  Hereinafter, embodiments will be described with reference to the drawings. In the drawings attached to the present specification, for the sake of illustration and ease of understanding, the scale, the vertical / horizontal dimension ratio, and the like are appropriately changed and exaggerated from those of the actual product. In addition, as used in this specification, the shape and geometric conditions and the degree thereof are specified, for example, terms such as “parallel”, “orthogonal”, “identical”, length and angle values, etc. are strictly Without being bound by meaning, it should be interpreted including the extent to which similar functions can be expected.

  1 to 9 are diagrams for explaining an embodiment. 1 and 2 are perspective views or longitudinal sectional views showing the configuration of the solar cell composite display body 10, and FIGS. 3 to 5 are diagrams for explaining the operation of the solar cell composite display body 10. FIG. 6-8 is a figure for demonstrating an example of the manufacturing method of the solar cell composite display 10, and FIG. 9 is a figure for demonstrating the frame member 70. As shown in FIG.

  The solar cell composite display 10 described here exhibits both a predetermined display function and a power generation function using external light. In the solar cell composite display 10 shown in FIGS. 1 and 2, the plurality of orientation adjustment surfaces 21 and the plurality of light transmission surfaces 22 alternately arranged in the first axis direction d <b> 1 are more incident than the solar cell panel 50. On the side. When the solar cell composite display body 10 is observed from the direction D21 within a certain angle range AR1, the display surface 12 disposed mainly on the orientation adjustment surface 21 is observed. Therefore, the display surface 12 exhibits a display function for an observer who observes the solar cell composite display body 10 from a certain angle range AR1. On the other hand, the light L22 incident from a direction within another certain angular range AR2 mainly passes through the light transmission surface 22 and is guided to the solar cell panel 50. Therefore, the solar cell panel 50 exhibits a power generation function with respect to light incident on the solar cell composite display body 10 from another certain angular range AR2. Thus, according to the solar cell composite display 10, the solar cell panel 50 is used when the observer observes the display surface 12 by utilizing the difference between the observation direction from the observer and the incident direction of the external light. Visibility is suppressed and it is possible to achieve harmony with the surroundings.

  Hereinafter, the configuration and operational effects of the solar cell composite display 10 according to the present embodiment will be described in detail. As well shown in FIGS. 1 and 2, the solar cell composite display 10 includes a sheet-like sheet member 20, a solar cell panel 50 disposed on the back surface of the sheet member 20, and at least a solar cell panel. And a frame member 70 that holds 50. The frame member 70 will be described later with reference to FIG.

  The sheet-like sheet member 20 has a first surface 20a and a second surface 20b as a pair of main surfaces facing each other. The first surface 20 a forms an incident surface for external light such as sunlight that enters the solar cell composite display 10. Further, the first surface 20 a forms an emission surface from which light from the display surface 12 that visualizes the display target 13 (see FIG. 3) is emitted from the solar cell composite display body 10. On the other hand, the second surface 20 b is a surface facing the solar cell panel 50.

  The second surface 20b of the sheet member 20 includes a plurality of orientation adjustment surfaces 21 and a plurality of light transmission surfaces 22 that are alternately arranged in the first axial direction d1. A display surface 12 for displaying the display target 13 is disposed on the orientation adjustment surface 21. The orientation adjusting surface 21 is provided to support the display surface 12 and adjust the viewing angle at which the display surface 12 can be observed. On the other hand, the light transmission surface 22 is provided to transmit the light L22 incident on the solar cell composite display body 10 between the adjacent display surfaces 12 and guide the light L22 to the solar cell panel 50. In the illustrated example, the plurality of orientation adjustment surfaces 21 are configured identically, and the plurality of light transmission surfaces 22 are also configured identically.

  In the present specification, terms such as “sheet”, “film”, and “plate” are not distinguished from each other only based on the difference in names. Therefore, for example, a “sheet” is a concept including a member that can also be called a film or a plate.

  Further, in this specification, the “sheet surface (film surface, plate surface, panel surface)” is the plane of the target sheet-like member when the target sheet-like member is viewed as a whole and globally. A surface that matches the direction. In the embodiment described below, the sheet surface of the sheet member 20, the panel surface of the solar cell panel 50, and the light receiving surface 50a of the solar cell panel 50 are parallel to each other. Furthermore, in this specification, the “normal direction” used for a sheet-like (film-like, plate-like, panel-like) member refers to a normal direction to the sheet surface of the member.

  As shown in FIG. 1, each orientation adjustment surface 21 and each light transmission surface 22 extend linearly in a direction that intersects the first axial direction d <b> 1 that is the arrangement direction thereof. In particular, in the illustrated example, each orientation adjustment surface 21 and each light transmission surface 22 extend linearly in a second axial direction d2 orthogonal to both the first axial direction d1 and the normal direction nd of the sheet member 20. ing. In the example shown in FIG. 2, each orientation adjusting surface 21 and each light transmitting surface 22 are arranged so as to be shifted from each other when viewed from the normal direction nd. In the present embodiment, the first axial direction d1 and the second axial direction d2 are along the sheet surface of the sheet member 20, and are orthogonal to the normal direction nd of the sheet member 20. In the illustrated example, the solar cell composite display body 10 is arranged such that the first axial direction d1 is parallel to the vertical direction and the second axial direction d2 is parallel to the horizontal direction.

  Each orientation adjusting surface 21 is inclined with respect to the sheet surface of the sheet member 20, in other words, the panel surface of the solar cell panel 50, and is also inclined with respect to the normal direction nd of the sheet member 20. That is, each orientation adjustment surface 21 is not parallel to both the sheet surface of the sheet member 20 and the normal direction nd of the sheet member 20. A viewing angle at which the display object 13 provided on the display surface 12 can be observed by inclining the display surface 12 disposed on the orientation adjustment surface 21 together with the orientation adjustment surface 21 with respect to the panel surface of the solar cell panel 50. The first angle range AR1 can be adjusted with a high degree of freedom.

  As shown in FIG. 2, each orientation adjustment surface 21 has one end portion 21 a located on one side (the upper side in FIG. 2 and the upper side in the vertical direction) in the first axial direction d <b> 1 in the first axial direction d <b> 1. The sheet member 20 is separated from the solar cell panel 50 in the normal direction nd of the sheet member 20 with respect to the other end portion 21b located on the other side (the lower side in FIG. 2 and the lower side in the vertical direction). It is inclined with respect to the seat surface. As can be understood from FIG. 2, such an orientation adjusting surface 21 makes it easier for light to be emitted toward an angle range inclined to the other side with respect to the normal direction nd. That is, the display function from the display surface 12 arranged on the orientation adjustment surface 21 is effectively exhibited when observed from the direction D21 inclined to the other side with respect to the normal direction nd.

  The display surface 12 is disposed along the direction adjustment surface 21 so as to overlap the direction adjustment surface 21. Therefore, the display surface 12 disposed on the orientation adjustment surface 21 also has a sheet having one end 12a positioned on one side in the first axial direction d1 rather than the other end 12b positioned on the other side in the first axial direction d1. The member 20 is inclined with respect to the sheet surface of the sheet member 20 so as to be separated from the solar cell panel 50 in the normal direction nd of the member 20.

  The light emitted from the solar cell composite display 10 toward the first angle range AR1 from the display surface 12 makes the display target 13 applied to the display surface 12 visible. That is, the display surface 12 is visually recognized from the first angle range AR1, and as a result, the display target 13 formed on the display surface 12 can be observed. In addition, when displaying the display object 13 which moves with the display surface 12, it is easy to use the electricity generated from the solar cell panel 50 for driving.

  FIG. 3 shows an example of the display target 13 formed on the display surface 12. A plurality of display surfaces 12 are arranged in the first axial direction d1, and each display surface 12 extends linearly in a second axial direction d2 orthogonal to the first axial direction d1. Therefore, the display surface 12 located at each position in the first axial direction d1 is provided with the display target element 13a corresponding to the position of the display surface 12 in the first axial direction d1, thereby causing the display surface 12 in the second axial direction d2. The two-dimensional display target 13 can be displayed as a combination of the display target elements 13a formed on the elongated display surfaces 12. In the example shown in FIG. 3, the capital letter “N” of the alphabet is displayed as the display target 13. Thus, since the size of each orientation adjustment surface 21 can be reduced by displaying the display target 13 as a combination of a plurality of display target elements 13a, the first angle range AR1 can be expanded or the solar cell composite display body 10 can be reduced. Even if the size is increased, a better display object 13 can be observed.

  As described above, the solar cell composite display body 10 of the present embodiment can adjust the angle range in which the display target 13 is continuously displayed with a high degree of freedom. Therefore, the solar cell composite display body 10 of the present embodiment can be used for various purposes. For example, the solar cell composite display body 10 is several m to several tens of m in size used for outdoor signboards, road information bulletin boards, outer wall surfaces of buildings, and the like. For large panels, medium sized panels for tens of cm to several meters used for posters, signs, inner walls of buildings, etc., and small panels of several centimeters to tens of centimeters used for table lamps, portable terminals, etc. Applications can be exemplified.

  On the other hand, each light transmission surface 22 positioned between the adjacent orientation adjustment surfaces 21 is inclined with respect to the sheet surface of the sheet member 20, in other words, the panel surface of the solar cell panel 50, and the normal direction of the sheet member 20. It is also inclined with respect to nd. That is, each orientation adjustment surface 21 is not parallel to both the sheet surface of the sheet member 20 and the normal direction nd of the sheet member 20. By tilting the light transmission surface 22 with respect to the panel surface of the solar cell panel 50, the second angle range AR2 that is an angle range in which power generation by the solar cell panel 50 is continuously performed stably is increased. It is possible to adjust with a degree of freedom.

  The angle at which the light transmission surface 22 is inclined with respect to the sheet surface of the sheet member 20 is different from the angle at which the direction adjustment surface 21 is inclined with respect to the sheet surface of the light control sheet 20. In particular, in the main cross section of the solar cell composite display shown in FIG. 2, the light transmission surface 22 is inclined to the opposite side of the orientation adjustment surface 21 with respect to the normal direction nd of the sheet member 20. As described above, each orientation adjustment surface 21 is positioned with respect to the sheet surface of the sheet member 20 such that the one end 21a is separated from the solar cell panel 50 in the normal direction nd of the sheet member 20 relative to the other end 21b. Inclined. Accordingly, each light transmission surface 22 has a second end portion 22b positioned on the other side in the first axial direction d1 and a normal direction of the sheet member 20 relative to the first end portion 22a positioned on one side in the first axial direction d1. It is inclined with respect to the sheet surface of the sheet member 20 so as to be separated from the solar cell panel 50 at nd. As can be understood from FIG. 2, light from an angle range inclined to one side with respect to the normal direction nd is easily incident on such a light transmission surface 22. Therefore, the light L22 incident on the solar cell composite display 10 from a direction inclined to one side with respect to the normal direction nd can be easily guided by the solar cell panel 50.

  Next, the relationship between the orientation adjustment surface 21 and the light transmission surface 22 will be described. In the main cross section of the solar cell composite display shown in FIG. 2, the first axial direction d1 of the orientation adjusting surface 21 and the light transmitting surface 22 adjacent to the orientation adjusting surface 21 on the other side in the first axial direction d1. The distance dt along the line becomes narrower stepwise or continuously as it approaches the solar cell panel 50 in the normal direction nd of the sheet member 20. Therefore, the other end 21b of the orientation adjusting surface 21 is closest to the one end 22a of the light transmitting surface 22 located on the other side. In the illustrated embodiment, the other end 21b of the orientation adjusting surface 21 is connected to one end 22a of the light transmitting surface 22 located on the other side. But the other end part 21b of the direction adjustment surface 21 may be spaced apart from the one end part 22a of the light transmission surface 22 located in the other side.

  On the other hand, one end 21a of the orientation adjustment surface 21 is connected to the other end 22b of the light transmission surface 22 adjacent to the orientation adjustment surface 21 on one side in the first axial direction d1. However, the one end portion 21a of the orientation adjustment surface 21 may be separated from the other end portion 22b of the light transmission surface 22 adjacent to the orientation adjustment surface 21 on one side in the first axial direction d1.

  In the main cut surface shown in FIG. 2, the orientation adjustment surface 21 is equal to the length of the light transmission surface 22 adjacent to the orientation adjustment surface 21. Therefore, the ratio of the orientation adjustment surface 21 occupying the second surface 20 b of the sheet member 20 is equal to the ratio of the light transmission surface 22 occupying the second surface 20 b of the sheet member 20. However, in the main cut surface shown in FIG. 2, the orientation adjustment surface 21 may be different from the length of the light transmission surface 22 adjacent to the orientation adjustment surface 21. In particular, when the orientation adjustment surface 21 is shorter than the light transmission surface 22 adjacent to the orientation adjustment surface 21, the ratio of the orientation adjustment surface 21 occupying the second surface 20 b of the sheet member 20 is set to the first of the sheet member 20. It can be made smaller than the ratio of the light transmission surface 22 to the two surfaces 20b. In this case, a relatively large amount of light tends to be easily guided to the light transmission surface 22, and as a result, more light can be contributed to the solar cell panel 50.

  In the example shown in FIG. 2, the angle θ <b> 1 formed by the orientation adjustment surface 21 with respect to the sheet surface of the sheet member 20 is equal to the angle θ <b> 2 formed by the light transmission surface 22 with respect to the sheet surface of the sheet member 20. However, the angle θ1 formed by the orientation adjustment surface 21 with respect to the sheet surface of the sheet member 20 is determined according to the observation direction by the observer intended to be observed, and the light transmission surface 22 is the sheet of the sheet member 20. The angle θ2 formed with respect to the surface is determined in accordance with the incident direction of external light that is intended to be captured. Therefore, the angle θ1 formed by the orientation adjustment surface 21 with respect to the sheet surface of the sheet member 20 may be different from the angle θ2 formed by the light transmission surface 22 with respect to the sheet surface of the sheet member 20.

  Moreover, in the example shown in FIG. 2, each direction adjustment surface 21 and each light transmission surface 22 consist of flat surfaces. However, it is not limited to such an example, and each direction adjustment surface 21 and each light transmission surface 22 may consist of curved surfaces. As an example, each orientation adjustment surface 21 and each light transmission surface 22 may form a part of a spherical surface or a curved surface such as a lens surface. More specifically, each orientation adjusting surface 21 and each light transmitting surface 22 may be lens surfaces curved so as to be convex toward the outer side, or concave toward the inner side. A curved lens surface may be used.

  Similarly, in the example shown in FIG. 2, the display surface 12 is a flat surface. However, it is not limited to such an example, and the display surface 12 may be a curved surface. As an example, each display surface 12 may form a part of a spherical surface or a curved surface such as a lens surface. More specifically, each display surface 12 may be a lens surface curved so as to be convex toward the outer side, or may be a lens surface curved so as to be concave toward the inner side. There may be. In this specification, when the display surface 12 is a curved surface, “the display surface 12 is inclined with respect to the plane” means a straight line connecting both end portions 12a and 12b of the display surface 12 in the main cut surface shown in FIG. Is inclined with respect to the plane.

  An air layer 30 is formed between the second surface 20 b of the sheet member 20 and the solar cell panel 50. In the example shown in FIG. 2, the air layer 30 is formed between the second surface 20 b of the sheet member 20 and the light receiving surface 50 a of the solar cell panel 50. In addition, the sheet | seat member 20 is not limited to the example arrange | positioned through the solar cell panel 50 and the air layer 30, and may be joined via the solar cell panel 50 and the joining layer.

  The solar cell panel 50 includes a light receiving surface 50a facing the second surface 20b of the sheet member 20, a back surface 50b facing the light receiving surface 50a, and a side surface 50c extending between the light receiving surface 50a and the back surface 50b. ing. The solar cell panel 50 is a power generator that converts light received by the light receiving surface 50a into electric energy. Light L22 taken into the light transmission surface 22 from the second angle range AR2 is guided to the light receiving surface 50a of the solar cell panel 50, and this light L22 is used for power generation.

  As shown in FIG. 1, the side surface 50c of the solar cell panel 50 includes a pair of upper and lower side surfaces 50d and 50e facing the first axial direction d1, and a pair of lateral side surfaces 50f facing the second axial direction d2. Is included. Each surface 50d-50f which comprises the side surface 50c is comprised as a flat surface.

  Various types of solar cell panels 50 can be used. For example, a silicon-based solar cell panel, a thin-film solar cell panel, a chalcopyrite solar cell, or the like including a flat silicon substrate made of single crystal silicon or polycrystalline silicon can be used as the solar cell panel 50.

  Next, an example of a method for manufacturing the solar cell composite display 10 described above will be described with reference mainly to FIGS.

  First, as shown in FIG. 6, the sheet member 20 is produced by molding a transparent resin. For the molding, hot-melt extrusion processing, injection molding, or the like can be employed. As shown in FIG. 6, a plurality of orientation adjustment surfaces 21 and a plurality of light transmission surfaces 22 are alternately formed on the second surface 20 b of the obtained sheet member 20.

  Next, as shown in FIG. 7, the display surface 12 is formed on the orientation adjustment surface 21 of the sheet member 20. As an example, the display surface 12 is formed on the orientation adjustment surface 21 of the sheet member 20 by inkjet printing. Thereafter, as shown in FIG. 8, the solar cell panel 50 is disposed to face the second surface 20 b of the sheet member 20. Thereby, the solar cell composite display 10 is obtained.

  Next, the operation of the solar cell composite display 10 will be described mainly with reference to FIGS. 4 and 5. For example, the solar cell composite display 10 is arranged such that the first axial direction d1 that is the arrangement direction of the orientation adjustment surface 21 and the light transmission surface 22 is along the vertical direction. Specifically, the solar cell composite display 10 is arranged such that one side in the first axial direction d1 is along the upper side in the vertical direction and the other side in the first axial direction d1 is along the lower side in the vertical direction. The

  As is well illustrated in FIG. 4, the display surface 12 disposed on the inclined orientation adjustment surface 21 is easily visible from the front direction of the display surface 12. In the example shown in FIG. 4, the display surface 12 is inclined to one side in the first axial direction d1 with respect to the normal direction nd of the sheet member 20, and thus the first axial direction d1 with respect to the normal direction nd. When the solar cell composite display 10 is observed from the directions D41, D42, and D43 inclined to the other side, the display surface 12 is easily visually recognized. In this way, by inclining the orientation adjustment surface 21 with respect to the normal direction nd of the sheet member 20, the first angle range AR1 serving as a viewing angle at which the display surface 12 positioned on the orientation adjustment surface 21 is observed, It can be adjusted with a high degree of freedom. Therefore, the observer can observe the display target 13 with excellent visibility and can display the display target 13 with excellent design.

  On the other hand, the light transmission surface 22 inclined at a different angle from the direction adjustment surface 21 efficiently transmits the light L51, L52, and L53 incident from a direction different from the directions D41, D42, and D43 in which the direction adjustment surface 21 is easily visible. It is possible to capture. In the example illustrated in FIG. 5, the light transmission surface 22 is inclined to the other side in the first axial direction d1 with respect to the normal direction nd of the sheet member 20, and thus the first axial direction with respect to the normal direction nd. Light L51, L52, and L53 incident on the solar cell composite display body 10 from a direction inclined to one side in d1 can be efficiently taken. The lights L51, L52, and L53 taken into the light transmission surface 22 travel through the air layer 30 and are guided to the solar cell panel 50. In this way, the solar cell composite display body that is guided to the solar cell panel 50 by inclining the light transmission surface 22 with respect to the normal direction nd of the sheet member 20 at an angle different from that of the orientation adjustment surface 21. 10 can be adjusted with a high degree of freedom. Therefore, in the solar cell composite display body 10 according to the present embodiment, sunlight that changes the incident direction according to the time zone and season can be efficiently received and used for power generation in the solar cell panel 50. It becomes possible.

  As described above, according to the present embodiment, the sheet member 20 having the first surface 20a and the second surface 20b facing the first surface 20a, and the second surface 20b of the sheet member 20 are disposed opposite to each other. And a plurality of display surfaces 12 that are inclined with respect to the panel surface of the solar cell panel 50 are arranged along the uniaxial direction d1. According to such a solar cell composite-type display body 10, since the display surface 12 is inclined with respect to the panel surface of the solar cell panel 50, the directions D21 and D41 in which the inclined display surface 12 is the front direction. It becomes easy to observe from D43. On the other hand, the light beams L23 and L51 to L53 that are incident on the solar cell composite display body 10 from directions different from the directions D21 and D41 to D43 that allow the display surface 12 to be easily viewed are between the two adjacent display surfaces 12. The light is transmitted and guided to the solar cell panel 50. As described above, the difference between the observation directions D21 and D41 to D43 from the observer and the incident directions of the external lights L23 and L51 to L53 is used to harmonize with the surrounding environment, and display on the display surface 12 and Coexistence of power generation by the solar cell panel 50 is effectively enabled. In addition, since the solar cell panel 50 is disposed to face the second surface 20b of the sheet member 20, the light receiving surface 50a of the solar cell panel 50 is not exposed to the outside. For this reason, the solar cell panel 50 can be made more inconspicuous.

  In addition, according to the present embodiment, the second surface 20b of the sheet member 20 includes the plurality of orientation adjustment surfaces 21 and the plurality of light transmission surfaces 22 that are alternately arranged in the uniaxial direction d1, and the orientation adjustment surface. 21 is inclined with respect to the panel surface of the solar cell panel 50, and the light transmission surface 22 is inclined with respect to the panel surface of the solar cell panel 50 at an angle different from the orientation adjustment surface 21, and is displayed on the orientation adjustment surface 21. Surface 12 is disposed. According to such a form, since the direction adjustment surface 21 and the light transmission surface 22 are inclined with respect to the panel surface of the solar cell panel 50, the inclined direction adjustment surface 21 and the light transmission surface 22 are respectively in front of each other. It becomes easy to effectively use light incident from the direction. In particular, the light transmission surface 22 is inclined with respect to the panel surface of the solar cell panel 50 at an angle different from that of the orientation adjustment surface 21. For this reason, the display surface 12 arranged on the orientation adjustment surface 21 is a solar cell composite display body from the directions D21 and D41 to D43 different from the directions in which the light L22 and L51 to L53 that are easily taken into the light transmission surface 22 are inclined. 10, and the light transmitting surface 22 is incident on the solar cell composite display 10 from a direction different from the directions D21 and D41 to D43 in which the orientation adjusting surface 21 is easily visible. -L53 is taken in effectively. As a result, it is possible to effectively achieve both the display on the display surface 12 and the power generation by the solar cell panel 50.

  By the way, when observing the display object 13 formed on the display surface 12 arranged on the orientation adjustment surface 21, when the solar cell panel 50 is observed through the light transmission surface 22 together with the display object 13, The visibility and designability of the display target 13 will be significantly impaired. Therefore, it is preferable that the first angle range AR1 in which the display surface 12 can be observed is separated from the second angle range AR2 in which the solar cell panel 50 can be observed, that is, does not overlap.

  Therefore, in the solar cell composite display 10 of the present embodiment, the orientation adjustment surface 21 is opposite to the light transmission surface 22 with respect to the normal direction nd of the sheet member 20 in the main cut surface shown in FIG. It is inclined to. According to such a form, the display surface 12 arranged on the orientation adjustment surface 21 is from directions D21 and D41 to D43 opposite to the directions in which the light L22 and L51 to L53 that are easily taken into the light transmission surface 22 are inclined. When the solar cell composite display 10 is observed, it can be easily observed selectively, and the light transmission surface 22 can be seen from the direction opposite to the directions D21 and D41 to D43 where the orientation adjustment surface 21 is easily visible. Lights L22 and L51 to L53 incident on the battery composite display 10 can be selectively captured. Specifically, the orientation adjustment surface 21 is inclined with respect to the sheet surface of the sheet member 20 so that the one end portion 21a is separated from the solar cell panel 50 in the normal direction nd of the sheet member 20 relative to the other end portion 21b. The light transmission surface 22 is inclined with respect to the sheet surface of the sheet member 20 such that the other end portion 22b is separated from the solar cell panel 50 in the normal direction nd of the sheet member 20 relative to the one end portion 22a. . In this case, when the solar cell composite display 10 is observed from the directions D21 and D41 to D43 inclined to the other side in the first axial direction d1 with respect to the normal direction nd of the sheet member 20, from the light transmission surface 22. In addition, the display surface 12 arranged on the orientation adjusting surface 21 can be easily selectively observed. Further, the light L22, L51 to L53 incident on the solar cell composite display body 10 from the direction inclined to one side in the first axial direction d1 with respect to the normal direction nd of the sheet member 20 is more than the direction adjustment surface 21. The light transmission surface 22 can be guided to selection.

  That is, according to such a form, the first angle range AR1 that becomes a viewing angle at which the display surface 12 arranged on the orientation adjustment surface 21 can be observed is the first axis with respect to the normal direction nd of the sheet member 20. The second angle range that corresponds to the direction inclined to the other side in the direction d1 and is the angle range in the incident direction to the solar cell composite display 10 that is guided to the solar cell panel 50 through the light transmission surface 22. AR2 corresponds to a direction inclined to one side in the first axial direction d1 with respect to the normal direction nd of the sheet member 20. In other words, the display surface 12 is observed when the solar cell composite display 10 is observed from the direction inclined to the other side in the uniaxial direction d1, and the solar cell composite display is viewed from the direction inclined to the one side in the uniaxial direction d1. The light incident on 10 passes between two adjacent display surfaces 12 and reaches the solar cell panel 50. In this case, the first angle range AR1 and the second angle range AR2 are easily divided. In other words, the first angle range AR1 and the second angle range AR2 are difficult to overlap.

  As described above, when the overlap between the first angle range AR1 and the second angle range AR2 is reduced, the display function by the display surface 12 and the power generation function by the solar battery panel 50 are more effectively performed without adversely affecting each other. Will come to be. In the present embodiment, it is possible to suppress the observation of the solar cell panel 50 through the light transmission surface 22 together with the display target 13 while observing the display target 13 given to the display surface 12. It becomes possible. In this case, the visibility of the display target 13 and the design of the display target 13 can be improved.

  In particular, in the solar cell composite display 10 according to the present embodiment, the first angle range AR1 serving as a viewing angle at which the display surface 12 can be observed is set in a direction inclined downward in the vertical direction, and the solar cell panel 50 The second angle range AR2 that is the angle range in the incident direction to the solar cell composite display body 10 that is guided to is set in a direction inclined upward in the vertical direction. In this case, it is effective when the solar cell composite display 10 is installed at a position higher than the line of sight in a use as a display plate assumed as a typical use. The observer can observe the display object 13 given to the display surface 12 from the first angle range AR1 in order to observe the solar cell composite display 10 while looking up upward in the vertical direction. On the other hand, although the incident direction of sunlight changes according to the time zone and season, it is incident on the solar cell composite display 10 while proceeding in a direction inclined downward in the vertical direction or in a substantially horizontal direction. For this reason, sunlight can enter the light transmission surface 22 from the second angle range AR2 and travel toward the solar cell panel 50 even if the incident direction changes according to the time zone or season. Therefore, according to such a form, it is possible to effectively achieve both the reception of sunlight by the solar battery panel 50 and the display by the display surface 12.

  Moreover, according to this Embodiment, in the main cut surface of the solar cell composite display 10, the direction adjustment surface 21 and the light transmission surface 22 adjacent to the direction adjustment surface 21 on the other side in the first axial direction d1. The interval dt along the first axial direction d1 becomes narrower as the solar cell panel 50 approaches in the normal direction nd of the sheet member 20. According to such a configuration, the display surface 12 disposed on the orientation adjustment surface 21 blocks light that should be incident on the light transmission surface 22, or the light transmission surface 22 is disposed on the orientation adjustment surface 21. It is possible to effectively suppress the observation of the displayed display surface 12 from being interrupted. For this reason, when the display surface 12 observes the solar cell composite display body 10 from the direction within the first angle range AR1, the display function can be more reliably exhibited. Further, the light transmission surface 22 can more reliably guide the light incident on the solar cell composite display body 10 from the second angle range AR2 to the solar cell panel 50.

  By the way, Table 1 below shows the south-middle altitude (°) for each season in major cities in some countries of the world. It is preferable that the south and middle altitudes of the equinox in the major cities of the country where the use is assumed be included in the second angle range AR2. This is because there is a high possibility that it can be used effectively in that country. For example, when the country assumed to be used is Japan, the altitude from 54 ° to 56 ° may be included in the second angle range AR2. Furthermore, it is preferable that an altitude from 49 ° to 61 ° is included in the second angle range AR2, since there is a high possibility that it can be used effectively in many countries in the world. In addition, it is more preferable that the second angle range AR2 includes a range from the southern middle altitude of the summer solstice to the southern middle altitude of the winter solstice in the main cities of the country assumed to be used. This is because there is a high possibility that it can be used effectively throughout the year in that country. For example, when the country assumed to be used is Japan, the altitude from 31 ° to 79 ° may be included in the second angle range AR2. Furthermore, it is preferable that an altitude of 25 ° to 84 ° is included in the second angle range AR2, since there is a high possibility that it can be used effectively in many countries in the world. In order to make it easier for the desired altitude to be included in the second angle range AR2, it is preferable that the angle range of the second angle range AR2 is continuous by about 45 ° or more. However, it is also possible to make the desired altitude fall within the second angle range AR2 by arranging the solar cell composite display 10 so as to be inclined. On the other hand, the upper limit of the angle range of the second angle range AR2 may be appropriately set in balance with the first angle range AR1, but by setting it to less than about 135 °, the solar cell composite display according to the present embodiment. The features of the body 10 can be exhibited more.

  As described above, the solar cell composite display 10 realizes both display on the display surface 12 and power generation by the solar cell panel 50 using the difference between the observation direction and the incident direction of external light. Therefore, it is required to accurately align the object to be installed. Therefore, the solar cell composite display body 10 of the present embodiment has a frame member 70 in order to hold the sheet member 20 and the solar cell panel 50 in an intended posture. Note that the frame member 70 only needs to support at least the solar cell panel 50, and the sheet member 20 may be directly supported, indirectly supported via the solar cell panel 50, or the sheet member. The sheet member 20 may be supported by another member without supporting the member 20.

  FIG. 9 is a cross-sectional view showing that the frame member 70 holds the sheet member 20 and the solar cell panel 50. As shown in FIG. 9, the frame member 70 extends from the back plate 76 along the normal direction nd of the sheet member 20 to the back plate 76 disposed to face the back surface 50 b of the solar cell panel 50, and And a frame body 71 positioned around the member 20 and the solar cell panel 50.

  The back plate 76 is disposed apart from the back surface 50b of the solar cell panel 50, and the electric device 55 connected to the solar cell panel 50 is disposed in a space between the back plate 76 and the back surface 50b of the solar cell panel 50. Contained. The electric device 55 includes a battery that stores electric energy generated by the solar cell panel 50, a control device that monitors the solar cell panel 50, and the like.

  The frame body 71 faces the side surface 50 c of the solar cell panel 50 and holds the solar cell panel 50. Further, the frame body 71 faces the side surface 20 c of the sheet member 20 and also holds the sheet member 20. The side surface 20c of the sheet member 20 is a surface extending between the first surface 20a and the second surface 20b, and in the illustrated example, a pair of surfaces facing the first axial direction d1 and a second axis And a pair of surfaces opposed to the direction d2.

  Each frame 71 extends from the back plate 76 toward the sheet member 20 along the normal direction nd of the sheet member 20. In other words, the frame body 71 extends toward the sheet member 20 side along the normal direction nd of the sheet member 20 from the region opposite to the sheet member 20 with respect to the solar cell panel 50. And the front end surface 74 which faces the normal line direction nd of the sheet | seat member 20 is formed in this extended front-end | tip.

  Furthermore, the frame body 71 shown in FIG. 9 extends to the sheet member 20 side from the light receiving surface 50a of the solar cell panel 50, and further beyond the first surface 20a of the sheet member 20, the first surface 20a. To the normal direction nd of the sheet member 20. Therefore, the front end surface 74 of the frame 71 is located on the opposite side of the solar cell panel 50 with respect to the first surface 20a of the sheet member 20. Thus, by allowing the frame 71 to protrude beyond the first surface 20a of the sheet member 20, the sheet member 20 and the solar cell panel 50 can be protected from collision with an obstacle.

  However, this protruding portion can be a factor that blocks sunlight L91 incident on the sheet member 20. Therefore, in the present embodiment, at least a part of the region 71a of the frame 71 that extends to the sheet member 20 side from the light receiving surface 50a of the solar cell panel 50 is made light transmissive. According to such a form, it becomes possible to reduce the possibility that the region 71a extending beyond the light receiving surface 50a blocks the light L91 incident on the sheet member 20. In the example shown in FIG. 9, the entire region 71a extending from the light receiving surface 50a is made of a transparent material having light transmittance. Examples of such a material include glass and a transparent resin material.

  In particular, the frame body 71 shown in FIG. 9 includes a first frame 72 and a second frame 73 disposed to face each other in the first axial direction d1. The first frame 72 is located on one side in the first axial direction d1 and faces the side surface 20c of the sheet member 20 and the side surface 50c of the solar cell panel 50 from one side. The second frame 73 is located on the other side in the first axial direction d1 and faces the side surface 20c of the sheet member 20 and the side surface 50c of the solar cell panel 50 from the other side. However, the configuration of the frame 71 is not limited to such an example. In addition to the first frame 72 and the second frame 73, the frame body 71 may further include a pair of frames arranged facing the second axial direction d <b> 2, or the first frame 72 and the second frame 73 Instead, a pair of frames opposed to the second axial direction d2 may be included.

  In the example shown in FIG. 9, a plurality of grooves 81 are formed in the first frame 72 and the second frame 73, and the sheet member 20 and the solar cell panel 50 are fitted in the corresponding grooves 81. By using the groove 81, the sheet member 20 and the solar cell panel 50 can be detachably attached to the frame member 70.

  The frame 71 holds the solar cell panel 50 and the sheet member 20 with a space therebetween, and the air layer 30 is interposed therebetween. Furthermore, since the entire region 71a of the frame 71 that extends to the sheet member 20 side from the light receiving surface 50a of the solar cell panel 50 has light transmittance, naturally, the sheet of the frame 71 A region 71b between the solar cell panel 50 and the sheet member 20 in the normal direction nd of the member 20 also has light transmittance. For this reason, the light L92 which goes to the solar cell panel 50 can also be taken in from the area | region 71b in the meantime.

  As described above, according to the present embodiment, the frame member 70 that holds at least the solar cell panel 50 is further provided. By providing the frame member 70, it contributes to stably installing the solar cell panel 50 on the installation target.

  Further, according to the present embodiment, the solar cell panel 50 includes the light receiving surface 50a facing the second surface 20b of the sheet member 20, the back surface 50b facing the light receiving surface 50a, and the light receiving surface 50a and the back surface 50b. The frame member 70 has a frame body 71 that faces the side surface 50c of the solar cell panel 50 and holds the solar cell panel 50. The frame body 71 is a solar cell panel. 50 extends from the region opposite to the sheet member 20 toward the sheet member 20 along the normal direction nd of the sheet member 20. According to such a form, since the solar cell panel 50 can be hold | maintained by the side surface 50c, the possibility that the light-receiving surface 50a may be blocked by the frame member 70 can be reduced. As a result, it is excellent in that power generation by the solar cell panel 50 can be effectively performed.

  Further, according to the present embodiment, the frame body 71 protrudes closer to the sheet member 20 than the light receiving surface 50 a of the solar cell panel 50. By projecting the frame 71 beyond the light receiving surface 50a, the solar cell panel 50 can be protected from collision with an obstacle. In addition, the frame 71 extends beyond the first surface 20 a from the second surface 20 b side of the sheet member 20, and protrudes from the first surface 20 a in the normal direction nd of the sheet member 20. By projecting the frame 71 beyond the first surface 20a of the sheet member 20, the sheet member 20 can be protected from collision with an obstacle in addition to the solar cell panel 50.

  Moreover, according to this Embodiment, the frame 71 is holding the solar cell panel 50 and the sheet | seat member 20 at intervals. In this case, scratches and wear due to contact between the light receiving surface 50a of the solar cell panel 50 and the second surface 20b of the sheet member 20 can be avoided. In addition, in the frame 71, a region 71b between the solar cell panel 50 and the sheet member 50 in the normal direction nd of the sheet member 20 has light transmittance. For this reason, it is possible to capture a part of the light L92 toward the solar cell panel 50 from the region 71b between the solar cell panel 50 and the sheet member 50 without using the sheet member 20.

  Moreover, according to this Embodiment, at least one part of the area | region 71a extended to the sheet | seat member 20 side rather than the light-receiving surface 50a of the solar cell panel 50 of the frame 71 has a light transmittance. According to such a form, it becomes possible to reduce the possibility that the region 71a extending beyond the light receiving surface 50a blocks the light L91 incident on the sheet member 20.

<< Modification of Frame Member 70 >>
Various modifications can be made to the above-described embodiment. Hereinafter, an example of modification will be described with reference to the drawings. In the following description and the drawings used in the following description, the same reference numerals as those used for the corresponding parts in the above embodiment are used for the parts that can be configured in the same manner as in the above embodiment. A duplicate description is omitted.

  In the embodiment described above, as shown in FIG. 2, an example in which the entire region 71 a of the frame 71 that extends to the sheet member 20 side from the solar cell panel 50 has light transmittance has been shown. The configuration of the frame 71 is not limited to the configuration described above. 10 and 11 show other configuration examples of the frame 71, respectively. In the example shown in FIG. 10, the region 71 a of the frame 71 that extends to the sheet member 20 side from the light receiving surface 50 a of the solar cell panel 50 is reflected on the surface facing the side surface 50 c of the solar cell panel 50. It has a surface 75. In the example shown in FIG. 10, the reflection processing surface 75 provided on the first frame 72 is opposed to the side surface 20 c of the sheet member 20 from one side in the first axial direction d <b> 1 and is provided on the second frame 73. The surface 75 faces the side surface 20c of the sheet member 20 from the other side in the first axial direction d1.

  As an example, the reflection processing surface 75 is formed of a thin film made of a material having a high reflectance, for example, a metal such as aluminum. Moreover, in order to guide the light reflected by the reflection processing surface 75 to a wide range of the light receiving surface 50a of the solar cell panel 50, the reflection processing surface 75 preferably has a light diffusion function. An example of such a reflection-treated surface 75 is a layer made of white ink.

  According to the reflection processing surface 75, the light L101 and L102 which entered into the area | region 71a extended to the sheet member 20 side rather than the light-receiving surface 50a of the solar cell panel 50 of the frame 71 are made into the sheet member 20 or a solar cell panel. 50, the light utilization efficiency can be improved.

  In the example shown in FIG. 10, the sheet member 20 is bonded to the solar cell panel 50 via the low refractive index resin layer 35. The low refractive index resin layer 35 is made of a material having a refractive index lower than that of the material forming the sheet member 20, and an example thereof is a transparent thermoplastic resin.

  On the other hand, in the example shown in FIG. 11, the region 71 b between the solar cell panel 50 and the sheet member 50 in the normal direction nd of the sheet member 20 in the frame body 71 is made of a material that transmits light. On the other hand, the region 71c of the frame 71 that overlaps the side surface 20c of the sheet member 20 is made of a material that does not transmit light. Specifically, the former region 71b is made of glass or a transparent resin material, and the latter region 71c is made of a resin material colored in a wooden frame or black.

  Even in the form shown in FIG. 11, the frame 71 holds the solar cell panel 50 and the sheet member 20 at an interval. In this case, scratches and wear due to contact between the light receiving surface 50a of the solar cell panel 50 and the second surface 20b of the sheet member 20 can be avoided. In addition, in the frame 71, a region 71b between the solar cell panel 50 and the sheet member 50 in the normal direction nd of the sheet member 20 has light transmittance. For this reason, it is possible to capture a part of the light L92 toward the solar cell panel 50 from the region 71b between the solar cell panel 50 and the sheet member 50 without using the sheet member 20.

  In the example shown in FIG. 11, the front end surface 74 of the frame body 71 coincides with the first surface 20 a of the sheet member 20 at a position along the normal direction nd of the sheet member 20. That is, the front end surface 74 of the frame 71 does not form a step with the first surface 20a of the sheet member 20, and is smoothly connected to form a flat surface. According to such a form, after holding the solar cell panel 50 by the frame body 71, the possibility of blocking the light L121 that should be incident on the sheet member 20 by the frame body 71 can be reduced.

  Moreover, in embodiment mentioned above, as shown in FIG. 2, although the frame 71 showed the example extended to the sheet | seat member 20 side rather than the light-receiving surface 50a of the solar cell panel 50, the structure of the frame 71 is shown. The configuration is not limited to that described above. 12 and 13 show other configuration examples of the frame 71, respectively. Among these, in the example shown in FIG. 12, the front end surface 74 of the frame 71 is located at a position between the light receiving surface 50a and the back surface 50b of the solar cell panel 50 in the normal direction nd of the sheet member 20. .

  In the example shown in FIG. 12, the frame body 71 holds the side surface 50 c of the solar cell panel 50. Further, the sheet member 20 is joined to the solar cell panel 50 via the low refractive index resin layer 35. The low refractive index resin layer 35 is made of a material having a refractive index lower than that of the material forming the sheet member 20, and an example thereof is a transparent thermoplastic resin.

  According to the form shown in FIG. 12, after the solar battery panel 50 is held by the frame body 71, the risk of blocking the light L <b> 121 that should be incident on the sheet member 20 by the frame body 71 can be reduced. In addition, a part of the light L122 toward the solar cell panel 50 can be taken from the low refractive index resin layer 35 between the solar cell panel 50 and the sheet member 50 without passing through the sheet member 20.

  On the other hand, in the example shown in FIG. 13, the position of the front end surface 74 of the frame body 71 along the normal direction nd of the sheet member 20 with the light receiving surface 50 a of the solar cell panel 50 coincides. That is, the front end surface 74 of the frame 71 is smoothly connected to the light receiving surface 50a of the solar cell panel 50 to form a flat surface, and no step is formed between the light receiving surface 50a. According to such a form, after holding the solar cell panel 50 by the frame 71, the possibility of blocking the light L131 that should be incident on the sheet member 20 by the frame 71 can be reduced. In addition, a part of the light L <b> 132 toward the solar cell panel 50 can be taken from the low refractive index resin layer 35 between the solar cell panel 50 and the sheet member 50 without passing through the sheet member 20.

  In the example shown in FIG. 13, the sheet member 20 covers the front end surface 74 of the frame 71. In this case, since the front end surface 74 of the frame 71 can be hidden by the sheet member 20 on which the plurality of display surfaces 12 are arranged, the appearance can be improved.

  In the above-described embodiment, as shown in FIG. 9, the example in which the sheet member 20 and the solar cell panel 50 are held by the frame body 71 to be parallel to each other is shown. Is not limited to the configuration described above. 14 and 15 show other configuration examples of the frame 71, respectively. Among these, in the example shown in FIG. 14, the frame 71 holds the sheet member 20 so as to be removable, and holds the solar cell panel 50 so that the orientation can be adjusted.

  A plurality of grooves 81 are formed in the first frame 72 and the second frame 73 constituting the frame body 71. The plurality of grooves 81 formed in each of the frames 72 and 73 are arranged along the normal direction nd of the sheet member 20. Each groove 81 is processed according to the shape of the solar cell panel 50 in the direction so as to hold the solar cell panel 50 in the intended direction.

  According to such a configuration, the relative inclination between the solar cell panel 50 and the sheet member 20 can be changed by appropriately selecting the groove 81 of the first frame 72 and the groove 81 of the second frame 73. . Specifically, as shown by a two-dot chain line in FIG. 14, a groove 81 farthest from the back plate 76 of the first frame 72 and a groove 81 farthest from the back plate 76 of the second frame 73 are selected. Thus, the solar cell panel 50 and the sheet member 20 can be held in parallel. Further, as shown by a solid line in FIG. 14, by selecting the groove 81 closest to the back plate 76 of the first frame 72 and the groove 81 at the center of the second frame 73, the main cut surface shown in FIG. 14 is obtained.

Each adjustment support 82 changes its own length, so that the distance between the solar cell panel 50 and the back plate 76 can be adjusted. However, adjustment of the space | interval between the solar cell panel 50 and the backplate 76 is not limited to such an example. As another example, by preparing a plurality of adjustment supports 82 having different lengths and selecting the adjustment support 82 having a desired length according to the purpose, the space between the solar cell panel 50 and the back plate 76 is selected. The interval may be adjusted.

  14 and 15, the solar cell panel 50 is supported by the frame member 70 so that the relative inclination between the solar cell panel 50 and the sheet member 20 can be changed. In this case, it is possible to efficiently capture sunlight by adjusting the inclination of the solar cell panel 50 in accordance with the direction in which the solar cell composite display 10 faces.

  Moreover, in embodiment mentioned above, as shown in FIG. 2, although the frame member 70 showed the example comprised by the frame 71 located around the sheet member 20 and the solar cell panel 50, the frame member 70 was shown.

It becomes easy to effectively use light incident from the direction. In particular, the light transmission surface 22 is inclined with respect to the panel surface of the solar cell panel 50 at an angle different from that of the orientation adjustment surface 21. For this reason, the display surface 12 disposed on the orientation adjustment surface 21 is visually recognized when the solar cell composite display body 10 is observed from a direction D211 different from the direction in which the light L212 that is easily taken into the light transmission surface 22 is inclined. The light transmission surface 22 effectively captures the light L212 incident on the solar cell composite display body 10 from a direction different from the direction D211 in which the direction adjustment surface 21 is easily visible. As a result, it is possible to effectively achieve both the display on the display surface 12 and the power generation by the solar cell panel 50.

In addition, since the solar cell panel 50 is disposed to face the second surface 20b of the sheet member 20, the light receiving surface 50a of the solar cell panel 50 is not exposed to the outside. For this reason, the solar cell panel 50 can be made more inconspicuous.

  According to the present embodiment, the first surface 20a of the sheet member 20 includes a plurality of lens surfaces 31 arranged along the uniaxial direction d1, and each display surface 12 has a corresponding lens surface 31.

Is effectively possible. In addition, since the solar cell panel 50 is disposed to face the second surface 20b of the sheet member 20, the light receiving surface 50a of the solar cell panel 50 is not exposed to the outside. For this reason, the solar cell panel 50 can be made more inconspicuous.

  Further, according to the present embodiment, the plurality of display surfaces 12 are disposed inside the sheet member 20. In this case, it is advantageous in that the display surface 12 can be protected by the material forming the sheet member 20.

  Next, still another modification of the solar cell composite display 10 will be described with reference to FIG. In the example illustrated in FIG. 27, the solar cell composite display 10 includes a sheet-like sheet member 20 and a solar cell panel 50 disposed to face the second surface 20 b of the sheet member 20.

  The first surface 20a of the sheet member 20 includes a plurality of lens surfaces 31 arranged in the first axial direction d1. The plurality of lens surfaces 31 are arranged such that their optical axes od are parallel to each other. In particular, in the illustrated example, the lens surface 31 is arranged so that the optical axis od thereof is parallel to the normal direction nd of the solar cell composite display body 10.

  The lens surface 31 constitutes a so-called lenticular lens or cylindrical lens. In other words, each lens surface 31 extends linearly in a direction intersecting the first axis direction d1 that is the arrangement direction, more specifically in a second direction d2 orthogonal to the first axis direction d1.

  A plurality of display surfaces 12 are arranged in the sheet member 20 along the first axial direction d <b> 1 corresponding to the lens surface 31. As shown in FIG. 27, each display surface 12 is arranged so as to face at least partly the corresponding lens surface 31 along the normal direction nd. In the present embodiment, similarly to the lens surface 31, the display surface 12 is in a direction intersecting the first axis direction d1 that is the arrangement direction, more strictly, in a second direction d2 orthogonal to the first axis direction d1. It extends in a straight line. Each display surface 12 is inclined with respect to the panel surface of the solar cell panel 50 and the normal direction nd of the sheet member 20.

  Next, the effect | action of the solar cell composite display body 10 by this Embodiment is demonstrated.

  As well shown in FIG. 27, the inclined display surface 12 is easily visible from the front direction of the display surface 12. In the present embodiment, the display surface 12 is inclined to one side in the first axial direction d1 with respect to the normal direction nd of the sheet member 20, and thus in the first axial direction d1 with respect to the normal direction nd. When the solar cell composite display body 10 is observed from the directions D271 and D272 inclined to the other side, the display surface 12 is easily visually recognized. In particular, even when the solar cell composite display 10 is observed from a direction D272 that is greatly inclined to the other side in the first axial direction d1 with respect to the normal direction nd, Thus, the display surface 12 facing the lens surface 31 can be observed. If a plurality of display surfaces 12 are arranged on the second surface 20b of the sheet member 20 along the second surface 20b, the display surface 12 is adjacent to the lens surface 31 to be observed as shown by a dotted line in FIG. The display surface 12 facing the lens surface 31 is observed, and the intended display function may not be exhibited. That is, by tilting the display surface 12 with respect to the panel surface of the solar battery panel 50, the first angle range AR1 serving as a viewing angle at which the display surface 12 is observed, in other words, emission of light from the display surface 12 is displayed. The first angle range AR1 that is the angle range of the direction can be adjusted with a high degree of freedom.

  On the other hand, the light flux L273 traveling in the sheet member 20 from the direction in which the angle formed with respect to the display surface 12 is smaller is less likely to be received by the display surface 12. From this, the light beam L273 toward the solar cell panel 50 without being blocked by the inclined display surface 12 is inclined to the opposite side to the directions D271 and D272 in which the display surface 12 can be effectively observed, as shown in FIG. Light flux L273. That is, light that enters the lens surface 31 while traveling to the other side in the first axial direction d1, in the illustrated example, a light beam L273 that travels downward in the vertical direction and enters the lens surface 31 is between the two display surfaces 12. It becomes easy to be guided to the solar cell panel 50 through the region 60.

  As described above, according to the embodiment shown in FIG. 27, the sheet member 20 having the first surface 20a and the second surface 20b facing the first surface 20a, and the second surface 20b of the sheet member 20 are disposed opposite to each other. The sheet member 20 includes a plurality of display surfaces 12 that are inclined with respect to the panel surface of the solar cell panel 50 and arranged along the uniaxial direction d1. According to such a solar cell composite-type display body 10, since the display surface 12 is inclined with respect to the panel surface of the solar cell panel 50, the inclined display surface 12 is from the directions D271 and D272 that become the front direction. It becomes easy to observe. On the other hand, the light beam L273 incident on the solar cell composite display body 10 from another direction different from the directions D271 and D272 in which the display surface 12 can be easily seen is transmitted between the two adjacent display surfaces 12 and is solar cell panel. To 50. As described above, the difference between the observation directions D271 and D272 from the observer and the incident direction of the external light L273 is utilized to achieve harmony with the surrounding environment, and display on the display surface 12 and power generation by the solar cell panel 50. Can be effectively achieved. In addition, since the solar cell panel 50 is disposed to face the second surface 20b of the sheet member 20, the light receiving surface 50a of the solar cell panel 50 is not exposed to the outside. For this reason, the solar cell panel 50 can be made more inconspicuous.

  Further, according to the present embodiment, the plurality of display surfaces 12 are disposed inside the sheet member 20. In this case, it is advantageous in that the display surface 12 can be protected by the material forming the sheet member 20.

  The first surface 20a of the sheet member 20 includes a plurality of lens surfaces 31 arranged in a uniaxial direction d1, and the lens surface 31 guides light coming from a certain direction D271, D272 to the display surface 12, Light L273 incident from a different direction different from the certain directions D271 and D272 is transmitted between the two adjacent display surfaces 12 and guided to the solar cell panel 50. According to such a configuration, the first angle range AR1 that is the viewing angle at which the display surface 12 is observed and the second angle range AR2 in which power generation by the solar cell panel 50 is effectively performed by the light collecting action of the lens surface 31. Can be adjusted with a high degree of freedom.

  Note that the sheet member 20 shown in FIGS. 21 to 27 can be used in combination with the frame member 70 described with reference to FIGS. 9 to 20. That is, the solar cell composite display 10 shown in FIGS. 21 to 27 can further include the above-described frame member 70 that holds at least the solar cell panel 50. By providing the frame member 70, it contributes to stably installing the solar cell panel 50 on the installation target.

  Further, according to the solar cell composite display 10 shown in FIGS. 21 to 27, the solar cell panel 50 includes a light receiving surface 50a facing the second surface 20b of the sheet member 20 and a back surface 50b facing the light receiving surface 50a. And a side surface 50c extending between the light receiving surface 50a and the back surface 50b. The frame member 70 has a frame body 71 that faces the side surface 50c of the solar cell panel 50 and holds the solar cell panel 50. Then, the frame body 71 may extend toward the sheet member 20 side along the normal direction nd of the sheet member 20 from a region opposite to the sheet member 20 with respect to the solar cell panel 50. According to such a form, since the solar cell panel 50 can be hold | maintained by the side surface 50c, the possibility that the light-receiving surface 50a may be blocked by the frame member 70 can be reduced. As a result, it is excellent in that power generation by the solar cell panel 50 can be effectively performed.
