DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0027] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. In the following description, the same or corresponding elements are designated by the same reference numerals, and duplicated description will be omitted.

[0028] [First embodiment] FIG. 1 is a perspective view showing a decorative panel according to the first embodiment. FIG. 2 is a front view showing a decorative panel according to the first embodiment. FIG. 3 is a plan view showing a decorative panel according to the first embodiment. FIG. 4 is a bottom view showing a decorative panel according to the first embodiment. FIG. 5 is an end view taken along the line VV shown in FIG. 2. As shown in FIGS. 1 to 5, the decorative panel 1 according to this embodiment is a panel that is attached to a surface to be decorated (not shown) such as a wall or a ceiling in order to decorate the surface. The decorative panel 1 includes a frame member 2, a back panel 3, and a decorative material 4. In the following description, the front and rear directions of the decorative panel 1 refer to the front and rear directions of the decorative panel 1 when the decorative panel 1 is attached to the surface to be decorated. In other words, when the decorative panel 1 is attached to the surface to be decorated, the direction facing the surface to be decorated is referred to as the rear, and the direction facing the opposite side to the surface to be decorated is referred to as the front.

[0029] The frame member 2 is a member that functions as a frame for the decorative panel 1. The frame member 2 includes, for example, an outer frame portion 21 formed in a rectangular frame shape, and an auxiliary frame portion 22 disposed inside the outer frame portion 21 and connected to the outer frame portion 21. The auxiliary frame portion 22 may be formed in a cross shape and connected to a pair of vertical frame portions and a pair of horizontal frame portions of the outer frame portion 21, or may be formed in a straight line and connected to a pair of vertical frame portions of the outer frame portion 21, or may be formed in a straight line and connected to a pair of horizontal frame portions of the outer frame portion 21.

[0030] The rear panel 3 is a member fixed to the frame member 2 and forms the rear surface of the decorative panel 1. The rear panel 3 has, for example, approximately the same outer shape as the outer shape of the frame member 2, and is fixed to the frame member 2 while being disposed in front of the frame member 2.

[0031] The decorative material 4 is a member that is decorated to decorate the surface to be decorated. The decorative material 4 is held by the frame member 2 so as to cover the front of the back panel 3. In other words, the decorative material 4 has a decorative portion 41 located in front of the back panel 3 and a holding portion 42 held by the frame member 2. The decorative portion 41 is located in the center of the decorative material 4, and the holding portion 42 is located on the periphery of the decorative material 4.

[0032] The holding portion 42 is formed so as to cover the frame member 2 from the outside, and is attached to the frame member 2. The holding portion 42 can be attached to the frame member 2 by, for example, adhesion, pinning, or the like.

[0033] FIG. 6 is an enlarged plan view of the area surrounded by the VIa-VIa portion and the VIb-VIb portion shown in FIG. 3. FIG. 7 is an enlarged plan view of a part of the decorative portion. As shown in FIGS. 1 to 3 and 5 to 7, the decorative portion 41 is a portion that imparts decorativeness to the decorative panel 1. In the decorative portion 41, a plurality of see-through portions 43 having see-through properties are regularly arranged. The portion of the decorative portion 41 other than the see-through portions 43 is a portion that does not have see-through properties. The see-through portions 43 having see-through properties mean that they have light transmittance and that the other side of the see-through portions 43 can be seen through the see-through portions 43. Therefore, the shadow of the decorative portion 41 appears on the rear panel 3 due to the light that has passed through the plurality of see-through portions 43, and in the decorative portion 41, it is possible to see the rear panel 3 and the shadow of the decorative portion 41 that appears on the rear panel 3 through the plurality of see-through portions 43. Among the front and back surfaces of the rear panel 3, a surface located on the decorative portion 41 side where the shadow of the decorative portion 41 appears due to light transmitted through the multiple see-through portions 43 is referred to as a shadow appearing surface 31. The multiple see-through portions 43 may be provided not only on the decorative portion 41 but also on the entire decorative material 4. In this embodiment, the multiple see-through portions 43 are provided on the entire decorative material 4.

[0034] The see-through portion 43 may have any structure as long as it has see-through properties. For example, the see-through portion 43 may be a hole penetrating the decorative material 4, or may be a transparent portion to the extent that it is see-through. The degree of see-through property refers to the extent to which the shadow of the decorative portion 41 appearing on the shadow appearing surface 31 can be seen through the see-through portion 43. When the see-through portion 43 is a hole penetrating the decorative material 4, the visible light transmittance of the see-through portion 43 is 100%. On the other hand, when the see-through portion 43 is not a hole penetrating the decorative material 4, the see-through portion 43 has see-through properties, so that the visible light transmittance of the see-through portion 43 is preferably 30% or more, more preferably 40% or more, and even more preferably 50% or more.

[0035] The decorative material 4 may be, for example, a woven fabric, a knitted fabric, a mesh material formed into a mesh shape such as expanded metal, a perforated board, a perforated material with holes such as punched metal, etc. The woven fabric may be, for example, a multiaxial fabric such as a triaxial fabric. When the decorative material 4 is formed into a mesh shape, the mesh openings become the see-through portions 43 (holes penetrating the decorative material 4). When the decorative material 4 is formed into a perforated shape, the holes formed in the decorative material 4 become the see-through portions 43 (holes penetrating the decorative material 4).

[0036] Furthermore, the decorative material 4 may be, for example, the above-mentioned mesh material or perforated material overlaid with a transparent film. When the decorative material 4 is a mesh material overlaid with a transparent film, the portions of the transparent film overlaid with the mesh holes become the see-through portions 43 (portions that are transparent enough to allow for see-through). When the decorative material 4 is a perforated material overlaid with a transparent film, the portions of the transparent film overlaid with the holes in the perforated material become the see-through portions 43 (portions that are transparent enough to allow for see-through).

[0037] The decorative material 4 may be made of, for example, resin such as polyester, metal such as aluminum or stainless steel, natural material such as wood, stone or cotton, or a combination of these. The decorative material 4 may be decorated in addition to the material color. Examples of the method of decoration include known printing methods such as gravure, inkjet, and screen, and known coating methods such as brush painting, roller brush painting, spatula painting, air spray painting, airless spray painting, dip painting, electrostatic painting, electrodeposition painting, powder coating, curtain flow coater painting, and roller coater painting.

[0038] The decorative portion 41 has a three-dimensional shape. That is, the decorative portion 41 is formed three-dimensionally in front of the rear panel 3. As a result, a space is formed between the multiple see-through portions 43 and the shadow appearing surface 31.

[0039] Here, if a space is formed between the regularly-arranged multiple see-through parts 43 and the shadow appearing surface 31, when the decorative part 41 is viewed from the front of the decorative panel 1, moire is likely to appear due to interference between the multiple see-through parts 43 and the shadows of the decorative part 41 that appear on the shadow appearing surface 31. For this reason, by adding a moire design to the design of the decorative part 41, a complex design appears in the decorative part 41. Note that in order for moire to appear, it is not necessary for all the see-through parts 43 of the decorative part 41 to have a space between them and the shadow appearing surface 31, and it is sufficient that at least some of the see-through parts 43 of the decorative part 41 have a space between them and the shadow appearing surface 31.

[0040] From the viewpoint of facilitating the appearance of moire, it is preferable that the decorative portion 41 has an area where the distance between the multiple see-through portions 43 and the shadow appearing surface 31 is 50 cm or less. In this case, the distance between the multiple see-through portions 43 and the shadow appearing surface 31 in that area is more preferably 30 cm or less, and even more preferably 10 cm or less. The area where the distance between the multiple see-through portions 43 and the shadow appearing surface 31 is 50 cm or less, 30 cm or less, or 10 cm or less is, for example, preferably 50% or more of the entire decorative portion 41, more preferably 60% or more, and even more preferably 70% or more.

[0041] Moreover, from the viewpoint of facilitating the appearance of moire, it is preferable that the decorative portion 41 has an area where the distance between the multiple see-through portions 43 and the shadow appearing surface 31 is 1 cm or more. In this case, the distance between the multiple see-through portions 43 and the shadow appearing surface 31 in that area is more preferably 2 cm or more, and even more preferably 3 cm or more. The area where the distance between the multiple see-through portions 43 and the shadow appearing surface 31 is 1 cm or more, 2 cm or more, or 3 cm or more is, for example, preferably 50% or more of the entire decorative portion 41, more preferably 60% or more, and even more preferably 70% or more.

[0042] Moreover, from the viewpoint of making the shadow of the decorative portion 41 appearing on the shadow appearing surface 31 easily visible from the see-through portion 43, the diameter D (see FIG. 7) of the inscribed circle C of the see-through portion 43 is preferably 1 mm or more, more preferably 2 mm or more, and even more preferably 3 mm or more. On the other hand, from the viewpoint of making moire easily appear, the diameter D of the inscribed circle C of the see-through portion 43 is preferably 10 mm or less, more preferably 9 mm or less, and even more preferably 8 mm or less. From these viewpoints, the diameter D of the inscribed circle C of the see-through portion 43 is preferably 1 mm or more and 10 mm or less, more preferably 2 mm or more and 9 mm or less, and even more preferably 3 mm or more and 8 mm or less.

[0043] In order to prevent moire from appearing, the number of see-through portions 43 per unit area in the decorative portion 41 is set to 1 per cm 2 More than 2 pieces / cm is preferable. 2 More preferably, 3 pieces / cm or more. 2 On the other hand, from the viewpoint of facilitating the production of the decorative material 4, the number of the see-through parts 43 per unit area in the decorative part 41 is preferably 15 pieces / cm. 2 Preferably, 10 pieces / cm or less. 2 More preferably, 8 pieces / cm or less. 2 From these viewpoints, the number of the see-through portions 43 per unit area in the decorative portion 41 is preferably 1 / cm or less. 2More than 15 pieces / cm 2 Preferably less than 2 pieces / cm 2 More than 10 pieces / cm 2 More preferably, 3 / cm or less. 2 More than 8 pieces / cm 2 It is more preferable that the number of see-through portions 43 per unit area is equal to or less than the above. The number of see-through portions 43 per unit area can be calculated, for example, from the number of see-through portions 43 in any 10 cm square area of ​​the decorative portion 41.

[0044] In order to prevent moire from appearing easily, the lightness of the shadow appearing surface 31 of the rear panel 3 is preferably equal to or greater than 30, more preferably equal to or greater than 40, and even more preferably equal to or greater than 50. Here, lightness refers to the L* value in the L*a*b* color system, and more specifically, refers to the L* value obtained by measurement in a color mode (L*a*b*) using a color difference meter CR-400 manufactured by Konica Minolta.

[0045] The decorative part 41 has a mountain part 44 that rises in a direction away from the shadow appearance surface 31. The shape of the mountain part 44 is not particularly limited, but may be, for example, a polygonal pyramid such as a triangular pyramid or a quadrangular pyramid, a cone, or a hemisphere. In these cases, from the viewpoint of improving the shape retention of the mountain part 44, it is preferable that the mountain part 44 has a shape having a folding line part 45 formed by bending the decorative part 41 like a polygonal pyramid. The folding line part 45 includes a ridge line part 45a in which the decorative part 41 is bent in a mountain fold, and a valley line part 45b in which the decorative part 41 is bent in a valley fold. The folding line part 45 may extend linearly, may be curved, or may be bent. The folding line part 45 may be branched into multiple parts. The mountain part 44 may have one folding line part 45 or multiple folding line parts 45. The mountain part 44 may have one apex or multiple apexes. In addition, the peaks 44 may have a flat top, a dotted top, a linear top, or a flat top. In this embodiment, the decorative part 41 has two quadrangular pyramid-shaped peaks 44, one valley line 45b extending linearly between the two peaks 44, and six ridge lines 45a extending linearly toward the apexes of each peak 44.

[0046] In this way, in the decorative panel 1 according to this embodiment, a plurality of see-through parts 43 having transparency are regularly arranged in the decorative part 41 forming the front surface of the decorative panel 1, and since there is a space between the plurality of see-through parts 43 and the shadow appearing surface 31, it is possible to make a moire pattern appear due to interference between the plurality of see-through parts 43 and the shadows of the decorative part 41 that appear on the shadow appearing surface 31. This allows a moire pattern to be added to the design of the decorative part 41, thereby improving the design of the decorative panel 1.

[0047] In addition, this decorative panel 1 has an area where the distance between the multiple see-through parts 43 and the shadow appearing surface 31 is 50 cm or less, 30 cm or less, or 10 cm or less, so that the shadows of the decorative parts 41 appearing on the shadow appearing surface 31 can be easily viewed from the see-through parts 43. This makes it easier to make moire appear.

[0048] Furthermore, this decorative panel 1 has an area where the distance between the multiple see-through parts 43 and the shadow appearing surface 31 is 1 cm or more, 2 cm or more, or 3 cm or more, thereby making it possible to increase the interference between the multiple see-through parts 43 and the shadows of the decorative parts 41 that appear on the shadow appearing surface 31. This makes it easier to make moire appear.

[0049] In addition, in this decorative panel 1, since the see-through portion 43 is a hole penetrating the decorative portion 41, the shadow of the decorative portion 41 appearing on the shadow appearing surface 31 can be easily seen from the see-through portion 43, making it easier to make moire appear.

[0050] Furthermore, in this decorative panel 1, if the see-through portion 43 is not a hole penetrating the decorative portion 41, the visible light transmittance of the see-through portion 43 is 30% or more, 40% or more, or 50% or more, so that the shadow of the decorative portion 41 appearing on the shadow appearing surface 31 can be easily viewed from the see-through portion 43. This makes it easier to make moire appear.

[0051] Furthermore, in this decorative panel 1, since the decorative portion 41 is formed in a mesh shape, the plurality of see-through portions 43 can be easily formed.

[0052] Furthermore, in this decorative panel 1, since the decorative portion 41 is made of a woven fabric, the plurality of see-through portions 43 can be easily formed.

[0053] In addition, in this decorative panel 1, the diameter D of the inscribed circle C of the see-through portion 43 is 1 mm or more and 10 mm or less, 2 mm or more and 9 mm or less, or 3 mm or more and 8 mm or less, so that the shadow of the decorative portion 41 appearing on the shadow appearing surface 31 can be easily seen from the see-through portion 43 and moire can be easily caused to appear.

[0054] In addition, in this decorative panel 1, the number of the see-through portions 43 per unit area is 1 / cm 2 More than 15 pieces / cm 2 Below, 2 pieces / cm 2 More than 10 pieces / cm 2 Less than or equal to 3 pieces / cm 2 More than 8 pieces / cm 2By keeping the thickness within this range, it becomes easier to make moire patterns appear and the decorative material 4 can be easily produced.

[0055] In addition, in this decorative panel 1, the decorative portion 41 has a three-dimensional shape, so that the shape of the moire that appears can be made complex. This makes it possible to further improve the design of the decorative panel 1.

[0056] Furthermore, in this decorative panel 1, the decorative portion 41 has the ridges 44 that rise in a direction away from the shadow appearing surface 31, so that moire fringes in the shape of contour lines corresponding to the ridges 44 can be made to appear.

[0057] Furthermore, in the decorative panel 1, the decorative portion 41 has a folding line portion 45 formed by bending, so that the shape retention can be improved. This allows the three-dimensional shape of the decorative portion 41 to be easily retained.

[0058] Furthermore, this decorative panel 1 can produce moire patterns using only the decorative panel 1 by providing the rear panel 3 that forms the shadow producing surface 31. This increases the freedom of choice when selecting a location for installing the decorative panel 1.

[0059] In addition, in this decorative panel 1, since the brightness of the shadow appearing surface 31 of the rear panel 3 is 30 or more, 40 or more, or 50 or more, the shadow appearing on the shadow appearing surface 31 is easily visible from the see-through portion 43, making it easier to make moire appear.

[0060] [Second embodiment] The second embodiment is basically the same as the first embodiment, and differs from the first embodiment only in that the shape of the decorative portion is different and a spacer is further provided. Therefore, in the following description, only the differences from the first embodiment will be described, and the description of the similarities to the first embodiment will be omitted.

That is, the decorative part 41A has a plurality of transparent parts 43 arranged regularly, similar to the decorative part 41 of the first embodiment. The decorative part 41A is formed planarly in front of the rear panel 3, and a space is formed between the decorative part 41A and the rear panel 3 by the spacer 5A.

[0066] In this manner, in the decorative panel 1A according to this embodiment, the decorative portion 41A has a planar shape, so that the decorative material 4A can be easily produced.

[0067] Furthermore, in this decorative panel 1A, by providing the spacer 5A disposed between the decorative portion 41A and the shadow appearing surface 31, spaces can be easily formed between the multiple see-through portions 43A and the shadow appearing surface 31.

[0068] Although an embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and may be modified or applied to other things without departing from the gist of the claims.

[0069] For example, in the first embodiment, the three-dimensional shape of the decorative part 41 is maintained by the rigidity of the decorative part 41, but the three-dimensional shape of the decorative part 41 may also be maintained by attaching a shape-retaining member such as a wire to the decorative part 41.

[0070] In the first embodiment, the decorative part 41 has a plurality of peaks 44, and each peak 44 has a plurality of fold lines. However, for example, as in the decorative panel 1B shown in Figs. 10 and 11, the decorative part 41 may have one peak 44B without fold lines. Fig. 10 is a front view showing another example of the decorative panel. Fig. 11 is an end view taken along the line XI-XI shown in Fig. 10. In this case, the three-dimensional shape of the decorative part 41B may be maintained by using a decorative material 4B having rigidity, or by attaching a shape-retaining member such as a wire to the decorative part 41B, or by attaching the decorative panel 1B to the ceiling and allowing the decorative part 41B to hang down under its own weight, thereby maintaining the three-dimensional shape of the decorative part 41B.

[0071] In the first and second embodiments, the back panel is provided, but the back panel may not be provided, as in the case of the decorative panel 1C shown in FIG. 12 and the decorative panel 1D shown in FIG. 13. FIGS. 12 and 13 are end views showing other examples of decorative panels. When the decorative panel does not have a back panel, the surface to be decorated on which the decorative panel is attached becomes a shadow appearance surface on which the shadow of the decorative part appears due to the light transmitted through the multiple see-through parts. In other words, since the decorative panel is attached to the surface to be decorated to decorate the surface to be decorated, the shadow appearance surface on which the shadow of the decorative part appears due to the light transmitted through the multiple see-through parts does not need to be a configuration of the decorative panel itself, but at least it is sufficient that the shadow of the decorative part appears due to the light transmitted through the multiple see-through parts when the decorative panel is attached to the surface to be decorated. Even if the surface to be decorated on which the decorative panel is attached is a shadow appearance surface, the position of this shadow appearance surface is uniquely determined by the configuration of the decorative panel, since it is the mounting surface of the decorative panel relative to the surface to be decorated.

[0072] 12 is similar to the decorative panel 1 of the first embodiment, except that it does not include a rear panel and an auxiliary frame portion of the frame member. In this decorative panel 1C, the surface S to be decorated on which the decorative panel 1C is attached becomes a shadow appearing surface on which the shadow of the decorative portion 41 appears due to light transmitted through the multiple see-through portions 43 when the decorative panel 1C is attached to the surface S to be decorated. For this reason, it is possible to make a moire pattern appear due to interference between the multiple see-through portions 43 and the shadow of the decorative portion 41 that appears on the surface S to be decorated, which is the shadow appearing surface.

[0073] The decorative panel 1D shown in Fig. 13 is similar to the decorative panel 1A of the second embodiment, except that it does not include a back panel, an auxiliary frame portion of the frame member, and a spacer. In this decorative panel 1D, the surface S to be decorated on which the decorative panel 1D is attached becomes a shadow appearance surface on which the shadow of the decorative portion 41A appears due to light transmitted through the multiple see-through portions 43 when the decorative panel 1D is attached to the surface S to be decorated. In the decorative panel 1D, a space is formed between the multiple see-through portions 43 and the surface S to be decorated, which is the shadow appearance surface, by the frame member 2. Therefore, it is possible to make a moire appear due to interference between the multiple see-through portions 43 and the shadow of the decorative portion 41A that appears on the surface S to be decorated, which is the shadow appearance surface. EXAMPLES

[0074] The present invention will be described in more detail with reference to the following examples, but the present invention is not limited to these examples.

[0075] Decorative panels of Examples 1 to 7 and Comparative Examples 1 to 8 were produced.

[0076] The decorative panel of Example 1 was prepared by placing a planar mesh-shaped decorative material made of fibers at a distance of 5 cm from the rear panel on a rear panel with an L* value (brightness) of 50 measured using the color display mode (L*a*b*) of a Konica Minolta CR-400 color difference meter. In other words, the decorative panel of Example 1 had a plurality of see-through parts regularly arranged on the decorative part forming the front surface of the decorative panel, and the distance between the plurality of see-through parts and the shadow appearance surface of the rear panel was 50 cm.

[0077] The decorative panel of Example 2 was prepared by placing a three-dimensional mesh-like decorative material made of fibers at a space of 5 cm from the rear panel on a rear panel with an L* value (brightness) of 50 measured using the color display mode (L*a*b*) of a color difference meter CR-400 manufactured by Konica Minolta, Inc. In other words, the decorative panel of Example 2 was the same as the decorative panel of Example 1, except that a three-dimensional decorative material was used.

[0078] The decorative panel of Example 3 was prepared by placing a mesh-like planar decorative material made of fibers at a space of 5 cm from the rear panel on a rear panel with an L* value (brightness) of 80 as measured using a color display mode (L*a*b*) of a Konica Minolta CR-400 color difference meter. In other words, the decorative panel of Example 3 was the same as the decorative panel of Example 1, except that a rear panel with a brightness of 80 was used.

[0079] The decorative panel of Example 4 was prepared by placing a mesh-like planar decorative material made of fibers at a space of 5 cm from the rear panel on a rear panel with an L* value (brightness) of 30 as measured using the color display mode (L*a*b*) of a Konica Minolta CR-400 color difference meter. In other words, the decorative panel of Example 4 was the same as the decorative panel of Example 1, except that a rear panel with a brightness of 30 was used.

[0080] The decorative panel of Example 5 was prepared by placing a mesh-like planar decorative material made of fibers at a distance of 50 cm from the rear panel on a rear panel having an L* value (brightness) of 50 measured using a color display mode (L*a*b*) of a Konica Minolta CR-400 color difference meter. In other words, the decorative panel of Example 5 was the same as the decorative panel of Example 1, except that the distance between the multiple see-through parts of the decorative part forming the front surface of the decorative panel and the shadow appearing surface of the rear panel was 50 cm.

[0081] The decorative panel of Example 6 was prepared by placing a mesh-like planar decorative material made of fibers at a space of 5 cm from the rear panel on a rear panel with an L* value (brightness) of 20 as measured using a color display mode (L*a*b*) of a Konica Minolta CR-400 color difference meter. In other words, the decorative panel of Example 6 was the same as the decorative panel of Example 1, except that a rear panel with a brightness of 20 was used.

[0082] The decorative panel of Example 7 was prepared by placing a planar mesh-shaped decorative material made of fibers 55 cm away from the rear panel on a rear panel with an L* value (brightness) of 50 measured using the color display mode (L*a*b*) of a Konica Minolta CR-400 color difference meter. In other words, the decorative panel of Example 7 was the same as the decorative panel of Example 1, except that the distance between the multiple see-through parts of the decorative part forming the front surface of the decorative panel and the shadow appearing surface of the rear panel was 55 cm.

[0083] The decorative panel of Comparative Example 1 was prepared by placing a planar mesh-shaped decorative material made of fibers on a rear panel with an L* value (brightness) of 50 measured using the color display mode (L*a*b*) of a Konica Minolta CR-400 color difference meter, without leaving any space between the rear panel and the decorative material. In other words, the decorative panel of Comparative Example 1 was the same as the decorative panel of Example 1, except that there was no space between the rear panel and the decorative material.

[0084] The decorative panel of Comparative Example 2 was prepared by placing a decorative material having a planar shape of a transparent film 5 cm away from the rear panel on a rear panel having an L* value (brightness) of 50 measured using the color display mode (L*a*b*) of a Konica Minolta CR-400 color difference meter. In other words, the decorative panel of Comparative Example 2 was the same as the decorative panel of Example 1, except that a decorative material that was entirely transparent and had multiple transparent parts not regularly arranged was used.

[0085] The decorative panel of Comparative Example 3 was prepared by placing a planar decorative material made of resin with no holes on the entire surface, with a space of 5 cm from the rear panel, on a rear panel with an L* value (brightness) of 50 measured using the color display mode (L*a*b*) of a color difference meter CR-400 manufactured by Konica Minolta, Inc. In other words, the decorative panel of Comparative Example 3 was the same as the decorative panel of Example 1, except that a decorative material without a see-through portion was used.

[0086] The decorative panels of Examples 1 to 7 and Comparative Examples 1 to 8 were fixed to the wall of a room with lighting, and the designs were visually confirmed from a position 2 m away from the wall. When the moire design was clearly visible, the moire evaluation was rated A, when the moire design was unclear but visible, the moire evaluation was rated B, and when the moire design was not visible, the moire evaluation was rated C. The evaluation results are shown in Table 1.

[0087] [Table 1]

[0088] As shown in Table 1, Comparative Examples 1 to 3 all received a moire evaluation of C, while Examples 1 to 7 all received a moire evaluation of A or B. From these results, it was found that by regularly arranging multiple see-through parts in the decorative part and providing a space between the multiple see-through parts and the rear panel (the surface where the shadow appears), it is possible to make a moire appear, thereby making it possible to add a moire design to the design of the decorative part, thereby improving the design of the decorative panel.

[0089] Moreover, Example 6, which had a brightness of 20, received a moire evaluation of B, but Examples 1 to 5, which had a brightness of 30 or more, all received a moire evaluation of A. This result shows that a rear panel with a brightness of 30 or more makes it easier for moire to appear.

[0090] Moreover, Example 7, in which the space between the decorative material and the rear panel exceeded 50 cm, received a moire evaluation of B, while Examples 1 to 6, in which the space between the decorative material and the rear panel was 50 cm or less, all received a moire evaluation of A. From this result, it was found that moire is more likely to appear when the space between the multiple see-through parts and the shadow appearing surface is 50 cm or less. [Explanation of symbols]
