[0011] Below, embodiments will be described with reference to the drawings etc. However, the present disclosure can be implemented in many different forms and is not limited to the description of the embodiments exemplified below. Furthermore, to clarify the explanation, the drawings may show the width, thickness, and shape of each part schematically compared to the actual form, but this is merely an example and should not be construed as limiting.

[0012] In this specification, when expressing an aspect in which another component is placed on top of another component, the term "above" or "below" is used, unless otherwise specified, and includes both a case in which another component is placed directly above or below a component so as to be in contact with the component, and a case in which another component is placed above or below a component with another component in between.

[0013] Furthermore, in this specification, when expressing the manner in which another component is placed on the surface of a component, the terms "on the surface" or "toward the surface" are used, unless otherwise specified, and include both cases in which another component is placed directly above or below the surface of a component so as to be in contact with the surface, and cases in which another component is placed above or below the surface of a component with another component interposed between them.

[0014] The decorative panel, decorative panel assembly, and decorative sheet according to the present disclosure will be described in detail below.

[0015] A.Decorative panel Fig. 1(a) is a schematic front view illustrating a decorative panel according to the present disclosure. Fig. 1(b) is a schematic front view of the decorative panel shown in Fig. 1(a) from which the decorative sheet is omitted. Fig. 1(c) is a cross-sectional view taken along line AA in Fig. 1(a), and Fig. 1(d) is a cross-sectional view taken along line AA in Fig. 1(b).

[0016] As shown in FIGS. 1(a) to 1(d), the decorative panel 100 includes a decorative sheet 10, a display device 20, and a panel member 30. The display device 20 has a first surface S1, which is a display surface. Note that the display device 20 in FIG. 1(b) is in an off state, and no image is displayed on the display surface (first surface S1). The panel member 30 is disposed so as to surround the outer edge of the display device 20. The panel member 30 also has a second surface S2. The display device 20 and the panel member 30 are disposed so that the first surface S1 and the second surface S2 form the same surface. In other words, the display device 20 is incorporated into the panel member 30. The decorative sheet 10 is disposed so as to cover the first surface S1 and the second surface S2.

[0017] FIG. 2(a) shows the display device 20 in an on state, with a predetermined image displayed on the display surface (first surface S1) of the display device 20. As shown in FIG. 2(b), the displayed image can be viewed through the decorative sheet 10. Note that, in this disclosure, an image refers to any image displayed on the display surface of a display device, and may be a still image or a moving image. On the other hand, FIG. 2(c) shows the display device 20 in an off state, with no image displayed on the display surface (first surface S1) of the display device 20, and the color of the display surface is typically black. In this case, as shown in FIG. 2(d), the display device 20 cannot be viewed through the decorative sheet 10, and only the design of the decorative sheet 10 can be viewed.

[0018] In this way, when the display device is in the on state, a predetermined image is visible through the decorative sheet, and when the display device is in the off state, the display device is not visible through the decorative sheet. Therefore, the display device in the off state does not disrupt the harmony of the design with the surrounding environment, and the decorative panel has a luxurious feel.

[0019] 3 is a schematic perspective view illustrating a decorative sheet according to the present disclosure. The decorative sheet 10 shown in FIG. T In this case, from the display device 20 side (the panel member side, not shown), an adhesive layer 4, a shielding layer 3, a base material layer 1, and a design layer 2 are provided in this order. T 4(a) and 4(b), the outer edge of the display device 20 is defined as an outer edge O1, and the outer edge of the opening 3a of the shielding layer 3 is defined as an outer edge O2. 3a In FIG. 4(b), for convenience, the shielding layer 3 is shown as colorless. In the present disclosure, the outer edge O of the opening 3a 3a is aligned with the outer edge O1 of the display device 20 or is positioned inside the outer edge O1 of the display device 20. Furthermore, the shielding layer 3 shields 90% or more of the entire circumference of the outer edge O1 of the display device 20.

[0020] According to the present disclosure, a decorative panel with excellent design is obtained by providing a shielding layer with an opening in a decorative sheet. Furthermore, since the outer edge of the opening in the shielding layer is aligned with the outer edge of the display device or is positioned inside the outer edge of the display device, the boundary between the panel member and the display device can be prevented from being visible, resulting in a decorative panel with excellent design.

[0021] As described above, in a decorative panel in which a display device is incorporated into a panel member and then decorated with a decorative sheet, the display device in the off state is easily visible when the decorative panel is observed from the decorative sheet side, which can degrade the design of the decorative panel. For example, as shown in FIG. 5(a), a panel member 30 is prepared in which a display device 20 is incorporated. When a conventional decorative sheet 70 is attached to the panel member 30 and the display device 20 as shown in FIG. 5(b), the display device 20 in the off state is easily visible. Specifically, even when the display device 20 is in the off state, the display device 20 is visible through the decorative sheet 70, which degrades the design of the decorative panel 300. This is because the conventional decorative sheet 70 is light-transmitting enough to allow the image displayed on the display device 20 to be visible. Therefore, when a viewer observes the decorative panel 300 from the decorative sheet 70 side, the reflected light reaching the viewer is significantly affected by the substrate (the panel member 30 and the display device 20).

[0022] In contrast, the decorative sheet of the present disclosure includes a shielding layer with an opening. Providing the shielding layer on the decorative sheet reduces the influence of the underlying panel member, thereby reducing restrictions on the color of the panel member and broadening the range of materials that can be selected for the panel member. Furthermore, for example, by adjusting the optical density of the shielding layer, the visual difference between the opening region (the region where the display device is located) and the region other than the opening can be reduced, making it difficult for the display device in the off state to be seen, resulting in a decorative panel with good design.

[0023] Furthermore, in particular, in a decorative panel in which a display device is incorporated into a panel member (a decorative panel in which the first surface of the display device and the second surface of the panel member are arranged flush with each other), a boundary occurs between the panel member and the display device because different members, the panel member and the display device, are used in combination. Although the physical gap caused by the boundary is small, humans have a relatively high spatial resolution, so they perceive a large visual gap. In contrast, in the present disclosure, as shown in FIG. 4(b) above, the outer edge O of the opening 3a 3ais aligned with the outer edge O1 of the display device 20 or is positioned inside the outer edge O1 of the display device 20. Furthermore, the shielding layer 3 shields 90% or more of the entire periphery of the outer edge O1 of the display device 20. This prevents the boundary between the panel member 30 and the display device 20 from being visible, resulting in a decorative panel with excellent design.

[0024] 1.Decorative sheet The decorative sheet of the present disclosure has, in the thickness direction, an adhesive layer, a shielding layer, and a design layer, in this order from the panel member side. The decorative sheet also has a base layer between the shielding layer and the design layer, or on the opposite side of the design layer from the shielding layer. For example, the decorative sheet 10 shown in FIG. 6 has, from the panel member 30 side, an adhesive layer 4, a shielding layer 3, a base layer 1, and a design layer 2, in this order. Furthermore, as shown in FIG. 10 (described later), the decorative sheet 10 may also have other layers, such as a light-shielding film 5, a protective layer 6, a resin film layer 7, and an interlayer adhesive layer 8.

[0025] (1) Shielding layer As shown in Fig. 6, the shielding layer 3 is a layer disposed between the adhesive layer 4 and the design layer 2. The shielding layer 3 has an opening 3a at a position overlapping with the display device 20. T From this viewpoint, the region where the shielding layer 3 exists may be referred to as the shielding portion 3b.

[0026] As shown in FIG. 4(b), the outer edge O of the opening 3a in the shielding layer 3 3a is aligned with the outer edge O1 of the display device 20 or is positioned inside the outer edge O1 of the display device 20. In other words, the shielding layer 3 is positioned so as to shield the outer edge O1 of the display device 20. The shielding layer 3 usually shields 90% or more of the entire circumference of the outer edge O1 of the display device 20. The above proportion may be 95% or more, 98% or more, or even 100%.

[0027] As shown in FIG. 4(b), the outer edge O of the opening 3a in the shielding layer 3 3aPreferably, the opening 3a coincides with the outer edge O2 of the effective display area 21 on the first surface S1 or is located outside the outer edge O2 of the effective display area 21. In other words, the opening 3a is preferably located so as not to overlap with the area inside the outer edge O2 of the effective display area 21. The opening 3a may expose 50% or more of the entire periphery of the outer edge O2 of the effective display area 21. The above proportion may be 70% or more, 90% or more, or even 100%.

[0028] The shielding layer 3 contains, for example, a black pigment and a binder resin. Examples of black pigments include carbon black and titanium black. Examples of binder resins include acrylic resin, styrene resin, polyester resin, urethane resin, ketone resin, epoxy resin, melamine resin, fluororesin, and silicone resin.

[0029] The optical density (OD value) of the shielding layer is not particularly limited, but is, for example, 2 or more and 4 or less. As shown in FIG. 8 , the shielding layer 3 has an opening 3a and a shielding portion 3b located outside the opening 3a. Between the opening 3a and the shielding portion 3b, a sloped portion 3c may be provided, in which the optical density slopes from the opening 3a toward the shielding portion 3b. The sloped optical density is adjusted in consideration of the design of the decorative sheet, so that the visual difference between the display surface (first surface) and the second surface of the display device in the off state is minimized when the decorative sheet is used to cover them. Specifically, the optical density is increased or decreased from the opening 3a toward the shielding portion 3b to minimize the visual difference. The sloped portion 3c can have a sloped optical density, for example, by changing the dot density.

[0030] The thickness of the shielding layer is not particularly limited, but may be, for example, 1 μm or more and 20 μm or less, or 2 μm or more and 15 μm or less. If the thickness of the shielding layer is too small, a sufficient shielding effect may not be obtained, and if the thickness of the shielding layer is too large, a large thickness gap may occur between the region where the shielding layer is present and the region of the opening where the shielding layer is not present, which may reduce the design.

[0031] (2)Adhesive layer The adhesive layer in the present disclosure is a layer containing an adhesive. The decorative sheet is bonded to the first surface of the display device and the second surface of the panel member via the adhesive layer.

[0032] Examples of the pressure-sensitive adhesive include acrylic pressure-sensitive adhesives, epoxy pressure-sensitive adhesives, olefin pressure-sensitive adhesives, urethane pressure-sensitive adhesives, silicone pressure-sensitive adhesives, and rubber pressure-sensitive adhesives. Examples of the acrylic pressure-sensitive adhesive include pressure-sensitive adhesives whose main component is a polymer of an acrylic monomer such as an acrylic acid ester or a methacrylic acid ester.

[0033] The adhesive layer is usually transparent. In the present disclosure, "transparent" means that the visible light transmittance is 50% or more, preferably 80% or more. Visible light transmittance refers to the light transmittance in the visible light range, and is specified as the average value of the transmittance at each wavelength when measured using a spectrophotometer (for example, Shimadzu Corporation's "UV-3100PC", compliant with JIS K 0115) at a measurement wavelength of 380 nm or more and 780 nm or less at an incident angle of 0° every 1 nm. The "transparent" of not only the adhesive layer but also each layer described below is defined as above.

[0034] The thickness of the adhesive layer is not particularly limited. T From this perspective, the thickness of the shielding layer 3 is t3, the thickness of the adhesive layer 4 at the position overlapping with the opening 3a of the shielding layer 3 is the first thickness t41, and the thickness of the adhesive layer 4 at the position overlapping with the shielding portion 3b of the shielding layer 3 is the second thickness t42.

[0035] The first thickness t41 is preferably larger than the thickness t3 of the shielding layer 3. As described above, by providing a shielding layer on the decorative sheet, it is possible to make the display device in the off state less visible. On the other hand, as shown in FIG. 7, by providing the shielding layer 3 on the decorative sheet 10, a thickness gap occurs between the shielding portion 3b and the opening 3a. The thickness gap is different from the boundary between the panel member 30 and the display device 20 described above, and is formed at the outer edge O of the opening 3a. 3aHowever, by making the first thickness t41 of the adhesive layer 4 larger than the thickness t3 of the shielding layer 3, the thickness gap caused by the shielding layer 3 can be alleviated, resulting in a decorative panel with better design.

[0036] The difference between the first thickness t41 and the thickness t3 may be, for example, 1 μm or more and 499 μm or less, or 10 μm or more and 100 μm or less. The first thickness t41 may be, for example, 10 μm or more and 500 μm or less, or 20 μm or more and 200 μm or less. The second thickness t42 may be, for example, 1 μm or more and 499 μm or less, or 20 μm or more and 200 μm or less. The first thickness and second thickness of the adhesive layer are determined by observing a cross-sectional image of the adhesive layer and measuring the thickness at 10 points, and averaging the thickness values.

[0037] (3) Design layer The design layer in the present disclosure is a layer that imparts design to the decorative panel.

[0038] The design layer preferably has a picture layer. Examples of the pattern of the picture layer include organic patterns, inorganic patterns, and abstract patterns. Organic patterns refer to patterns derived from the life activities of living organisms such as animals and plants. Inorganic patterns refer to patterns that do not fall under the category of organic patterns. Abstract patterns refer to patterns that interpret objects (e.g., images found in nature) abstractly and do not represent a clear shape. Examples of organic patterns include wood grain patterns, leather patterns, floral patterns, and botanical patterns. Examples of inorganic patterns include stone patterns, marble patterns, concrete patterns, sand patterns, fabric patterns, metal patterns, tile patterns, and brickwork patterns. Examples of abstract patterns include flickering patterns (e.g., ink flickering patterns), smoke patterns, and marble patterns. The design layer may also have a base layer in addition to the picture layer. The base layer is usually located closer to the shielding layer than the picture layer.

[0039] The design layer contains, for example, a colorant and a binder resin. Examples of colorants include inorganic pigments such as carbon black, titanium white, zinc oxide, red iron oxide, Prussian blue, and cadmium red; organic pigments such as azo pigments, lake pigments, anthraquinone pigments, quinacridone pigments, phthalocyanine pigments, isoindolinone pigments, and dioxazine pigments; metal powder pigments such as aluminum powder and bronze powder; pearlescent pigments such as titanium oxide-coated mica and bismuth oxide chloride; fluorescent pigments; and luminous pigments. Dyes may also be used as colorants. The binder resin is similar to the binder resin used in the shielding layer described above. The thickness of the design layer is not particularly limited, but is, for example, 1 μm or more and 20 μm or less.

[0040] As shown in Figure 9(a), the design layer 2 may be a solid layer. For example, by making the thickness of the design layer 2 sufficiently small, the decorative sheet 10 will have sufficient light transmittance. When the design layer 2 is a solid layer, there is an advantage that the design layer 2 is easy to fabricate. On the other hand, when light emitted from a display device (not shown) passes through the design layer 2, it is affected by the color of the design layer 2, so the clarity of the image will be somewhat reduced.

[0041] As shown in Fig. 9(b), the decorative sheet 10 may have a light-shielding film 5 between the shielding layer 3 and the design layer 2. In Fig. 9(b), the light-shielding film 5 is disposed between the base layer 1 and the design layer 2. The design layer 2 is formed in the thickness direction D T On the other hand, the light-shielding film 5 has a plurality of first holes H1 penetrating the design layer 2 in the thickness direction D T The light-shielding film 5 has a plurality of second holes H2 penetrating the light-shielding film 5 in the thickness direction D. T From the viewpoint of the thickness direction D, the first hole H1 and the second hole H2 are arranged so as to overlap. Light emitted from a display device (not shown) passes through the first hole H1 and the second hole H2 and reaches the viewer without being affected by the color of the design layer 2. This has the advantage of providing very high image clarity. Also, as shown in FIG. 9(b), TIn view of this, it is preferable that the first holes H1 and the second holes H2 are also arranged in the region overlapping with the shielding layer 3. This is because a decorative sheet 10 with a more unified design can be obtained.

[0042] The light-shielding film 5 contains, for example, a black pigment and a binder resin. The black pigment and the binder resin are the same as the binder resin used in the above-mentioned shielding layer. The first hole portion H1 and the second hole portion H2 can be formed, for example, by irradiating them with laser light.

[0043] (4) Base material layer The substrate layer in the present disclosure is a layer that supports the design layer and is usually transparent. The substrate layer preferably contains a resin. Examples of the resin include polymethyl methacrylate, polyethylene terephthalate, polyethylene naphthalate, polycarbonate, polystyrene, cyclic polyolefin, ABS (acrylonitrile-butadiene-styrene copolymer), and MABS (methyl methacrylate-acrylonitrile-butadiene-styrene copolymer). The substrate layer may contain one type of resin or two or more types of resin. The substrate layer may have a single layer structure or a laminate structure.

[0044] As shown in Figures 9(a) and (b), the base layer 1 may be disposed between the shielding layer 3 and the design layer 2. On the other hand, as shown in Figures 9(c) and (d), the base layer 1 may be disposed on the opposite side of the design layer 2 from the shielding layer 3. The resin film layer 7 and interlayer adhesive layer 8 shown in Figures 9(c) and (d) will be described later. The thickness of the base layer is not particularly limited, but may be, for example, 30 µm or more and 300 µm or less, or 50 µm or more and 250 µm or less.

[0045] (5) Other layers As shown in FIG. 10 , the decorative sheet 10 may have a protective layer 6 that protects the design layer 2. The provision of the protective layer 6 improves the durability of the decorative sheet 10. The protective layer 6 is disposed on the opposite side of the design layer 2 from the shielding layer 3. The protective layer 6 may be the outermost layer of the decorative sheet 10. The protective layer 6 is usually transparent. The protective layer 6 preferably contains a resin. Examples of such resins include polymethyl methacrylate resin, cellulose resin, fluororesin, silicone resin, olefin resin, urethane resin, nylon resin, and epoxy resin. The protective layer 6 may contain one type of resin or two or more types of resin. The thickness of the protective layer 6 is not particularly limited and is appropriately set depending on the application of the decorative panel. A concave-convex structure (e.g., an embossed structure) may be formed on the surface of the protective layer 6 opposite the design layer 2.

[0046] As shown in FIG. 10 , the decorative sheet 10 may have a resin film layer 7 between the shielding layer 3 and the design layer 2. Alternatively, as shown in FIG. 10 , a substrate layer 1 may be disposed between the shielding layer 3 and the design layer 2, and a resin film layer 7 may be disposed between the shielding layer 3 and the substrate layer 1. Providing the resin film layer 7 provides the decorative sheet 10 with appropriate stiffness. Examples of resins used for the resin film layer 7 include polycarbonate, polymethyl methacrylate, polyethylene terephthalate, polyethylene naphthalate, polystyrene, cyclic polyolefin, ABS, and MABS. The resin film layer 7 may contain one type of resin or two or more types of resins. The thickness of the resin film layer 7 is not particularly limited, but may be the thickest of all the layers constituting the decorative sheet. The thickness of the resin film layer 7 may be, for example, 50 μm or more and 1.0 mm or less, or 100 μm or more and 750 μm or less.

[0047] 10, the decorative sheet 10 may have an interlayer adhesive layer 8 that improves adhesion between one layer and another layer. The material of the interlayer adhesive layer 8 is the same as the material of the adhesive layer 4 described above. The thickness of the interlayer adhesive layer 8 is not particularly limited and may be set appropriately depending on the application of the decorative panel.

[0048] When the decorative sheet has a high gloss, a decorative panel with a luxurious feel is obtained. On the other hand, when the decorative sheet has a high gloss, the boundary between the panel member and the display device is easily visible. In contrast, in the present disclosure, the shielding layer shields the outer edge of the display device, thereby preventing the boundary between the panel member and the display device from being visible. The 60° gloss value of the decorative sheet with respect to the visible surface is, for example, 30 or more, and may be 60 or more.

[0049] 2.Display device The display device according to the present disclosure has a first surface that is a display surface. In addition, in the display device, the surface opposite to the first surface is sometimes referred to as the back surface.

[0050] As shown in FIG. 1(d), the first surface S1 of the display device 20 is preferably flat. That is, it is preferable that the first surface S1 of the display device 20 does not have any convex or concave portions. This is because the first surface and the second surface can easily form the same surface. On the other hand, although not specifically shown, the first surface of the display device may be a curved surface. If the first surface is a curved surface, it is preferable that the second surface is also a curved surface so that they form the same surface.

[0051] The display device may be a touch panel. In this case, the display device can usually be operated by touching it through the decorative sheet. In particular, the decorative panel of the present disclosure has a display device incorporated into the panel member, allowing intuitive operation by touching it. The display device may also have a sound collection unit and be operable by voice. The display device may also have a communication unit and be capable of communicating with an external server. The communication with the external server may be wired or wireless. Examples of display methods for the display device include a liquid crystal display, an organic EL display, a plasma display, and an LED display. The display device may also be, for example, a tablet terminal.

[0052] 3. Panel materials The panel member according to the present disclosure is disposed so as to surround the outer edge of the display device, and has a second surface.

[0053] Fig. 11(a) is a schematic front view illustrating a decorative panel according to the present disclosure. For convenience, the decorative sheet 10 is omitted from Fig. 11(a). Fig. 11(b) is a schematic rear view of the decorative panel shown in Fig. 11(a). Figs. 11(c) to 11(f) are cross-sectional views taken along lines AA, BB, CC, and DD of Fig. 11(a) and Fig. 11(b), respectively.

[0054] As shown in FIGS. 11(a) and 11(b), the panel member 30 is disposed so as to surround the outer edge of the display device 20. The material of the panel portion is not particularly limited, but examples thereof include metal, ceramic, resin, wood, and paper. The panel member 30 shown in FIGS. 11(a) and 11(b) is an integrated member having an opening for placing the display device 20. On the other hand, although not specifically shown, the panel portion may be a member made up of a combination of multiple parts to form the opening.

[0055] As shown in FIGS. 11(a), (b), and (f), the panel member 30 may have a notch 31. The notch 31 is, for example, a portion for pressing a physical switch of the display device 20. Furthermore, as shown in FIGS. 11(a), (b), and (e), the panel member 30 may have a notch 32. The notch 32 is, for example, a portion for attaching a power cord 50 of the display device 20. Although not particularly shown, a notch may be provided in the panel member in order to attach a cable to the display device.

[0056] 11(b) to (f), the decorative panel 100 may have a back member 40 that is disposed on the back side of the display device 20 and limits movement of the display device 20 in the thickness direction (the front-to-back direction of the paper). Providing the back member 40 makes it easier to fix the position of the display device 20. Also, as shown in FIGS. 11(b) and 11(c), the decorative panel 100 may have an adjustment jig 60 that adjusts the relative position of the panel member 30 and the back member 40 in the thickness direction (the front-to-back direction of the paper). By finely adjusting the relative position of the panel member 30 and the back member 40 using the adjustment jig 60, the relative position of the first surface S1 and the second surface S2 can be adjusted.

[0057] As shown in FIG. 11( c), the adjustment jig 60 is in contact with both the panel member 30 and the rear member 40. For example, if the adjustment jig 60 is a screw such as a plunger, the relative position of the panel member 30 and the rear member 40 can be finely adjusted by adjusting the fastening strength of the adjustment jig 60. Specifically, when the fastening strength of the adjustment jig 60 is increased, the display device 20 is pushed out toward the rear member 40, and the first surface S1 of the display device 20 moves toward the decorative sheet 10. Furthermore, when the fastening strength of the adjustment jig 60 is decreased by, for example, physically fixing the display device 20 and the rear member 40 (for example, by fixing with adhesive tape), the display device 20 is pulled back toward the rear member 40, and the first surface S1 of the display device 20 moves to the side opposite the decorative sheet 10.

[0058] As shown in FIG. 11(b), the decorative panel 100 may have multiple adjustment jigs 60. In FIG. 11(b), the multiple adjustment jigs 60 are arranged to sandwich two opposing sides of the display device 20 when viewed in the thickness direction (the front-to-back direction of the page). By using multiple adjustment jigs 60 in this manner, the normal direction of the first surface S1 of the display device 20 can be adjusted with high precision. As a result, the positional relationship between the first surface S1 and the second surface S2 can be adjusted with high precision. Also, in FIG. 11(b), multiple adjustment jigs 60 are arranged along the longitudinal direction of the display device 20. Although not specifically shown, multiple adjustment jigs may also be arranged along the lateral direction of the display device. Furthermore, when the display device is rectangular, one or more adjustment jigs may be arranged on only one side, one or more adjustment jigs may be arranged on each of two or more sides, one or more adjustment jigs may be arranged on each of three or more sides, or one or more adjustment jigs may be arranged on each of all four sides.

[0059] The decorative panel may also have a cushion member that fills any gaps (minor gaps) that may occur between the panel member and the display device. The cushion member is preferably black in color.

[0060] 4.Decorative panels The decorative panel of the present disclosure includes the decorative sheet, the display device, and the panel member described above. The uses of the decorative panel are not particularly limited, and examples thereof include building materials such as doors, shelves, walls, floors, and ceilings; electronic devices such as refrigerators, air conditioners, washing machines, ovens, and microwaves; furniture such as chests of drawers, bookshelves, cupboards, cupboards, desks, chairs, beds, TV stands, dressing tables, and speakers; interior and exterior components of vehicles such as automobiles and trains; partitions; and bulletin boards.

[0061] B. Decorative panel assembly FIG. 12(a) is a schematic front view illustrating a decorative panel assembly according to the present disclosure, and FIG. 12(b) is a schematic front view of the decorative panel assembly shown in FIG. 12(a) from which the decorative sheet is omitted.

[0062] 12(a) and 12(b) includes two types of decorative panels: a first decorative panel 100A and a second decorative panel 100B. In the decorative panel assembly 200, the second decorative panel 100B, the first decorative panel 100A, the second decorative panel 100B, and the second decorative panel 100B are stacked in this order from top to bottom.

[0063] 12(a) and 12(b), the first decorative panel 100A is the decorative panel described above in "A. Decorative Panel." On the other hand, the second decorative panel 100B is a decorative panel that does not correspond to the first decorative panel 100A and is typically a decorative panel that does not have a display device.

[0064] According to the present disclosure, the use of the above-described first decorative panel results in a decorative panel assembly with excellent design. Furthermore, by using two types of decorative panels, the first decorative panel and the second decorative panel, if, for example, the display device of the first decorative panel breaks down, it is possible to replace or repair only the broken first decorative panel in the decorative panel assembly. Since there is no need to replace or repair the entire decorative panel assembly, the cost and effort required for replacement or repair can be reduced.

[0065] 1. First decorative panel The first decorative panel in this disclosure is the same as that described above in "A. Decorative Panel."

[0066] 2. Second decorative panel The second decorative panel in the present disclosure includes a second panel member and a second decorative sheet covering the second panel member. The second decorative panel typically does not include a display device. The second panel member and the second decorative sheet are essentially the same as those described above for the panel member and decorative sheet in "A. Decorative Panel." The panel member and decorative sheet in "A. Decorative Panel" can be referred to as the first panel member and the first decorative sheet, respectively. The elements constituting the first panel member and the first decorative sheet can also be referred to with the prefix "first." For example, an adhesive layer can be referred to as the first adhesive layer.

[0067] It is preferable that the second decorative sheet has a second adhesive layer, a second shielding layer, and a second design layer in that order in the thickness direction, and has a second base material layer between the second shielding layer and the second design layer, or on the opposite side of the second shielding layer relative to the second design layer.

[0068] It is preferable that the design and texture of the second decorative panel and the first decorative panel are unified. This is because a uniform impression is obtained for the entire decorative panel assembly. Therefore, it is preferable that the second decorative panel and the first decorative panel have the same layer structure. Specifically, since the second decorative panel usually does not have a display device, the second design layer of the second decorative sheet does not need to have enough light transparency to allow images displayed on the display device to be visible. On the other hand, in order to obtain a uniform impression for the entire decorative panel assembly, it is preferable that the second design layer of the second decorative sheet and the first design layer of the first decorative sheet are the same layer.

[0069] When the second design layer in the second decorative sheet has the above-mentioned light transmittance, the second decorative sheet preferably has a second shielding layer. In particular, it is preferable that the second shielding layer in the second decorative sheet and the first shielding layer in the first decorative sheet are the same layer. Note that, since the second decorative panel does not have a display device, the second shielding layer in the second decorative sheet, unlike the first shielding layer in the first decorative sheet, does not usually have an opening for exposing the display device. When determining whether they are the "same layer," the presence or absence of an opening is not taken into consideration.

[0070] 3. Decorative panel assembly The decorative panel assembly of the present disclosure includes the first decorative panel and the second decorative panel described above. The decorative panel assembly may include one or more first decorative panels and one or more second decorative panels. Furthermore, it is preferable that the first decorative panel and the second decorative panel are disposed adjacent to each other in the vertical or horizontal direction.

[0071] In adjacent first and second decorative panels, the design of the first decorative panel and the design of the second decorative panel preferably have continuity at the boundary between the first and second decorative panels. This relationship between the adjacent first and second decorative panels creates a uniform impression across the entire decorative panel assembly. For example, in FIG. 12(a), the design of the second decorative sheet 10B in the topmost second decorative panel 100B and the design of the first decorative sheet 10A in the second-lowest first decorative panel 100A are both wood grain patterns. In this case, the wood grain pattern of the second decorative panel 100B is preferably continuous with the wood grain pattern of the first decorative panel 100A across the boundary between the second decorative panel 100B and the first decorative panel 100A.

[0072] The above relationship is preferably satisfied between the design of the first decorative sheet 10A in the first decorative panel 100A located second from the top and the design of the second decorative sheet 10B in the second decorative panel 100B located third from the top in Fig. 12(a).Similarly, the above relationship is preferably satisfied between the design of the second decorative sheet 10B in the second decorative panel 100B located third from the top in Fig. 12(a) and the design of the second decorative sheet 10B in the second decorative panel 100B located bottommost in Fig. 12(a).

[0073] The uses of the decorative panel assembly are the same as those described above in "A. Decorative Panel."
