Abstract

To provide a closet door, and a closet that can suppress recognition of the presence of a video display unit in a non-video display period, and can display a video at a necessary timing.SOLUTION: A closet door 201 comprises: a decorative sheet 202 for covering an opening 305; and a video display unit 206 that is covered by a partial area E of the decorative sheet 202 and displays a video. A video is displayed in the area E of a surface 202a of the decorative sheet 202 in a video display period of the video display unit 206. A video can thus be displayed on the surface 202a of the decorative sheet 202 at a timing when the video is required to be displayed. Meanwhile, a pattern of the decorative sheet 202 is displayed in a non-video display period of the video display unit 206. The video display unit 206 is thus hidden by the pattern in the non-video display period, and the presence of the video display unit 206 is thereby difficult to be recognized. Consequently, in the non-video display period, recognition of the presence of the video display unit 206 can be suppressed, and a video can be displayed at a necessary timing.SELECTED DRAWING: Figure 19

Summary of the Invention

Problems to be Solved by the Invention

[0005] Here, for the purpose of checking various information on the storage door, etc., it may be required to provide a monitor around the storage door. When a monitor as described in Patent Document 1 is adopted around the storage door, only another still image is expressed on the surface of the monitor, and the presence as a monitor remains. Therefore, it is required to suppress the recognition of the presence of a video display unit such as a TV in the space. On the other hand, it is required to display the video of the video display unit at the necessary timing.

[0006] An object of the present invention is to provide a closet door, a closet, an entrance storage door, and an entrance storage that suppress recognition of the presence of a video display unit when the video is not being displayed and can display the video at a necessary timing.

Means for Solving the Problems

[0007] [1] The closet door according to the present invention is, on one side, a closet door provided at an opening of a closet, and includes a decorative sheet for covering the opening and a video display unit covered by a partial region of the decorative sheet and configured to display a video. On the surface of the decorative sheet in the region, the video is displayed when the video display unit displays the video, and the pattern of the decorative sheet is displayed when the video display unit does not display the video.

[0008] On the surface of the decorative sheet in the region, the video is displayed when the video display unit displays the video. Therefore, at a timing when it is necessary to display the video, the video can be displayed on the surface of the decorative sheet. On the other hand, the pattern of the decorative sheet is displayed when the video display unit does not display the video. Therefore, when the video is not being displayed, the video display unit is hidden by the pattern, making it difficult to recognize the presence of the video display unit. From the above, recognition of the presence of the video display unit is suppressed when the video is not being displayed, and the video can be displayed at a necessary timing.

[0009] [2] The closet door of [1] above may further include a transparent substrate that supports the decorative sheet by pasting the decorative sheet. In this case, the decorative sheet can cover the video display unit in a state of high smoothness by being supported by the substrate.

[0010] [3] In the closet door of [1] or [2] above, the video display unit may display the video without operating a remote control. In this case, even in a state where it is difficult to recognize the presence of the video display unit with the decorative sheet, the video display unit can display the video.

[0011] [4] The closet according to the present invention is, on one side, a closet in which at least one of a plurality of closet doors is a closet door of any one of the above [1] to [3] having a video display unit, and the pattern of the decorative sheet of the closet door having the video display unit is the pattern of the other closet doors.

[0012] In this closet, the pattern of the decorative sheet of the closet door having the video display unit is the pattern of the other closet doors. Therefore, the closet door having the video display unit can exist without a sense of incongruity as a series of closet doors.

[0013] [5] In the closet of the above [4], the video display unit may display the contents of the stored items. In this case, the stored items can be easily confirmed from the outside of the closet.

[0014] [6] The closet of the above [4] or [5] may have a storage structure capable of storing information appliances. In this case, it becomes possible to efficiently store information appliances, which are new home appliances of the information and communication system, in the closet. In addition, since the information of the information appliances can also be projected onto the video display unit attached to the closet door, there is no need to open the closet door for confirmation.

[0015] [7] The closet described in any one of the above [4] to [6] may have a waste heat portion for waste heat generated when storing information appliances at least above any one of a plurality of closet doors. In this case, when storing information appliances, it is possible to suppress heat from accumulating inside the closet.

[0016] [8] The closet described in any one of the above [4] to [7] may have a passage portion through which a self-propelled cleaner can pass at least below any one of a plurality of closet doors. In this case, after the cleaning is completed, the self-propelled cleaner can automatically enter the closet through the passage portion. Therefore, the self-propelled cleaner can be automatically stored in the closet.

[0017] [9] The entrance storage door according to the present invention is, on one side, an entrance storage door provided at the opening of the entrance storage, and includes a decorative sheet for covering the opening, and a video display unit covered by a partial area of the decorative sheet for displaying video. In the surface area of the decorative sheet, video is displayed when the video display unit displays video, and the pattern of the decorative sheet is displayed when the video display unit does not display video.

[0018] According to this entrance storage door, the same operations and effects as those of the above-described closet door can be obtained.

[0019]

[10] In the entrance storage door described in [9] above, the video display unit may display any one of weather forecasts and news, personal information, images of people photographed by a camera, and information inside the entrance storage. Thereby, the user can grasp this information at the entrance.

[0020]

[11] The entrance storage according to one aspect of the present invention is, on one side, an entrance storage in which at least one of a plurality of entrance storage doors has a video display unit and is the entrance storage door described in [9] or

[10] , and the pattern of the decorative sheet of the entrance storage door having the video display unit is the pattern of the other entrance storage doors.

[0021] According to this entrance storage, the same operations and effects as those of the above-described closet can be obtained.

Effects of the Invention

[0022] According to the present invention, it is possible to provide a closet door, a closet, an entrance storage door, and an entrance storage that suppress recognition of the presence of the video display unit when the video is not displayed and can display the video at a necessary timing.

Mode for Carrying Out the Invention

[0024] [Regarding Printed Matter] First, with reference to FIGS. 1 to 15, an example of the printed matter used in the present embodiment will be described. However, the content described with reference to FIGS. 1 to 15 is merely an exemplification of what kind of printed matter can be adopted in the present invention. Therefore, the layer structure of the printed matter exemplified in the description with reference to FIGS. 1 to 15 does not limit the layer structure of the printed matter adopted in the present invention. Here, the characteristics of the printed matter when used as a light source will also be described. Therefore, in order to explain the printed matter, FIG. 1 shows the printed matter in a state incorporated in the display device. In this specification, when the printed matter is formed by printing dot-like ink, the layer structure of the printed matter may be such that a part of one layer and a part of another layer are in the same position in the thickness direction, or may penetrate each other. When observed as a plan view, a structure in which a pattern forming one layer and a pattern forming another layer partially overlap and do not overlap in other parts may also be included. Note that each layer in the layer structure of the printed matter can also be regarded as a stack of each printing pattern.

[0025] [Example 1-1] FIG. 1 is a cross-sectional view schematically showing a display device according to the first example. FIG. 2 is a cross-sectional view schematically showing a pattern printing layer provided in the display device shown in FIG. 1. As shown in FIG. 1, the display device 1 includes a printed matter 2 and a light source 3. The printed matter 2 is a sheet for expressing a pattern, and includes a translucent base material 4, a pattern printing layer 5, and a transmissive smoke printing layer 30. The printed matter 2 is provided in front of the light source 3 (between the viewer and the light source 3). The printed matter 2 has total light transmittance. Therefore, when the power of the light source 3 is ON, the viewer can visually recognize the light from the light source 3 that has passed through the printed matter 2, and when the power of the light source 3 is OFF, the viewer can visually recognize the pattern expressed by the printed matter 2. The light source 3 is, for example, a display device.

[0026] The translucent base material 4 is a base material having visible light transmittance. The translucent base material 4 is, for example, made of a resin having transparency. Examples of the resin having transparency include PET, PMMA, polycarbonate, polyethylene, polypropylene, nylon, etc. The translucent base material 4 may be a glass base material. The thickness of the translucent base material 4 is, for example, 25 μm to 250 μm, but a base material having a thickness below or above this range can also be used as long as printing is possible. In the case of a glass base material, it is, for example, about several mm to 10 mm. Note that, if necessary, a surface protection layer may be provided on the surface side (opposite side to the pattern printing layer 5) of the translucent base material 4.

[0027] The pattern printing layer 5 is a layer for expressing the pattern of the printed matter 2. The pattern printing layer 5 includes a first color pattern layer 10 provided on one surface 4a of the translucent base material 4 and a second color pattern layer 20 provided on the first color pattern layer 10.

[0028] The first color pattern layer 10 can be provided on the surface 4a by, for example, screen printing, inkjet printing, gravure printing, or offset printing. As shown in FIG. 2, the first color pattern layer 10 is composed of a plurality of first color dots 11. Here, the "dot" means a point that constitutes a printed image, and its shape is not limited to a circle, and it may be a rectangle, a polygon, or other shapes. Each of the plurality of first color dots 11 includes a first color binder 12 and a plurality of first color pigment chips 13 dispersed inside the first color binder 12. The content rate of the plurality of first color pigment chips 13 is, for example, in the range of 0.5 parts by weight or more and 20 parts by weight or less when the first color binder 12 is 100 parts by weight.

[0029] Examples of the first color binder 12 include vinyl resins, acrylic resins, thermoplastic urethane resins, polyester resins, and polycarbonate resins. The thickness of the first color pattern layer 10 is, for example, 1 μm to 10 μm. Note that a curing agent may be contained in the first color pattern layer 10. In this case, the heat resistance of the first color pattern layer 10 and the adhesion of the first color pattern layer 10 to the light-transmissive substrate 4 can be improved. Further, a weathering agent may be contained in the first color pattern layer 10. As the weathering agent, known ultraviolet absorbers and light stabilizers can be used.

[0030] In the first - 1 example, the plurality of first color pigment chips 13 are a plurality of first interference pigments 14a, 14b that generate different interference lights. Each of the first interference pigments 14a, 14b is composed of a thin sheet (not shown) having visible light transmissibility and a metal oxide film (not shown) covering the thin sheet. Among the incident light from the light-transmissive substrate 4 side to the first color pattern layer 10, the light reflected on the surface of the metal oxide film and the light that passes through the metal oxide film and is reflected on the surface of the thin sheet interfere with each other to generate interference light. By adjusting the film thickness of the metal oxide film and the refractive index of the metal oxide film, interference light having a desired wavelength can be generated.

[0031] In the first example, each of the first interference pigments 14a and 14b is titanium dioxide-coated mica. The particle size range of the titanium dioxide-coated mica includes, for example, a range of 25 μm or more and 60 μm or less. Here, the "particle size" means the longest diameter of the particle cross-section. The flakes constituting the first interference pigments 14a and 14b may be other than mica, and may be, for example, silica, alumina, glass, or poly-silicate. The metal oxide film constituting the first interference pigments 14a and 14b may be other than titanium dioxide, and may be, for example, zirconium oxide, zinc oxide, iron oxide, or tin oxide.

[0032] From each of the first interference pigments 14a and 14b, when incident light E is incident on the first color pattern layer 10, respective first interference lights 15a and 15b different from each other are generated. That is, the wavelengths of the first interference lights 15a and 15b are different from each other. Thereby, the first interference pigments 14a and 14b exhibit color mixing. Each of the first interference pigments 14a and 14b is, for example, a red interference pigment (red pearl pigment) and a gold interference pigment (gold pearl pigment), respectively. In this case, each of the first interference lights 15a and 15b exhibits red and gold, respectively. The respective blending amounts of the first interference pigments 14a and 14b may be the same or different from each other.

[0033] The second color pattern layer 20 can be provided on the first color pattern layer 10 by, for example, screen printing, inkjet printing, gravure printing, or offset printing. As shown in FIG. 2, the second color pattern layer 20 is composed of a plurality of second color dots 21. Here, the "dot" means a point that is an element constituting a printed image, and its shape is not limited to a circular shape, and may be a rectangular shape, a polygonal shape, or other shapes. Each of the plurality of second color dots 21 includes a second color binder 22 and a plurality of second color pigment chips 23 dispersed inside the second color binder 22. The content rate of the plurality of second color pigment chips 23 is, for example, within a range of 0.5 parts by weight or more and 20 parts by weight or less when the second color binder 22 is 100 parts by weight.

[0034] Examples of the binder 22 for the second color include vinyl resins, acrylic resins, thermoplastic urethane resins, polyester resins, polycarbonate resins, and the like. The thickness of the second color pattern layer 20 is, for example, 1 μm to 10 μm. Note that a curing agent may be contained in the second color pattern layer 20. In this case, the heat resistance of the second color pattern layer 20 and the adhesion of the second color pattern layer 20 to the first color pattern layer 10 can be improved. Further, a weathering agent may be contained in the second color pattern layer 20. As the weathering agent, known ultraviolet absorbers and light stabilizers can be used.

[0035] In the first example, the plurality of second color pigment chips 23 are second interference pigments 24 that generate interference light of a single color different from the mixed color indicated by the first interference pigments 14a and 14b. The second interference pigment 24 is composed of a thin sheet having visible light transmissibility (not shown) and a metal oxide film covering the thin sheet (not shown). Among the incident light from the light-transmitting substrate 4 side to the second color pattern layer 20, the light reflected on the surface of the metal oxide film and the light passing through the metal oxide film and reflected on the surface of the thin sheet interfere with each other to generate interference light. By adjusting the film thickness of the metal oxide film and the refractive index of the metal oxide film, interference light having a desired wavelength can be generated.

[0036] In the first example, the second interference pigment 24 is titanium dioxide-coated mica. The particle size range of the titanium dioxide-coated mica includes, for example, a range of 25 μm or more and 60 μm or less. Here, the "particle size" means the longest diameter of the particle cross section. The thin sheet constituting the second interference pigment 24 may be other than mica, and may be, for example, silica, alumina, glass, or poly silicate. The metal oxide film constituting the second interference pigment 24 may be other than titanium dioxide, and may be, for example, zirconium oxide, zinc oxide, iron oxide, or tin oxide.

[0037] From the second interference pigment 24, when incident light E is incident on the second color pattern layer 20, monochromatic second interference light 25 is generated. As a result, the second interference pigment 24 exhibits a single color. The second interference pigment 24 may be an interference pigment that generates second interference light 25 of a single color different from the mixed color shown by the first interference pigments 14a and 14b. For example, it may be a green interference pigment (green pearl pigment). In this case, the second interference light 25 exhibits green.

[0038] The transmissive smoke printing layer 30 has a function of attenuating light from the front side of the viewing point that passes through the printed matter 2. The transmissive smoke printing layer 30 is provided on the outermost surface on the side opposite to the light-transmissive base material 4 with respect to the pattern printing layer 5. In the first example, as shown in FIG. 1, the transmissive smoke printing layer 30 is provided on the second color pattern layer 20. The transmissive smoke printing layer 30 can be provided on the second color pattern layer 20 by, for example, screen printing, inkjet printing, gravure printing, or offset printing using an ink in which a small amount of carbon black is dispersed in a resin binder such as vinyl, acrylic, urethane, or polyester. The thickness of the transmissive smoke printing layer 30 is, for example, 1 μm to 10 μm. Note that a curing agent may be contained in the transmissive smoke printing layer 30. In this case, the heat resistance of the transmissive smoke printing layer 30 and the adhesion of the transmissive smoke printing layer 30 to the second color pattern layer 20 can be improved. Further, a weathering agent may be contained in the transmissive smoke printing layer 30. As the weathering agent, known ultraviolet absorbers and light stabilizers can be used.

[0039] In the printed matter 2, a pattern is expressed by additive color mixing of the first interference lights 15a and 15b generated by the first interference pigments 14a and 14b and the second interference light 25 generated by the second interference pigment 24.

[0040] The total light transmittance of the printed matter 2 is, for example, 30% to 70%. The total light transmittance here means a value obtained by measuring the total light transmittance using a spectrophotometer (for example, UV-2100, manufactured by Shimadzu Corporation).

[0041] In the printed matter 2 according to the first - 1 example described above, since the first - color pattern layer 10 contains the first interference pigments 14a and 14b and the second - color pattern layer 20 contains the second interference pigment 24, a three - dimensional pattern can be expressed with a small number of printed layers. Further, in the printed matter 2, the pattern layer containing the interference pigments that generate different interference lights is only the first - color pattern layer 10 among the first - color pattern layer 10 and the second - color pattern layer 20. Therefore, the color - matching work and the alignment work during printing can be simplified. Thus, according to the printed matter 2, a three - dimensional pattern can be expressed with a small number of printed layers, and the color - matching work and the alignment work during printing can be simplified.

[0042] In the first - 1 example, the printed matter 2 includes a transmissive smoke - printed layer 30 provided on the second - color pattern layer 20. Thereby, the color - developing property of the first - color pattern layer 10 and the second - color pattern layer 20 becomes more excellent. Further, since the transmissive smoke - printed layer 30 has transmissivity, a decrease in the visibility of the image of the display device 1 is favorably suppressed.

[0043] In the first - 1 example, each of the first interference pigments 14a and 14b and the second interference pigment 24 contains titanium - dioxide - coated mica having a particle size of 25 μm or more and 60 μm or less. When containing titanium - dioxide - coated mica having a particle size of 25 μm or more, the transmissivity and the color - developing property of the pattern - printed layer 5 can be improved. When containing titanium - dioxide - coated mica having a particle size of 60 μm or less, a decrease in the resolution and gradation property of the pattern - printed layer 5 can be suppressed.

[0044] In the first example, the content ratio of the plurality of first-color pigment chips 13 is in the range of 0.5 parts by weight or more and 20 parts by weight or less when the binder 12 for the first color is 100 parts by weight, and the content ratio of the plurality of second-color pigment chips 23 is in the range of 0.5 parts by weight or more and 20 parts by weight or less when the binder for the second color is 100 parts by weight. Since the content ratio of the plurality of first-color pigment chips 13 is in the range of 0.5 parts by weight or more, the pattern of the first-color pattern layer 10 is well represented. Since the content ratio of the plurality of first-color pigment chips 13 is in the range of 20 parts by weight or less, it is possible to suppress a decrease in the coating property and permeability of the first-color pattern layer 10. Similarly, since the content ratio of the plurality of second-color pigment chips 23 is in the range of 0.5 parts by weight or more and 20 parts by weight or less when the binder 22 for the second color is 100 parts by weight, the pattern of the second-color pattern layer 20 is well represented while suppressing a decrease in the coating property and permeability of the second-color pattern layer 20.

[0045] In the first example, the total light transmittance of the printed matter 2 is 30% to 70%. When the total light transmittance is 30% or more, when the printed matter 2 is placed in front of the screen, the pattern printing layer 5 becomes difficult to be visually recognized by the light of the image on the screen, and the image is more clearly visually recognized. When the total light transmittance is 70% or less, even if the screen is black, it is possible to suppress the pattern of the pattern printing layer 5 from looking dark.

[0046] In the first example, the display device 1 includes a printed matter 2 and a light source 3. According to the display device 1, when the light source 3 is not lit, the pattern of the pattern printing layer 5 is visually recognized, and when the light source 3 is lit, the transmitted light (pattern display, video display, etc.) from the light source 3 is visually recognized.

[0047] In the first example, the light source 3 may be a display device. In this case, when the display is not lit, the pattern of the pattern printing layer 5 is visually recognized, and when the display is lit, the transmitted light (pattern display, video display, etc.) from the display is visually recognized.

[0048] As described above, the plurality of interference pigments 14a, 14b, 24 may include pearlescent pigments. That is, the pattern printing layer 5 may include a plurality of different interference pearlescent pigments (interference pigments 14a, 14b, 24). Therefore, the printed matter 2 is a printed matter 2 including a translucent substrate 4 and a pattern printing layer 5, and the pattern printing layer 5 may include a plurality of interference pearlescent pigments. Thereby, the pattern printing layer 5 can perform a three-dimensional expression.

[0049] The pattern printing layer 5 may include a first color pattern layer 10 containing an interference pearlescent pigment and a second color pattern layer 20 containing an interference pearlescent pigment. Thereby, the pattern printing layer 5 can further perform a three-dimensional expression.

[0050] Each of the first color pattern layer 10 and the second color pattern layer 20 may include a plurality of interference pearlescent pigments. Thereby, the pattern printing layer 5 can further perform a three-dimensional expression. For example, the second color pattern layer 20 may include other interference pearlescent pigments in addition to the interference pigment 24.

[0051] The particle diameters of the plurality of interference pearlescent pigments may be different from each other. By including interference pearlescent pigments with large and small particle diameters in this way, a decrease in the permeability of the pattern printing layer 5 is suppressed.

[0052] The particle diameters of the plurality of interference pearlescent pigments may be 25 μm or more and 60 μm or less. In this case, the color development property of the pattern of the pattern printing layer 5 can be made more excellent. Further, a decrease in the permeability of the pattern printing layer 5 more than necessary is suppressed, and when a display device is used, the visibility of the image of the display device can be improved.

[0053] The interference pearlescent pigment may include titanium dioxide-coated mica. In this case, the wavelength of the interference light can be adjusted by adjusting the film thickness of the titanium dioxide film. Further, the luminance sense can be improved by enhancing the smoothness of the mica surface.

[0054] The effect obtained by the pattern printing layer 5 containing a plurality of interference pearl pigments can be obtained not only in the first example but also in the second to sixth examples described later.

[0055] [First - 2 Example] Hereinafter, with reference to FIGS. 3 and 4, the printed matter 2A according to the first - 2 example will be described. In the description of the first - 2 example, the descriptions overlapping with the above - mentioned first - 1 example are omitted, and the parts different from the above - mentioned first - 1 example will be described. That is, within the technically possible range, the descriptions of the first - 1 example may be appropriately used in the first - 2 example.

[0056] FIG. 3 is a cross - sectional view schematically showing the printed matter according to the first - 2 example. FIG. 4 is a cross - sectional view schematically showing the white pattern layer provided in the printed matter shown in FIG. 3. The printed matter 2A includes a translucent base material 4 and a pattern printing layer 5. The printed matter 2A further includes a white pattern layer 40 provided on the second - color pattern layer 20.

[0057] The white pattern layer 40 can be provided on the second - color pattern layer 20, for example, by screen printing, inkjet printing, gravure printing, or offset printing. As shown in FIG. 4, the white pattern layer 40 is composed of a plurality of silver dots 41. Here, the "dot" means a point that constitutes a printed image, and its shape is not limited to a circular shape, and it may be a rectangular shape, a polygonal shape, or other shapes. Each of the plurality of silver dots 41 includes a silver binder 42 and a plurality of silver pigment chips 43 dispersed inside the silver binder 42. The content rate of the plurality of silver pigment chips 43 is, for example, in the range of 0.5 parts by weight or more and 20 parts by weight or less when the silver binder 42 is 100 parts by weight.

[0058] Examples of the silver binder 42 include vinyl resins, acrylic resins, thermoplastic urethane resins, polyester resins, polycarbonate resins, and the like. The thickness of the white pattern layer 40 is, for example, 1 μm to 10 μm. The white pattern layer 40 may contain a curing agent. In this case, the heat resistance of the white pattern layer 40 and the adhesion of the white pattern layer 40 to the second color pattern layer 20 can be improved. Further, the white pattern layer 40 may contain a weathering agent. As the weathering agent, known ultraviolet absorbers and light stabilizers can be used.

[0059] Even with the configuration of the printed matter 2A described above, the same operational effects as those in the first example 1-1 are achieved. Further, in the first example 1-2, it is provided on the second color pattern layer 20 and includes a white pattern layer 40 composed of a plurality of silver dots 41, and each of the plurality of silver dots 41 includes a silver binder 42 and a plurality of silver pigment chips 43 dispersed inside the silver binder 42. Thereby, the color developability of the first color pattern layer 10 and the second color pattern layer 20 is excellent, and the pattern printing layer 5 can have a pattern that gives a whitish impression.

[0060] [First Example 1-3] Hereinafter, with reference to FIG. 5, the printed matter 2B according to the first example 1-3 will be described. In the description of the first example 1-3, descriptions overlapping with those in the first examples 1-1 and 1-2 are omitted, and parts different from those in the first examples 1-1 and 1-2 are described. That is, within the technically possible range, the descriptions of the first examples 1-1 and 1-2 may be appropriately used in the first example 1-3.

[0061] FIG. 5 is a cross-sectional view schematically showing the printed matter according to the first example 1-3. The printed matter 2B includes a translucent base material 4 and a pattern printing layer 5. That is, the printed matter 2B does not include a transmissive smoke printing layer 30 and a white pattern layer 40. Even with the configuration of the printed matter 2B described above, the same operational effects as those in the first example 1-1 are achieved.

[0062] [First Example 1-4] Hereinafter, with reference to FIG. 6, the printed matter 2C according to the first to fourth examples will be described. In the description of the first to fourth examples, descriptions overlapping with the first to third examples will be omitted, and parts different from the first to third examples will be described. That is, within the technically possible range, the descriptions of the first to third examples may be appropriately used for the first to fourth examples.

[0063] FIG. 6 is a cross-sectional view schematically showing the printed matter according to the first to fourth examples. The printed matter 2C includes a light-transmissive base material 4, a pattern printing layer 5, a white pattern layer 40, and a transmissive smoke printing layer 30. The white pattern layer 40 is provided on the second color pattern layer 20, and the transmissive smoke printing layer 30 is provided on the white pattern layer 40. Even with the configuration of the printed matter 2C described above, the same operational effects as those of the first to third examples are achieved.

[0064] The display device and the printed matter according to the present disclosure are not limited to the above-described examples, and various other modifications are possible. For example, the second color pattern layer may include a plurality of colors of first interference pigments that generate different first interference lights, and the first color pattern layer may include a second interference pigment that generates a single-color second interference light different from the mixed color shown by the plurality of first interference pigments. Also, in each of the above examples, the first color pigment chip was a two-color first interference pigment, but the first color pigment chip may be a three-color or more first interference pigment.

[0065] [Second Example] [First Example of the Second] As the printed matter and the display device according to this example, a configuration having the same gist as that shown in FIG. 1 may be adopted. Therefore, in the printed matter and the display device according to this example, the description of the configuration having the same gist as that of the printed matter and the display device of the first example will be omitted. The printed matter and the display device according to the first example of the second adopt the layer configuration shown in FIG. 7 instead of the layer configuration shown in FIG. 2.

[0066] The first interference pigment 14a includes a plurality of first titanium dioxide-coated muscovites 18a in a small particle size grade including a particle size range of 5 μm to 25 μm, and a second titanium dioxide-coated muscovite 18b in a large particle size grade including a particle size range of 25 μm to 40 μm. The first interference pigment 14b includes a plurality of first titanium dioxide-coated muscovites 16a in a small particle size grade including a particle size range of 5 μm to 25 μm, and a plurality of second titanium dioxide-coated muscovites 16b in a large particle size grade including a particle size range of 25 μm to 40 μm. The average particle size (D50) of the first titanium dioxide-coated muscovites 18a, 16a is, for example, about 15 μm, and the average particle size (D50) of the second titanium dioxide-coated muscovites 18b, 16b is, for example, about 25 μm. Accordingly, the average particle size of the first titanium dioxide-coated muscovites 18a, 16a is smaller than the average particle size of the second titanium dioxide-coated muscovites 18b, 16b. The second titanium dioxide-coated muscovites 18b, 16b may include a particle size range of 25 μm to 60 μm. In this case, the average particle size (D50) of the second titanium dioxide-coated muscovites 18b, 16b is, for example, about 35 μm. Each of the plurality of first titanium dioxide-coated muscovites 18a, 16a is arranged so as to fill the gaps between the plurality of second titanium dioxide-coated muscovites 18b, 16b, as shown in FIG. 7. Here, the "particle size" means the longest diameter of the particle cross section.

[0067] When incident light L is incident on the first interference pigments 14a, 14b from each of them, first interference lights 17a, 17b different from each other are generated in the first color pattern layer 10. That is, the wavelengths of the first interference lights 17a, 17b are different from each other. Accordingly, the first interference pigments 14a, 14b exhibit color mixing. Each of the first interference pigments 14a, 14b may be, for example, a red interference pigment (red pearl pigment) and a gold interference pigment (gold pearl pigment), respectively. In this case, each of the first interference lights 17a, 17b exhibits red and gold, respectively. Each of the first interference pigments 14a, 14b may be an interference pigment of other colors. The blending amounts of the first interference pigments 14a, 14b may be the same or different from each other.

[0068] As the second color pattern layer 20, one having the same gist as that shown in the first example may be adopted.

[0069] The second interference pigment 24 includes a plurality of first titanium dioxide-coated micas 25a of a small particle size grade including a particle size range of 5 μm to 25 μm and a second titanium dioxide-coated mica 25b of a large particle size grade including a particle size range of 25 μm to 40 μm. The average particle size (D50) of the first titanium dioxide-coated mica 25a is, for example, about 15 μm, and the average particle size (D50) of the second titanium dioxide-coated mica 25b is, for example, about 25 μm. Thus, the average particle size of the first titanium dioxide-coated mica 25a is smaller than the average particle size of the second titanium dioxide-coated mica 25b. The second titanium dioxide-coated mica 25b may include a particle size range of 25 μm to 60 μm. In this case, the average particle size (D50) of the second titanium dioxide-coated mica 25b is, for example, about 35 μm. Each of the plurality of first titanium dioxide-coated micas 25a is arranged so as to fill the gaps between the plurality of second titanium dioxide-coated micas 25b. Here, the "particle size" means the longest diameter of the particle cross-section.

[0070] From the second interference pigment 24, when incident light L is incident on the second color pattern layer 20, monochromatic second interference light 26 is generated. Thereby, the second interference pigment 24 exhibits a single color. The second interference pigment 24 may be an interference pigment that generates monochromatic second interference light 26 different from the mixed colors exhibited by the first interference pigments 14a and 14b. For example, it may be a green interference pigment (green pearl pigment). In this case, the second interference light 26 exhibits green. Note that the second interference pigment 24 may be an interference pigment of a color other than green.

[0071] The transmissive smoke printing layer 30 is a layer for attenuating light that passes through the printed matter 2. The transmissive smoke printing layer 30 is provided on the outermost surface on the side opposite to the light-transmissive base material 4 with respect to the pattern printing layer 5. In the first example, the transmissive smoke printing layer 30 is provided on the second color pattern layer 20 as shown in FIG. 1. The transmissive smoke printing layer 30 can be provided on the second color pattern layer 20 by, for example, screen printing, inkjet printing, gravure printing, or offset printing using an ink in which a small amount of carbon black is dispersed in a resin binder such as vinyl, acrylic, urethane, or polyester. The thickness of the transmissive smoke printing layer 30 is, for example, 1 μm to 10 μm. Note that a curing agent may be contained in the transmissive smoke printing layer 30. In this case, the heat resistance of the transmissive smoke printing layer 30 and the adhesion of the transmissive smoke printing layer 30 to the second color pattern layer 20 can be improved. Further, a weathering agent may be contained in the transmissive smoke printing layer 30. As the weathering agent, known ultraviolet absorbers or light stabilizers can be used.

[0072] In the printed matter 2, the pattern is expressed by additive color mixing of the first interference lights 17a and 17b generated by the first interference pigments 14a and 14b and the second interference light 26 generated by the second interference pigment 24.

[0073] The total light transmittance of the printed matter 2 is, for example, 30% to 70%. The total light transmittance referred to here means a value obtained by measuring the total light transmittance using a spectrophotometer (for example, spectrophotometer UV-2100 manufactured by Shimadzu Corporation).

[0074] In the printed matter 2 according to the second - 1 example described above, in the first - color pattern layer 10, each of the plurality of first titanium - dioxide - coated muscovites 18a, 16a of a small - particle - size grade including a particle - size range of 5 μm to 25 μm is arranged so as to fill the gaps between the plurality of second titanium - dioxide - coated muscovites 18b, 16b of a large - particle - size grade including a particle - size range of 25 μm to 40 μm. In the printed matter 2, in the second - color pattern layer 20, each of the plurality of first titanium - dioxide - coated muscovites 25a of a small - particle - size grade including a particle - size range of 5 μm to 25 μm is arranged so as to fill the gaps between the plurality of second titanium - dioxide - coated muscovites 25b of a large - particle - size grade including a particle - size range of 25 μm to 40 μm. Therefore, according to the printed matter 2, a pattern excellent in visibility and color - developing property can be provided. Further, in the printed matter 2, in the first - color pattern layer 10, by including the second titanium - dioxide - coated muscovites 18b, 16b of a large - particle - size grade, and in the second - color pattern layer 20, by including the second titanium - dioxide - coated muscovite 25b of a large - particle - size grade, a decrease in the transparency of the pattern - printing layer 5 is suppressed. Therefore, according to the printed matter 2, when the power is turned on, a decrease in the visibility of the image of the display device is preferably suppressed.

[0075] In the second - 1 example, the second titanium - dioxide - coated muscovites 18b, 16b, 25b of a large - particle - size grade may be configured to include a particle - size range of 25 μm to 60 μm. In this case, the color - developing property of the pattern is more excellent. Also, it is possible to suppress an excessive decrease in the transparency of the pattern - printing layer 5, and when using a display device, the visibility of the image of the display device 1 can be improved.

[0076] In the second - 1 example, the first interference pigments 14a, 14b and the second interference pigment 24 are interference pigments containing titanium - dioxide - coated muscovite. Therefore, by adjusting the film thickness of the titanium - dioxide film, the wavelength of the interference light can be adjusted. Also, by enhancing the smoothness of the mica surface, the luminance sense can be improved.

[0077] Also in the second example, the configurations according to the first - 2 to first - 4 examples in the first example may be adopted.

[0078] In each of the above examples, each of the first interference pigment and the second interference pigment included a plurality of first titanium dioxide-coated micas and a plurality of second titanium dioxide-coated micas. However, at least one of the first interference pigment and the second interference pigment may include a plurality of first titanium dioxide-coated micas and a plurality of second titanium dioxide-coated micas. Further, in each of the above examples, the first color pigment chip was a two-color first interference pigment, but the first color pigment chip may be a first interference pigment of three or more colors. Further, the first interference pigments of a plurality of colors may be mixed.

[0079] [Experimental Example] Here, an experimental example will be used to explain the tendency of how the image on the liquid crystal monitor and the pattern look depending on the particle size of the titanium dioxide-coated mica contained in the pattern printing layer. As shown in FIG. 8 and Experimental Examples 1 to 3 described later, a printed matter with the particle size of the titanium dioxide-coated mica adjusted was produced. FIG. 8 is a chart showing the configuration of the printed matters according to Experimental Examples 1 to 3. A liquid crystal monitor was installed on the back side (the side of the transmissive smoke printing layer) of the printed matters according to Experimental Examples 1 to 3. The distance between the printed matter and the liquid crystal monitor was set to 2 mm. The visibility (Items 1 to 4 described later) of the liquid crystal monitor in the on state and the off state was evaluated. For Items 1 to 4, a sensory evaluation was performed by four people, and the average score was calculated.

[0080] [Experimental Example 1] A printed matter was produced by sequentially providing a first color pattern layer, a second color pattern layer, a white pattern layer, and a transmissive smoke printing layer on a transparent base material that is transparent PET. In Experimental Example 1, an ink containing a first color binder (urethane resin) and a red interference pigment and a gold interference pigment dispersed inside the first color binder was used to form the first color pattern layer by screen printing technology. As the content rates of the red interference pigment and the gold interference pigment, when the first color binder was 100 parts by weight, 8 parts by weight of a red interference pigment having a particle size of 10 to 40 μm, 2 parts by weight of a red interference pigment having a particle size of 5 to 25 μm, 5 parts by weight of a gold interference pigment having a particle size of 10 to 60 μm, and 2 parts by weight of a gold interference pigment having a particle size of 5 to 25 μm were used.

[0081] In Experimental Example 1, an ink containing a binder for the second color (urethane resin) and a green interference pigment dispersed inside the binder for the second color was used to form a second color pattern layer by screen printing technology.

As the content rate of the silver pigment chips, when the binder for silver was 100 parts by weight, 1 part by weight of the silver pigment chips having a particle size of 5 to 25 μm was used. Further, an ink prepared by blending medium ink and black ink at a ratio of 40:1 was used to form a transmissive smoke printing layer by screen printing technology.

[0083] <Experimental Example 2> A printed matter was produced by sequentially providing a first color pattern layer, a second color pattern layer, a white pattern layer, and a transmissive smoke printing layer on a transparent base material that is transparent PET. In Experimental Example 2, an ink containing a binder for the first color (urethane resin) and a red interference pigment and a gold interference pigment dispersed inside the binder for the first color was used to form the first color pattern layer by screen printing technology. As the content rates of the red interference pigment and the gold interference pigment, when the binder for the first color was 100 parts by weight, 8 parts by weight of the red interference pigment having a particle size of 10 to 40 μm, 2 parts by weight of the red interference pigment having a particle size of 5 to 25 μm, 5 parts by weight of the gold interference pigment having a particle size of 10 to 60 μm, and 2 parts by weight of the gold interference pigment having a particle size of 5 to 25 μm were used.

[0084] In Experimental Example 2, an ink containing a binder for the second color (urethane resin) and a green interference pigment dispersed inside the binder for the second color was used to form a second color pattern layer by screen printing technology. As the content rate of the green interference pigment, when the binder for the second color was 100 parts by weight, 4 parts by weight of a green interference pigment having a particle size of 10 to 40 μm was used. The red interference pigment, the gold interference pigment, and the green interference pigment are all titanium dioxide-coated mica.

[0085] In Experimental Example 2, an ink containing a binder for silver (urethane resin) and silver pigment chips dispersed inside the binder for silver was used to form a white pattern layer by screen printing technology. As the content rate of the silver pigment chips, when the binder for silver was 100 parts by weight, 1 part by weight of silver pigment chips having a particle size of 5 to 25 μm was used. Furthermore, an ink prepared by mixing medium ink and black ink at a ratio of 40:1 was used to form a transmissive smoke printing layer by screen printing technology.

[0086] <Experimental Example 3> A printed matter was produced by sequentially providing a first color pattern layer, a second color pattern layer, and a transmissive smoke printing layer on a transparent substrate that is transparent PET. In Experimental Example 3, an ink containing a binder for the first color (urethane resin) and a green interference pigment dispersed inside the binder for the first color was used to form a first color pattern layer by screen printing technology. As the content rate of the green interference pigment, when the binder for the first color was 100 parts by weight, 4 parts by weight of a green interference pigment having a particle size of 10 to 40 μm and 1 part by weight of a green interference pigment having a particle size of 5 to 25 μm were used.

[0087] In Experimental Example 3, an ink containing a binder for the second color (urethane resin) and a red interference pigment and a gold interference pigment dispersed inside the binder for the second color was used to form a second color pattern layer by screen printing technology. As the content ratio of the red interference pigment and the gold interference pigment, when the binder for the second color was 100 parts by weight, 8 parts by weight of a red interference pigment having a particle size of 10 to 40 μm and 5 parts by weight of a gold interference pigment having a particle size of 10 to 60 μm were used.

[0088] In Experimental Example 3, a permeable smoke printing layer was formed by screen printing technology using an ink in which medium ink and black ink were blended at a ratio of 40:1.

[0089] <Item 1: Regarding the sharpness of the displayed content> The sharpness of the images and characters displayed on the liquid crystal monitor was evaluated when the power of the liquid crystal monitor was turned on. <Score> 5 points: The presence of the pattern is weak with respect to the images and characters displayed on the liquid crystal monitor, and the images and characters look sharp. 3 points: The presence of the pattern is slightly strong with respect to the images and characters displayed on the liquid crystal monitor, and the pattern slightly covers the images and characters and they look somewhat obscured. 1 point: The presence of the pattern is strong with respect to the images and characters displayed on the liquid crystal monitor, and the pattern covers the images and characters and they look obscured.

[0090] <Item 2: Regarding the brightness of the displayed content> The brightness of the images and characters displayed on the liquid crystal monitor was evaluated when the power of the liquid crystal monitor was turned on. <Score> 5 points: The images and characters displayed on the liquid crystal monitor look bright. 3 points: The images and characters displayed on the liquid crystal monitor look slightly dark. 1 point: The images and characters displayed on the liquid crystal monitor look quite dark.

[0091] <Item 3: Regarding the influence of a black liquid crystal monitor> The influence of the black liquid crystal monitor on the pattern when the power of the liquid crystal monitor was turned off was evaluated. <Rating> 5 points: There is no influence of the black color of the liquid crystal monitor, and the pattern can be clearly seen. 3 points: The influence of the black color of the liquid crystal monitor is slightly noticeable, and the pattern looks slightly darker and duller (slightly higher transparency). 1 point: The influence of the black color of the liquid crystal monitor is noticeable, and the pattern looks quite dark and dull (high transparency).

[0092] <Item 4: Color development of the pattern> The color development of the pattern when the power of the liquid crystal monitor was turned off was evaluated. <Rating> 5 points: The color development of the pattern is good. 3 points: The color development of the pattern is slightly weak, and the color of the pattern looks light (whitish). 1 point: The color development of the pattern is weak, and the color of the pattern looks white.

[0093] The results of the sensory evaluations of Items 1 to 4 for Experimental Examples 1 to 3 are shown in Table 1 below. In addition, those with an evaluation of 3 points or more were judged to be at a level with no practical problems. From Experimental Example 1, it was found that the influence of the black liquid crystal monitor on the pattern is quite low, and the visibility of the pattern tends to be expressed at a sufficiently high level. Also, high evaluation results were obtained for the color development of the pattern and the sharpness and brightness of the video and character displays. On the other hand, from Experimental Examples 2 and 3, it was found that while suppressing the influence of the black liquid crystal monitor on the pattern to a low level, the color development of the pattern and the sharpness and brightness of the video and character displays generally tend to have a good finish.

[0094]

Table 1

[0095] [Third example] [Example 3-1] As the printed matter and the display device according to this example, a configuration having the same gist as that shown in FIG. 1 may be adopted. Therefore, in the printed matter and the display device according to this example, the description of the configuration having the same gist as that of the printed matter and the display device in the first example will be omitted. In the printed matter and the display device according to this example, the layer configuration shown in FIG. 9 is adopted instead of the layer configuration shown in FIG. 2.

[0096] The first color pattern layer 10 can be provided on the surface 4a, for example, by screen printing, inkjet printing, gravure printing, or offset printing. As shown in FIG. 9, the first color pattern layer 10 is composed of a plurality of first color dots 11. Here, the "dot" means a point that is an element constituting a printed image, and its shape is not limited to a circular shape, and may be a rectangular shape, a polygonal shape, or other shapes. Each of the plurality of first color dots 11 includes a first color binder 12 and a plurality of first color pigment chips 13 dispersed inside the first color binder 12. The content ratio of the plurality of first color pigment chips 13 is, for example, in the range of 0.5 parts by weight or more and 20 parts by weight or less when the first color binder 12 is 100 parts by weight. In this case, while the pattern of the first color pattern layer 10 is well expressed, it is possible to suppress a decrease in the coating property and permeability of the first color pattern layer 10.

[0097] In the third - first example, the plurality of first color pigment chips 13 are interference pigments 14 (first interference pigments) that generate interference light of a single color of a predetermined color. The interference pigment 14 is composed of a thin sheet (not shown) having visible light permeability and a metal oxide film (not shown) covering the thin sheet. Among the incident light from the light - transmissive base material 4 side to the first color pattern layer 10, the light reflected on the surface of the metal oxide film and the light passing through the metal oxide film and reflected on the surface of the thin sheet interfere with each other to generate interference light. By adjusting the film thickness of the metal oxide film and the refractive index of the metal oxide film, interference light having a desired wavelength can be generated.

[0098] When incident light E is incident on the first color pattern layer 10 from the interference pigment 14, single - color interference light 15 (first interference light) is generated. Thereby, the interference pigment 14 exhibits a single color.

[0099] The second color pattern layer 20 can be provided on the first color pattern layer 10 by, for example, screen printing, inkjet printing, gravure printing, or offset printing. As shown in FIG. 9, the second color pattern layer 20 is composed of a plurality of second color dots 21. Here, the "dot" means a point that constitutes a printed image, and its shape is not limited to a circle, and may be a rectangle, a polygon, or other shapes. Each of the plurality of second color dots 21 includes a second color binder 22 and a plurality of second color pigment chips 23 dispersed inside the second color binder 22. When the second color binder 22 is 100 parts by weight, the content rate of the plurality of second color pigment chips 23 is, for example, in the range of 0.5 parts by weight or more and 20 parts by weight or less. It is possible to suppress a decrease in the coating property and permeability of the second color pattern layer 20 while the pattern of the second color pattern layer 20 is well expressed.

[0100] From the interference pigment 24 (second interference pigment), when incident light E is incident on the second color pattern layer 20, monochromatic interference light 25 (second interference light) is generated. Thereby, the interference pigment 24 shows a single color. The interference pigment 24 may be any interference pigment that generates monochromatic interference light 25 different from the color shown by the interference pigment 14.

[0101] The total light transmittance of the printed matter 2 is, for example, 30% to 70%. The total light transmittance here means a value obtained by measuring the total light transmittance using a spectrophotometer (for example, UV-2100, manufactured by Shimadzu Corporation). When the total light transmittance is 30% or more, when the printed matter 2 is placed in front of the screen, the pattern printing layer 5 becomes difficult to be visually recognized by the light of the image on the screen, and the image is more clearly visually recognized. When the total light transmittance is 70% or less, even if the screen is black, it is possible to suppress the pattern of the pattern printing layer 5 from looking dark.

[0102] Next, with reference to FIGS. 10 and 11, the color combination in the pattern printing layer 5 will be described. FIG. 10(a) is a schematic diagram showing the color combination of the pattern printing layer 5. FIG. 10(b) is a schematic diagram showing the color combination of the pattern printing layer 105 according to an example for comparison. FIG. 11 is a schematic diagram showing a specific example of the color combination of the pattern printing layer 5.

[0103] As shown in FIG. 10(a), in the first color pattern layer 10, an interference pigment of a single color "Color A" is included, so that interference light of a single color "Color A" is generated. In the second color pattern layer 20, an interference pigment of a single color "Color B" is included, so that interference light of a single color "Color B" is generated. Color B is a color different from Color A. Therefore, in the printed matter 2, the pattern is expressed by additive color mixing of the interference light of Color A and the interference light of Color B.

[0104] In the example shown in FIG. 11(a), "gold" is adopted as Color A of the first color pattern layer 10, and "red" is adopted as Color B of the second color pattern layer 20. The printed matter 2 may express a wood grain pattern as a pattern by additive color mixing of gold and red. Since the first color pattern layer 10 is gold, a light-based wood grain can be expressed. In this case, the interference pigment 14 shown in FIG. 9 is, for example, a gold interference pigment (gold pearl pigment). The interference light 15 indicates gold. The interference pigment 24 is, for example, a red interference pigment (red pearl pigment). The interference light 25 indicates red.

[0105] In the example shown in FIG. 11(b), "red" is adopted as Color A of the first color pattern layer 10, and "gold" is adopted as Color B of the second color pattern layer 20. The printed matter 2 may express a wood grain pattern as a pattern by additive color mixing of red and gold. Since the first color pattern layer 10 is red, a wood grain with a slightly stronger red tone can be expressed.

[0106] In the example shown in FIG. 11(c), "silver" is adopted as color A of the first color pattern layer 10, and "gold" is adopted as color B of the second color pattern layer 20. The printed matter 2 may express a hairline pattern as a design by additive mixing of silver and gold. Since the second color pattern layer 20 is gold, a normal stainless steel hairline can be adjusted to a gold tone. Note that the interference pigment 14 shown in FIG. 9 is, for example, a silver interference pigment (silver pearl pigment). The interference light 15 indicates silver.

[0107] In the example shown in FIG. 11(d), "silver" is adopted as color A of the first color pattern layer 10, and "red" is adopted as color B of the second color pattern layer 20. The printed matter 2 may express a hairline pattern as a design by additive mixing of silver and red. Since the second color pattern layer 20 is red, a stainless steel hairline can be adjusted to a bronze tone.

[0108] In the example shown in FIG. 11(e), "gold" is adopted as color A of the first color pattern layer 10, and "silver" is adopted as color B of the second color pattern layer 20. The printed matter 2 may express a hairline pattern as a design by additive mixing of gold and silver. Since the first color pattern layer 10 is gold (or a color containing gold), a finish with a more emphasized gold tone can be achieved.

[0109] In the printed matter 2 according to the third - 1 example described above, the first - color pattern layer 10 includes an interference pigment 14 that generates monochromatic interference light 15, and the second - color pattern layer 20 includes an interference pigment 24 that generates monochromatic interference light 25 different from the color indicated by the interference pigment 14. Here, as an example for comparison, as shown in FIG. 10(b), a printed matter 102 is cited in which the first - color pattern layer 10 includes interference pigments of color X and color Y, and the second - color pattern layer 20 includes an interference pigment of color Z. For example, when expressing a pattern as in the configuration of the example for comparison described with reference to FIG. 11, it is necessary to adjust the three colors of X, Y, and Z, which is time - consuming for color - matching work and alignment work during printing. On the other hand, for a pattern that can be expressed with fewer colors as in FIG. 11, like the printed matter 2 according to this example, by limiting the interference pigments included in the first - color pattern layer 10 and the second - color pattern layer 20 to a single color, it becomes possible to express the pattern only by the intensity of the single color. In this way, the color - matching work and alignment work during printing can be simplified. Therefore, according to this printed matter 2, the color - matching work and alignment work during printing can be simplified.

[0110] Also in the third example, the configurations according to the first - 2 to first - 4 examples in the first example may be adopted.

[0111] [Fourth example] [Fourth - 1 example] As the printed matter and the display device according to this example, a configuration having the same gist as that shown in FIG. 1 may be adopted. Therefore, in the printed matter and the display device according to this example, the description of the configuration having the same gist as that of the printed matter and the display device in the first - 1 example is omitted. The printed matter and the display device according to this example adopt the layer configuration shown in FIG. 12 instead of the layer configuration shown in FIG. 2.

[0112] The first color pattern layer 10 can be provided on the surface 4a, for example, by screen printing, inkjet printing, gravure printing, or offset printing. As shown in FIG. 12, the first color pattern layer 10 is composed of a plurality of first color dots 11. Here, the "dot" means a point that constitutes a printing image, and its shape is not limited to a circular shape, and it may be a rectangular shape, a polygonal shape, or other shapes. Each of the plurality of first color dots 11 includes a first color binder 12 and a plurality of first color pigment chips 13 dispersed inside the first color binder 12. When the content of the plurality of first color pigment chips 13 is based on 100 parts by weight of the first color binder 12, it is, for example, in the range of 0.5 parts by weight or more and 20 parts by weight or less. In this case, while the pattern of the first color pattern layer 10 is well expressed, it is possible to suppress a decrease in the film formability and permeability of the first color pattern layer 10.

[0113] In the first example, the plurality of first color pigment chips 13 are interference pigments 14 (second interference pigments) that generate interference light of a single color of a predetermined color. The interference pigment 14 is the same color as any of the interference pigments 24a and 24b (first interference pigments) described later. The interference pigment 14 is composed of a thin sheet (not shown) having visible light transmittance and a metal oxide film (not shown) covering the thin sheet. Among the incident light from the light-transmitting base material 4 side to the first color pattern layer 10, the light reflected on the surface of the metal oxide film and the light that passes through the metal oxide film and is reflected on the surface of the thin sheet interfere with each other to generate interference light. By adjusting the film thickness of the metal oxide film and the refractive index of the metal oxide film, interference light having a desired wavelength can be generated.

[0114] When incident light E is incident on the first color pattern layer 10 from the interference pigment 14, single-color interference light 15 (second interference light) is generated. Thereby, the interference pigment 14 exhibits a single color.

[0115] The second color pattern layer 20 can be provided on the first color pattern layer 10, for example, by screen printing, inkjet printing, gravure printing, or offset printing. As shown in FIG. 12, the second color pattern layer 20 is composed of a plurality of second color dots 21. Here, the "dot" means a point that constitutes a printing image, and its shape is not limited to a circular shape, and may be a rectangular shape, a polygonal shape, or other shapes. Each of the plurality of second color dots 21 includes a second color binder 22 and a plurality of second color pigment chips 23 dispersed inside the second color binder 22. The content rate of the plurality of second color pigment chips 23 is, for example, in the range of 0.5 parts by weight or more and 20 parts by weight or less when the second color binder 22 is 100 parts by weight. It is possible to suppress a decrease in the coating property and permeability of the second color pattern layer 20 while the pattern of the second color pattern layer 20 is well expressed.

[0116] In the example of 4-1, the plurality of second color pigment chips 23 are interference pigments 24a and 24b of a plurality of colors that generate different interference lights. Each of the interference pigments 24a and 24b is composed of a thin sheet (not shown) having visible light permeability and a metal oxide film (not shown) covering the thin sheet. Among the incident light from the light-transmitting base material 4 side to the second color pattern layer 20, the light reflected on the surface of the metal oxide film and the light passing through the metal oxide film and reflected on the surface of the thin sheet interfere with each other to generate interference light. By adjusting the film thickness of the metal oxide film and the refractive index of the metal oxide film, interference light having a desired wavelength can be generated.

[0117] In the example of 4-1, the interference pigments 24a and 24b are titanium dioxide-coated mica. The particle size range of the titanium dioxide-coated mica includes, for example, the range of 25 μm or more and 60 μm or less. Here, the "particle size" means the longest diameter of the particle cross section. The thin sheet constituting the interference pigments 24a and 24b may be other than mica, and may be, for example, silica, alumina, glass, or polysilicate. The metal oxide film constituting the interference pigments 24a and 24b may be other than titanium dioxide, and may be, for example, zirconium oxide, zinc oxide, iron oxide, or tin oxide.

[0118] From each of the interference pigments 24a and 24b, when incident light E is incident on the second color pattern layer 20, different interference lights 125a and 125b (first interference lights) are respectively generated. That is, the wavelengths of the interference lights 125a and 125b are different from each other. Thereby, the interference pigments 24a and 24b exhibit color mixing. The respective blending amounts of the interference pigments 24a and 24b may be the same or different from each other. The interference pigment 24a may be an interference pigment that generates interference light 125a of the same single color as the single color exhibited by the interference pigment 14. Note that the interference pigment 24b may be an interference pigment that generates interference light 126b of the same single color as the single color exhibited by the interference pigment 14.

[0119] The total light transmittance of the printed matter 2 is, for example, 30% to 70%. The total light transmittance here means a value obtained by measuring the total light transmittance using a spectrophotometer (for example, spectrophotometer UV-2100 manufactured by Shimadzu Corporation). When the total light transmittance is 30% or more, when the printed matter 2 is placed in front of the screen, the pattern printing layer 5 becomes difficult to visually recognize due to the light of the image on the screen, and the image is visually recognized more clearly. When the total light transmittance is 70% or less, even if the screen is black, it is possible to suppress the pattern of the pattern printing layer 5 from looking dark.

[0120] Next, with reference to FIGS. 13 and 14, the color combination in the pattern printing layer 5 will be described. FIGS. 13(a) and 13(b) are schematic diagrams showing the color combination of the pattern printing layer 5. FIG. 13(c) is a schematic diagram showing the color combination of the pattern printing layer 105 according to a comparative example. FIG. 14 is a schematic diagram showing a specific example of the color combination of the pattern printing layer 5.

[0121] As shown in FIG. 13(a), in the first color pattern layer 10, an interference pigment of a single color "color A" is included, so that interference light of a single color "color A" is generated. In the second color pattern layer 20, an interference pigment of a single color "color A" and an interference pigment of a single color "color B" are included, so that interference light of a color mixture of "color A" and "color B" is generated. Color B is a color different from color A. Therefore, in the printed matter 2, the pattern is expressed by additive color mixing of the interference light of color A and the interference light of color A and color B.

[0122] Alternatively, as shown in FIG. 13(b), in the second color pattern layer 20, an interference pigment of a single color "color A" is included, so that interference light of a single color "color A" is generated. In the first color pattern layer 10, an interference pigment of a single color "color A" and an interference pigment of a single color "color B" are included, so that interference light of a mixed color of "color A" and "color B" is generated. Color B is a color different from color A. Therefore, in the printed matter 2, a pattern is expressed by additive mixing of the interference light of color A and the interference light of color A and color B.

[0123] In the example shown in FIG. 14(a), "gold" is adopted as color A of the first color pattern layer 10, "gold" is adopted as color A of the second color pattern layer 20, and "red" is adopted as color B. The printed matter 2 may express a wood grain pattern as a pattern by additive mixing of gold and red. Since the first color pattern layer 10 is gold, a light-based wood grain can be expressed. In this case, the interference pigment 14 and the interference pigment 24a shown in FIG. 12 are, for example, gold interference pigments (gold pearl pigments). The interference light 15 and the interference light 125a indicate gold. The interference pigment 24b is, for example, a red interference pigment (red pearl pigment). The interference light 126b indicates red.

[0124] In the example shown in FIG. 14(b), "red" is adopted as color A of the first color pattern layer 10, "red" is adopted as color A of the second color pattern layer 20, and "gold" is adopted as color B. The printed matter 2 may express a wood grain pattern as a pattern by additive mixing of red and gold. Since the first color pattern layer 10 is red, a wood grain with a slightly stronger red tint can be expressed.

[0125] In the example shown in FIG. 14(c), "silver" is adopted as color A of the first color pattern layer 10, and "silver" is adopted as color A and "gold" is adopted as color B of the second color pattern layer 20. The printed matter 2 may express a hairline pattern as a design by additive mixing of silver and gold. By including gold in the second color pattern layer 20, a normal stainless steel hairline can be adjusted to a gold tone. Note that the interference pigments 14 and 24a shown in FIG. 12 are, for example, silver interference pigments (silver pearl pigments). The interference light 15 and the interference light 126a indicate silver.

[0126] In the example shown in FIG. 14(d), "silver" is adopted as color A of the first color pattern layer 10, and "silver" is adopted as color A and "red" is adopted as color B of the second color pattern layer 20. The printed matter 2 may express a hairline pattern as a design by additive mixing of silver and red. By including red in the second color pattern layer 20, a stainless steel hairline can be adjusted to a bronze tone.

[0127] In the example shown in FIG. 14(e), "silver" is adopted as color A and "gold" is adopted as color B of the first color pattern layer 10, and "silver" is adopted as color A of the second color pattern layer 20. The printed matter 2 may express a hairline pattern as a design by additive mixing of gold and silver. By including gold (or a color containing gold) in the first color pattern layer 10, a finish with a more emphasized gold tone can be achieved.

[0128] In the printed matter 2 according to the fourth - first example described above, since one of the pattern layers of the first - color pattern layer 10 and the second - color pattern layer 20 contains interference pigments of multiple colors that generate interference light of different colors A and B, a three - dimensional pattern can be realized even with a small number of printed layers. Further, in this printed matter 2, the pattern layer containing interference pigments that generate a plurality of interference lights may be either the first - color pattern layer 10 or the second - color pattern layer 20, so that the color - matching operation and the alignment operation during printing can be simplified. On the other hand, the other of the first - color pattern layer 10 and the second - color pattern layer 20 contains an interference pigment that generates monochromatic interference light of the same color A as one of the plurality of interference pigments. Here, as a comparative example, as shown in FIG. 13(c), a printed matter 102 is cited in which the first - color pattern layer 10 contains interference pigments of colors X and Y, and the second - color pattern layer 20 contains an interference pigment of color Z. For example, when expressing a pattern as described in FIG. 14 in the configuration of the comparative example, it is necessary to adjust three colors X, Y, and Z, which is time - consuming for the color - matching operation and the alignment operation during printing. On the other hand, for a pattern that can be expressed with a small number of colors as shown in FIG. 14, by limiting the interference pigments of the first - color pattern layer 10 and the second - color pattern layer 20 to a single color A, it is possible to express the pattern by the intensity of the single color A. Also, when it is desired to emphasize the hue of color A, it is easier to adjust the hue by using the two layers of the first - color pattern layer 10 and the second - color pattern layer 20 rather than adjusting with only one color pattern layer. Also, if too many interference pigments are put in one color pattern layer, the strength of the coating film decreases, but by using two color pattern layers 10 and 20, the decrease in strength can be suppressed. From the above, the color - matching operation and the alignment operation during printing can be simplified.

[0129] Also in the fourth example, the configurations according to the first - second to first - fourth examples in the first example may be adopted.

[0130] The printed matter and the display device are not limited to the examples described above, and various other modifications are possible.

[0131] As a printed matter, a sheet in which a pattern layer and a concealment layer are laminated may be adopted. The concealment layer is a layer that conceals the color of the display device when the video is not being displayed and transmits and displays the video when the video is being displayed. The concealment layer is set to have a visible light transmittance within a predetermined range. An opening is formed in the concealment layer. The concealment layer may be printed using an inkjet device, for example, printed with a white ink containing titanium oxide. Specifically, the concealment layer may be, for example, solid white printed on the back surface of the pattern layer. As a printing method, an inkjet device can be exemplified, but it is not limited thereto. As a printing method, in addition to the inkjet printing method, for example, it can be formed by applying various printing methods such as the gravure printing method, the offset printing method, the letterpress printing method, the flexographic printing method, the screen printing method, and the electrostatic printing method. Note that the printing method is not limited to the printing methods exemplified above, and for example, any conventionally known image forming means such as the hand-drawing method, the ink-flowing method, the transfer method, the photographic method, the electrophotographic method, the photosensitive resin method, the vacuum evaporation method, the chemical etching method, the heat-sensitive color development method, and the discharge destruction method can be applied. The pattern layer is formed on the surface of the concealment layer using a printing method and is provided for the purpose of imparting a design property to the printed matter. If the pattern layer has a certain degree of light transmittance, it may be coated over the entire surface. Since the pattern layer does not need to be provided with an opening like the concealment layer, a high-definition design can be provided. Specifically, the pattern layer can be printed using an inkjet device, and as printing ink, for example, a desired pattern may be printed in four colors of cyan, magenta, yellow, and black. Note that, as a printing method of the pattern layer, an inkjet device is exemplified, but it is not limited thereto, and similar to the concealment layer, various printing methods can be applied. Note that the printed matter can adopt a known structure as appropriate as long as it can exhibit the above functions. Although the configuration in which the pattern layer is not provided with an opening has been described, the same function can also be achieved by providing an opening in the pattern layer, so this method can also be adopted.

[0132] Referring to FIG. 15, the concealability and visibility of the printed matter 2 will be described in more detail. Note that the description based on FIG. 15 is merely an exemplary usage mode for explaining the properties of the printed matter 2. Therefore, the present invention need not be limited to such a usage mode. FIGS. 15(a) and 15(b) are views of the light source 3 covered by the printed matter 2 as seen from the front side. FIG. 15(a) shows the state when the power supply of the light source 3 is OFF. FIG. 15(b) shows the state when the power supply of the light source 3 is ON. As the pattern of the printed matter 2, a wood grain pattern is adopted here. As the light source 3, a display device is adopted. Among the printed matter 2, the region covering the light source 3 is referred to as the display region DE. As shown in FIG. 15(a), when the power supply of the light source 3 is OFF, the light source 3 is concealed by the pattern of the printed matter 2. The printed matter 2 does not conceal the light source 3 with a light shielding layer that shields light, but rather conceals the light source 3 with the layer of the pattern itself having light transmissivity. Therefore, the visual information V1 displayed in the display region DE becomes the pattern of the printed matter 2. At this time, the observer cannot visually recognize the display surface (black screen) of the light source 3 and the outline of the light source 3 from outside the printed matter 2. The visual information V1 visible in the display region DE and the visual information V2 visible in the region around the display region DE are the same as the pattern of the printed matter 2. Therefore, the observer cannot visually recognize the presence of the light source 3 from outside the printed matter 2.

[0133] As shown in FIG. 15(b), when the power supply of the light source 3 is ON, the light source 3 emits light and projects an arbitrary image GF onto the display surface. Here, as the image GF, the character "X" shown in a single-color background is adopted. In the display region DE, the light of the image GF passes through the printed matter 2. Thereby, the observer visually recognizes the image GF by visually recognizing the transmitted light in the display region DE. Therefore, the visual information V3 displayed in the display region DE becomes the image GF projected by the light source 3. The content of the visual information V3 may include information not included in the content of the visual information V1. The visual information V3 at this time may be constituted only by the light transmitted through the pattern of the printed matter 2.

[0134] For example, as a comparative example, as a sheet that displays visual information "X" using a light source, there is an example where a part of the light shielding layer is cut out in the shape of "X" to form a light transmission layer (different from the printed matter 2 of the present embodiment). The visual information V3 obtained with such a sheet and a light source such as a lamp is such that the background part is composed of the pattern on the surface of the light shielding layer, and the "X" part is composed of the light of the light source transmitted through the light transmission layer. Alternatively, as a comparative example, there is a sheet in which a light shielding layer in the shape of "X" is formed on a part of the light transmission layer. The visual information V3 obtained with such a sheet is such that the background part is composed of the light of the light source transmitted through the light transmission layer, and the "X" part is composed of the pattern on the surface of the light shielding layer. In the comparative example, the visual information V3 is composed of a combination of the light transmitted through the sheet and the reflected light on the surface of the sheet at the location where the light is shielded. Also, when using a sheet like the comparative example, even when the power supply of the light source is OFF, since the sheet itself is formed in a manner where the shape of "X" can be visually recognized, the content of "X" is also included in the visual information V1. Therefore, the content of the visual information V3 is already included in the visual information V1.

[0135] The visual information V3 in FIG. 15(b) using the printed matter 2 is different from a sheet using a light shielding layer like the comparative example, and the entire visual information is composed of the light transmitted through the printed matter 2. Note that the printed matter 2 shown in FIG. 15 may be entirely composed of a layer that forms a light-transmissive pattern, or at least the entire display area DE may be composed of a layer that forms a light-transmissive pattern. However, also in the printed matter 2, a light shielding layer may be provided in a part of the display area DE, or a light shielding layer may be provided in a part of the area outside the display area DE.

[0136] There is a display device that forms a pattern in anticipation of the content of the image of the light source 3 and forms visual information V3 by combining the pattern and the image when the power of the light source 3 is turned on. In the example shown in FIG. 15, since the purpose is to make it impossible to recognize the presence of the light source 3 from the outside, the visual information V3 in FIG. 15(b) is different from the visual information V3 by such a combination. However, depending on the brightness of the image or the color tone of some areas, it is allowed for the pattern to be faintly reflected in the whole or a part of the visual information V3. Also, for purposes different from the example shown in FIG. 15, there may be a case where visual information V3 that combines and cooperates the pattern and the image of the printed matter 2 is adopted. When a touch panel is adopted as the light source 3, the user operates the touch panel through the printed matter 2. Therefore, the printed matter 2 may be set to a thickness, material, and hardness that do not impede the touch panel operation.

[0137] Specific examples of the closet door and the closet according to the embodiment of the present invention will be described below with reference to the drawings. Note that the present invention is not limited to these examples, and is defined by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims. In the following description, the same reference numerals are given to the same elements in the description of the drawings, and duplicate descriptions are omitted.

[0138] FIG. 16 is a front view showing the closet 300 according to the present embodiment. FIG. 17 is a cross-sectional view taken along line II-II shown in FIG. 16. As shown in FIGS. 16 and 17, the closet 300 includes an opening 305 formed in the wall 303 and a plurality of closet doors 301 that cover the opening 305. In the following description, the terms "upper", "lower", "right", "left", "front", and "back" may be used based on the front view of the closet 300 (the state shown in FIG. 16).

[0139] As shown in Fig. 17, the opening 305 is formed by being recessed from the surface 303a of the wall 303 toward the back side by a predetermined distance. The closet 300 has a storage section 310 inside the opening 305. The storage section 310 is an internal space for storing various items. The storage section 310 has a bottom surface 310a spaced apart from the surface 303a of the wall 303 toward the back side, an upper surface 310b, a floor 304, and an internal space surrounded by a plurality of closet doors 301.

[0140] The closet 300 has a storage structure 316 capable of storing the information home appliance 320. The information home appliance 320 is a home appliance of an information communication system such as a control device for HEMS, a display device, a wireless LAN router, etc. The storage structure 316 is composed of a shelf portion or the like that projects from the bottom surface 310a toward the front side within the storage section 310. The storage structure 316 installs the information home appliance 320 on the shelf portion. Also, the storage section 310 can store the self-propelled cleaner 330. The self-propelled cleaner 330 is arranged on the floor 304 within the storage section 310.

[0141] As shown in Fig. 16, the closet door 301 is a plate-like member arranged to be substantially flush with the surface 303a of the wall 303. The number of closet doors 301 is not particularly limited, but in this embodiment, four closet doors 301 are provided. The closet door 301 is provided so as to extend in the vertical direction between the floor 304 and the ceiling 306 at the position of the surface 303a of the wall 303.

[0142] The closet 300 has a waste heat section 307 for waste heat when the information home appliance 320 is stored at least above any one of the plurality of closet doors 301. In the example shown in Fig. 16, the waste heat section 307 is provided on all four closet doors 301. The waste heat section 307 is configured as a through section that penetrates the closet door 301 on the upper surface 310b of the storage section 310 by notching the upper part of the closet door 301. Alternatively, the waste heat section 307 is configured by providing a gallery. The heat generated from the information home appliance 320 and radiated into the interior of the storage section 310 moves upward and is wasted to the outside through the waste heat section 307 (see Fig. 17).

[0143] The cabinet 300 has a passage portion 308 through which the self-propelled cleaner 330 can pass at least at the lower part of any one of the plurality of cabinet doors 301. In the example shown in FIG. 16, the passage portion 308 is provided in the leftmost cabinet door 301. The passage portion 308 is configured as a through portion that penetrates the cabinet door 301 at the position on the floor 304 side of the storage portion 310 by separating the lower portion of the cabinet door 301 upward from the floor 304. Inside the storage portion 310, the self-propelled cleaner 330 waits in a charged state at the charging portion 331 (see FIG. 17). When performing cleaning, the self-propelled cleaner 330 moves outside the cabinet 300 through the passage portion 308 to perform cleaning. When the cleaning is finished, the self-propelled cleaner 330 moves into the storage portion 310 of the cabinet 300 through the passage portion 308 and is charged at the charging portion 331.

[0144] As shown in FIG. 16, among the plurality of cabinet doors 301, at least one cabinet door 201 has a video display portion 206. In the present embodiment, the second cabinet door 301 from the left is the cabinet door 201 according to the present embodiment. The cabinet door 201 has a video display portion 206 at a predetermined height position from the floor 304.

[0145] The dimensions are not particularly limited, but the vertical dimension H1 between the floor 304 and the ceiling 306 may be set to 2250 to 2800 mm. The vertical dimension H2 of the cabinet door 301 may be set to 2035 to 2300 mm (for example, 2200 mm). The vertical height dimension H3 of the video display portion 206 may be set to 900 to 1500 mm (for example, 1300 mm). The width dimension W of the cabinet door 301 may be set to 140 to 600 mm (for example, 400 mm). The vertical dimension L of the passage portion 308 may be set to a dimension through which the self-propelled cleaner 330 can pass (for example, 100 mm). Note that a 12.1 to 24-inch (for example, 15-inch) video display portion 206 may be adopted.

[0146] Next, with reference to FIGS. 18 to 20, the closet door 201 according to this embodiment will be described in detail. FIG. 18 is a perspective view showing the closet door 201 according to this embodiment. FIG. 19 is a perspective view showing the usage state. FIG. 19 is a cross-sectional view of the closet door 201.

[0147] As shown in FIG. 18, the closet door 201 includes a decorative sheet 202, a support frame 203, a base member 204, and a video display unit 206. In the following description, the thickness direction of the closet door 201 will be referred to as "D1", and the horizontal width direction of the closet door 201 will be referred to as "D2" for explanation. The closet door 201 has a rectangular shape when viewed from the front. In this embodiment, the closet door 201 has a rectangular shape with a longitudinal direction in the vertical direction. However, the shape of the closet door 201 is not particularly limited.

[0148] The decorative sheet 202 is a sheet-like member for covering the opening 305 (see FIG. 17). The decorative sheet 202 also covers the video display unit 206. The decorative sheet 202 has a larger area than the video display unit 206. The decorative sheet 202 covers the video display unit 206 in a partial region E. A pattern is shown on the surface 202a of the decorative sheet 202. The pattern is not particularly limited, and any pattern that can give a design to the closet door 201 may be used. For example, patterns such as a wood grain pattern, a stone grain pattern, and an abstract pattern may be adopted. The pattern of the decorative sheet 202 of the closet door 201 having the video display unit 206 is the same as the pattern of the other closet door 302.

[0149] In the region E of the surface 202a of the decorative sheet 202, the video is displayed when the video display unit 206 displays the video (see FIG. 19(a)), and the pattern of the decorative sheet 202 is displayed when the video display unit 206 does not display the video (see FIG. 19(b)). As the decorative sheet 202 that realizes such a function, a known decorative sheet 202 may be adopted.

[0150] For example, as the decorative sheet 202, a sheet in which a pattern layer and a concealment layer are laminated may be adopted. The concealment layer is a layer that conceals the color of the video display unit 206 when the video is not being displayed and transmits and displays the video when the video is being displayed. The concealment layer is set to have a visible light transmittance within a predetermined range. An opening is formed in the concealment layer. The concealment layer may be printed using an inkjet device, for example, printed with a white ink containing titanium oxide. Specifically, the concealment layer may be, for example, solid white printed on the back surface of the pattern layer. As the printing method, an inkjet device can be exemplified, but it is not limited thereto. As the printing method, in addition to the inkjet printing method, for example, it can be formed by applying various printing methods such as the gravure printing method, the offset printing method, the letterpress printing method, the flexographic printing method, the screen printing method, and the electrostatic printing method. Note that the printing method is not limited to the printing methods exemplified above. For example, any conventionally known image forming means such as the hand-drawing method, the ink-flowing method, the transfer method, the photographic method, the electrophotographic method, the photosensitive resin method, the vacuum evaporation method, the chemical etching method, the heat-sensitive coloring method, and the discharge destruction method can be applied. The pattern layer is formed on the surface of the concealment layer using a printing method and is provided for the purpose of imparting design characteristics to the decorative sheet 202. If the pattern layer has a certain degree of light transmittance, it may be applied over the entire surface. Since the pattern layer does not need to be provided with openings like the concealment layer, a high-definition design can be provided. Specifically, the pattern layer can be printed using an inkjet device, and as the printing ink, for example, a desired pattern may be printed in four colors of cyan, magenta, yellow, and black. Note that, as the printing method of the pattern layer, an inkjet device has been exemplified, but it is not limited thereto. Similar to the concealment layer, various printing methods can be applied. Note that the decorative sheet 202 can adopt a conventionally known structure as appropriate as long as it can exhibit the above functions.

[0151] The support frame 203 is a member that supports the edge of the cosmetic sheet 202. In the present embodiment, the support frame 203 has a rectangular frame shape. The support frame 203 has the same shape as the cosmetic sheet 202 when viewed in the thickness direction D1. The support frame 203 includes a wall portion 203a that supports the right edge of the cosmetic sheet 202, a wall portion 203b that supports the left edge, a wall portion 203c that supports the upper edge, and a wall portion 203d that supports the lower edge. The material of the support frame 203 is not particularly limited, and metals, resins, etc. may be adopted.

[0152] The base member 204 is a plate-like member that constitutes the back surface of the closet door 201. Also, the base member 204 supports the video display unit 206 on the surface side. The base member 204 has a rectangular shape. The base member 204 has the same shape as the cosmetic sheet 202 when viewed in the thickness direction D1. A support frame 203 is provided at the edge of the base member 204.

[0153] The video display unit 206 is a device that displays video. As the video display panel used for the video display unit 206, a flat display device is preferably used for efficient space mounting. As the video display unit 206, an LED display in which a large number of LED elements are arranged in an array may be adopted. Alternatively, as the video display unit 206, a liquid crystal display, a plasma display, an organic EL display, etc. may be adopted. Also, a touch panel display device (such as an organic EL touch panel) may be adopted as the video display unit 206. The video displayed by the video display unit 206 can be appropriately selected according to the purpose. The video may adopt information such as characters and patterns, visual information such as photos, and video such as an operation screen. The video display unit 206 is covered by the cosmetic sheet 202 while being supported by the base member 204.

[0154] Next, with reference to Fig. 20(a), the cross-sectional structure of the closet door 201 will be described. The rear end of the support frame 203 is fixed in contact with the surface of the base member 204. The method of fixing the support frame 203 to the base member 204 is not particularly limited, and it may be fixed using an adhesive, double-sided tape, or the like. The back surface of the video display unit 206 is fixed in contact with the surface of the base member 204. The method of fixing the video display unit 206 to the base member 204 is not particularly limited, and it is fixed by methods such as an adhesive, screwing, or double-sided tape.

[0155] In the form shown in Fig. 20(a), the decorative sheet 202 is supported by the support frame 203 in a state where tension is applied. The four edges of the decorative sheet 202 are fixed to the front ends 209 of the wall portions 203a, 3b, 3c, 3d of the support frame 203. During manufacturing, for example, one edge in the longitudinal direction of the decorative sheet 202 is fixed to the wall portion 203c. While maintaining the state where tension is applied to the decorative sheet 202, the other edges of the decorative sheet 202 are fixed to the ends 209 of the wall portions 203a, 3b and the wall portion 203d. As a result, after fixing, the decorative sheet 202 maintains a state where tension acts, sagging is suppressed, and high smoothness is maintained. In a state of being supported by the support frame 203 with such high smoothness, the display surface 206a of the video display unit 206 contacts the back surface 202b of the decorative sheet 202. Here, the thickness in the thickness direction D1 of the support frame 203 is set to be approximately the same as the thickness of the video display unit 206. Therefore, the decorative sheet 202 can contact the display surface 206a in a state where the formation of a gap between the decorative sheet 202 and the display surface 206a at the position of the video display unit 206 is suppressed, and deformation due to being pressed too hard by the display surface 206a is suppressed. The decorative sheet 202 and the display surface 206a are not directly fixed.

[0156] Note that the cosmetic sheet 202 only contacts the video display unit 206 in the area on the inner peripheral side of the fixing part with the support frame 203 at the edge. That is, the cosmetic sheet 202 does not contact other members in the area between the edge and the video display unit 206. For example, when the cosmetic sheet 202 contacts a member other than the video display unit 206, it is necessary to control the dimensional accuracy of the member so that the cosmetic sheet 202 is not deformed by being pressed too hard by the member. In this embodiment, such control of the dimensional accuracy of the member is not required.

[0157] In order to enhance the smoothness of the cosmetic sheet 202, the configuration of Fig. 20(b) may be adopted. In the form shown in Fig. 20(b), the closet door 201 further includes a transparent substrate 207. The substrate 207 supports the cosmetic sheet 202 when the cosmetic sheet 202 is attached thereto. As the substrate 207, a panel with high smoothness may be adopted. The material of the substrate 207 is not particularly limited. For example, as a synthetic resin plate, a transparent resin plate such as an acrylic resin plate, a polycarbonate resin plate, or a vinyl chloride resin plate can be used. Alternatively, glass may be adopted as the material of the substrate 207. The back surface 202b of the cosmetic sheet 202 is attached to the substrate 207 in a state of contacting the front surface 207a of the substrate 207. The display surface 206a of the video display unit 206 contacts the back surface 207b of the substrate 207 without a gap. Note that the edge of the substrate 207 is fixed to the end 209 of the support frame 203.

[0158] Note that the substrate 207 is in contact only with the video display unit 206 in the area on the inner peripheral side of the fixing portion with the support frame 203 at the edge. That is, the substrate 207 is not in contact with other members in the area between the edge and the video display unit 206. For example, when a configuration is adopted in which a frame or the like is provided for the substrate 207 to support the video display unit 206, the substrate 207 and the decorative sheet 202 may be distorted by the load. On the other hand, if the thickness of the substrate 207 is increased to ensure strength without distortion, the gap between the display surface 206a of the video display unit 206 and the decorative sheet 202 will increase, and the image will be easily blurred. In the form of Fig. 20(b), since no load acts on the substrate 207, the smoothness of the decorative sheet 202 can be ensured.

[0159] As shown in Figs. 20(a) and (b), the video display unit 206 is fixed to the base member 204 without interposing other members between them. The video display unit 206 is in contact with the decorative sheet 202 (or the substrate 207) without interposing other members between them. Therefore, the closet door 201 can be configured to be thin.

[0160] The video display unit 206 may display information about the stored items stored in the storage unit 310. For example, the video display unit 206 may display the contents of the stored items. For example, when the information appliance 320 is stored in the storage unit 310, the video display unit 206 may display the contents and type of the information appliance 320. Also, when the self-propelled cleaner 330 is stored in the storage unit 310, the video display unit 206 may display that the self-propelled cleaner 330 is stored and its type. When other stored items are stored in the storage unit 310, the video display unit 206 may display the contents of the other stored items. In addition, the video display unit 206 may display any information.

[0161] The video display unit 206 may display the video without operating the remote control. When the video is not displayed, since the video display unit 206 is hidden by the pattern of the decorative sheet 202, when the user enters the room, the user may not notice the existence of the video display unit 206 or may not be able to recognize the location. Therefore, the video display unit 206 may automatically display a message or the like at the timing when the user enters the room. Alternatively, the video display unit 206 may automatically display a message or the like at the timing when the user approaches. Also, after the video is displayed, the video display unit 206 may display the video without the user operating the remote control via a touch panel or the like. Note that the user may operate the video display unit 206 by operating the remote control.

[0162] Next, the operations and effects of the closet door 201 and the closet 300 according to the present embodiment will be described.

[0163] In recent years, there have been changes in household appliances used in homes. The household penetration rate of robot vacuum cleaners has continued to increase, reaching 8.3% in 2022. Home Wi-Fi has also become more prevalent due to the increase in telecommuting during the COVID-19 pandemic, and some data shows that more than 90% of households have a Wi-Fi environment at home. In conventional houses, there was no space to store such devices in the first place, and the placement of such devices sometimes became a problem.

[0164] On the other hand, in the closet door 201 according to the present embodiment, in the region E of the surface 202a of the decorative sheet 202, the video is displayed when the video display unit 206 displays the video. Therefore, at the timing when it is necessary to display the video, the video can be displayed on the surface 202a of the decorative sheet 202. On the other hand, when the video display unit 206 does not display the video, the pattern of the decorative sheet 202 is displayed. Therefore, when the video is not displayed, since the video display unit 206 is hidden by the pattern, it becomes difficult to recognize the existence of the video display unit 206. From the above, when the video is not displayed, the recognition of the existence of the video display unit 206 is suppressed, and the video can be displayed at the necessary timing.

[0165] The closet door 201 may further include a transparent substrate 207 that supports the decorative sheet 202 by having the decorative sheet 202 attached thereto (see Fig. 20(b)). In this case, the decorative sheet 202 can cover the video display unit 206 in a highly smooth state by being supported by the substrate 207.

[0166] In the closet door 201, the video display unit 206 may display an image without operating a remote control. In this case, the video display unit 206 can display an image even when it is difficult to recognize the presence of the video display unit 206 through the decorative sheet 202.

[0167] The closet 300 according to this embodiment is a closet 300 in which at least one of a plurality of closet doors 301 is the above-described closet door 201 having a video display unit 206, and the pattern of the decorative sheet 202 of the closet door 201 having the video display unit 206 is the pattern of the other closet door 302.

[0168] In this closet 300, the pattern of the decorative sheet 202 of the closet door 201 having the video display unit 206 is the pattern of the other closet door 302. Therefore, the closet door 201 having the video display unit 206 can exist without a sense of incongruity as a series of closet doors 301.

[0169] In the closet 300, the video display unit 206 may display the contents of the stored items. In this case, the stored items can be easily confirmed from the outside of the closet 300.

[0170] The closet 300 may have a storage structure 316 capable of storing the information appliance 320. In this case, it becomes possible to efficiently store the information appliance 320, which is a new information and communication-based appliance, in the closet 300. Further, since the information of the information appliance 320 can also be projected onto the video display unit 206 attached to the closet door 201, there is no need to open the closet door 201 for confirmation.

[0171] The cabinet 300 may have a waste heat section 307 for waste heat when the information appliance 320 is stored at least above one of the plurality of cabinet doors 301. In this case, when the information appliance 320 is stored, it is possible to suppress heat from accumulating inside the cabinet 300.

[0172] The cabinet 300 may have a passage section 308 through which the self-propelled cleaner 330 can pass at least below one of the plurality of cabinet doors 301. In this case, after the cleaning is completed, the self-propelled cleaner 330 can automatically enter the cabinet 300 through the passage section 308. Therefore, the self-propelled cleaner 330 can be automatically stored in the cabinet 300.

[0173] The present invention is not limited to the above-described embodiments.

[0174] For example, the position and quantity of the cabinet door 201 having the video display section 206 among the plurality of cabinet doors 301 are not limited, and all of them may be cabinet doors 201 having the video display section 206.

[0175] Also, a door structure having the same gist as the above-described cabinet door 301 may be adopted for the entrance storage door. FIG. 21 is a front view showing the entrance storage door 401 according to the embodiment. Note that the same reference numerals are given to the configurations having the same gist as the above-described cabinet door 301 and cabinet 300, and unless otherwise specified, they have the same gist of configuration and effect. Hereinafter, mainly the differences between the entrance storage door 401 and the entrance storage 400 and the cabinet door 301 and the cabinet 300 will be described. FIG. 22 is a cross-sectional view taken along line XXII-XXII shown in FIG. 21.

[0176] As shown in FIGS. 21 and 22, the entrance storage door 401 is an entrance storage door 401 provided at the opening 305 of the entrance storage 400, and includes a decorative sheet 202 for covering the opening 305 and a video display unit 206 covered by a partial area of the decorative sheet 202 and for displaying video. In the surface area of the decorative sheet 202, video is displayed when the video display unit 206 displays video, and the pattern of the decorative sheet 202 is displayed when the video display unit 206 does not display video.

[0177] Further, the entrance storage 400 is an entrance storage 400 in which at least one of the plurality of entrance storage doors 501 is the entrance storage door 401 having the video display unit 206, and the pattern of the decorative sheet 202 of the entrance storage door 401 having the video display unit 206 is the pattern of the other entrance storage door 502.

[0178] According to such an entrance storage door 401 and entrance storage 400, the same functions and effects as those of the aforementioned closet door 201 and closet 300 can be obtained.

[0179] The dimensions of the entrance storage door 401 and the entrance storage 400 are not particularly limited, but the vertical dimension H1 between the tatami 412 and the ceiling 306 may be set to 2250 to 2800 mm. The vertical dimension H2 of the entrance storage door 401 may be set to 2000 to 2400 mm (for example, 2200 mm). The vertical height dimension H3 of the video display unit 206 may be set to 900 to 1300 mm (for example, 1300 mm). The width dimension W of the entrance storage door 401 may be set to 300 to 600 mm (for example, 400 mm). The video display unit 206 may be one with 12 to 32 inches (for example, 24 inches).

[0180] A camera 410 is provided on the entrance storage door 401. In the figure, the camera 410 is attached at the position of the waste heat part 307. At this location, the camera 410 may be directly attached to the entrance storage door 401, or may be attached to the upper surface 310b on the body side. Also, the camera 410 may be provided around the video display unit 206 or in front of the video display unit 206. At this time, the camera 410 may be provided so as to be concealed by a decorative sheet. The camera 410 may photograph a person present at the entrance. The camera 410 may be equipped with a face recognition system. In this case, the camera 410 can identify a person at the entrance.

[0181] The entrance storage door 401 may further be provided with a human presence sensor 411. The human presence sensor 411 is a sensor that detects the arrival of a person at the entrance. Thereby, the video display unit 206 may also operate only when a person arrives as detected by the human presence sensor 411.

[0182] The video display unit 206 may display any one of a weather forecast and news, personal network information, an image of a person photographed by the camera 410 attached to the entrance storage, and information inside the entrance storage 400. Thereby, the user can grasp this information at the entrance. By touching the video display unit 206, the user can operate the video.

[0183] The video display unit 206 may display a weather forecast or news obtained via a network. Also, when the video display unit 206 identifies a person at the entrance by the camera 410, it can obtain and display information such as the personal schedule of the target person via the network.

[0184] Here, in a conventional entrance hall, a mirror is installed for things like checking one's appearance, and before going out, one checks one's outfit. However, since only the front state is reflected in front of the mirror, the back state cannot be checked. In contrast, in the entrance hall storage 400, the video display unit 206 may display the information captured by the camera 410, that is, the image of the person in front of the camera 410. In this case, a person can check their outfit at the entrance hall without using things like a dressing mirror. Also, by a person rotating their body once in front of the camera 410 and watching the recorded video, it is possible to check the entire outfit without using a three-way mirror. In this way, in the entrance hall storage door 401, in order to check one's outfit at the entrance hall, it is possible to check not only the front but also the back. Also, a person can check their outfit while checking information such as the weather forecast and news and then go out.

[0185] The video display unit 206 may display the information inside the entrance hall storage 400. Thereby, the user can check the information before opening the entrance hall storage door 401 and the entrance hall storage 400. When information appliances are stored in the entrance hall storage 400, the video display unit 206 may display the content and type of the information appliances.

[0186] A control unit may be built into the entrance hall storage door 401. Such a control unit processes the video sent from the camera 410 and switches the video to be displayed on the video display unit 206 at the necessary timing. Also, it can acquire network information and display it together.

[0187] As described above, the entrance hall storage door 401 is provided with the video display unit 206. Also, the entrance hall storage 400 is provided with the camera 410. This camera 410 can recognize a person. With such a configuration, the information displayed on the entrance hall storage door 401 can display a person in front of the camera 410 together with network information such as the weather forecast, news, and personal schedules. Furthermore, when the video is not being displayed, the recognition of the presence of the video display unit 206 can be suppressed, and it can be displayed at the necessary timing.

[0188] A decorative sheet 202 is pasted on the entrance storage door 401, and the video display unit 206 is hidden by the pattern of the decorative sheet 202. When the user enters the room, they may not notice the presence of the video display unit 206 or may not be able to recognize its location. The camera 410 is attached to the upper part of the entrance storage door 401, and a person can also be displayed in front of the camera 410. Also, the camera 410 can acquire information such as weather forecasts, news, and personal schedules, which are displayed together with network information.

[0189] When the video is not being displayed, a frame may be provided around the video display unit 206 to suppress recognition of its presence. Further, a display for displaying information such as weather forecasts and news may be installed at the upper part of the entrance storage door 401. Also, a board for recording personal schedules and the like may be installed inside the entrance storage 400. This information may be acquired via a network.
