panels include perforated panels having holes penetrating in the thickness direction and a fiber layer covering the holes from the back side. Conventional screens, such as those described in Patent Document 1, do not transmit sound well, making it difficult to place a sound source on the back side. In contrast, Patent Document 2 describes providing holes in a panel and further filling these holes with a porous material. However, there is room for further improvement in this configuration. The screen device of (21) described above was made based on these circumstances and aims to provide a screen device that can easily and efficiently enhance the sense of presence of images and sounds by transmitting sound from the back side while suppressing a decrease in visibility. According to the screen device of (21), the sense of presence of images and sounds can be easily and efficiently enhanced by transmitting sound from the back side while suppressing a decrease in visibility. 【0031】(22) In the screen device of (21), the plurality of panels may include one or more perforated panels arranged according to the positions of one or more sound-emitting devices arranged on the back side of the screen, and one or more normal panels that do not have the holes and the fiber layer. 【0032】 (23) In the screen apparatus of (21) or (22) above, the fiber layer may have a flat portion that is positioned on the back of the perforated panel and a convex portion that protrudes from the flat portion and fills the holes. 【0033】 In this disclosure, "front" means the side from which the image light is projected, and "back" means the opposite side. "Long member" means a member whose longitudinal length is greater than its width. The lower limit of the ratio of longitudinal length to width may be, for example, 15, 20, 25, or 30. The upper limit of the ratio may be, for example, 60 or 50. "Long" includes string-like, strip-like (flat), plate-like, thread-like, etc. "Strip-like" means having flexibility, for example, being able to be wound up in the thickness direction. "Plate-like" means having rigidity. 【0034】 "Horizontal direction" means the horizontal direction in the state in which it is formed on the suspended screen. "Up" means the top in the state in which it is formed on the suspended screen, and "down" means the bottom in the state in which it is formed on the suspended screen. "Rectangular" includes perfectly rectangular and substantially rectangular shapes. "Substantially rectangular" includes shapes in which the corners are chamfered or shapes in which irregularities are formed on any side, to the extent that the effects of this disclosure are achieved. "Same optical properties" does not mean exactly the same properties, but rather the same properties to the extent that the effects of this disclosure are achieved. 【0035】The embodiments of this disclosure will be described in detail below, with reference to the drawings as appropriate. It should be noted that, regarding the numerical values ​​described herein, only one of the upper or lower limits may be adopted, or the upper and lower limits may be combined in any way. This specification lists all possible numerical ranges as preferred ranges. Furthermore, the figures are schematic and may not correspond to actual dimensions, proportions, etc. In this disclosure, the designations "First," "Second," and "Third" are for distinguishing the components to which they are attached, and do not limit the number, order, priority, etc. 【0036】[First Embodiment] <Suspended Screen Device> The suspended screen device 60 shown in Figure 1 (hereinafter also simply referred to as "screen device 60") comprises a plurality of panels 61 that are configured as a screen while suspended from another member 101. The plurality of panels 61 include one or more uppermost panels 62 arranged at the top of the screen, and one or more lower panels 63 arranged below the uppermost panels 62. The number of lower panels 63 arranged below one uppermost panel 62 may be one or more. Figure 1 shows a configuration in which a plurality of lower panels 63 are arranged below one uppermost panel 62. As shown in Figures 2 and 3, each of the plurality of panels 61 has a connecting portion 64 that can be connected to other panels 61 adjacent in the vertical direction. That is, each of the plurality of panels 61 can be said to be connected to other panels 61 adjacent in the vertical direction via a connecting portion 64. Furthermore, as shown in Figure 1, the uppermost panel 62 has a connecting portion 65 that can be connected to other members 101 so that it can be suspended from other members 101. In this disclosure, when it is said that each of the multiple panels "has a connecting portion that can be connected to other panels adjacent in the vertical direction," it means that if there are other panels adjacent in the vertical direction, it has a connecting portion that can be connected to those other panels. For example, the uppermost panel may only have a connecting portion that can be connected to other panels adjacent below it, and one or more panels arranged at the bottom of the screen (hereinafter also referred to as the "bottom panel") may only have a connecting portion that can be connected to other panels adjacent above it. Also, when a panel "has a connecting portion that can be connected to other panels adjacent in the vertical direction," the multiple panels adjacent in the vertical direction may be directly connected to each other by the connecting portions, or the connecting portions may be indirectly connected to each other via another member. 【0037】The screen device 60 may be formed as a suspended screen at the place of use such as an event or an exhibition, and may be disassembled from the suspended screen after use at the place of use. Further, the screen device 60 can also be used as a permanent screen in a movie theater or the like. The screen device 60 is formed as a suspended screen by connecting the connection part 65 provided on the uppermost panel 62 to another member 101 installed at the place of use. Typically, the screen device 60 is formed as a suspended screen by arranging a plurality of uppermost panels 62 (four are shown in FIG. 1) horizontally and suspending them from another member 101. The screen device 60 can easily form into a suspended screen and disassemble from the suspended screen by the attaching and detaching operation between the uppermost panel 62 and the other member 101. Further, the screen device 60 can be transported and stored in units of a plurality of panels 61. Therefore, the screen device 60 is excellent in handling property. 【0038】 The screen device 60 does not require a frame, a stand, or the like for supporting the plurality of panels 61. Therefore, the screen device 60 is lightweight and is also excellent in handling property in this regard. Further, since it does not require the frame, the stand, or the like, it is easy to transport. 【0039】 The screen device 60 can change the number and arrangement of the panels 61 according to the use scene. The screen device 60 can form, for example, a flat or curved screen of any size with an area of 3 m ２ or more (hereinafter, the flat screen and the curved screen are also collectively referred to as "flat screen etc."). In particular, the screen device 60 may be formed as a large flat screen etc. at an event, an exhibition, or the like. When the screen device 60 is formed as a large flat screen etc., the superiority of the handling property is remarkably exhibited. The lower limit of the area of the large flat screen etc. is not particularly limited, but it may be 40 m ２ or it may be 50 m ２ or it may be 100 m ２It may be. Also, as the upper limit of the area such as a large flat screen, etc., although not particularly limited, 550 m ２ is also acceptable, 500 m ２ is also acceptable, 450 m ２ is also acceptable. 【0040】 As described above, the screen device 60 is configured as a screen while being suspended from another member 101. Examples of the other member 101 include a horizontal bar included in a baton device such as a stage device or a suspended object device installed at the place of use. In this case, if the horizontal bar is formed in a straight line, the screen device 60 can be formed as a flat screen. On the other hand, the screen device 60 may be formed into a screen other than a flat screen such as a curved screen. For example, if the horizontal bar is formed in a curved shape, the screen device 60 can be easily formed as a curved screen. 【0041】 (Panel) The uppermost panel 62 has a panel body 66 used as a part of the screen, a connection portion 65 connected to another member 101, and a connection portion 64 connected to another panel 61 (that is, the lower panel 63) adjacent below. The lower panel 63 has a panel body 66 used as a part of the screen and a connection portion 64 connected to other panels 61 adjacent in the vertical direction. In both the uppermost panel 62 and the lower panel 63, video light is projected onto the panel body 66. The shapes of the panel bodies 66 in the plurality of panels 61 may be the same or different for each of the plurality of panels 61. The screen device 60 can easily improve the handling property by having the same shape of the panel bodies 66 in the plurality of panels 61. The panel body 66 may be rectangular in a front view. In particular, the screen device 60 may include two or more panel bodies 66 that are rectangular and have the same shape in a front view, or all the panel bodies 66 included in the screen device 60 may be rectangular and have the same shape in a front view. Hereinafter, the case where all the panel bodies 66 are rectangular and have the same shape in a front view will be described. 【0042】As shown in Figure 4, the panel body 66 has a first screen sheet 21, a first light-shielding film 22, and a base material 23. The panel body 66 may have the first screen sheet 21, the first light-shielding film 22, and the base material 23 in this order from the front side to the back side. The panel body 66 may also have a back-side light-shielding film 68 and a reinforcing sheet 69 on the back side of the base material 32 in this order. The first screen sheet 21, the first light-shielding film 22, the base material 23, the back-side light-shielding film 68, and the reinforcing sheet 69 may be fixed with an adhesive. In the panel body 66, the first screen sheet 21, the first light-shielding film 22, the base material 23, the back-side light-shielding film 68, and the reinforcing sheet 69 may be indirectly laminated with another member in between, but direct lamination is preferred. Alternatively, instead of the above configuration, the panel body 66 may have a pair of first light-shielding films 22 and a pair of first screen sheets 21 sandwiching the base material 23. For example, the panel body 66 may have the first screen sheet 21, the first light-shielding film 22, the base material 23, the first light-shielding film 22, and the first screen sheet 21 in this order from the front to the back. The first screen sheet 21, the first light-shielding film 22, and the base material 23 may be indirectly laminated with another member in between, but direct lamination is preferred. The first screen sheet 21, the first light-shielding film 22, and the base material 23 may be fixed with an adhesive. 【0043】 The panel body 66 can have its reflectivity improved by having a first screen sheet 21, a first light-shielding film 22, and a base material 23. As a result, the clarity, brightness, etc., of the projected image can be improved. In addition, the panel body 66 can suppress the transmission of light from the back side by having a light-shielding film (back side light-shielding film 68 or first light-shielding film 22) on the back side of the base material 23. Furthermore, the panel body 66 can prevent unintended deformation such as warping by having a reinforcing sheet 69. Note that warping can also be prevented if the panel body 66 has a pair of first light-shielding films 22 and a pair of first screen sheets 21 sandwiching the base material 23. 【0044】[First Screen Sheet] The first screen sheet 21 is placed on the outermost surface of the panel body 66, for example. The first screen sheet 21 is made of a resin mainly composed of polyethylene, polypropylene, polyester, polyvinyl chloride, etc. The front surface of the first screen sheet 21 is white so as to reflect image light. The first screen sheet 21 may be colored white by a white coating. The thickness of the first screen sheet 21 is not particularly limited, but can be several micrometers to several hundred micrometers. 【0045】 [First Light-Blocking Film] The first light-blocking film 22 is positioned on the back of the first screen sheet 21 to improve the reflectivity of the image light. The first light-blocking film 22 also blocks the incidence of external light from the back of the first screen sheet 21. The first light-blocking film 22 may be formed of, for example, a metal foil or a metal vapor-deposited film. From the viewpoint of reflectivity, aluminum, silver, etc., can be used as the metal. Among these, aluminum is preferred because it is low cost and lightweight, and aluminum foil is preferred from the viewpoint of improving the clarity and brightness of the projected image, improving the ability to prevent warping of the panel body 66, and further enhancing flame retardancy. The thickness of the first light-blocking film 22 is not particularly limited, but can be from a few nanometers to several hundred nanometers. The lower limit of the light-blocking rate of the first light-blocking film 22 may be 99.40%, 99.80%, or 99.99%. The upper limit of the light-blocking rate is 100%. 【0046】 Preferably, at least the front side of the first light-shielding film 22 has specular reflection properties. According to this embodiment, light leaking from the first screen sheet 21 to the back side can be reflected, improving the visibility (quality) of the image projected onto the first screen sheet 21. Furthermore, if the panel body 66 has the pair of first light-shielding films 22, it is also preferable that the first light-shielding film 22 positioned on the back side has specular reflection properties on the back side. According to this embodiment, ambient light incident from the back of the panel 2 can be reflected, making it easier to further improve the visibility of the image projected onto the first screen sheet 21. 【0047】[Base Material] The base material 23 is flat. The base material 23 is, for example, made of metal, resin, or wood. From the perspective of weight reduction, the base material 23 is preferably made of resin, and may be, for example, made of foamed resin. When the base material 23 is made of resin, particularly foamed resin, for example, the weight of the panel body 66 alone can be made about 500 g or less. As a result, the handling property of the panel 61 can be improved, and the total weight of a plurality of panels 61 can be kept low, facilitating the enlargement of the screen size. The thickness of the base material 23 is not particularly limited, but from the perspective of sufficiently maintaining the strength of the panel 2, it can be several cm to several tens of cm. 【0048】 [Backside Light-Shielding Film] The backside light-shielding film 68 is composed of, for example, a black sheet. By being black, the backside light-shielding film 68 is likely to prevent the transmission of light incident from the backside. Examples of the main component of the backside light-shielding film 68 include polyvinyl chloride (PVC). By the main component of the backside light-shielding film 68 being PVC, in addition to light-shielding property, flame retardancy can be improved. The lower limit of the PVC content in the backside light-shielding film 68 may be 60% by mass, 70% by mass, 80% by mass, or 90% by mass. 【0049】 [Reinforcement Sheet] The reinforcement sheet 69 is disposed on the rearmost surface of the panel body 66. The reinforcement sheet 69 does not necessarily need to be disposed on the entire back surface of the panel body 66, and may be partially disposed on the back surface of the panel body 66 according to the strength required for the panel body 66. The reinforcement sheet 69 only needs to have a strength capable of suppressing warping and the like of the panel body 66, and its material is not particularly limited. The reinforcement sheet 69 may have, for example, metal as the main component. 【0050】 The planar area of the panel body 66 can be set from the perspective of, for example, achieving both the transportability of the panel 61 and the efficiency of forming and disassembling a suspended screen. The lower limit of the planar area is, from the perspective of the transportability of the panel 61, for example, 0.2 m ２ and may be 0.3 m ２ and may be 0.4 m ２ and may be 0.45 m ２This is also acceptable. On the other hand, the upper limit of the planar area is 1.0 m, from the viewpoint of efficiency in forming and disassembling the suspended screen. ２ It may also be 0.8m ２ It may also be 0.7m ２ That's fine. 【0051】 (Panel Groups) As shown in Figure 1, the screen device 60 has panel groups 67a to 67d, which consist of one uppermost panel 62 and one or more lower panels 63 connected below the uppermost panel 62. The screen device 60 is suspended from other members 101 for each panel group 67a to 67d. According to this embodiment, the screen device 60 can be transported and stored in units of panel groups 67a to 67d, improving handling. 【0052】 In each panel group 67a to 67d, there is no particular limit to the number of lower panels 63 connected below the uppermost panel 62. However, in the screen device 60, the vertical size of the screen is determined by the number of panels 61 included in each panel group 67a to 67d. Therefore, the lower limit for the number of lower panels 63 connected below the uppermost panel 62 may be two, four, or six. 【0053】 In the screen device 60, there is no particular upper limit on the number of panels 61 arranged in the vertical direction. For example, as shown in Figure 5, the lowest panel 63a may be held in a state where it is floating above the floor surface 201 when formed as a screen. 【0054】On the other hand, as shown in Figure 6, at least a portion of the lower panels 63, including the bottom panel 63a, may be placed on the floor 201. That is, the lower panels 63 may include surplus panels 63b that are folded at the bottom of the screen and placed on the floor 201. In Figure 6, multiple surplus panels 63b are placed on the floor 201. Of the multiple surplus panels 63b, the panel located at the bottom (i.e., the panel directly in contact with the floor 201) is the bottom panel 63a. Even if each panel group 67a to 67d of the screen device 60 includes more panels 61 than the number actually used as a screen (i.e., panels 61 that are not actually used as a screen), some of the panels 61 can be folded and placed on the floor 201 as surplus panels 63b. Therefore, the screen device 60 can easily realize screens of different sizes according to the location and usage scenario of events, exhibitions, etc., and is highly versatile. Furthermore, by arranging some of the panels 61 as surplus panels 63b on the floor surface 201, the screen device 60 can use the surplus panels 63b as weights, making it easier to maintain the entire screen in the desired shape. 【0055】 (Connection part) As described above, the uppermost panel 62 has a connection part 65 that can be connected to other members 101. The specific configuration of the connection part 65 is not particularly limited as long as it has sufficient strength to support the weight of the panel groups 67a to 67d suspended from the other members 101. The specific configuration of the connection part 65 can be set according to the shape of the other members 101, but for example it may have a winding part that can be wrapped around a horizontal bar. 【0056】 (Connecting section) As described above, multiple panels 61 adjacent to each other in the vertical direction are connected via connecting sections 64. This configuration facilitates handling of the panel groups 67a to 67d at each stage, such as transportation and storage. 【0057】The connecting portion 64 preferably connects a plurality of panels 61 adjacent to each other in the vertical direction so that they can be folded. This embodiment makes it easier to handle each panel group 67a to 67d. The plurality of panels 61 included in each panel group 67a to 67d preferably fold in an accordion shape. This embodiment makes it possible to reduce the storage space for each panel group 67a to 67d and facilitates the formation and disassembly of the screen. 【0058】 As shown in Figure 2, the connecting portion 64 is provided on the upper and lower surfaces (upper and lower sides) of the panel body 66. Furthermore, the connecting portion 64 is provided on both sides in the width direction of the panel body 66 (i.e., one connecting portion 64 is provided on each side in the width direction of the upper surface of the panel body 66, and one connecting portion 64 is provided on each side in the width direction of the lower surface). Connecting portions 64 provided on multiple vertically adjacent panels 61 are connected directly or indirectly via another member. As shown in Figures 2 and 3, the connecting portion 64 has, for example, an axis member 64a. The central axis of the axis member 64a is positioned horizontally. Furthermore, axis members 64a provided on vertically adjacent panels 61 are rotatably connected to the connecting member 64b. That is, each of the multiple panels 61 has an axis member 64a that can be connected to the connecting member 64b. The connecting member 64b has a connected portion 64c to which the axis member 64a is connected. The connecting portion 64c is, for example, a hole into which the shaft member 64a is inserted. Panels 61 adjacent to each other in the vertical direction are connected in a foldable manner as a result of their respective shaft members 64a being rotatably connected to the connecting member 64b. The shaft member 64a may be provided so as not to be detachable from the connecting member 64b, or it may be detachable. If the shaft member 64a and the connecting member 64b are not detachable, the stability of the screen suspension is improved. On the other hand, if the shaft member 64a and the connecting member 64b are detachable, the vertical length of the panel groups 67a to 67d can be changed depending on the place of use, etc. As an example of a configuration in which the shaft member 64a and the connecting member 64 are detachable, the shaft member 64a may be formed as a threaded member. The position and number of connecting portions 64 can be adjusted as appropriate according to the size and weight of the panels 61, etc. 【0059】In this way, in the screen device 60, multiple panels 61 adjacent to each other in the vertical direction are pre-connected. On the other hand, in the screen device 60, it is preferable that each of the multiple panels 61 is not directly connected to other panels 61 adjacent to each other in the horizontal direction. More specifically, it is preferable that multiple panels 61 adjacent to each other in the horizontal direction are not connected to each other, except in the case that they are connected via a blocking member 42 described later. According to this embodiment, interference from the horizontal direction is eliminated, and each panel group 67a to 67d can be maintained in a state where it is suspended from other members 101 by gravity. As a result, it is possible to make it easier to maintain the screen in the desired shape, to make the screen easier to form and disassemble, and to improve the durability of the device. 【0060】 [Method for forming a suspended screen] Next, a method for forming a suspended screen using the screen device 60 shown in Figure 1 (hereinafter also simply referred to as "the said forming method") will be described. In this forming method, as shown in Figure 7, the connecting part 65 provided on the uppermost panel 62 is connected to another member 101 (connecting step), and the other member 101 is raised (raising step). 【0061】 (Connection Step) In the connection step, for example, multiple uppermost panels 62 are arranged horizontally, and the connection parts 65 provided on the multiple uppermost panels 62 are connected to the other member 101. Preferably, the connection step is performed with the other member 101 lowered to a position where a worker on the floor 201 can perform the connection work. 【0062】 (Raising step) In the raising step, the other members 101 are raised while the multiple uppermost panels 62 are connected to the other members 101. As the other members 101 are raised, the panels 61 included in each panel group 67a to 67d, which are folded in a bellows-like manner, are unfolded, and a suspended screen is formed. 【0063】 According to this forming method, a suspended screen can be easily formed. In particular, since this forming method does not require specialized knowledge to form a suspended screen, anyone can easily form one. 【0064】 [Method for disassembling a suspended screen] Next, a method for disassembling a suspended screen formed using the screen device 60 shown in Figure 1 (hereinafter also simply referred to as "the disassembly method") will be described. In this disassembly method, as shown in Figure 8, the other members 101 are lowered (lowering step), and the connecting part 65 provided on the uppermost panel 62 is removed from the other members 101 (removal step). 【0065】 (Lowering step) In the lowering step, for example, with multiple uppermost panels 62 connected to other members 101, the other members 101 are lowered. At this time, it is also preferable to fold the panels 61 included in the multiple panel groups 67a to 67d while lowering the other members 101. 【0066】 (Removal Step) In the removal step, the connecting parts 65 provided on the multiple uppermost panels 62 are removed from the other members 101. Preferably, the removal step is performed with the other members 101 lowered to a position where an operator on the floor 201 can perform the removal work. 【0067】 According to this disassembly method, no specialized knowledge is required to disassemble the hanging screen, making it easy for anyone to do so. 【0068】 [Second Embodiment] <Suspended Screen Device> The suspended screen device 70 shown in Figure 9 (hereinafter also simply referred to as "screen device 70") comprises a plurality of panels 61 suspended from other members 101. The screen device 70 also further comprises a closing member 42 that closes the gap between the front surfaces of adjacent plurality of panels 61. The screen device 70 can have the same configuration as the screen device 60 in Figure 1, except that it comprises a closing member 42 and the panel body 66 has a magnet 41a. 【0069】In a suspended screen formed using the screen device 60 shown in Figure 1, gaps may be formed between multiple adjacent panels 61 in the vertical or horizontal direction. The larger these gaps become, the more noticeable they are, and the more likely they are to cause discomfort to the viewer. In this regard, the screen device 70 includes a closing member 42 that closes the gaps between the front surfaces of multiple adjacent panels 61 (i.e., between the surfaces on which the image light is projected on multiple adjacent panel bodies 66), so that the viewer can see (view) the desired image without discomfort. 【0070】 (Closing Member) As shown in Figures 10 and 11, the closing member 42 is a sheet member that can be attached to multiple panels 61. According to this embodiment, the gap between the front surfaces of the panels 61 can be easily and reliably closed. 【0071】 The closing member 42 may have a rectangular shape in front view, for example, having a longer side corresponding to the length of one side of the panel 61 and a shorter side wider than the gap between adjacent panels 61. According to this embodiment, the gaps in the entire screen can be easily closed by closing each gap between adjacent panels 61 with the closing member 42. On the other hand, the size and shape of the closing member 42 are not limited to the above configuration, and for example, it may be designed to close a gap extending vertically or horizontally across two or more panels 61 with a single closing member 42. Furthermore, the closing member 42 may be designed to cover not only the gaps between adjacent panels 61 but also part or all of the front surface of the panel 61. 【0072】 The thickness of the occlusion member 42 can be, for example, several micrometers to several hundred micrometers. In the screen device 70, multiple occlusion members 42 may be stacked in multiple layers in some areas. Even in such cases, if the thickness of the occlusion member 42 is within the above range, it is difficult for the viewer to see the boundary between the occlusion member 42 and the panel 61, even when viewing the screen from an oblique angle. Therefore, it is possible to prevent the viewer from feeling uncomfortable due to the overlapping of multiple occlusion members 42. 【0073】As shown in Figure 11, the closure member 42 has a second screen sheet 51 and a second light-shielding film 52. The closure member 42 also has a magnetic sheet 53. The optical properties of the second screen sheet 51 may be the same as those of the first screen sheet 21. The optical properties of the second light-shielding film 52 may also be the same as those of the first light-shielding film 22. The closure member 42 may have the same optical properties as either the second screen sheet 51 and the first screen sheet 21, or the same optical properties as either the second light-shielding film 52 or the first light-shielding film 22. On the other hand, it is preferable that the closure member 42 has a second screen sheet 51 having the same optical properties as the first screen sheet 21, and a second light-shielding film 52 having the same optical properties as the first light-shielding film 22. The blocking member 42 can uniformly improve the reflectivity of the entire screen by ensuring that either the optical properties of the second screen sheet 51 and the first screen sheet 21, or the optical properties of the second light-shielding film 52 and the first light-shielding film 22 are the same. As a result, the clarity and brightness of the projected image can be uniformly improved across the entire screen. Furthermore, the above-mentioned effect is particularly pronounced when the optical properties of the second screen sheet 51 and the first screen sheet 21 are the same, and the optical properties of the second light-shielding film 52 and the optical properties of the first light-shielding film 22 are the same. In this disclosure, "optical properties" may include, for example, reflectivity, transmittance, and absorptiveness. In this disclosure, for example, by controlling one or more of reflectivity, transmittance, and absorptiveness, the clarity and brightness of the projected image can be uniformly improved across the entire screen. 【0074】 The closure member 42 may have a second screen sheet 51, a second light-shielding film 52, and a magnetic sheet 53 arranged in this order from the front to the back. The second screen sheet 51, the second light-shielding film 52, and the magnetic sheet 53 may be indirectly laminated with another member in between, but direct lamination is preferred. The second screen sheet 51, the second light-shielding film 52, and the magnetic sheet 53 may be fixed with an adhesive. 【0075】[Second Screen Sheet] The second screen sheet 51 may be made of a resin mainly composed of polyethylene, polypropylene, polyester, polyvinyl chloride, etc., just like the first screen sheet 21. The front surface of the second screen sheet 51 is white so as to reflect the image light. The second screen sheet 51 may be colored white by a white coating. The thickness of the second screen sheet 51 may be the same as the thickness of the first screen sheet 21. However, the second screen sheet 51 does not need to be made of the same material as the first screen sheet 21. 【0076】 [Second Light-Blocking Film] The second light-blocking film 52 is placed on the back of the second screen sheet 51 to improve the reflectivity of the image light. The second light-blocking film 52 also blocks the incidence of external light from the back of the second screen sheet 51. The second light-blocking film 52 may be formed from, for example, a metal foil or a metal vapor-deposited film. The second light-blocking film 52 may be aluminum foil. The thickness of the second light-blocking film 52 may be the same as the thickness of the first light-blocking film 22. However, the second light-blocking film 52 does not need to be made of the same material as the first light-blocking film 22. 【0077】 Preferably, at least the front side of the second light-shielding film 52 has specular reflection properties. According to this embodiment, light leaking from the second screen sheet 51 to the back side can be reflected, improving the visibility of the image projected onto the second screen sheet 51. 【0078】 [Magnetic Sheet] The magnetic sheet 53 is placed, for example, on the back of the closing member 42. The closing member 42 is attached to the front of the panel 61 by the magnetic sheet 53. In this configuration, the closing member can be easily attached to and detached from the panel 41 by magnetic force without using adhesive or double-sided tape. 【0079】As shown in Figure 12, the closing member 42 may be partially fixed to at least some of the panels 61 among the plurality of panels 61. According to this embodiment, the closing member 42 can be handled integrally with the panel 61, thereby improving the handling of the screen device 70. The closing member 42 may be fixed, for example, along the lower edge of the panel 61. According to this embodiment, in the process of raising the other members 101 and deploying the panel group 67a to 67d, the closing member 42 fixed to the upper panel 61 can easily close the gap between it and the lower panel 61. 【0080】 (Panel) As described above, the panel 61 has magnets 41a. The magnets 41a may be embedded in the front surface of the base material. The magnets 41a are provided in the portion that overlaps with the magnetic sheet 53 when viewed from the front in the state formed as a suspended screen. As shown in Figures 9 and 12, the panel 61 may have magnets 41a that can be attached to and detached from the magnetic sheet 53 in the peripheral portion when viewed from the front. According to this embodiment, the planar area of ​​the closing member 42 is reduced, improving the handling of the closing member 42, while the gap between the front surfaces of adjacent panels 61 can be easily closed by the closing member 42. Note that having magnets in the "peripheral portion" means that magnets are provided in at least a part of the peripheral portion. For example, magnets 41a may be provided in the four corners of the panel 61, magnets 41a may be provided in the entire peripheral portion of the panel 61, or magnets 41a may be provided in the entire peripheral portion other than the corners. In addition, the magnets 41a may be provided in parts of the panel 61 other than the peripheral portion when viewed from the front. 【0081】[Method for forming a suspended screen] The method for forming a suspended screen using the screen device 70 shown in Figure 9 (hereinafter also simply referred to as "the forming method") involves connecting a connecting portion 65 provided on the uppermost panel 62 to another member 101 (connecting step), and raising the other member 101 (raising step). In the raising step, the gap between the front faces of adjacent panels 61 is closed with a closing member 42. In the raising step, for example, the other member 101 is raised to unfold a plurality of panels 61 included in each panel group 67a to 67d, and the closing member 42 is attached to the front of the panel 61 so as to close the gap between the front faces of adjacent panels 61. In the raising step, the raising of the other member 101 and the attachment of the closing member 42 may be performed in parallel or alternately. The forming method can be carried out in the same procedure as the forming method in the first embodiment, except that the gap between the front faces of adjacent panels 61 is closed with a closing member 42 in the raising step. 【0082】 [Method for disassembling a suspended screen] The method for disassembling a suspended screen formed using the screen device 70 of Figure 9 (hereinafter also simply referred to as "the disassembly method") involves lowering other members 101 (lowering step) and removing the connecting portion 65 provided on the uppermost panel 62 from the other members 101 (removal step). In the lowering step, the closing member 42 that closes the gap between the front surfaces of adjacent panels 61 is removed from the panel 61. In the lowering step, for example, while removing the closing member 42 from the panel 61, the other members 101 are lowered to fold the multiple panels 61 included in each panel group 67a to 67d. In the lowering step, the removal of the closing member 42 and the lowering of the other members 101 may be performed in parallel or alternately. The disassembly method can be carried out in the same procedure as the disassembly method in the first embodiment, except that the closing member 42 is removed from the panel 61 in the lowering step. 【0083】[Third Embodiment] <Suspended Screen Device> The suspended screen device 1 shown in Figure 13 (hereinafter also simply referred to as "screen device 1") comprises a suspension member 3 that can be suspended from another member 100, and a plurality of panels 2 that are configured as a screen when suspended from the other member 100 via the suspension member 3. The plurality of panels 2 are detachably arranged on the suspension member 3. As shown in Figure 14, each of the plurality of panels 2 has a mounting portion 11 that can be attached to the suspension member 3. As shown in Figure 15, the suspension member 3 has a mounting portion 12 to which the mounting portion 11 can be attached, and a connecting portion 13 that can be connected to the other member 100 so that it can be suspended from the other member 100. The connecting portion 13 is detachably connected to the other member 100. The plurality of panels 2 are configured as a screen when arranged on the suspension member 3. The plurality of panels 2 may be configured as a flat screen or as a curved screen. 【0084】 The screen device 1 is assembled into a suspended screen at the venue for use, such as an event or exhibition, and disassembled from the suspended screen after use at the venue. The screen device 1 is assembled into a suspended screen by connecting the connection part 13 of the suspension member 3 to the horizontal bar (other member 100) of the batten device at the venue, and arranging multiple panels 2 on the suspension member 3 in this state. The screen device 1 can be easily assembled into a suspended screen and disassembled from the suspended screen by attaching and detaching the mounting part 11 of the panel 2 and the mounting part 12 of the suspension member 3. In addition, the screen device 1 can be transported and stored separately from the multiple panels 2 and the suspension member 3. Therefore, the screen device 1 is easy to handle. 【0085】 The screen device 1 does not require a frame or stand to support the multiple panels 2. Therefore, the screen device 1 is lightweight and easy to handle. Furthermore, because it does not require the aforementioned frame or stand, it is easy to transport. 【0086】The screen device 1 allows for changes in the number and arrangement of panels 2 depending on the usage scenario. The area of ​​the screen formed using the screen device 1 can be the same as the area of ​​the screen in the first embodiment. 【0087】 (Panel) Panel 2 is itself an embodiment of the present disclosure. Panel 2 according to an embodiment of the present disclosure is used in a suspended screen device 1 and has a mounting portion 11 on its back that is detachably attached to a mounting portion 12 of a suspension member 3. Panel 2 can improve the handling of the suspended screen device 1. 【0088】 Multiple panels 2 may form a single planar screen by arranging them adjacent to each other with their front faces facing the same virtual plane. The shapes of the multiple panels 2 may be the same or different. The screen device 1 is easier to handle if the multiple panels 2 have the same shape. The panels 2 may be rectangular in front view. In particular, the screen device 1 may have two or more panels 2 that are rectangular and identical in front view, and all panels 2 included in the screen device 1 may be rectangular and identical in front view. In the following, we will describe the case where all panels 2 are rectangular and identical in front view. 【0089】As shown in Figure 16, the panel 2 has a first screen sheet 21, a first light-shielding film 22, and a substrate 23. The panel 2 may have the first screen sheet 21, the first light-shielding film 22, and the substrate 23 in this order from the front to the back. The panel 2 may also have a pair of first light-shielding films 22 and a pair of first screen sheets 21 sandwiching the substrate 23. For example, the panel 2 may have a three-layer structure of the first screen sheet 21, the first light-shielding film 22, and the substrate 23 from the front to the back, or it may have a five-layer structure of the first screen sheet 21, the first light-shielding film 22, the substrate 23, the first light-shielding film 22, and the first screen sheet 21 from the front to the back. Furthermore, as described in the first embodiment, the panel 2 may have the first screen sheet 21, the first light-shielding film 22, the substrate 23, the back-side light-shielding film 68, and the reinforcing sheet 69 from the front to the back. The first screen sheet 21, the first light-shielding film 22, the base material 23, the back side light-shielding film 68, and the reinforcing sheet 69 may be fixed together with an adhesive. 【0090】 The laminate, which includes the first screen sheet 21, the first light-shielding film 22, and the base material 23, constitutes the panel body 20. The panel body 20 is less prone to warping because it has a pair of first light-shielding films 22 and a pair of first screen sheets 21 sandwiching the base material 23. In the panel body 20, the first screen sheet 21, the first light-shielding film 22, and the base material 23 may be indirectly laminated with another member in between, but it is preferable that they be directly laminated. The first screen sheet 21, the first light-shielding film 22, the base material 23, the back-side light-shielding film 68, and the reinforcing sheet 69 are the same as in the first embodiment, so they are denoted by the same reference numerals and their description is omitted. 【0091】 (Mounting portion) As described above, the panel 2 is provided with a mounting portion 11. The mounting portion 11 may be formed on the back surface 20a of the panel body 20, or, as shown in Figure 14, it may be attached to the back surface 20a of the panel body 20 as a separate component from the panel body 20. 【0092】As shown in Figure 14, it is preferable that the panel 2 has mounting portions 11 at horizontally opposing positions on the upper and lower parts of its back surface. According to this embodiment, the panel 2 can be easily and stably attached to the suspension member 3. Furthermore, according to this embodiment, the panel 2 can be easily removed from the suspension member 3. 【0093】 The specific configuration of the mounting portion 11 can be set in correspondence with the configuration of the mounting portion 12 provided on the suspension member 3. The mounting portion 11 may be, for example, a hook, a hook receiving portion that can be hooked onto the hook, a button such as a snap button, a hook-and-loop fastener, or a magnet. Among these, a hook or a hook receiving portion that can be hooked onto the hook is preferred as the mounting portion 11. If the mounting portion 11 is a hook, the mounting portion 12 provided on the suspension member 3 is a hook receiving portion, and if the mounting portion 11 is a hook receiving portion, the mounting portion 12 may be a hook. In other words, in the screen device 1, it is preferable that one of the mounting portion 11 and the mounting portion 12 is a hook. According to this embodiment, the panel 2 can be easily attached to and detached from the suspension member 3, and the panel 2 can be easily and reliably prevented from falling while attached to the suspension member 3. 【0094】 In Figure 14, the mounting portion 11 is a hook receiving portion that can be hooked onto a hook. An example of the mounting portion 11 will be described below based on Figure 14. 【0095】The mounting portion 11 is a separate component from the panel body 20 and is fixed to the back surface 20a of the panel body 20 by fastening means such as adhesive or screws. In a front view, the mounting portion 11 protrudes outward from the side edge of the panel body 20. The mounting portion 11 has a hole 11a for hooking a hook in this protruding portion. The hole 11a is an elongated hole with the vertical direction as its longitudinal direction. Four holes 11a are arranged on the back surface 20a of the panel body 20 by the four mounting portions 11. More specifically, the holes 11a are located near both ends in the horizontal direction at the top of the back surface 20a and near both ends in the horizontal direction at the bottom of the back surface 20a. That is, there is a pair of holes 11a that are horizontally opposite at the top of the back surface 20a of the panel body 20, and a pair of holes 11a that are horizontally corresponding at the bottom of the back surface 20a. 【0096】 (Suspension Member) The suspension member 3 is suspended from other members 100 such as the horizontal bar of the baton device, and multiple panels 2 are positioned in predetermined locations to form a flat screen or the like. In this embodiment, all panels 2 that make up the flat screen or the like are directly attached to the suspension member 3. 【0097】 As shown in Figures 13 and 15, the suspension member 3 includes a plurality of strip-shaped or plate-shaped elongated members 30. The suspension member 3 may have, for example, a connecting member (not shown) connected to the upper ends of the plurality of elongated members 30. In this case, the connecting member may be provided with a connecting portion 13 that connects to other members 100. Alternatively, the suspension member 3 may consist of a plurality of strip-shaped or plate-shaped elongated members 30. In this case, each elongated member 30 may have a connecting portion 13 that connects to other members 100. By including a plurality of strip-shaped or plate-shaped elongated members 30, the suspension member 3 can improve portability and ease of forming a suspended screen. Furthermore, by changing the length and number of the plurality of elongated members 30, the size of a flat screen, etc., can be easily changed. In other words, the screen device 1 significantly improves the degree of freedom in designing the size of a flat screen, etc. 【0098】As an example of the specific configuration of the suspension member 3, a configuration in which the suspension member 3 consists of a plurality of elongated members 30 will be described with reference to Figure 15. 【0099】 The elongated member 30 is in the shape of a strip or a plate. Preferably, the elongated member 30 is configured to be able to be rolled up or folded so that its length is reduced. If the elongated member 30 is in the shape of a strip, it can be rolled up into a roll. As a result, ease of storage and transportation can be improved. If the elongated member 30 is in the shape of a plate, it may be configured to be able to be folded in multiple stages along its longitudinal direction. In this case, folding it during storage and transportation can improve ease of storage and transportation. Note that from the viewpoint of convenience for storage and transportation, a strip shape may be preferable to a plate shape. The elongated member 30 may have a weight 35 at its lower end. Having a weight 35 makes it easier to maintain multiple panels 2 in a desired position. 【0100】 [Connection part] The specific configuration of the connection part 13 is not particularly limited as long as it can be made strong enough to support the weight of the long member 30 and the multiple panels 2 when the multiple panels 2 are arranged on the long member 30. The specific configuration of the connection part 13 can be set according to the shape of the other members 100, but for example it may have a winding part 13a that is wrapped around a horizontal bar and a fixing part 13b for fixing the winding part 13a when it is wrapped around the horizontal bar. The fixing part 13b may be made of hook and loop fasteners, snap buttons, or magnets. 【0101】 [Mounting portion] The elongated member 30 is provided with a plurality of mounting portions 12 spaced apart in the longitudinal direction. The specific configuration of the mounting portions 12 can be set in accordance with the configuration of the mounting portion 11 described above. That is, the mounting portions 12 may be, for example, hooks, hook receiving portions that can be hooked onto hooks, buttons such as snap buttons, hook-and-loop fasteners, or magnets. 【0102】The mounting portion 12 is provided in a one-to-one correspondence with the mounting portion 11 provided on the panel 2. An example of the mounting portion 12 will be described with reference to Figures 15, 17, and 18. 【0103】 In Figures 15, 17, and 18, the mounting portion 12 is a hook. The mounting portion 12 has a groove 12a into which the mounting portion 11 fits. As shown in Figure 17, the groove 12a has an insertion portion 31 into which the mounting portion 11 is inserted, and a narrow portion 32 positioned towards the tip in the depth direction of the insertion portion 31. The narrow portion 32 functions as a holding portion that holds the mounting portion 11. The mounting portion 12 also has a retaining portion 33 that covers a part of the opening of the groove 12a so as to cover the vertically above the narrow portion 32. The retaining portion 33 prevents the mounting portion 11, which is held in the narrow portion 32, from coming out vertically upward from the groove 12a. By having the narrow portion 32 and the retaining portion 33, the mounting portion 12 can easily and reliably prevent the panel 2 from falling from the suspension member 3. 【0104】 Furthermore, the mounting portion 12 may have, together with or with both the narrow portion 32 and the retaining portion 33, or in place of the narrow portion 32 and the retaining portion 33, an elastic body (not shown) that presses the mounting portion 11 against the side edge of the groove portion 12a. This configuration also makes it possible to easily and reliably prevent the panel 2 from falling from the suspension member 3. 【0105】 As shown in Figure 17, the elongated member 30 has mounting portions 12 on both sides in the width direction. In the screen device 1, the multiple elongated members 30 are suspended vertically and arranged with gaps in the horizontal direction. Then, a pair of mounting portions 11 that face each other horizontally in the panel 2 are attached to the mounting portions 12 of a pair of horizontally adjacent elongated members 30. 【0106】As shown in Figure 13, the screen device 1 comprises at least one pair of panels arranged adjacent to each other in the horizontal direction. Furthermore, as shown in Figure 18, the elongated member 30 has a mounting portion 12 on one side in the width direction to which the mounting portion 11 of one of the pair of panels 2 (first panel 2a) can be attached, and a mounting portion 12 on the other side in the width direction to which the mounting portion 11 of the other panel of the pair of panels 2 (second panel 2b) can be attached. This configuration makes it easy to arrange multiple panels 2 closely together. As a result, a high-quality suspended screen can be easily formed. 【0107】 Multiple panels 2 may be attached to multiple elongated members 30 in a matrix (array). The screen device 1 allows multiple panels 2 to be easily attached to multiple elongated members 30 in a matrix by having each elongated member 30 have a pair of attachment parts 12 at positions facing each other in the width direction. According to this embodiment, a planar screen of any size can be easily formed by changing, for example, the length or number of elongated members 30 used. In addition, in this disclosure, it is also possible to intentionally form an opening in a part of the planar screen by not attaching panels 2 in certain areas. According to this embodiment, the range of performances can be broadened. 【0108】 The number of elongated members 30 in the screen device 1 can be selected according to the size of the flat screen, etc., and the lower limit may be 3, 4, 7, or 10. On the other hand, the upper limit of the number of elongated members 30 may be 40 or 35. Similarly, the number of panels 2 aligned in the longitudinal direction of the elongated members 30 can be selected according to the size of the flat screen, etc., and the lower limit may be 3, 4, or 5. On the other hand, the upper limit of the number of panels 2 may be 10, 8, or 7. If the length of the elongated members 30 is large relative to the size of the flat screen, etc., the lower end portion of the elongated members 30 may be bent before use. 【0109】When the panels are positioned on the suspension member 3, gaps may form between adjacent panels 2. In this case, it is preferable that the gaps be small. The smaller the gaps, the less visible they become, allowing the viewer to see the desired image without any discomfort. 【0110】 [Fourth Embodiment] <Suspended Screen Device> The suspended screen device 40 shown in Figure 19 (hereinafter also simply referred to as "screen device 40") comprises a suspension member 3 that can be suspended from another member 100, and a plurality of panels 41 that are configured as a screen when suspended from the other member 100 via the suspension member 3. The screen device 40 also further comprises a closing member 42 that closes the gap between the front surfaces of adjacent panels 41. The suspension member 3 in the screen device 40 can be the same as the suspension member 3 in the screen device 1 of Figure 13, so the same reference numerals are used and the description is omitted. The closing member 42 in the screen device 40 is the same as the closing member 42 in Figures 10 and 11, so the description is omitted. The panels 41 in the screen device 40 can be the same as the panels 2 in the screen device 1 of Figure 13, except that they have magnets 41a as shown in Figure 20. 【0111】 The screen device 40 includes a closing member 42 that closes the gap between the front surfaces of adjacent panels 41, so that the viewer can easily and comfortably view the desired image without any discomfort. 【0112】 (Panel) Panel 41 is itself an embodiment of the present disclosure. As described above, panel 41 has magnets 41a. The arrangement of magnets 41a in panel 41 can be the same as in the screen device 70 of Figure 9. 【0113】[Method for Forming a Hanging Screen] Next, a method for forming a hanging screen according to one aspect of the present disclosure will be described with reference to Figures 21 to 25. The method for forming a hanging screen (hereinafter also simply referred to as "the forming method") is a method for forming a hanging screen comprising a hanging member that can be suspended from another member, and a plurality of panels that are configured as a screen when suspended from the other member via the hanging member. As shown in Figure 21, the forming method involves connecting the connection portion of the hanging member to a horizontal bar (connection step S1), and while raising the horizontal bar, attaching the mounting portion of the panel to the mounting portion of the hanging member (mounting step S2). 【0114】 This formation method can be performed, for example, using the screen device 1 shown in Figure 13 or the screen device 40 shown in Figure 19. This formation method can be performed at the location where the suspended screen is used. The following description will focus on the case using the screen device 1 shown in Figure 13. 【0115】 (Connection Step) In connection step S1, as shown in Figure 22, the connection portion 13 of the suspension member 3 is connected to the horizontal bar 100a of the baton device. In connection step S1, multiple long members 30 are connected to the horizontal bar 100a at equal intervals. It is preferable that connection step S1 be performed with the horizontal bar 100a lowered to a position where an operator can work on the stage 200. It is also preferable that when connection step S1 is completed, the horizontal bar 100a is in a state where the uppermost and the next uppermost attachment portion 12 provided on the long members 30 are suspended above the stage 200. 【0116】(Mounting Step) As shown in Figure 23, in mounting step S2, first the mounting portion 11 of the panel 2 is attached to the mounting portion 12 which is suspended above the stage 200. In mounting step S2, multiple panels 2 are attached to the suspension member 3. In mounting step S2, multiple panels 2 may be attached in parallel in the horizontal direction. When the screen device 40 of Figure 19 is used in this forming method, in mounting step S2, the mounting portion 11 of the panel 41 is attached to the mounting portion 12 of the suspension member 3, and the gap between the front surfaces of adjacent panels 41 is closed with the closing member 42. 【0117】 Next, in the mounting step S2, as shown in Figure 24, the horizontal bar 100a is raised and the mounting portion 11 of the panel 2 is attached to the mounting portion 12 which has been newly lifted above the stage 200. 【0118】 In installation step S2, the raising of the horizontal bar 100a and the installation of the panel 2 (or the panel 41 and the closing member 42) may be performed in parallel or alternately. In installation step S2, the raising of the horizontal bar 100a and the installation of the panel 2 (or the panel 41 and the closing member 42) are performed until a flat screen of the desired size is formed. As a result, a suspended screen is formed. 【0119】 According to this forming method, a suspended screen can be easily formed. In particular, since this forming method does not require specialized knowledge to form a suspended screen, anyone can easily form one. Furthermore, according to this forming method, the worker only needs to sequentially attach the panels 2 (or the panels 41 and the closing members 42) to the suspension members 3 on the stage 200, and there is no need to spread the equipment across the entire stage 200, so a suspended screen can be easily formed in a small space. Moreover, according to this forming method, multiple workers can attach multiple panels 2 simultaneously, thus shortening the time required to form a suspended screen. 【0120】[Method for disassembling a suspended screen] Next, a method for disassembling a suspended screen according to one aspect of the present disclosure will be described with reference to Figures 25 to 28. The method for disassembling a suspended screen (hereinafter also simply referred to as "the disassembly method") comprises a suspension member that can be suspended from other members, and a plurality of panels that constitute a screen when suspended from the other members via the suspension member, wherein the connection portion of the suspension member is connected to a horizontal bar, and the suspension member is suspended from the horizontal bar. As shown in Figures 26 and 27, the disassembly method involves lowering the horizontal bar and removing the mounting portion of the panel from the mounting portion of the suspension member (removal step S11). Furthermore, after the removal step S11, the disassembly method involves releasing the connection between the connection portion of the suspension member and the horizontal bar (disconnection step S12). Furthermore, if the suspension member can remain connected to the horizontal bar, the disassembly method does not need to include the disconnection step S12. 【0121】 This disassembly method can be performed, for example, using the screen device 1 shown in Figure 13 or the screen device 40 shown in Figure 19. This disassembly method can be performed at the location where the suspended screen is used. The following description will focus on the case using the screen device 1 shown in Figure 13. 【0122】 (Removal Step) As shown in Figure 26, in removal step S11, first, the multiple panels 2 located at the bottom of the suspended screen are removed from the suspension member 3. In this disassembly method, if the screen device 40 shown in Figure 19 is used, in removal step S11, prior to removing the panel 41, the closing member 42 that seals the gap between the front surfaces of adjacent panels 41 is removed from the panel 41. 【0123】 Next, in the removal step S11, as shown in Figure 27, the horizontal bar 100a is lowered so that the worker can work on the stage 200, and the multiple panels 2 located on the second level from the bottom are removed from the suspension member 3. 【0124】In removal step S11, the lowering of the horizontal bar 100a and the removal of the panel 2 (or panel 41 and closing member 42) may be performed in parallel or alternately. In removal step S11, the lowering of the horizontal bar 100a and the removal of the panel 2 (or panel 41 and closing member 42) are performed until all panels 2 (or all panels 41 and all closing members 42) have been removed. 【0125】 (Disconnection step) In disconnection step S12, as shown in Figure 28, with all panels 2 (or all panels 41 and all closing members 42) removed from the suspension member 3, the connection portion 13 of the suspension member 3 is removed from the horizontal bar 100a. 【0126】 According to this disassembly method, no specialized knowledge is required to disassemble the suspended screen, making it easy for anyone to do so. Furthermore, according to this disassembly method, the worker only needs to sequentially remove the panels 2 (or panels 41 and closing members 42) from the suspension members 3 on the stage 200, allowing for easy and space-saving disassembly of the suspended screen. Moreover, according to this disassembly method, multiple workers can remove multiple panels 2 simultaneously, thus shortening the time required to disassemble the suspended screen. 【0127】 [Fifth Embodiment] <Screen Device> A screen device according to another embodiment of the present disclosure comprises a plurality of panels configured as a screen. The plurality of panels include perforated panels having holes penetrating in the thickness direction and a fiber layer covering the holes from the back side. 【0128】Conventional screens, such as the one described in Patent Document 1, do not transmit sound easily, making it difficult to place a sound source on the back side. In contrast, Patent Document 2 describes providing holes in the panel and filling these holes with a porous material. However, there is room for further improvement in this configuration. The screen device in this embodiment was made based on these circumstances, and aims to provide a screen device that can easily and efficiently enhance the sense of presence of images and sounds by transmitting sound from the back side while suppressing a decrease in visibility. 【0129】 The screen device only needs to be able to form a screen using the plurality of panels, and the configuration for arranging the plurality of panels is not particularly limited. For example, the screen device may have any of the configurations shown in Figures 1, 9, 13, and 19, or it may have any other configuration. As an example of any other configuration, for example, it may be a freestanding screen device in which the plurality of panels are arranged in a predetermined frame. A specific example of a configuration in which the plurality of panels are arranged in a predetermined frame is, for example, the configuration described in Patent Document 2 mentioned above. Hereinafter, an embodiment of the screen device having the configuration of Figure 1 will be described with reference to Figures 29 to 31. 【0130】 The screen device 80 comprises a plurality of panels 81 that are suspended from other members 101 and configured as a screen. As shown in Figures 30 and 31, the plurality of panels 81 include perforated panels 82 having holes 82a that penetrate in the thickness direction and a fiber layer 84 that covers the holes 82a from the back side. The plurality of panels 81 also include one or more normal panels 83 that do not have holes 82a and a fiber layer 84. 【0131】Since the screen device 80 includes a perforated panel 82, when a sound source is placed on the back side of the screen, sound can be transmitted through the holes 82a. Furthermore, since the perforated panel 82 is covered from the back side by a fiber layer 84, it is possible to suppress obstruction of sound transmission through the holes 82a while suppressing a decrease in the visibility of the image (unnatural appearance of the image). As a result, the screen device 80 can improve the sense of realism of sound while suppressing a decrease in the visibility of the image. 【0132】 (Perforated Panel) The perforated panel 82 can have the same configuration as the panel 61 in the screen device 60 of Figure 1, except that it has holes 82a that penetrate in the thickness direction and a fiber layer 84. That is, the perforated panel 82 may have, for example, a first screen sheet 21, a first light-shielding film 22, and a base material 23 in this order from the front side to the back side, and may further have a back side light-shielding film 68 and a reinforcing sheet 69 on the back side of the base material 32, and may have a pair of first light-shielding films 22 and a pair of first screen sheets 21 sandwiching the base material 23. 【0133】 The diameter of the holes 82a formed in the perforated panel 82 can be any size that is difficult for the viewer to see, for example, 1 mm or more and 10 mm or less. The lower limit of the diameter of the holes 82a can be 2 mm or 4 mm. On the other hand, the upper limit of the diameter of the holes 82a can be 8 mm or 6 mm. 【0134】 The arrangement and number of holes 82a in the perforated panel 82 can be set according to the usage environment, etc. For example, the perforated panel 82 does not need to have multiple holes 82a all over its surface; it may have multiple holes 82a only in a part of the front view. 【0135】 The material of the fiber layer 84 placed on the perforated panel 82 may be, for example, fabric, or a highly sound-transmitting material such as a porous material like sponge. If the material of the fiber layer 84 is fabric, it is easier to suppress the reduction in the visibility of the image while suppressing interference with sound transmission. 【0136】As shown in Figure 30, the fiber layer 84 may be positioned at the very back of the perforated panel 82. The front surface of the fiber layer 84 may be a flat surface that closes the opening on the back side of the hole 82a. On the other hand, as shown in Figure 31, the fiber layer 84 may have a flat portion 84a positioned on the back of the perforated panel 82 and a convex portion 84b that protrudes from the flat portion 84a and fills the hole 82a. According to this embodiment, the hole 82a becomes less visible to the viewer, and the adhesion of the fiber layer 84 to the panel body can be improved. As a result, the decrease in the visibility of the image can be suppressed more reliably. Note that the convex portion 84b does not need to completely fill the inside of the hole 82a, but may only fill a part of the back side of the hole 82a. Means for filling the holes 82a with fibrous material 84 to form the protrusions 84b include, for example, pressing the fibrous layer 84 against the back side of the holes 82a to press-fit the fibrous layer 84 into the holes 82a, or arranging protrusions corresponding to the positions of the holes 82a on the back side of the fibrous layer 84 and fitting the protrusions into the holes 82a while sandwiching the fibrous layer 84. When fitting the protrusions, a press mold having multiple protrusions corresponding to the positions of multiple holes 82a may be used. 【0137】 As described above, the plurality of panels 81 include two types of panels: perforated panels 82 and normal panels 83. The screen device 80 can achieve both high screen resolution and high sound transmission by arbitrarily arranging these two types of panels. In this case, it is preferable to arrange the perforated panels 82 in front of sound-emitting devices such as speakers. It is also preferable to arrange the normal panels 83 in areas other than in front of the sound-emitting devices. In other words, in the screen device 80, it is preferable that the plurality of panels 81 include one or more perforated panels 82 and one or more normal panels 83, which are arranged according to the positions of one or more sound-emitting devices arranged on the back side of the screen. 【0138】 [Other Embodiments] The embodiments described above do not limit the configuration of the present invention. Therefore, the embodiments may omit, substitute, or add components of each part of the embodiments based on the description herein and common technical knowledge, and all such additions should be interpreted as falling within the scope of the present invention. 【0139】 In the above embodiment, a configuration in which the connecting portion has a shaft member was described. On the other hand, if each panel has a connecting portion that can be connected to other panels adjacent in the vertical direction, for example as shown in Figure 32, the connecting portion 94 may be connected to other panels 91 adjacent in the vertical direction via a long member 95 that extends in the vertical direction. In Figure 32, the connecting portions 94 provided on panels 91 adjacent in the vertical direction are indirectly connected to each other via another member (long member 95). That is, each of the multiple panels 91 has a connecting portion 94 that can be connected to a long member 95. The long member 95 has a connected portion to which the connecting portion 94 is connected. The specific configuration of the connected portion is not particularly limited, but it may be a portion that is sandwiched by the connecting portion 94, or a portion that is bonded to the connecting portion 94. The material of the long member 95 is not particularly limited. However, it is preferable that the long member 95 be flexible. Also, the long member 95 may also serve as a connecting portion for connecting the uppermost panel to other members (horizontal bars). The number and arrangement of connecting parts 94 on panel 91 are not particularly limited, but the connecting parts 94 may be provided on both sides in the width direction at the upper part of the back surface of panel 91, for example, as shown in Figure 32. With this configuration in which the connecting parts 94 are connected to other panels 91 via elongated members 95, the load of each panel 91 is applied to the elongated members 95. As a result, the panel 91 positioned above does not need to support the panel 91 below, thus increasing the design flexibility of the panels 91 and the overall durability of the screen device. The elongated members may be preferably in the shape of a strip, from the viewpoint of being easy to conform to the back surface of the panel and having flexibility. 【0140】Furthermore, if each panel has a connecting portion that can be connected to other panels adjacent in the vertical direction, as shown in Figure 33, the connecting portion 96 may have an annular portion 96a that protrudes from at least one of the upper and lower parts of the back surface of the panel 91. The annular portion 96a is formed at the end of a long member that is fixed to the back surface of the panel 91 and extends in the vertical direction. For example, the annular portion 96a is an annular part formed by folding back and sewing the end of a long member. In Figure 33, the annular portions 96a provided on vertically adjacent panels 91 are indirectly connected via another member (connecting member 96b). That is, each of the multiple panels 91 has an annular portion 96a that can be connected to the connecting member 96b. The connecting member 96b has a connected portion 96c to which the annular portion 96a is connected. The connected portion 96c may be, for example, a shaft portion inserted into the annular portion 96a. In Figure 33, the annular portions 96a of a pair of vertically adjacent panels 91 are arranged facing each other, and the annular portions 96a may be rotatably connected to the connecting member 96b. In this embodiment, vertically adjacent panels 91 are connected to each other in a way that allows them to be easily folded, as a result of their respective annular portions 96a being connected to the connecting member 96b. Also in Figure 33, the annular portions 96a are configured to be detachably attached to the connecting member 96b. In this embodiment, the vertical length of the panel group can be changed depending on the place of use, etc. The position and number of connecting portions 96 can be adjusted as appropriate according to the size and weight of the panels 91, etc. Furthermore, the specific shape and material of the connecting member 96b are not particularly limited, as long as it can be connected to the annular portion 96a. In addition, for example, in the uppermost panel, the upper end of the long member may be configured as a connecting portion for connecting the uppermost panel to other members (horizontal bars). 【0141】In the above embodiment, a configuration was described in which the closing member is a sheet member that can be attached to multiple panels. However, in this disclosure, it is also possible to connect multiple panels adjacent in the vertical direction with the closing member. In this case, the closing member also serves as a connecting part. In this suspended screen device, for example, the closing member can serve as a connecting part by increasing the strength of the closing member. According to this embodiment, the number of parts can be reduced, thereby improving handling. In addition, the formation and disassembly of the suspended screen device can be made easier. 【0142】 When forming a screen using a suspended screen device, if multiple panels include the aforementioned perforated panels, the arrangement of perforated panels and normal panels in the entire screen may be determined based on information about the sound-emitting device installed at the screen's usage location (such as a drawing showing the arrangement of the sound-emitting device). In other words, a method for forming a suspended screen according to one aspect of this disclosure may include a step of determining the arrangement of perforated panels and normal panels based on information about the sound-emitting device before the aforementioned connection step. 【0143】 The configurations in each of the embodiments described above can be arbitrarily replaced as long as the effects of this disclosure are achieved. For example, in the configuration of the first or second embodiment, the multiple panels may be arranged in a matrix, or they may be arranged so that a part of the screen has an opening. 【0144】 In the above embodiment, a configuration was described in which multiple panels are directly attached to a suspension member. On the other hand, the screen device can also be configured so that some of the panels are attached to the suspension member. In this case, for example, multiple panels placed on the top row may be attached to the suspension member, and multiple panels placed below that may be directly attached to the panel placed directly above them. With this configuration, multiple panels placed on rows other than the top row will be placed on the suspension member via other panels. Even with this configuration, the screen device offers excellent handling. 【0145】The suspension member may also be configured without including multiple strip-shaped or plate-shaped elongated members. For example, the suspension member may include a single sheet member, and multiple panels may be arranged on this sheet member. Furthermore, if the panels are directly attached to each other as described above, the suspension member may not include any elongated members. However, from the viewpoint of improving handling, it may be preferable for the suspension member to include multiple strip-shaped or plate-shaped elongated members. 【0146】 The arrangement of the mounting portion on the panel is not limited to the arrangement described in the embodiment. For example, the mounting portion may be located on a surface other than the back of the panel. As an example, the mounting portion may be located on the side of the panel. In this case, the mounting portion may be located on both sides of the elongated member, and a pair of panels may be arranged so as to sandwich the elongated member between their sides. That is, the elongated member may have a mounting portion on one side in the thickness direction to which the mounting portion of one of the pair of panels is attached, and a mounting portion on the other side in the thickness direction to which the mounting portion of the other panel of the pair is attached. In this case, it is preferable that the closing member be arranged to close the gap between the front surfaces of the pair of panels. 【0147】 Furthermore, the panel may have a pair of mounting parts only at horizontally opposing positions on the upper part of its back surface. Also, the arrangement of the mounting parts on the elongated member can be set according to the positions of the mounting parts on multiple panels, the shapes of the multiple panels, etc. 【0148】 This screen device is suitable for arranging multiple panels in a matrix. However, the shape and arrangement of the multiple panels can be changed depending on the application of the suspended screen. This screen device offers high flexibility in the overall shape and size of the screen. 【0149】In the above embodiment, a configuration in which the mounting part is a hook and the mounting part is a hook receiving part was described as a specific example. In this regard, when the mounting part is a hook and the mounting part is a hook receiving part in the screen device, the specific shapes of the hook and the hook receiving part can be the same as in the above embodiment. Furthermore, the shapes of the hook and the hook receiving part may differ from the shapes of the above embodiment. 【0150】 In the above embodiment, a configuration in which the closing member is a sheet member was described. On the other hand, in the screen device, it is also possible to provide the closing member integrally (inseparably) with the front surface of the panel. 【0151】 The layer structure and optical properties of the panel and the closure member can be modified according to the application. For example, the closure member can be configured without a magnetic sheet. In this case, the closure member can be attached to the panel by means other than magnetic force. 【0152】 The panel may have a third screen sheet in front of the first screen sheet. The third screen sheet has the same optical properties as the first screen sheet. The third screen sheet may have a smaller area than the first screen sheet. In this case, when the panel is viewed from the front, the first screen sheet is exposed from the outer periphery of the third screen sheet. According to this embodiment, for example, by placing a closure member in the portion where the first screen sheet is exposed, the difference in height between the front of the panel and the front of the closure member can be reduced. As a result, it becomes easier for the viewer to see the desired image without discomfort. 【0153】The panel may have a plurality of holes that penetrate in the thickness direction. In this embodiment, the back and front of the panel can be acoustically connected. As a result, when a speaker is placed behind the flat screen, the sound output from the speaker reaches the front of the flat screen through the holes. Therefore, the viewer can experience sound coming from the front of the flat screen in addition to the image projected onto the flat screen. The holes may be filled with a porous material such as nonwoven fabric or sponge. The porous material may be selected from a material that does not obstruct the passage of sound through the holes. Furthermore, the porous material may have the same optical properties as the first screen sheet. In this embodiment, the viewer can experience sound, and it is easier for the viewer to see the desired image without any discomfort. 【0154】 The screen device may further include actuators positioned on the back side of the plurality of panels. Examples of such actuators include piezoelectric vibrators and motor vibrators. The actuators vibrate the panels in response to an input sound signal. As a result, the panels function as speakers. 【0155】 The screen device may be configured such that the peripheral portions of adjacent panels overlap when viewed from the front. This configuration makes it easier to prevent gaps from forming between adjacent panels. 【0156】1, 40, 60, 70, 80 Hanging type screen device (screen device) 2, 41, 61, 81, 91 Panel 2a First panel 2b Second panel 3 Hanging member 11 Mounting part 11a Hole 12 Mounted part 12a Groove 13 Connection part 13a Winding part 13b Fixing part 20, 66 Panel body 20a Back surface 21 First screen sheet 22 First light-shielding film 23 Base material 30 Long member 31 Insertion part 32 Narrow part 33 Retaining part 35 Weight 41a Magnet 42 Closure member 51 Second screen sheet 52 Second light-shielding film 53 Magnetic sheet 62 Top panel 63 Bottom panel 63a Bottom panel 63b Surplus panel 64, 94, 96 Connecting part 64a Shaft member 64b, 96b Connecting member 64c, 96c Connected part 65 Connecting part 67a, 67b, 67c, 67d Panel group 68 Back side light-shielding film 69 Reinforcement sheet 82a Hole 82 Perforated panel 83 Normal panel 84 Fiber layer 84a Flat part 84b Convex part 95 Long member 96a Annular part 100, 101 Other members 100a Horizontal bar 200 Stage 201 Floor surface
