Description

  The present invention relates to a display object capable of exhibiting a predetermined display function while ensuring sufficient translucency.

  Utilizing the difference between the incident direction of the external light and the observation direction from the observer, the line of sight from another angular direction different from the certain angular direction is blocked while transmitting the incident light from the certain angular direction. There are known lighting and blocking devices that can be used. Examples of such daylighting and blocking devices include blinds and blindfold louvers. The daylighting and shielding apparatus usually includes a plurality of plate-like bodies arranged in a uniaxial direction, and each plate-like body is inclined with respect to the uniaxial direction.

  By the way, if there is a display that can exhibit a predetermined display function while ensuring sufficient translucency, for example, it can be used as an advertising signboard installed on a panel surface facing the outside of a window glass of a building. Is extremely useful. However, such display objects are not known.

  The present inventor can exhibit a predetermined display function while ensuring sufficient translucency by printing a predetermined display object on the plurality of plate-like bodies of the daylighting and shielding apparatus described above. I thought it was possible. Specifically, for example, the display target element is printed in a visible region that can be observed from a certain angle direction in each plate-like body, so that the observer can ensure the sufficient translucency. When observing the apparatus from the angular direction, it is possible to observe a good display object by a combination of display object elements.

  However, when the observer observes the apparatus from another angle direction different from the certain angle direction, the adjacent display target elements are separated from each other, so that an extra blank area is inserted in the display target or adjacent to the display target element. There is a problem that a part of the display target is lost due to the overlapping display target elements. That is, this apparatus has a problem that the angle range in which the observer can observe a good display target is extremely narrow.

  The present invention has been made in consideration of the above points, and a display capable of widening an angle range in which an observer can observe a good display object while ensuring sufficient translucency. The purpose is to provide goods.

  FIG. 1 is a perspective view showing a display object 10 according to an embodiment of the present invention. FIG. 2 is a cross-sectional view taken along line AA of the display object 10 of FIG.

  The display object 10 of the present embodiment can be used for various purposes, for example, for large panels of several meters to several tens of meters used for outdoor signs, road information bulletin boards, outer wall surfaces of buildings, Examples of the medium-sized panel use of several tens of cm to several m used for posters, signs, inner wall surfaces of buildings, and the like can be given.

  As shown in FIGS. 1 and 2, the display object 10 includes a plurality (five in the illustrated example) of plate-like bodies 12a to 12e arranged in the first axial direction d1. In the illustrated example, the display object 10 is disposed on the panel surface 11s facing the outside of the window glass 11 of the building. The first axial direction d1 is parallel to the panel surface 11s and is orthogonal to the normal direction nd of the panel surface 11s. In the illustrated example, the first axis direction d1 is parallel to the vertical direction, and the normal direction nd of the panel surface 11s is parallel to the horizontal direction.

  Each of the plate-like bodies 12a to 12e is made of, for example, wood or resin. When the direction in which each plate-like body 12a to 12e extends on the main cutting plane (paper surface in FIG. 2) parallel to both the first axial direction d1 and the normal direction nd of the panel surface 11s is referred to as a second axial direction d2. The length of each plate-like body 12a to 12e in the second axial direction d2 is, for example, 1 cm or more, and more specifically, for example, about 30 cm to 50 cm. The arrangement pitch of the plate-like bodies 12a to 12e in the first direction d1, that is, the center interval between the adjacent plate-like bodies 12a to 12e is, for example, 10 cm or more, and more specifically, for example, about 30 cm to 50 cm. . In the illustrated example, the plate-like bodies 12a to 12e are configured identically.

  Each plate-like body 12a-12e has the 1st surface 21 and the 2nd surface 22 as a pair of main surface which mutually opposes. Among these, the first surface 21 is provided with a display surface 24 for performing display. Examples of display objects displayed on the display surface 24 include graphics (patterns) such as graphics, patterns, designs, colors, pictures, photographs, and characters, and information such as letters, marks, and numbers.

  As shown in FIGS. 1 and 2, the display surface 24 is inclined with respect to the first axial direction d <b> 1, and in the illustrated example, is inclined with respect to the panel surface 11 s of the window glass 11.

  More specifically, as shown in FIG. 2, the display surface 24 has one end portion located on one side in the first axial direction d1 (in the illustrated example, the upper side in FIG. 2 and the upper side in the vertical direction). The window in the normal direction nd of the panel surface 11s rather than the other end located on the other side in the first axial direction d1 (the lower side in FIG. 2 and the lower side in the vertical direction in the illustrated example) It inclines with respect to the panel surface 11s so that it may space apart from the glass 11. FIG. As can be understood from FIG. 2, according to the plate-like bodies 12a to 12e having such a display surface 24, a direction inclined to the other side (downward) with respect to the normal direction nd of the panel surface 11s, that is, Light is easily emitted from the display surface 24 toward the angle directions D21 to D24 in the second angle range AR2. Therefore, the display function from the display surface 24 can be effectively exhibited when observed from the directions D21 to D24 in the angle range AR2 inclined to the other side with respect to the normal direction nd. On the other hand, light incident on the display object 10 from the direction inclined to one side (upper side) with respect to the normal direction nd of the panel surface 11s, that is, the angular direction D11 within the first angular range AR1, is plate-like bodies 12a to 12e. Is less likely to be blocked by, and easily passes through the space between the adjacent plate-like bodies 12a to 12e to the panel surface 11s.

  From the viewpoint of enhancing such a tendency, the display surface 24 is in the first axial direction d1 on the main cutting plane (paper surface in FIG. 2) parallel to both the first axial direction d1 and the normal direction nd of the panel surface 11s. It is preferable to approach the panel surface 11s in the normal direction nd of the panel surface 11s stepwise or continuously from one side (upper side) to the other side (lower side). In the illustrated example, on the main cutting plane (paper surface in FIG. 2) parallel to both the first axis direction d1 and the normal direction nd of the panel surface 11s, the display surface 24 is one side in the first axis direction d1 ( From the upper side to the other side (lower side), the panel surface 11s approaches the panel surface 11s in the normal direction nd of the panel surface 11s with a constant inclination. According to the plate-like bodies 12a to 12e having such a display surface 24, a direction inclined to the other side (lower side) with respect to the normal direction nd of the panel surface 11s, that is, an angular direction within the second angular range AR2. Light is easily emitted from the display surface 24 toward D21 to D24. Therefore, the display function from the display surface 24 can be effectively exhibited when observed from the directions D21 to D24 in the angle range AR2 inclined to the other side with respect to the normal direction nd. On the other hand, the light incident on the display object 10 from the angle direction D11 within the first angle range AR1 is not easily blocked by the plate bodies 12a to 12e, and passes through the space between the adjacent plate bodies 12a to 12e. It becomes easy to guide to the surface 11s.

  In the present embodiment, the display surface 24 is inclined with respect to the first axial direction d1, but the present invention is not limited to this, and the display surface 24 is perpendicular to the first axial direction d1. Also good.

  As shown in FIG. 1, each plate-like body 12a-12e is extended linearly in the direction which cross | intersects with respect to the 1st axial direction d1 which is the arrangement direction. In particular, in the illustrated example, each of the plate-like bodies 12a to 12e extends linearly in a third axial direction d3 orthogonal to both the first axial direction d1 and the normal direction nd of the panel surface 11s. Thereby, the display function from the display surface 24 can be exhibited continuously over the third axial direction d3.

  Further, as shown in FIG. 2, the plurality of plate-like bodies 12 a to 12 e are partly adjacent to each other when the display object 10 is observed from the directions D21 to D24 in the second angle range AR2. Are arranged in the first axial direction d1 so as to overlap each other. In the present specification, “partially overlap” means that at least a part overlaps, the whole overlaps, and the end edges overlap (that is, the end edges touch each other). Means a concept that also includes With such an arrangement, the display function from the display surface 24 can be continuously exhibited over the first axial direction d1.

  Next, the structure of the display surface 24 of each plate-like body 12a to 12e will be described in detail.

  As shown in FIG. 4, each unit display surface 40 is positioned so as to individually correspond to a different unit lens 50. Each unit lens 50 expresses a lens function with respect to light emitted from the corresponding unit display surface 40, and adjusts the traveling direction of the light. That is, as shown in FIG. 4, the unit lens 50 refracts the light from the first display portion 41 of the corresponding unit display surface 40 and emits it in the first angle direction D <b> 21, and from the second display portion 42.

That is, the unit lenses 50 extend linearly in a direction intersecting the second axis direction d2 that is the arrangement direction. In particular, in the illustrated example, the unit lens 50 extends linearly in the third axial direction d3. Further, the plurality of unit lenses 50 included in the lens unit 28 are configured identically to each other. As an example, the lens part 28 is produced by molding a transparent resin. As the molding method, hot melt extrusion, injection molding, or the like can be employed.

In the illustrated example, the optical axis of the second lens surface 51b is positioned so as to be shifted to the window glass 11 side (right side in FIG. 4) with respect to the optical axis of the first lens surface 51a.

  Each unit display surface 40 is individually provided on the corresponding second lens surface 51b. The unit display surface 40 has a concave shape corresponding to the convex lens shape of the second lens surface 51b. As an example, the unit display surface 40 is formed by coating on the second lens surface 51b by ink jet printing. In the illustrated example, the first display portion 41, the second display portion 42, the third display portion 43, and the fourth display portion 44 are in a direction away from the window glass 11 (a direction from the right side to the left side in FIG. 4). They are provided in this order. As a result, as shown in FIG. 4, the light from the first display portion 41 is refracted by the unit lens 50 and is relatively raised with respect to the panel surface 11 s of the window glass 11 in the first angle direction D21 (for example, the panel Light emitted from the second display portion 42 is refracted by the unit lens 50 and slightly slept with respect to the panel surface 11s of the window glass 11. The light is emitted in a direction D22 (for example, a direction inclined by 60 ° with respect to the panel surface 11s), and the light from the third display portion 43 is refracted by the unit lens 50 and more laid on the panel surface 11s of the window glass 11. The light is emitted in the third angle direction D23 (for example, the direction inclined by 30 ° with respect to the panel surface 11s), and the light from the fourth display portion 44 is refracted by the unit lens 50 and the panel surface of the window glass 11 The light is emitted in a fourth angle direction D24 (for example, a direction substantially parallel to the panel surface 11s) which is considerably lying with respect to 11s.

  By the way, as can be understood from FIG. 2, the overlapping amount in the second axis direction d2 of the adjacent plate-like bodies 12a to 12e changes according to the angular directions D21 to D24 for observing the display object 10, and as a result, Of the display surface 24 of each plate-like body 12a to 12e, the size of the observable visible region 70 changes.

Therefore, when observing the display object 10 from the first angle direction D21 within the second angle range AR2, the observer observes the first display target 31 that is favorable by the combination of the first display target elements 31a to 31e. The adjacent first display target elements 31a to 31e are separated from each other and an extra blank area is inserted into the first display target 31, or the adjacent first display target elements 31a to 31e are partially connected to each other. Heavy Matching a portion of the first display object 31 is lost, the problem can be prevented.

  The unit lenses 50 provided on the display surface 24 refract the light from the second display portion 42 in the corresponding unit display surfaces 40 and emit the light in the second angle direction D22. 2nd display object element 32a-32e is provided with respect to the 2nd visible region 72 which can be observed from 2nd angle direction D22 within 2nd angle range AR2 among the display surfaces 24 of plate-shaped body 12a-12e. Thus, when observing the display object 10 from the second angle direction D22 within the second angle range AR2, the observer may observe the good second display object 32 by combining the second display object elements 32a to 32e. The adjacent second display target elements 32a to 32e are separated from each other and an extra blank area is inserted in the second display target 32, or the adjacent second display target elements 32a to 32e partially overlap each other. A portion of the second display object 32 is lost, a problem can be prevented.

  The unit lenses 50 provided on the display surface 24 refract light from the third display portion 43 of the corresponding unit display surfaces 40 and emit the light in the third angle direction D23. The third display target elements 33a to 33e are provided to the third visible region 73 that can be observed from the third angle direction D23 within the second angle range AR2 in the display surfaces 24 of the plate-like bodies 12a to 12e. Thus, when observing the display object 10 from the third angle direction D23 within the second angle range AR2, the observer may observe the good third display target 33 by combining the third display target elements 33a to 33e. The adjacent third display target elements 33a to 33e are separated from each other and an extra blank area is inserted into the third display target 33, or the adjacent third display target elements 33a to 33e partially overlap each other. Part of the third display object 33 is lost, a problem can be prevented.

  Each unit lens 50 provided on the display surface 24 refracts light from the fourth display portion 44 of the corresponding unit display surface 40 and emits it in the fourth angle direction D24. 4th display object element 34a-34e is provided with respect to the 4th visible region 74 which can be observed from the 4th angle direction D24 in 2nd angle range AR2 among the display surfaces 24 of plate-shaped body 12a-12e. Thus, when observing the display object 10 from the fourth angle direction D24 within the second angle range AR2, the observer may observe the favorable fourth display object 34 by combining the fourth display object elements 34a to 34e. The adjacent fourth display target elements 34a to 34e are separated from each other and an extra blank area is inserted in the fourth display target 34, or the adjacent fourth display target elements 34a to 34e partially overlap each other. Part of the fourth display object 34 is lost, a problem can be prevented.

  Therefore, the observer can observe the good display objects 31 to 34 from the four directions of the first to fourth angle directions D21 to D24, that is, the angle at which the good display objects 31 to 34 can be observed. The range can be widened four times compared to the case where the display object is simply printed on the plate-like bodies 12a to 12e.

  In this Embodiment, as shown in FIG. 2, the reflective surface 25 is provided in the 2nd surface 22 of each plate-shaped body 12a-12e. As an example, the reflecting surface 25 is formed of a thin film made of a material having a high reflectance. The reflection surface 25 reflects light incident from the angular direction within the first angle range AR1 toward the second surface 22 and guides it to the panel surface 11s. Therefore, by providing the reflecting surface 25 on the second surface 22, the first angle range AR1 corresponding to the incident angle range of the light guided to the panel surface 11s can be widened.

  Next, the operation of the display object 10 as described above will be described.

  The display object 10 according to the present embodiment is arranged such that a first axial direction d1 that is an arrangement direction of the plurality of plate-like bodies 12a to 12e is parallel to the vertical direction. More specifically, the plate-like bodies 12a to 12e are inclined to one side (upper side) in the first axial direction d1 with respect to the normal direction nd of the panel surface 11s, that is, the plate-like bodies 12a to 12e. One end portion located on one side in the first axial direction d1 is located on the upper side in the vertical direction, and the other end portion located on the other side in the first axial direction d1 of each plate-like body 12a to 12e is in the vertical direction. The display object 10 is arranged so as to be located on the lower side of the screen.

  Since the display surfaces 24 of the respective plate-like bodies 12a to 12e are inclined to one side (upper side) in the first axial direction d1 with respect to the normal direction nd of the panel surface 11s, the display surfaces 24 with respect to the normal direction nd. Light tends to be emitted from the display surface 24 in a direction inclined to the other side (lower side) in the first axial direction d1, that is, in the angular directions D21 to D24 in the second angular range AR2. Therefore, the display function from the display surface 24 can be effectively exhibited when observed from the directions D21 to D22 in the angle range AR2 inclined to the other side with respect to the normal direction nd.

  In particular, the plurality of unit lenses 50 provided on the display surface 24 refracts the light from the first display portion 41 of the corresponding unit display surface 40 and emits it in the first angle direction D21. And the 1st visible region 71 which can be observed from the 1st angle direction D21 of each plate-like object 12a-12e displays the 1st display object elements 31a-31e toward the 1st angle direction D21, respectively. Therefore, when observing the display object 10 from the first angle direction D <b> 21, the observer can observe the good first display target 31 by combining the first display target elements 31 a to 31 e.

  Further, the plurality of unit lenses 50 provided on the display surface 24 refracts the light from the second display portion 42 of the corresponding unit display surfaces 40 and emits the light in the second angle direction D22. And the 2nd visible region 72 which can be observed from the 2nd angle direction D22 of each plate-like body 12a-12e displays the 2nd display object elements 32a-32e toward the 2nd angle direction D22, respectively. Therefore, when observing the display object 10 from the second angle direction D <b> 22, the observer can observe the favorable second display object 32 by combining the second display object elements 32 a to 32 e.

  Further, the plurality of unit lenses 50 provided on the display surface 24 refracts the light from the third display portion 43 of the corresponding unit display surface 40 and emits it in the third angle direction D23. And the 3rd visible region 73 which can be observed from the 3rd angle direction D23 of each plate-shaped body 12a-12e displays the 3rd display object elements 33a-33e toward the 3rd angle direction D23, respectively. Therefore, when observing the display object 10 from the third angle direction D <b> 23, the observer can observe the good third display target 33 by a combination of the third display target elements 33 a to 33 e.

  Further, the plurality of unit lenses 50 provided on the display surface 24 refracts the light from the fourth display portion 44 of the corresponding unit display surface 40 and emits it in the fourth angle direction D24. And the 4th visible region 74 which can be observed from the 4th angle direction D24 of each plate-shaped object 12a-12e displays the 4th display object elements 34a-34e toward the 4th angle direction D24, respectively. Therefore, when observing the display object 10 from the fourth angle direction D <b> 24, the observer can observe the favorable fourth display object 34 by a combination of the fourth display object elements 34 a to 34 e.

  On the other hand, the display surfaces 24 of the respective plate-like bodies 12a to 12e are inclined to one side (upper side) in the first axial direction d1 with respect to the normal direction nd of the panel surface 11s. In contrast, light incident on the display object 10 from the direction inclined to one side (upper side) in the first axial direction d1, that is, the angle direction D11 within the first angle range AR1, is transmitted between the adjacent plate-like bodies 12a to 12e. It can be taken into space. The light taken into the space between the adjacent plate bodies 12a to 12e travels through the space between the adjacent plate bodies 12a to 12e and is guided to the panel surface 11s. Thus, the incident angle of the light guided to the panel surface 11s by inclining each plate 12a to 12e to one side (upper side) in the first axial direction d1 with respect to the normal direction nd of the panel surface 11s. The first angle range AR1 corresponding to the range can be adjusted with a high degree of freedom. Therefore, the display object 10 according to the present embodiment can efficiently transmit sunlight in which the incident direction changes according to the time zone and season.

  As described above, according to the present embodiment, the plurality of plate-like bodies 12a to 12e are arranged in the first axial direction d1, and the display surface 24 of each plate-like body 12a to 12e is in the first axial direction. It is inclined with respect to d1 or perpendicular to the first axial direction d1. And the display surface 24 of each plate-shaped body 12a-12e is the several unit lens 50 arranged in the 2nd axial direction d2, and the several unit display surface 40 located facing the several unit lens 50. FIG. Each unit display surface 40 includes first to fourth display portions 41 to 44 arranged in the second axial direction d2, and the unit lens 50 includes first to fourth display portions 41 to 41. The light from 44 is refracted and emitted in different first to fourth angular directions D21 to D24, respectively.

  And the 1st display object elements 31a-31e are provided to the 1st visible region 71 which can be observed from the 1st angle direction D21 among display surfaces 24, and the 1st display object 31 is combined with the 1st display object elements 31a-31e. Is to be formed. In addition, second display target elements 32a to 32e are given to the second visible region 72 that can be observed from the second angle direction D22 in the display surface 24, and the second display target 32 is obtained by combining the second display target elements 32a to 32e. Is to be formed. In addition, the third display target elements 33a to 33e are given to the third visible region 73 that can be observed from the third angle direction D23 in the display surface 24, and the third display target 33 is combined with the third display target elements 33a to 33e. Is to be formed. Further, fourth display target elements 34a to 34e are given to the fourth visible region 74 that can be observed from the fourth angle direction D24 in the display surface 24, and the fourth display target 34 is combined with the fourth display target elements 34a to 34e. Is to be formed.

For this reason, when observing the display object 10 from the first angle direction D21, the observer can observe the favorable first display object 31 by the combination of the first display object elements 31a to 31e. Further, when observing the display object 10 from the second angle direction D22, the observer can observe a good second display object 32 by a combination of the second display object elements 32a to 32e. Further, when observing the display object 10 from the third angle direction D23, the observer can observe the good third display object 33 by combining the third display object elements 33a to 33e. Further, when observing the display object 10 from the fourth angle direction D24, the observer can observe a good fourth display object 34 by combining the fourth display object elements 34a to 34e. Accordingly, when the observer observes the display object 10 from the four directions of the first to fourth angular directions D21 to D24, adjacent display target elements are separated from each other and an extra blank area is inserted in the display target. The display target elements 31a to 31e, 32a to 32e, 33a to 33e, or 34a to 34e are better combined without causing the display target elements to partially overlap each other and part of the display target to be lost. Display objects 31 to 34 can be observed. Therefore, according to the present embodiment, the angle range in which the observer can observe the good display objects 31 to 34 is 4 as compared with the case where the display objects are simply printed on the plate bodies 12a to 12e. The angle can be doubled.

  Further, according to the present embodiment, the plurality of plate-like bodies 12a to 12e are arranged in the first axial direction d1, and the display surface 24 of each of the plate-like bodies 12a to 12e is in the first axial direction d1. The light incident on the display object 10 from the angular direction D11 within the first angular range AR1 is blocked by the respective plate-like bodies 12a to 12e. Instead, the light passes through the space between the adjacent plate-like bodies 12 a to 12 e and is guided to the panel surface 11 s of the window glass 11. Therefore, sufficient translucency can be ensured for the light incident on the display object 10 from the angular direction D11 within the first angle range AR1.

  In particular, in the display object 10 according to the present embodiment, the first angle range AR1, which is the incident angle range of light transmitted through the display object 10, is set in a direction inclined upward in the vertical direction, and the display surface 24 is observed. A second angle range AR2 that is a possible viewing angle is set in a direction inclined downward in the vertical direction. In this case, it is effective when the display object 10 is installed at a position higher than the line of sight in an application as a billboard-installed advertising signboard assumed as a typical use. The observer can observe the display objects 31 to 34 given to the display surface 24 from the angle directions D21 to D24 in the second angle range AR2 in order to observe the display object 10 while looking up to the upper side in the vertical direction. . On the other hand, although the incident direction of sunlight changes depending on the time zone and season, it is incident on the display object 10 while proceeding in a direction inclined downward in the vertical direction or in a substantially horizontal direction. For this reason, even if an incident direction changes according to a time zone or a season, sunlight passes through the space between the plate-like bodies 12a-12e adjacent from the angle direction D11 in 1st angle range AR1, and is a window. It can go to the panel surface 11s of the glass 11.

  Moreover, according to this Embodiment, since the reflective surface 25 is provided in the 2nd surface 22 of each plate-shaped body 12a-12e, it is on the 2nd surface 22 from the angle direction in 1st angle range AR1. The incident light can be reflected and guided to the panel surface 11 s of the window glass 11. Thereby, the first angle range AR1 corresponding to the incident angle range of the light guided to the panel surface 11s can be widened.

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 first angle range AR1. 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 first angle range AR1. Furthermore, it is preferable that an altitude of 49 ° to 61 ° is included in the first angle range AR1, since there is a high possibility that it can be used effectively in many countries in the world. Further, it is more preferable that the first angular range AR1 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 where use is assumed. 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 first angle range AR1. Furthermore, it is preferable that an altitude of 25 ° to 84 ° is included in the first angle range AR1, since it is highly likely that the altitude can be effectively used in many countries in the world. In order to make it easy for the desired altitude to be included in the first angle range AR1, it is preferable that the angle range of the first angle range AR1 is continuous by about 45 ° or more. However, it is also possible to make the desired altitude included in the first angle range AR1 by arranging the display object 10 at an angle. On the other hand, the upper limit of the angle range of the first angle range AR1 may be set as appropriate in balance with the second angle range AR2, but by setting it to less than about 135 °, the display object 10 of the present embodiment is characterized. Can be exhibited more.

  In the present embodiment, each unit display surface 40 has four display portions 41 to 44 arranged in the second axial direction d2, and the light from each display portion 41 to 44 is unit lens 50. However, the present invention is not limited to this, and the unit display surfaces 40 are arranged in the second axial direction d2. Two or three display portions may be provided, and light from each display portion may be refracted by the unit lens 50 to be emitted in two or three different angular directions. Alternatively, each unit display surface 40 has five or more display parts arranged in the second axial direction d2, and light from each display part is refracted by the unit lens 50, so that they are different from each other. The light may be emitted in more than one angular direction. As the number of display portions included in one unit display surface 40 is increased, the angle range in which the observer can observe a good display target can be further widened. However, as the number of display portions included in one unit display surface 40 is increased, the display by each display portion becomes unclear, so the maximum number of display portions included in one unit display surface 40 is practically Is considered to be about four.

  Moreover, in this Embodiment, although the display object 10 was arrange | positioned on the panel surface 11s of the window glass 11 of a building, it is not limited to this. For example, the display object 10 may be arrange | positioned on the panel surface of the solar cell panel of wall surface installation.
