. Further, if necessary, a copper tape may be provided between the electromagnetic wave shielding film 195B and the conductive gasket 198 in order to reduce the interface resistance. Further, a metal leaf spring-like member can be used instead of the gasket 198.

(Antireflection film 195A)
The antireflection film 195A is installed when necessary to reduce the reflection of an image of an object or a person arranged around the plasma display device such as a fluorescent lamp or a viewer. The antireflection film 195A may have any configuration as long as this purpose is achieved.

  The antireflection film 195A may be composed of, for example, a transparent substrate and an antireflection layer.

  For the transparent substrate, for example, a transparent resin film or the like is used. Examples of the material for the transparent resin film include polyester resins such as polyethylene terephthalate and polybrylene terephthalate, cellulose resins such as triacetyl cellulose, acrylic resins, and polycarbonate resins. Among these, polyethylene terephthalate and triacetyl cellulose are particularly preferable from the viewpoints of transparency and ease of processing.

  The thickness of the transparent substrate may be, for example, in the range of 10 μm to 500 μm, particularly preferably in the range of 30 μm to 300 μm, and more preferably in the range of 50 μm to 200 μm. By setting the thickness of the transparent substrate to 10 μm or more, the antireflection film 195A is hardly damaged. On the other hand, when the thickness is 500 μm or less, the processing becomes easy and the visible light transmittance of the transparent substrate can be increased.

  On the other hand, the antireflection layer is a laminate in which an inorganic compound having a low refractive index and an inorganic compound having a high refractive index are alternately laminated, a layer made of an inorganic compound having a low refractive index, or a layer made of a resin having a low refractive index. Consists of.

  Examples of the resin having a low refractive index include a fluororesin, a silicone resin, and a fluorosilicone resin. Examples of the inorganic compound having a low refractive index include silicon dioxide. In particular, it is preferable to use an antireflection layer in which a low refractive index material made of a fluoropolymer is formed on one side of a polyethylene terephthalate film. Examples of such products include Asahi Glass Co., Ltd. trade name: Arc Top (URP2199) and Nippon Oil & Fats Co., Ltd. trade names: Realik (RLX1000, RLX4000, RL7800, RL9100).

  Here, the low refractive index means a case where the refractive index is 1.1 to 1.6, but the refractive index is particularly preferably 1.2 to 1.5, and preferably 1.3 to 1. 48 is more preferable.

  In place of the antireflection film, an antiglare film (antiglare film) for reducing reflection due to reflection of visible light may be provided. As an anti-glare film, the brand name: Rialc (RL5500) by Nippon Oil & Fats Corporation etc. are mentioned, for example.

(Ceramic layer 196)
As described above, the ceramic layer 196 is installed in order to further improve the design and decoration of the filter substrate 115.

  The ceramic layer 196 is disposed on the back surface 118B of the glass substrate 118, for example, along the peripheral edge.

  The thickness of the ceramic layer 196 is not particularly limited. The thickness of the ceramic layer 196 may be, for example, in the range of 5 μm to 25 μm.

  Usually, the ceramic layer 196 is composed of ceramic particles. The ceramic particles are composed of a glass composition and a heat resistant pigment. Moreover, the ceramic particles may further contain a refractory filler, if necessary.

  The ceramic layer 196 is installed on the peripheral portion of the back surface 118B of the glass substrate 118 by, for example, screen printing of ink. The ink is prepared, for example, by mixing and dispersing a solid component of ceramic particles including a glass composition, a heat resistant pigment, and a refractory filler in an organic vehicle. Thereafter, the ink is heat-treated, and the ceramic layer 196 is baked on the glass substrate 118.

(Near-infrared absorbing film)
In addition, a near-infrared absorbing film may be provided on the front surface 118A or the back surface 118B of the glass substrate 118.

  The near infrared absorbing film has a transparent substrate and a near infrared absorbing layer. Examples of the material for the transparent substrate include polyester resins such as polyethylene terephthalate and polybrylene terephthalate, cellulose resins such as triacetyl cellulose, acrylic resins, and polycarbonate resins. Among these, polyethylene terephthalate and triacetyl cellulose are particularly preferable from the viewpoints of transparency and ease of processing.

  The thickness of the transparent substrate is preferably 10 μm to 500 μm, more preferably 30 μm to 300 μm, and further preferably 50 μm to 200 μm. By setting the thickness of the transparent substrate to 10 μm or more, the near-infrared absorbing film is hardly damaged. By making the thickness 500 μm or less, processing becomes easy and the visible light transmittance of the transparent substrate can be increased.

  The near-infrared absorbing layer is formed by using an acrylic resin or the like as a binder resin and containing a near-infrared absorbing dye in the binder resin. Examples of the near-infrared absorbing dye include diimonium dyes, phthalocyanine dyes, dithiol complex dyes, squarylium dyes, and tungsten oxide dyes.

(Adhesive layer)
In addition, an adhesive layer may be further provided between the filter substrate 115 and the display panel 130. Thereby, the filter substrate 115 can be more firmly held in the apparatus 100.

  This adhesive layer has optical characteristics (transmittance, refractive index, etc.) equivalent to those of the glass substrate 118.

  In a normal case, the adhesive layer is composed of a light (visible light, ultraviolet ray, etc.) curable resin composition. One example of the photo-curing resin is one or more polymers selected from polyurethane acrylate, polyisoprene acrylate or esterified products thereof, terpene hydrogenated resins, and butadiene polymers, and isobornyl acrylate, dicyclohexane. It is a resin composition having one or more acrylate monomers selected from pentenyloxyethyl methacrylate and 2-hydroxybutyl methacrylate, and a photopolymerization initiator.

  Heretofore, an example of the plasma display device according to the present invention has been described.
