Alternatively, the entire back surface portion 13 of the display module 9 may be connected to the positioning member 11, and the positioning member 11 may be supported by the unit substrate 10. In this case, the plurality of display modules 9 are supported by the unit substrate 10 via the positioning member 11.
The unit substrate 10 is made of a metal such as aluminum. In addition, the material of the unit substrate 10 is not limited, and any material may be used.
The unit substrate 10 corresponds to an embodiment of a support member that supports one or more display modules according to the present technology.

The positioning member 11 is arranged between the back surface portion 13 of the display module 9 and the unit substrate 10.
The positioning member 11 is a member that defines the position of each of the plurality of display modules 9 with respect to the unit substrate 10. In the present embodiment, the position in the direction parallel to the display surface of the display panel 12 (XY plane direction) is defined.
That is, the positioning member 11 defines the positions of the display modules 9 in the X and Y directions.

The positioning member 11 is slidably connected to the unit substrate 10. That is, the positioning member 11 is not completely fixed to the unit substrate, but is slidably connected within a predetermined range in the XY plane direction.
Further, the plurality of display modules 9 are also slidably supported by the unit substrate 10 in the XY plane direction.
Of course, the plurality of display modules 9 and the positioning member 11 are appropriately connected to the unit substrate 10 to the extent that the display of the image by the display unit 5 does not cause any trouble. On the other hand, a plurality of display modules 9 and positioning members 11 are connected so that they can be slid slightly with respect to the unit substrate 10.
The positioning member 11 is formed of, for example, carbon or the like. In addition, the material of the positioning member 11 is not limited, and any material may be used.

As shown in FIGS. 4 to 6, the display unit 5 includes a plurality of display modules 9, a unit board 10, and a positioning member 11.
The overall shape of each of the plurality of display modules 9, the unit substrate 10, and the positioning member 11 is a flat plate shape. Further, when viewed from the Z direction, the entire outer shapes of the plurality of display modules 9, the unit substrate 10, and the positioning member 11 have rectangular shapes that are substantially equal to each other.
As shown in FIGS. 4 and 6, a display unit 5 is configured by assembling a plurality of display modules 9, a unit board 10, and a positioning member 11 along the Z direction.

In the example shown in FIGS. 4 and 6, a total of eight display modules 9 are arranged, four in the X direction (horizontal direction) and two in the Y direction (vertical direction).
As shown in FIG. 4, the display module 9 has a rectangular display panel 12 having a lateral direction as a lateral direction and a vertical direction as a longitudinal direction. When the display module 9 is viewed along the Z direction, the outer shape also has a rectangular shape similar to that of the display panel 12.

The unit board 10 is configured with a support mechanism for supporting each of the eight display modules 9.
The support mechanism has four contact reference planes and four magnets for one display module 9. These elements will be described in detail later.
Further, the unit substrate 10 is formed with mounting holes for holding the positioning member 11 slidably.

The positioning member 11 has an outer frame portion 16, a central rib portion 17, and three partition rib portions 18.
The outer frame portion 16 is a rectangular frame portion having a hollow inside.
The central rib portion 17 extends in the X direction at the central position in the Y direction and is configured on the inner side of the outer frame portion 16.
The three partition rib portions 18 extend in the X direction so as to be arranged at equal intervals in the Y direction, and are configured on the inner side of the outer frame portion.
The outer frame portion 16, the central rib portion 17, and the three partition rib portions 18 constitute eight openings 19 corresponding to the eight display modules 9. In each opening 19, a portion located on the peripheral edge of the opening 19 is a portion corresponding to the peripheral edge of the back surface portion 13 of the display module 9.

As shown in FIG. 5, the positioning member 11 is connected to the unit substrate 10. As described above, the positioning member 11 is slidably connected to the unit substrate 10.
Therefore, a through hole is formed in the positioning member 11. Further, a stepped screw is used as a member for slidably connecting the positioning member 11 to the unit substrate 10.

[Connection between positioning member and unit board]
The connection between the positioning member 11 and the unit substrate 10 will be described with reference to FIGS. 7 to 9.
In FIGS. 7 to 9, the illustration is centered on the portion related to the connection between the positioning member 11 and the unit substrate 10, and the portion not related to the connection is not shown in some parts.
That is, in each figure, when explaining various features of the display device 100 and the display unit 5 according to the present technology, in order to make it easy to understand the features to be explained, the parts related to the other features are illustrated. May be omitted.
Further, when a plurality of drawings are referred to when explaining a certain feature, the shapes, positions, and the like may be slightly different in each drawing. In such a case, each of the figures can be established as an embodiment according to the present technology.

FIG. 7 is an exploded perspective view showing an enlarged upper right portion of the display unit 5 when the display unit 5 is viewed from the front side.
FIG. 8 is an exploded perspective view of the enlarged portion shown in FIG. 7 when viewed from the rear side.
FIG. 9 is a part of a cross-sectional view when cut in a plane (XZ plane) perpendicular to the Y direction so as to pass through the center of the stepped screw 22 in the enlarged portion shown in FIG. 7.

In this embodiment, the positioning member 11 and the unit board 10 are connected by the stepped screw 22. Specifically, the stepped screw 22 penetrates the through hole 23 formed in the positioning member 11 and is fitted into the mounting hole 24 formed in the unit substrate 10, whereby the positioning member 11 and the unit substrate 10 are formed. Is connected.

As shown in FIG. 7, a plurality of through holes 23 are formed in the positioning member 11.
In this embodiment, a circular through hole 23 is formed. Of course, the specific shape of the through hole 23 is not limited.

In the example shown in FIG. 4, 15 through holes 23 are formed for one positioning member 11.
The through hole 23 is formed in the outer frame portion 16 of the positioning member 11 and the three partition rib portions 18.
As shown in FIG. 4, two through holes 23 are formed on the left side of the rectangular outer frame portion 16. The two through holes 23 are formed at a position above and below the central rib portion 17 in the Y direction, respectively.
Similarly, on the right side of the outer frame portion 16, a total of two through holes 23 are formed, one at a position above the central rib portion 17 and one at a position below the central rib portion 17.

Of the three partition rib portions 18, the partition rib portion 18 located on the leftmost side is formed with four through holes 23. Two through holes 23 are formed at a position above the central rib portion 17 and two at a position below the central rib portion 17 in the Y direction.
In the present embodiment, one of the two through holes 23 formed at the upper position is configured close to the upper side of the outer frame portion 16. Further, one of the two through holes 23 formed below is configured close to the lower side of the outer frame portion 16.
Similarly, four through holes 23 are formed on the partition rib portion 18 located on the far right side.
Three through holes 23 are formed in the partition rib portion 18 located at the center. The three through holes 23 are formed one by one in the vicinity of the upper side of the outer frame portion 16, the vicinity of the lower side of the outer frame portion 16, and the vicinity of the central rib portion 17.

That is, when viewed from the front side, there are two through holes 23 on the left side of the outer frame portion 16, two on the right side of the outer frame portion 16, four on the left partition rib portion 18, and a central partition rib portion. A total of 15 pieces are formed, 3 in 18 and 4 in the left partition rib portion 18.
Of course, the number and positions of the through holes 23 formed in the positioning member 11 are not limited.

In the examples shown in FIGS. 7 and 8, through holes 23 are formed in the vicinity of the right end of the upper side of the outer frame portion 16 and in the vicinity of the upper side of the partition rib portion 18 on the right side.

As shown in FIG. 7, a plurality of mounting holes 24 are formed in the unit substrate 10.
The mounting hole 24 is formed at a position corresponding to the through hole 23 formed in the positioning member 11. For example, when the positioning member 11 is arranged at a desired position with respect to the unit substrate 10, the mounting hole 24 is formed at a position centered on the through hole 23. Of course, the present invention is not limited to this, and the mounting hole 24 may be formed at a position offset from the center of the through hole 23.
In the present embodiment, the mounting hole 24 is formed with a screw thread for fitting with the stepped screw 22.

In the example shown in FIG. 4, 15 mounting holes 24 are formed at positions corresponding to the through holes 23 of the positioning member 11 with respect to the unit substrate 10.
Also in the unit substrate 10 shown in FIG. 7, two mounting holes 24 are formed at positions corresponding to the two through holes 23.
Of course, the number and positions of the mounting holes 24 formed in the unit substrate 10 may be arbitrarily designed according to the number and positions of the through holes 23.

As shown in FIG. 9, the stepped screw 22 has a head portion 27, a stepped portion 28, and a threaded portion 29. The stepped screw 22 is attached so as to face from the front side to the rear side.
The head 27 has a disk shape. The head 27 has a circular front surface and a circular rear surface.
The step portion 28 has a cylindrical shape. The step 28 is connected to the center of the rear surface of the head 27 so as to extend to the rear side. The size of the step 28 in the Z direction is designed according to the thickness of the positioning member 11.
The threaded portion 29 is connected to the center of the rear end surface of the stepped portion 28 so as to extend to the rear side. The screw portion 29 is configured with a screw thread so as to fit into the screw thread of the mounting hole 24 formed in the unit substrate 10.

When the stepped screw 22 is viewed from the front side, the diameter of the head 27, the diameter of the stepped portion 28, and the diameter of the threaded portion 29 decrease in this order. Therefore, a step is formed at the connecting portion between the step portion 28 and the screw portion 29.
The diameter of the step 28 is configured to be larger than the diameter of the mounting hole 24 into which the thread 29 is inserted and fitted. Therefore, when the stepped screw 22 is rotated and fitted to the mounting hole 24, the peripheral portion of the mounting hole 24 (that is, the unit substrate 10) comes into contact with the rear end surface of the stepped portion 28.
Further, the head 27 has a size larger than that of the through hole 23. Specifically, the diameter of the head 27 is configured to be larger than the diameter of the through hole 23 formed in the positioning member 11.
The stepped screw 22 is made of a metal material such as iron. Of course, the material of the stepped screw 22 is not limited, and any material may be used. The stepped screw 22 corresponds to one embodiment of the fitting member according to the present technology, which is fitted into the mounting hole through the through hole and slidably connects the positioning member to the support member.

As shown in FIG. 9, the stepped screw 22 penetrates the through hole 23 formed on the positioning member 11 and is fitted into the mounting hole 24 formed on the unit substrate 10. As a result, the positioning member 11 is sandwiched and fixed between the head portion 27 of the stepped screw 22 and the unit substrate 10.
In the present embodiment, the stepped screw 22 is fitted into the mounting hole 24 so that the positioning member 11 can slide in the X direction and the Y direction with respect to the unit substrate 10. For example, by adjusting the size of the step portion 28 in the Z direction, the positioning member 11 can be connected to the unit substrate 10 to the extent that the positioning member 11 is not too fixed and the fixing force is not too weak. ..
Of course, the amount of rotation when fitting the stepped screw 22 into the mounting hole 24 may be adjusted.

The slidable range of the positioning member 11 with respect to the unit substrate 10 may be defined.
For example, in the example shown in FIG. 9 and the like, the slidable range of the positioning member 11 can be defined by the diameter of the through hole 23 formed in the positioning member 11.
If the diameter of the through hole 23 is increased, the slidable range can be increased. Further, if the diameter of the through hole 23 is reduced, the slidable range can be reduced. In this way, the slidable range may be defined by the diameter (which may be a radius) of the through hole 23.
In addition, an arbitrary configuration for defining the slidable range of the positioning member 11 may be adopted.

An urging member such as a spring may be used to slidably connect the positioning member 11 to the unit substrate 10. For example, the stepped screw 22 is urged toward the unit board 10 by the urging member. By appropriately adjusting the urging force of the urging member, it is possible to adjust the pressing force on which the head 27 of the stepped screw 22 presses the positioning member 11.
In addition, any configuration may be adopted in order to set the pressing force to an appropriate size.

By slidably connecting the positioning member 11 to the unit substrate 10, it is possible to suppress the influence on the positioning member 11 when the unit substrate 10 is deformed or the like.
For example, the unit substrate 10 is formed of a metal such as aluminum. Further, the positioning member 11 is formed of carbon or the like. Metals such as aluminum have a higher coefficient of thermal expansion than carbon and the like, and the rate of change in surface area with temperature changes is higher. Therefore, for example, when the temperature of the space in which the display device 100 is installed rises, the surface area of the unit substrate 10 increases significantly as compared with the surface area of the positioning member 11.
Even when the unit substrate 10 is deformed due to such a difference in the coefficient of thermal expansion, the positioning member 11 slides and slides relative to the unit substrate 10. This makes it possible to suppress the stress generated by the deformation of the unit substrate 10 from being applied to the positioning member 11.

The slidable range of the positioning member 11 may be set in consideration of the amount of deformation of the unit substrate 10.
For example, the diameter of the through hole 23 shown in FIG. 9 is increased to increase the slidable range. As a result, even when the unit substrate 10 is significantly deformed, it is possible to suppress the influence of the deformation on the positioning member 11.
Further, when the amount of deformation of the unit substrate 10 is expected to be small, the diameter of the through hole 23 may be set to be small.

As illustrated in FIG. 5, the positioning member 11 is slidably connected to the unit substrate 10. A plurality of display modules 9 are mounted with reference to the positioning member 11 connected to the unit board 10.
In the example shown in FIG. 4, eight display modules 9 are mounted at the positions of eight openings 19 formed in the positioning member 11.

FIG. 10 is a part of a cross-sectional view when the display unit 5 is viewed from the front side and the upper side portion of the display unit 5 is cut by a plane (XZ plane) perpendicular to the Y direction. Further, FIG. 10 corresponds to a cross-sectional view of the vicinity of the upper right corner of the display unit 5.
FIG. 11 is a perspective view of the cross section shown in FIG. 10 when viewed from the rear side.
FIG. 12 is a perspective view showing a configuration example of the back surface portion 13 of the display module 9. FIG. 12 corresponds to a view of the upper right corner of the upper right display module 9 of the eight display modules 9 shown in FIG. 4 as viewed from the rear side.

The unit board 10 is configured with a support mechanism for supporting the display module 9.
The support mechanism is configured for each display module 9. Specifically, it is configured at a position corresponding to the peripheral edge portion of each opening 19 and supports each display module 9.
In this embodiment, the support mechanism has four magnets 33 and four contact reference surfaces 34.
The four magnets 33 are embedded in the unit substrate 10 at positions corresponding to the four corners of the opening 19. Therefore, a total of 32 magnets 33 are installed on the unit substrate 10.
The four contact reference surfaces 34 are also configured at positions corresponding to the four corners of the opening 19. Therefore, the magnet 33 and the contact reference surface 34 are configured at positions close to each other.

In the example shown in FIG. 4, the unit substrate 10 has an outer frame portion 35 and a bottom surface portion 36. When the unit substrate 10 is viewed from the Z direction, the outer frame portion 35 has a rectangular shape. The bottom surface portion 36 has a planar shape perpendicular to the Z direction, and is connected to the rear side of the outer frame portion 35. The space on the inner side of the outer frame portion 35, and the space on the front side of the bottom surface portion 36 is a space for supporting the plurality of display modules 9.
As shown in FIG. 4, at a predetermined position of the bottom surface portion 36, a support convex portion 37 extending forward along the Z direction is configured. The plurality of support convex portions 37 are configured at positions corresponding to the four corners of each opening 19. The plurality of support convex portions 37 are elements included in the support mechanism.

In the present embodiment, the magnet 33 is embedded in the outer frame portion 35 at positions corresponding to the four corners of each opening 19. Further, the magnet 33 is embedded in the support convex portion 37 configured at the position corresponding to the four corners of each opening 19.
Further, a contact reference surface 34 is formed on the front surface of the outer frame portion 35 at positions corresponding to the four corners of each opening 19 (positions in the vicinity of the magnet 33). Further, a contact reference surface 34 is formed on the front surface of the support convex portion 37 configured at positions corresponding to the four corners of each opening 19.
The height and flatness of the contact reference surface 34 from the bottom surface portion 36 are precisely machined. The plurality of contact reference surfaces 34 formed on the outer frame portion 35 and the support convex portion 37 are formed on the same plane with high accuracy.

As shown in FIGS. 10 and 11, the positioning member 11 has one or more marks configured at predetermined positions for each display module 9. The one or more marks are reference marks when the display module 9 is arranged with respect to the unit board 10.
In the present embodiment, a positioning hole 40 is formed in the peripheral portion of the opening 19 as a mark. For example, positioning holes 40 are formed at the four corners of the peripheral edge of the opening 19. Alternatively, positioning holes 40 are formed at both ends of one side of the peripheral edge portion of the opening 19. Other configurations may be adopted.
Further, the positioning member 11 has four contact through holes 41 for each display module 9. The contact through holes 41 are formed at the four corners of the opening 19 at positions corresponding to the four contact reference surfaces 34 of the unit substrate 10.
When the positioning member 11 is connected to the unit board 10, the four contact reference surfaces 34 of the unit board 10 can be seen from the four contact through holes 41.
On the other hand, when the positioning member 11 is connected to the unit substrate 10, the positions of the four magnets 33 embedded in the unit substrate 10 are covered by the positioning member 11.

As shown in FIG. 12, the back surface portion 13 of the display module 9 includes a magnetic material member 44, a positioning pin 45, and a contact convex portion 46.
The magnetic member 44 is installed at the four corners of the back surface portion 13. The magnetic member 44 is installed at a position corresponding to the four magnets 33 embedded in the unit substrate 10.
The positioning pin 45 is installed at a position corresponding to the positioning hole 40 formed in the positioning member 11.

In the example shown in FIG. 12, in each display module 9, a reinforcing member 47 is provided on the rear side of the display panel 12.
The display panel 12 is formed of a low-strength material such as glass. By connecting the reinforcing member 47, the strength of the display panel 12 is increased, and the destruction due to the impact is prevented.
The reinforcing member 47 is formed of a highly rigid material such as carbon. Of course, the specific configuration such as the material and shape of the reinforcing member 47 is not limited.

The positioning pin 45 is fixed to the reinforcing member 47.
For example, the positioning pin 45 is fixed to the reinforcing member 47 by adhesion using an adhesive or the like. In addition, any fixing method capable of fixing the positioning pin 45 to the reinforcing member 47 may be adopted.
The positioning pin 45 corresponds to one embodiment of the pin member according to the present technology.

The contact reference surface 48 is formed at the rear end of the contact convex portion 46. In the present embodiment, the four contact convex portions 46 are formed at positions corresponding to the four contact through holes 41 formed in the positioning member 11. That is, the four contact convex portions 46 are formed at positions corresponding to the four contact reference surfaces 34 of the unit substrate 10.
The height of the abutting convex portion 46 is precisely machined. That is, the position of the contact reference surface 48 in the Z direction is precisely defined. Further, the flatness of the contact reference surface 48 is also precisely machined. In each display module 9, the plurality of contact reference surfaces 48 are formed on the same plane with high accuracy.

Each of the eight display modules 9 is arranged with respect to the unit substrate 10 so that the positioning pin 45 fits into the positioning hole 40 formed in the positioning member 11.
As a result, the four magnets 33 embedded in the unit substrate 10 and the four magnetic material members 44 arranged on the back surface portion 13 of the display module 9 are attracted by magnetic force. As shown in FIGS. 10 and 11, the magnet 33 and the magnetic member 44 are attracted to each other so as to sandwich the positioning member 11.
In this way, each of the eight display modules 9 is supported by the unit substrate 10 by the magnetic force acting between the magnet 33 and the magnetic member 44. Therefore, the display module 9 is slidably connected to the unit substrate 10 in the X direction and the Y direction.
As the magnetic material, any metal material such as iron may be used. Of course, other magnetic materials may be used. For example, a magnet may be used to be attracted to the magnet 33 embedded in the unit substrate.

Further, the four contact reference surfaces 34 of the unit substrate 10 and the four contact reference surfaces 48 configured on the back surface portion 13 of the display module 9 come into contact with each other.
The contact reference surface 34 and the contact reference surface 48 abut on each other to define the position of each display module 9 with respect to the unit substrate 10 in the Z direction. Since the height and flatness of the contact reference surface 34 and the contact reference surface 48 are precisely defined, each display module 9 is positioned with high accuracy in the Z direction. Further, the display surface of each display module 9 is also aligned in the XY plane direction with high accuracy.
Of course, the heights of the contact reference surface 34 and the contact reference surface 48 may be arbitrarily designed.

In this embodiment, as shown in FIGS. 10 and 11, the positioning pin 45 and the positioning hole 40 are fitted without forming a gap. This makes it possible to perform positioning in the X direction and the Y direction with high accuracy. Further, the positioning member 11 and the plurality of display modules 9 can be integrally slid with respect to the unit substrate 10.
In the Z direction, the length of the positioning pin 45 is set so that a slight gap is formed between the positioning pin 45 and the unit substrate 10. That is, the length of the positioning pin 45 along the Z direction is set so that the tip of the positioning pin 45 does not abut on the front surface of the unit substrate 10 when the display unit 5 is assembled.
This prevents the display module 9 from hindering the contact between the contact reference surface 34 and the contact reference surface 48, which positions the display module 9 in the Z direction. Of course, the length of the positioning pin 45 is determined within a range in which positioning in the X direction and the Y direction is possible.

In the present embodiment, the display module 9 is fixed to the positioning member 11 by fitting the positioning pin 45 and the positioning hole 40. Then, the display module 9 and the positioning member 11 are integrally slidable with respect to the unit substrate 10.
Therefore, for example, when the unit substrate 10 is deformed due to a temperature change or the like, the plurality of display modules 9 and the positioning member 11 can be integrated and slide relative to the unit substrate 10. be. This makes it possible to suppress the stress generated by the deformation of the unit substrate 10 from being applied to the plurality of display modules 9 and the positioning member 11.

Any configuration may be adopted as the configuration of the mark formed on the positioning member 11.
For example, the positioning pin 45 may be formed on the positioning member 11. Then, the positioning hole 40 may be formed in the display module 9. In this case, each display module 9 is arranged with respect to the unit substrate 10 so that the positioning hole 40 fits with the positioning pin 45 formed on the positioning member 11. This makes it possible to accurately position the display module 9 in the X direction and the Y direction.
In addition, any configuration may be adopted.

The positioning member 11 and the display module 9 may be connected by fastening with a fastening member such as a screw, bonding with an adhesive, welding, or the like. Even in this case, the display module 9 and the positioning member 11 are integrally slidable with respect to the unit substrate 10. Therefore, it is possible to suppress the stress generated by the deformation of the unit substrate 10 from being applied to the plurality of display modules 9 and the positioning member 11.
For example, by appropriately designing the mounting position of the fastening member, the coating position of the adhesive, and the like, it is possible to connect the display module 9 to the positioning member 11 while positioning the display module 9 in the X and Y directions. Is. In this case, for example, a screw hole, a recess to which an adhesive is applied, or the like can be made to function as an embodiment of a mark according to the present technology.
As described above, when the display module 9 is arranged with respect to the unit substrate 10, the reference mark is not limited, and any member, an adhesive point, or the like can be used as a mark. Further, the method of arranging the display module 9 with reference to the mark configured on the positioning member is not limited, and any method may be adopted.

[Display module]
The outline of the display module 9 will be described with reference to FIG.

In the example shown in FIG. 12, the reinforcing member 47 is connected to the rear surface 54 of the display panel 12. The support substrate 51 supports the display panel 12 via the reinforcing member 47.
Further, in the example shown in FIG. 12, a contact convex portion 46 having a contact reference surface 48 is formed on the rear surface 54 of the support substrate 51.
The support substrate 51 is made of a metal such as aluminum. In addition, the material of the support substrate 51 is not limited, and any material may be used.

The adjusting mechanism 52 is connected to each of the display panel 12 and the support board 51, and the relative distance of the display panel 12 to the support board 51 can be adjusted. For example, in the example shown in FIG. 12, the adjusting mechanism 52 makes it possible to adjust the distance from the contact reference surface 48 formed on the support substrate 51 to the display surface 53 of the display panel 12.
As described above, in the example shown in FIG. 12 and the like, the contact reference surface 48 of the contact convex portion 46 formed on the support substrate 51 and the contact reference surface of the support convex portion 37 formed on the unit substrate 10. The contact with 34 defines the position of the display module 9 with respect to the unit substrate 10 in the Z direction.
In the present embodiment, the adjustment mechanism 52 further makes it possible to adjust the position of the display panel 12 with respect to the support substrate 51 in the Z direction. As a result, it is possible to adjust the position, inclination, and the like of the display surface 53 of the display panel 12 in the Z direction.
As a result, as shown in FIG. 4, when a plurality of display panels 12 are arranged side by side, it is possible to align the display surfaces 53 on the same surface.

[Adjustment mechanism]
The adjusting mechanism 52 will be described with reference to FIGS. 10 to 12 and 14 to 16.
FIG. 14 is an exploded perspective view of the display module 9 when viewed from the front side.
FIG. 15 is a part of a cross-sectional view when the upper side of the display module 9 is cut along a plane (XZ plane) perpendicular to the Y direction so as to pass through the center of the adjusting mechanism 52. FIG. 15 is a cross-sectional view near the position of the upper left corner of the display module 9.
FIG. 16 is an exploded perspective view of the display module 9 when viewed from the rear side. FIG. 16 is an exploded perspective view of a portion corresponding to the upper right portion of the display module 9.

As shown in FIG. 14, when viewed from the direction perpendicular to the display surface 53 (Z direction), the outer shapes of the display panel 12 and the support substrate 51 are rectangular shapes substantially equal to each other. Therefore, the peripheral edge portion 57 of the display panel 12 is supported by the peripheral edge portion 58 of the support substrate 51.
In the present embodiment, 14 adjusting mechanisms 52 are configured between the peripheral edge portion 57 of the display panel 12 and the peripheral edge portion 58 of the support substrate 51.

As shown in FIGS. 14 to 15, a mounting mechanism 59 for mounting the adjusting mechanism 52 is configured on the peripheral edge portion 58 of the support substrate 51.
The mounting mechanism 59 has a mounting recess 60 having a concave shape toward the front side when the support board 51 is viewed from the rear side. When the mounting recess 60 is viewed from the rear side along the Z direction, the outer shape is circular.
The mounting recess 60 has a flat plate portion 61 that is the bottom surface of the recess, and a side wall portion 62 that extends rearward from the flat plate portion 61. The flat plate portion 61 is a flat plate-shaped member arranged in parallel with the display surface 53.
Further, in the mounting recess 60 of the mounting mechanism 59, a through hole 63 for the adjusting mechanism for mounting the adjusting mechanism 52 is formed.

The mounting mechanism 59 is formed at the following 14 locations.
4 corners (4 locations) of peripheral edge 58
Two short sides (upper side and lower side) of the peripheral edge 58, two places on the center side of both ends (four places in total)
Two long sides (left side and right side) of the peripheral portion 58, three places from both ends to the center side (six places in total)
Focusing on each of the short side and the long side of the peripheral edge portion 58, the mounting mechanism 59 is formed at one or more positions between both ends. Both ends of the short side and the long side correspond to the positions of the four corners of the peripheral edge portion 58.

As shown in FIG. 14, the two positions on the center side of the two short sides are two positions substantially in the middle between both ends and the center.
On the two long sides, the three positions on the center side are one position in the center and two positions approximately in the middle between both ends and the center.
When the display module 9 is viewed from the front, the position of the through hole 63 for the adjustment mechanism corresponds to the position of the adjustment mechanism 52. The position and number of adjustment mechanisms 52 are not limited to one display module 9, and may be arbitrarily designed.

In the present embodiment, the adjusting mechanism 52 has a male screw stud 66, a female screw 67, a torsion coil spring 68, a lid member 69, and a lid set screw 70.
The male screw stud 66 has a head 71 and a male screw portion 72 on which a thread is formed. The male screw portion 72 is connected to the center of the head 71.
The head 71 of the male screw stud 66 is installed on a reinforcing member 47 connected to the rear side of the display panel 12 so that the male screw portion 72 extends to the rear side. The male screw stud 66 is connected to the reinforcing member 47 so that the central axis coincides with the center of the through hole 63 for the adjusting mechanism.
The head 71 of the male screw stud 66 is fixed to the reinforcing member 47, for example, by fastening with a fastening member such as a screw. In addition, any fixing method capable of fixing the male screw stud 66 to the reinforcing member 47, such as adhesion using an adhesive or welding, may be adopted.
The male screw stud 66 is made of a metal material such as iron. Of course, the material of the male screw stud 66 is not limited, and any material may be used.
The male screw stud 66 corresponds to an embodiment of a connecting member attached to a display panel and connected to a screw according to the present technology.

The female screw 67 has a head 73 and a hollow cylindrical portion 74. The hollow portion of the cylindrical portion 74 is configured as a screw hole that engages with the male screw portion 72. Further, a through hole 75 is also formed in the central portion of the head 73, and is connected to the screw hole.
The female screw 67 is arranged inside the mounting recess 60 so that the cylindrical portion 74 extends toward the front side. The female screw 67 is arranged so that the central axis coincides with the center of the through hole 63 for the adjusting mechanism, that is, coincides with the central axis of the male screw stud 66.
In the present embodiment, the head 73 of the female screw 67 is attached to the front surface of the lid member 69. Further, the rotating member 76 is connected to the female screw 67 from the rear side of the lid member 69 so as to sandwich the lid member 69. In the example shown in FIG. 15, the front end portion of the rotating member 76 is inserted and fixed into the through hole 75 of the head 73 of the female screw 67. The female screw 67 and the rotating member 76 are configured to be rotatable with respect to the lid member 69.
For example, a groove (for example, a plus groove or a minus groove) that can be engaged with a screwdriver is formed on the rear surface of the rotating member 76. The user can rotate the female screw 67 by rotating the rotating member 76 using a screwdriver or the like. Of course, any other configuration may be adopted as the configuration for rotating the female screw 67.
In addition, in FIG. 16, the illustration of the rotating member 76 is omitted.
The female screw 67 is made of a metal material such as iron. Of course, the material of the female screw 67 is not limited, and any material may be used.
The female screw 67 corresponds to an embodiment of a screw attached to a support substrate according to the present technology.

The lid member 69 is connected to the support substrate 51 so that the female screw 67 to be mounted on the front side is arranged at the center of the mounting recess 60.
In the example shown in FIG. 14 and the like, the lid member 69 is connected to the support substrate 51 by the lid set screw 70 at two predetermined positions around the mounting recess 60.
As shown in FIG. 15, when the lid member 69 of the adjusting mechanism 52 configured at the four corners of the support substrate 51 and the lid member 69 of the adjusting mechanism 52 configured at a position adjacent to the lid member 69 are viewed from the Z direction. The shapes of are different from each other. As described above, each adjusting mechanism 52 may have a different shape or the like of each member constituting the adjusting mechanism 52.
In the present embodiment, the lid member 69 is a member corresponding to the magnetic material member 44 shown in FIG. 12 and the like. That is, in the present embodiment, the lid member 69 and the magnet 33 embedded in the unit substrate 10 are attracted to each other. In this way, the member constituting the adjusting mechanism 52 may also be used as a member for connecting the display unit 5 to the unit substrate 10. This makes it possible to reduce the number of parts and simplify the configuration.
The lid member 69 is made of a metal material such as iron. Of course, the material of the lid member 69 is not limited, and any material may be used.
The lid member 69 corresponds to an embodiment of a fixing member according to the present technology, which holds a screw rotatably and is fixed to a support substrate. The female screw 67 is rotatably attached to the support substrate 51 via the lid member 69.

The torsion coil spring 68 is arranged between the flat plate portion 61 and the lid member 69 in the mounting recess 60. One end of the torsion coil spring 68 is connected to the flat plate portion 61, and the other end is connected to the head 73 of the female screw 67. Therefore, the torsion coil spring 68 urges the female screw 67 toward the lid member 69. This makes it possible to prevent backlash between the male screw portion 72 and the female screw 67.
The specific material and shape of the torsion coil spring 68 are not limited. The torsion coil spring 68 corresponds to one embodiment of the urging member according to the present technology, which is arranged between the fixing member and the flat plate portion and urges the screw in the direction of the fixing member.
The member for urging the female screw 67 in the direction of the lid member 69 is not limited to the torsion coil spring 68. For example, a disc spring, rubber, or the like may be used, and the female screw 67 may be urged in the direction of the lid member 69. In addition, the method for encouraging is not limited, and any method may be adopted.

As shown in FIG. 15 and the like, the male screw stud 66 and the female screw 67 are connected to each other via a through hole 63 for an adjusting mechanism. In the example shown in FIG. 15, the male screw portion 72 of the male screw stud 66 penetrates the through hole 63 and extends to the rear side. Of course, the present invention is not limited to this, and the cylindrical portion 74 of the female screw 67 may be configured to penetrate the through hole 63.
When attaching the lid member 69 to the support substrate 51, the rotating member 76 is appropriately rotated to fit the male screw stud 66 and the female screw 67. Then, the lid member 69 is fixed to the support substrate 51 by the lid set screw 70.

As shown in FIG. 14 and the like, a through hole 77 for the positioning pin through which the positioning pin 45 penetrates is formed on the peripheral edge of the support substrate 51. The through hole 77 for the positioning pin is formed at a position where the positioning pin 45 is mounted.

[Adjusting the height of the display panel by the adjustment mechanism]
The height adjustment of the display panel 12 by the adjustment mechanism 52 will be described with reference to FIG.
In the present embodiment, the adjusting mechanism 52 adjusts the relative distance of the display panel 12 with respect to the support substrate 51 in the direction perpendicular to the display surface.
Hereinafter, the adjustment of the relative distance of the display panel 12 with respect to the support substrate 51 in the direction perpendicular to the display surface 53 is adjusted, the height of the display panel 12 with respect to the support substrate 51 is adjusted, or the height of the display panel 12 is simply adjusted. May be expressed as.

In this embodiment, the height of the display panel 12 is adjusted by the relative rotation of the female screw 67 with respect to the male screw stud 66.
For example, the rotating member 76 is rotated by using a tool such as a screwdriver. Since the rotating member 76 and the female screw 67 are connected to each other, when the rotating member 76 is rotated, the female screw 67 also rotates integrally.
The male screw stud 66 is fixed to the reinforcing member 47 so as not to rotate. Therefore, by rotating the female screw 67, the fitting position (fitting depth) between the male screw stud 66 and the female screw 67 is adjusted. Therefore, the front end portion of the male screw stud 66 moves to the front side or the rear side relative to the female screw 67.
For example, when the female screw 67 is rotated clockwise, the male screw stud 66 moves forward. When the female screw 67 is rotated counterclockwise, the male screw stud 66 moves to the rear side. Of course, the relationship between the rotation direction of the female screw 67 and the direction of movement of the male screw stud 66 along the Z direction may be opposite.

The female screw 67 is fixed to the support substrate 51 via the lid member 69. Further, the male screw stud 66 is fixed to the reinforcing member 47. Therefore, when the male screw stud 66 moves forward or backward along the Z direction, the relative distance of the display panel 12 with respect to the support substrate 51 in the direction perpendicular to the display surface is adjusted.
In the present embodiment, the display surface 53 of the display panel 12 can be moved backward by rotating the female screw 67 clockwise. By rotating the female screw 67 counterclockwise, the display surface 53 of the display panel 12 can be moved to the front side.
That is, in the present embodiment, the height of the display panel 12 with respect to the support substrate 51 can be lowered by rotating the female screw 67 clockwise. Further, by rotating the female screw 67 counterclockwise, it is possible to increase the height of the display panel 12 with respect to the support substrate 51. By rotating the female screw 67 in this way, the height of the display panel 12 with respect to the support substrate 51 is adjusted.

The height adjustment of the display panel 12 is performed by using a dedicated jig or the like before mounting the display module 9 on the unit board 10. For example, the support substrate 51 is fixed by a jig, and the female screw 67 of each adjustment mechanism 52 is rotated. Of course, it is not limited to such an adjustment method.
In the example shown in FIG. 14, 14 adjusting mechanisms 52 are configured on the peripheral edge portion 58 of the display panel 12 and the support substrate 51. By rotating the female screw 67 in each adjustment mechanism 52, the height of the display panel 12 at the position where the adjustment mechanism 52 is configured can be adjusted.
For example, the distance from the contact reference surface 48 of the contact convex portion 46 shown in FIG. 12 or the like to the display surface 53 is defined as the height of the display panel 12. Further, a design value is determined for the height of the display panel 12.
After connecting the display panel 12 and the support board 51, the height of the display panel 12 can be adjusted to the design value over the entire area of the display surface 53 by operating the adjustment mechanisms 52 at 14 locations. Is. The design value corresponds to a predetermined value.

In this embodiment, eight display modules 9 are arranged for one unit board 10.
When assembling the display unit 5, the height of the display panel 12 is adjusted to the design value by operating the adjustment mechanism 52 in each of the plurality of display modules 9 in advance. That is, before mounting the display module 9 on the unit board 10, the height of the display panel 12 of each display module 9 is adjusted to the same height.

A plurality of display modules 9 having the same height of the display panel 12 are connected to the unit board 10 with the positioning member 11 as a reference. The contact reference surface 48 in the display module 9 and the contact reference surface 34 of the unit substrate 10 are in contact with each other, and the position of the display module 9 with respect to the unit substrate 10 in the Z direction is defined.
Since the heights of the display panels 12 are aligned in each display module 9, the display surfaces 53 of the eight display modules 9 are arranged on the same surface. This makes it possible to display a high-quality image.

For example, it is assumed that the heights of the display panels 12 of the display modules 9 are different and the display surfaces 53 are not arranged on the same surface. In this case, when the user views the image displayed by the display device 100, a bright line or a dark line may be recognized due to a step between adjacent display surfaces 53 or the like.
For example, it is assumed that the display surface 53 on the right side of the two display panels 12 arranged side by side is located on the front side of the display surface 53 on the left side. When the user views the display device 100 from the front right, the right end portion of the left display panel 12 is blocked by the left end portion of the right display panel 12. As a result, dark lines are generated at the joints of the left and right display panels 12 and are seen.
The emission line is also generated due to the step between the adjacent display surfaces 53.

In the display device 100 according to the present technology, it is easily realized that a plurality of display surfaces 53 are arranged on the same surface by operating the adjustment mechanism 52. As a result, it is possible to sufficiently suppress the generation of bright lines and dark lines, and it is possible to display a high-quality image.

Further, by configuring the adjusting mechanism 52 at a plurality of positions as in the present embodiment, it is possible to suppress deterioration of the flatness of the display panel 12, for example.
In this embodiment, the reinforcing member 47 is adhered to the display panel 12 with, for example, an adhesive. Due to the curing and shrinkage of the adhesive, stress may be generated on the display panel 12, the display panel 12 may be distorted, and the flatness may be deteriorated.
That is, when one display panel 12 is viewed from the X direction or the Y direction, the display panel 12 may have a difference in height in the Z direction and may appear wavy.
By configuring a plurality of adjusting mechanisms 52 on each side, it is possible to sufficiently suppress such a difference in height, and it is possible to sufficiently suppress deterioration of the flatness of the display panel 12.
The number of adjusting mechanisms 52 is increased, and the interval at which the adjusting mechanisms 52 are arranged is reduced. As a result, the height of the display panel 12 can be adjusted with extremely high accuracy, and good flatness can be easily realized. As a result, it is possible to display a high-quality image.
On the other hand, by reducing the number of adjustment mechanisms 52, it is possible to simplify the configuration of the display module 9, reduce the number of parts, reduce the cost of parts, and the like. For example, the number of adjusting mechanisms 52 may be appropriately set based on such trade-off matters.

Hereinafter, each peripheral edge of the display panel 12 may be referred to as a ridgeline of the display panel 12.
In the present embodiment, the display panel 12 is formed of a material having low ridge line straightness accuracy, such as a glass substrate subjected to a semiconductor process such as a thin film transistor. That is, the straightness of the side of the display panel 12 tends to change due to the application of stress.
Even when the display panel 12 is formed of a material having a low ridgeline straightness accuracy, the flatness of the display panel 12 can be maintained high by arranging a plurality of adjustment mechanisms 52. This makes it possible to form a circuit for the display panel 12 by a semiconductor process, and it is possible to reduce the manufacturing cost.
Further, even when a material such as a composite material having low ridgeline straightness accuracy and easily expanding and contracting due to temperature change and humidity change is used for the display panel 12, deterioration of the flatness of the display panel 12 is suppressed and high. High quality images can be displayed.

Further, in the display device 100 according to the present technology, the height of each display panel 12 is adjusted in advance by the adjustment mechanism 52, and the display unit 5 is assembled by a method in which the display module 9 is attached to the unit board 10 after the adjustment. Be done.
Further, when connecting a plurality of display units 5, the heights of all the display panels 12 can be made uniform by aligning the heights of the four corners of each display unit 5.
This makes it possible to assemble the display unit 5 in a short time. In addition, since the work time is shortened, it is possible to reduce the installation cost such as the labor cost related to the installation.

For example, when the display module 9 is attached to the display unit 5, a method of aligning the heights of the display panels 12 is used. In this method, for example, when a problem occurs in the display module 9 and a substitute display module 9 is installed, it is necessary to adjust the height of the display panel 12 each time.
In the display device according to the present technology, it is not necessary to adjust the height of the display panel 12 when the display module 9 is attached. As a result, the working time when a defect occurs can be shortened, and the time during which the display device 100 cannot operate can be shortened. Further, it is possible to reduce service costs such as labor costs related to the replacement of the display module 9.

Stress may be generated on the display panel 12 of the display module 9 due to changes in temperature and humidity. When the display panel 12 is deformed due to the stress, it becomes difficult to display a high-quality image.
In the present embodiment, the display panel 12 is sufficiently fixed to the support substrate 51 by fitting the male screw stud 66 and the female screw 67 included in the adjusting mechanism 52. This makes it possible to prevent the display panel 12 from being deformed.
As described above, by using the adjusting mechanism 52 using the male screw stud 66 and the female screw 67, it is possible to suppress the deformation of the display panel 12.
In addition, various deformations such as tilt and distortion of each display panel 12 and displacement of the position in the X direction or the Y direction are suppressed. As a result, the uniformity of the image quality of the image displayed by the display device 100 is improved, and high-quality image display is realized.

In this embodiment, as shown in FIG. 15, the female screw 67 and the male screw stud 66 are connected to each other via a through hole 63 for an adjusting mechanism. That is, the male screw portion 72 of the male screw stud 66 penetrates the through hole 63 for the adjustment mechanism and fits with the female screw 67.
The diameter of the through hole 63 for the adjusting mechanism is set to a size that does not come into contact with the female screw 67 and the male screw stud 66. Therefore, the through hole 63 is configured to have a gap between the adjusting mechanism 52 and the support substrate 51, and the adjusting mechanism 52 is penetrated without contacting the adjusting mechanism 52 and the support substrate 51. That is, the female screw 67 and the male screw stud 66 are configured apart from the support substrate 51.
This prevents the through hole 63 from coming into contact with the adjusting mechanism 52 and transmitting stress to the display panel 12 when the support substrate 51 is deformed.

The display panel 12 is made of, for example, glass. The support substrate 51 is made of, for example, aluminum. Since the coefficient of thermal expansion of aluminum is extremely higher than the coefficient of thermal expansion of glass, for example, when the temperature of the display device 100 rises, the support substrate 51 expands relatively large with respect to the display panel 12.
For example, if a gap is not provided between the adjusting mechanism 52 and the support substrate 51, stress is transmitted to the display panel 12 as the support substrate 51 expands. As a result, the display panel 12 may be deformed.

In the present embodiment, since there is a gap between the male screw stud 66 and the support substrate 51, the male screw stud 66 and the support substrate 51 do not come into contact with each other. Therefore, the support substrate 51 does not give stress to the male screw stud 66. As a result, deformation of the display panel 12 and the like is suppressed, and a high-quality image can be displayed.
The diameter of the through hole 63 for the adjustment mechanism is set sufficiently large so that the support substrate 51 and the male screw stud 66 do not come into contact with each other due to the expansion of the support substrate 51. Specifically, for example, in consideration of the coefficient of thermal expansion of the support substrate 51, the range in which the temperature of the support substrate can be taken, and the like, how much the support substrate 51 can expand is calculated, and the size of the diameter is set. Of course, the diameter of the through hole 63 may be set by any method.

Further, in the present embodiment, as shown in FIGS. 10 and 11, the positioning pin 45 penetrates the positioning pin through hole 79 and fits into the positioning hole 40 configured in the positioning member 11.
The positioning pin through hole 79 is configured to have a gap between the positioning pin 45 and the support substrate 51. This prevents the positioning pin through hole 79 from coming into contact with the positioning pin 45 when the support substrate 51 is deformed or the like.
As a result, when the support substrate 51 is deformed or the like, stress is prevented from being transmitted to the display panel 12. As a result, deformation of the display panel 12 and the like is suppressed, and a high-quality image can be displayed.
The diameter of the positioning pin through hole 79 is set sufficiently large so that the support substrate 51 and the positioning pin 45 do not come into contact with each other due to the expansion of the support substrate 51.

17 and 18 are cross-sectional views showing another configuration example of the adjusting mechanism 52.
In the adjustment mechanism 52 shown in FIG. 17, the female screw 67 is fixed to the reinforcing member 47 on the display panel 12 side, and the male screw stud 66 is rotatably connected to the lid member 69.
The head 73 of the female screw 67 is fixed to the reinforcing member 47 connected to the display panel 12. The female screw 67 is provided so that the cylindrical portion 74 having a screw hole extends to the rear side.
The head 71 of the male screw stud 66 is connected to the front surface of the lid member 69. The male screw stud 66 is provided so that the male screw portion 72 extends to the front side.
A mounting hole is formed in the center of the head 71 of the male screw stud 66. The rotation member 76 is arranged from the rear side of the lid member 69 and is fixed to the mounting hole of the head 71 of the male screw stud 66. As a result, the male screw stud 66 and the rotating member 76 can be integrally rotated.
A torsion coil spring 68 is provided between the flat plate portion 61 of the mounting recess 60 of the support substrate 51 and the head 71 of the male screw stud 66. The torsion coil spring 68 urges the male screw stud 66 toward the lid member 69.
The user rotates the rotating member 76 by using a driver or the like. This makes it possible to adjust the position of the female screw 67 in the Z direction. As a result, the height of the display panel 12 can be adjusted.
As shown in FIG. 17, the size of the through hole 63 of the flat plate portion 61 is designed so that there is a gap between the flat plate portion 61 and the female screw 67. This makes it possible to prevent stress from being transmitted to the display panel 12 due to deformation of the support substrate 51 or the like.
In the adjusting mechanism 52 shown in FIG. 17, the male screw stud 66 corresponds to an embodiment of a screw rotatably attached to a support substrate. Further, the female screw 67 corresponds to an embodiment of a connecting member attached to the display panel and connected to the screw.

In the adjustment mechanism 52 shown in FIG. 18, the magnet 82 is fixed to the reinforcing member 47 on the display panel 12 side. Further, a male screw stud 66 is rotatably connected to the lid member 69.
The head 71 of the male screw stud 66 is connected to the front surface of the lid member 69. The male screw stud 66 is provided so that the male screw portion 72 extends to the front side.
The male screw stud 66 is connected to the rotating member 76 so as to sandwich the lid member 69. As a result, the male screw stud 66 and the rotating member 76 can rotate integrally with the lid member 69.
The male screw stud 66 has a male screw portion 72 whose tip portion is at least made of a magnetic material. When the magnet 82 and the tip of the male screw portion 72 are brought into contact with each other, both are attracted by magnetic force.
For example, the tip of the male screw portion 72 is made of a magnetic material such as cobalt or nickel. The entire male screw portion 72 or the entire male screw stud 66 may be made of a magnetic material.

A screw hole into which the male screw portion 72 of the male screw stud 66 is fitted is formed in the flat plate portion 61 of the mounting recess 60 of the support substrate 51. By rotating the rotating member 76, the tip of the male screw portion 72 can move along the Z direction. That is, the male screw portion 72 is connected to the support substrate 51 so that the tip portion can be moved by rotating.
A torsion coil spring 68 is provided between the flat plate portion 61 of the mounting recess 60 of the support substrate 51 and the head 71 of the male screw stud 66. The torsion coil spring 68 urges the male screw stud 66 toward the lid member 69. This makes it possible to prevent backlash between the screw hole and the male screw portion 72.
The user rotates the rotating member 76 by using a driver or the like. This makes it possible to adjust the position of the tip of the male screw portion 72 and the magnet 82 adjusted to the tip in the Z direction. As a result, the height of the display panel 12 can be adjusted.
For example, it is assumed that the support substrate 51 is deformed due to a temperature change or the like. In this case, stress may be transmitted from the screw hole of the flat plate portion 61 to the male screw portion 72. On the other hand, the tip of the male screw portion 72 and the magnet 82 are attracted by a magnetic force. That is, the tip of the male screw portion 72 and the magnet 82 are slidably connected.
Therefore, in each adjusting mechanism 52, it is possible to slide integrally with the reinforcing member 47 and the display panel 12 to which the magnet 82 is fixed according to the deformation of the support substrate 51 or the like. This makes it possible to prevent stress from being transmitted to the display panel 12.
In the adjustment mechanism 52 shown in FIG. 18, the male screw stud 66 corresponds to an embodiment of a screw whose tip portion is made of a magnetic material and whose tip portion is movably attached to a support substrate by rotation. Further, the magnet 82 corresponds to an embodiment of a connecting member attached to a display panel and connected to a screw.

[Arrangement of contact reference surface]
FIG. 19 is a perspective view of the unit substrate 10 when viewed from the front side.
As shown in FIG. 19, the unit substrate 10 is configured with a support convex portion 37 having a contact reference surface 34 at positions corresponding to the four corners of the display panel 12. Therefore, the contact reference surface 34 on the unit substrate 10 side is configured at positions corresponding to the four corners of the display panel 12.
The support board 51 is configured with a contact convex portion 46 having a contact reference surface 48 at positions corresponding to the four corners of the display panel 12 (that is, the positions of the four corners of the support board 51). Therefore, the contact reference surface 48 on the display module 9 side is configured at the four corners of the display panel 12.
The contact reference surface 34 on the unit board 10 side and the contact reference surface 48 on the display module 9 side come into contact with each other to define the position of each display module 9 with respect to the unit board 10 in the Z direction.
Here, the entire support convex portion 37 and the contact convex portion 46 in a state where the contact reference surface 34 and the contact reference surface 48 are in contact with each other are referred to as a Z positioning mechanism 85. Further, the sum of the sizes (heights) of the support convex portion 37 and the contact convex portion 46 in the Z direction, that is, the height of the Z positioning mechanism 85 is defined as the reference height.
The position of each display module 9 in the Z direction with respect to the unit substrate 10 is defined by the Z positioning mechanism 85. Further, the height of the Z positioning mechanism 85, that is, the reference height is the height with respect to the unit substrate 10.

FIG. 20 is a schematic diagram for explaining the position of the Z positioning mechanism 85 with respect to each display module 9.
As described above, the heights of the support convex portion 37 and the contact convex portion 46 are precisely machined. This makes it possible to precisely process the reference height of the Z positioning mechanism 85.
On the other hand, when a plurality of Z positioning mechanisms 85 are configured with respect to the display panel 12, a tolerance α may occur at the reference height of each Z positioning mechanism 85.

For example, as shown in FIG. 20, it is assumed that two Z positioning mechanisms 85 are configured. Further, the distance between the two Z positioning mechanisms 85 is L1.
In this case, the inclination θ of the display module 9 generated by the tolerance α is expressed by the following equation.
tan θ = α / L1 ... (1)

Further, the amount of change in the support position by the Z-positioning mechanism 85 (the amount of change from the original support position of the Z-positioning mechanism 85) Δh at the end of the display module 9 in the vicinity of the Z-positioning mechanism 85 is given by the following equation. expressed. L2 is the distance from the Z positioning mechanism 85 to the end.
Δh = L2tanθ ... (2)
In the figure, the distances L1 and L2 are defined with reference to the center position of the Z positioning mechanism 85 on the XY plane.

Substituting tan θ of equation (1) into equation (2) yields the following equation.
Δh = α · L2 / L1 ... (3)
Therefore, it can be seen that it is effective to increase L1 and decrease L2 in order to suppress the fluctuation of the position of the end portion of the display module 9 in the Z direction due to the tolerance α.

In consideration of this point, by configuring the Z positioning mechanism 85 at the position of the peripheral edge portion 58 of the display panel 12, it is possible to suppress the fluctuation of the position of the display surface 53 in the Z direction due to the tolerance α. That is, by forming the abutting convex portion 46 on the peripheral edge portion 57 of the support substrate 51, it is possible to suppress the fluctuation of the position of the display surface 53 in the Z direction.

In the present embodiment, the contact convex portions 46 are configured at the four corners of the support substrate 51. As a result, fluctuations in the position of the display surface 53 in the Z direction due to the tolerance α are sufficiently suppressed. Further, since the Z positioning mechanism 85 is configured by the positions of the four corners of the display module 9, the display module 9 can be stably supported.
Each of the plurality of display modules 9 has the same configuration as each other. Therefore, the Z positioning mechanism 85 (contact convex portion 46 and support convex portion 37) is configured at the four corners of each display module 9. Therefore, the support convex portion 37 is provided close to each other with respect to the support convex portion 37 for the adjacent display module 9. This corresponds to the contact convex portion 46 on the display module 9 side being provided close to the contact convex portion 46 of the adjacent display module 9.
For example, suppose that the display unit 5 is viewed from the front along the Z direction. In this case, the Z positioning mechanism 85 (contact convex portion 46 and support convex portion 37) configured at the position of the lower left corner of the display panel 12 at the right end of the upper row is the lower right corner of the display panel 12 second from the right in the upper row. It is close to the Z positioning mechanism 85 (contact convex portion 46 and support convex portion 37) configured at the position of. Further, it is close to the Z positioning mechanism 85 (contact convex portion 46 and support convex portion 37) configured at the position of the upper left corner of the display panel 12 at the lower right end. Further, it is close to the Z positioning mechanism 85 (contact convex portion 46 and support convex portion 37) configured at the position of the upper right corner of the display panel 12 second from the right in the lower row.
In this way, the Z positioning mechanism 85 (contact convex portion 46 and support convex portion 37) is installed close to the display modules 9 adjacent to each other. This makes it possible to sufficiently suppress fluctuations in the position of the display surface 53 in the Z direction due to the tolerance α.
Of course, it is not limited to the case where the tolerance α is generated, and it is possible to sufficiently suppress the influence even when the reference height of the Z positioning mechanism 85 varies due to aging deterioration, temperature change, or the like. ..
Further, the Z positioning mechanism 85 (contact convex portion 46 and support convex portion 37) may be configured at positions other than the four corners of the peripheral edge portion 58 of the display panel 12.

The abutting convex portion 46 corresponds to one embodiment of one or more abutting portions configured on the peripheral edge portion of the support substrate and abutting against the support member according to the present technology.
Further, the contact reference surface 48 corresponds to one embodiment of the contact surface that comes into contact with the support member according to the present technology.

[Unit board connection]
As shown in FIG. 2, in the present embodiment, the display device 100 has nine display units 5. The display units 5 are arranged so as to be arranged in a two-dimensional grid pattern, three in the X direction (horizontal direction) and three in the Y direction (vertical direction).
By connecting each display unit 5, the display device 100 is configured.

FIG. 21 is a flowchart showing an example of a connection method for connecting a plurality of display units 5 to each other.
As a first connection step, a plurality of unit boards 10 included in the plurality of display units 5 are connected to each other (step 101). In the present embodiment, each unit board 10 of the nine display units 5 is connected. That is, the nine unit substrates 10 are connected to each other so as to be arranged in a two-dimensional grid pattern.
As a second connection step, a plurality of positioning members 11 included in the plurality of display units 5 are connected to each other (step 102). In the present embodiment, each positioning member 11 of the nine display units 5 is connected. That is, the nine positioning members 11 are connected to each other so as to be arranged in a two-dimensional grid pattern.
As a third connection step, a plurality of unit boards 10 connected to each other and a plurality of positioning members 11 connected to each other are connected (step 103). That is, the nine connected positioning members 11 are collectively attached to the nine connected unit boards 10.
Next, the display module 9 is attached (step 104). That is, the display module 9 is attached to the nine positioning members 11 and the nine unit boards 10 that are connected. In this embodiment, eight display modules 9 are attached to one unit board 10. Therefore, 72 display modules 9 are attached to the nine unit boards 10.

An example of the first connection step of step 101 will be described with reference to FIGS. 22 to 25.
FIG. 22 is a perspective view of the unit substrate 10 when viewed from the upper right on the front side.
FIG. 23 is a perspective view of the unit substrate 10 when viewed from the upper right on the front side, and is a view showing the unit substrate connecting plate 88 in an exploded perspective view.
FIG. 24 is a perspective view of the unit substrate 10 when viewed from the upper left side on the rear side, and is a view showing the unit substrate connecting plate 88 in an exploded perspective view.
FIG. 25A is an enlarged perspective view showing a portion to which the unit board connecting plate 88 is attached when the unit board 10 is viewed from the front side.
FIG. 25B is a cross-sectional view when the unit substrate 10 to which the unit substrate connecting plate 88 is attached is cut along a plane (XZ plane) perpendicular to the Y direction so as to pass through the center of the unit substrate connecting plate 88.
The unit substrate 10 shown in FIGS. 22 to 25 has a different configuration from the unit substrate 10 shown in FIGS. 19 and the like. 22 to 25 are views of the unit substrate 10 in a state where the positioning member 11 is not connected.

In this embodiment, the unit substrate connecting plate 88 is used to connect the unit substrate 10.
As shown in FIGS. 22 to 24, the unit board connecting plate 88 has two screws 89 and a connecting portion 90.
FIG. 25B shows a cross-sectional view of the unit substrate connecting plate 88 in a state where the unit substrate connecting plate 88 is attached.
As shown in FIG. 25B, the screw 89 has a head 91 and a screw portion 92.
The head 91 has a disk shape. The head 91 has a circular front surface and a circular rear surface.
The screw portion 92 is connected to the center of the rear surface of the head 91 so as to extend to the rear side. A screw thread is formed in the screw portion 92.
The screw 89 is made of a metal material such as iron. Of course, the material of the screw 89 is not limited, and any material may be used.

The connecting portion 90 has a flat plate shape having a substantially rectangular shape when viewed from the Z direction, and has a front surface and a rear surface.
As shown in FIG. 25A, two insertion holes 93 are configured on the front surface of the connecting portion 90. The insertion hole 93 is a hole for inserting the screw 89.
The insertion hole 93 is configured as a recess having a circular bottom surface. That is, the insertion hole 93 has a circular surface as the bottom surface of the recess when the connecting portion is viewed from the front side. Further, at the center of the bottom surface of the recess, there is a through hole 94 having a circular shape when viewed from the front side. The through hole 94 penetrates the connecting portion 90.

As shown in FIG. 25B, the diameter of the bottom surface of the recess of the connecting portion 90 is configured to be larger than the diameter of the head 91 of the screw 89. Further, the diameter of the through hole 94 formed in the bottom surface of the recess is set to be larger than the diameter of the screw portion 92 of the screw 89 and smaller than the diameter of the head 91.
Further, the height of the recess of the insertion hole 93, that is, the length of the recess in the Z direction is set to be larger than the height of the head 91 of the screw 89. Further, the height of the through hole 94 is set to be smaller than the height of the screw portion 92 of the screw.
As a result, the screw 89 can be inserted from the front side of the connecting portion 90 with the screw portion 92 facing the rear side. The screw 89 is inserted so that the head 91 of the screw 89 fits in the recess of the connecting portion 90 and the screw portion 92 penetrates the through hole 94.
The connecting portion 90 is formed of a metal material such as iron. Of course, the material of the connecting portion 90 is not limited, and any material may be used.
Further, each surface of the unit substrate connecting plate 88 is formed as a machined surface precisely machined by machining.

The unit board 10 is configured with a connecting plate mounting hole 95. The connecting plate mounting hole 95 is a hole for mounting the unit board connecting plate 88.
For example, the connecting plate mounting hole 95 is configured on the side of the unit substrate 10. In the example shown in FIGS. 22 and 23, two connecting plate mounting holes 95 are configured above the right side of the unit substrate 10 on the left side. Further, two connecting plate mounting holes 95 are configured above the left side of the unit substrate 10 on the right side. The unit board connecting plate 88 is mounted to each of the adjacent connecting board mounting holes 95 so as to straddle the left side and the right side unit boards.
Further, although the unit board connecting plate 88 is not attached in FIGS. 22 and 23, the connecting plate mounting holes 95 are also formed on the upper sides of the two unit boards 10. The connecting plate mounting hole 95 on the upper side is configured to connect the unit board 10 to the upper side of each unit board 10. In this way, the unit board 10 is provided with connecting plate mounting holes 95 on all four sides in order to connect the unit board 10 vertically and horizontally.

As shown in FIGS. 22 and 23, for example, the connecting plate mounting hole 95 is configured as a recess on the side of the unit substrate 10. Hereinafter, among the surfaces constituting the recess, the surface perpendicular to the Z direction may be expressed as the bottom surface of the recess, and the surface other than the bottom surface may be expressed as the side surface of the recess.
The connecting plate mounting hole 95 is formed as a machined surface in which each of the bottom surface and the side surface of the recess is precisely machined.

As shown in FIG. 23, when the unit boards 10 on the right side and the left side are arranged side by side, the connecting plate mounting holes 95 are adjacent to each other, and the bottom surface is rectangular on the two unit boards 10 arranged side by side. A recess is formed. In the present embodiment, the unit substrate connecting plate 88 is inserted into the recess formed when the unit substrates 10 are arranged side by side. As shown in FIG. 22, the unit substrate connecting plate 88 is inserted with a gap in the Y direction without a gap in the X direction.

As shown in FIG. 25B, a screw thread 96 is formed in the connecting plate mounting hole 95. The screw thread 96 is configured to fit the screw portion 92 of the screw 89 of the unit board connecting plate 88. The screw thread 96 is formed on the bottom surface of the recess of the connecting plate mounting hole 95 on the lower side of the center along the Y direction. Further, when the unit board connecting plate 88 is attached, the screw thread 96 is configured so that the positions of the through hole 94 of the connecting portion 90 and the screw thread 96 in the X direction and the Y direction are substantially equal to each other. ..
Of course, the screw thread 96 is formed in a shape that can be fitted with the screw portion 92.

FIG. 25A shows an enlarged view of the unit board connecting plate 88 as viewed from the display surface 53 side in a state where the unit board connecting plate 88 is mounted in the connecting plate mounting hole 95. As shown in FIG. 25A, the connecting portion 90 of the unit board connecting plate 88 is inserted into the lower portion of the connecting plate mounting hole 95, and two screws 89 are inserted into the connecting portion 90.
As shown in FIG. 25B, the screw portion 92 of the screw 89 is inserted into the through hole 94 of the connecting portion 90 and penetrates the connecting portion 90. The threaded portion 92 penetrating the connecting portion 90 is inserted into and fitted into the thread 96 of the extending connecting plate mounting hole 95.
In this way, the unit board connecting plate 88 is fixed to the two unit boards 10. As a result, the two unit boards 10 are connected to each other. Similarly, the unit substrate 10 can be connected in the vertical direction as well. Therefore, it is possible to connect a plurality of unit substrates 10 side by side in a two-dimensional grid pattern.

Further, each surface of the unit substrate connecting plate 88 and the bottom surface and side surfaces of the recesses of the connecting plate mounting hole 95 are formed as machined surfaces precisely machined. Therefore, when the unit boards 10 are connected, the heights of the respective unit boards 10 can be made uniform with high accuracy.
The unit substrate connecting plate 88 corresponds to one embodiment of the first connecting member according to the present technology, which connects two supporting members adjacent to each other having two display units adjacent to each other.

26A and 26B are views showing other configuration examples of the unit substrate connecting plate 88.
In the unit board connecting plate 88 shown in FIGS. 26A and 26B, the height of the unit board 10 when the unit board 10 is connected can be adjusted. This makes it possible to sufficiently suppress the difference in height of each unit substrate 10.

One of the two positioning member connecting plates 118 is connected so that the position along the Y direction is above the center of each side. The other is connected so that the position along the Y direction is lower than the center of each side.
In this way, the left and right positioning members 11 are fixed by the two positioning member connecting plates 118, and the respective positioning members 11 are connected.
Similarly, in the vertical direction, the positioning member 11 is connected by the two positioning member connecting plates 118.

FIG. 28 shows a perspective view of the vicinity of the connecting portion when the two positioning members 11 are connected in the left-right direction. Specifically, among the positioning members 11 connected to the left and right, the upper part of the right side of the positioning member 11 on the left side when viewed from the display surface side and the upper part of the left side of the positioning member 11 on the right side are centered. The perspective view of the part is shown.
That is, the portion of the positioning member 11 connected to the left and right, which is shown in FIG. 27, corresponding to the periphery of the positioning member connecting plate 118 on the upper side is shown in FIG. 28.
Note that FIG. 28 also shows an exploded perspective view of the positioning member connecting plate 118.
FIG. 29 shows an exploded perspective view of FIG. 28 when viewed from the rear side.

As shown in FIGS. 28 and 29, the positioning member connecting plate 118 has two screws 119 and a connecting portion 120.
The connecting portion 120 is configured in a flat plate shape. When viewed from the Z direction, the connecting portion 120 has a substantially rectangular shape. The connecting portion 120 includes two through holes 121 and two dowels 122.
The through hole 121 is a hole having a circular shape when viewed from the Z direction. The two through holes 121 are both configured on the right side of the connecting portion 120 when the connecting portion 120 is viewed from the front side.
The diameter of the through hole 121 is set to be larger than the diameter of the screw 119. That is, the screw 119 can penetrate the through hole 121.

The dowel 122 is configured as a cylindrical convex portion on the rear surface of the connecting portion 120.
As shown in FIG. 29, the two dowels 122 are both configured on the right side of the rear surface of the connecting portion 120 when the connecting portion 120 is viewed from the rear side. That is, when the connecting portion 120 is viewed from the front side, two dowels 122 are configured on the back side on the left side of the connecting portion 120.
The connecting portion 120 is formed of a metal material such as iron. Of course, the material of the connecting portion 120 is not limited, and any material may be used.
The two screws 119 have a head 123 and a screw portion 124.

In this embodiment, the sheet metal 125 is connected to the positioning member 11. The positioning member connecting plate 118 is connected to a position substantially equal to the position of the sheet metal 125 in the X direction and the Y direction.
The sheet metal 125 is configured in a flat plate shape. When viewed from the Z direction, the sheet metal 125 has a substantially rectangular shape. As shown in FIG. 28, for example, the sheet metal 125 is connected to the upper part on the right side of the positioning member 11 on the left side. Further, the sheet metal 125 is also connected to the upper part on the left side of the positioning member 11 on the right side.
The sheet metal 125 is made of a metal material such as aluminum. Of course, the material of the sheet metal 125 is not limited, and any material may be used. Further, the sheet metal 125 may be configured as the positioning member 11 by being integrally formed with the positioning member 11.

As shown in FIG. 28, each of the sheet metal 125 connected to each positioning member 11 is configured with two fitting holes. The sheet metal 125 connected to the positioning member 11 on the left side is configured with two dowel fitting holes 126. Further, the sheet metal 125 connected to the positioning member 11 on the right side is configured with two screw fitting holes 127.
The dowel fitting hole 126 is a hole for fitting with the dowel 122. The sheet metal 125 connected to the positioning member 11 on the left side is configured with two upper and lower dowel fitting holes 126.
The diameter of the dowel fitting hole 126 is set to be substantially equal to the diameter of the dowel 122. As a result, the dowel 122 is fitted with the dowel fitting hole 126 with almost no gap in the X direction and the Y direction.

The screw fitting hole 127 is a hole for fitting with the screw 119 included in the positioning member connecting plate 118. Similar to the dowel fitting hole 126, the two screw fitting holes 127 are also configured one above and one below the sheet metal 125 connected to the positioning member 11 on the right side.
The screw fitting hole 127 is configured with a screw thread so that it can be fitted with the screw 119 included in the positioning member connecting plate 118.

Further, as shown in FIG. 30, the positioning member 11 includes two dowel through holes 128 and two screw through holes 129.
The dowel through hole 128 is configured in the positioning member 11 on the left side so that the positions along the X direction and the Y direction are substantially equal to the dowel fitting hole 126 configured in the sheet metal 125. Further, the screw through hole 129 is configured in the positioning member 11 on the right side so that the positions along the X direction and the Y direction are substantially equal to the screw fitting hole 127 configured in the sheet metal 125. ..
The dowel through hole 128 is a hole through which the dowel 122 penetrates. The screw through hole 129 is a hole through which the screw 119 penetrates.

The positioning member connecting plate 118 is connected to the positioning member 11 in which the sheet metal 125 is connected.
Specifically, first, the dowel 122 configured in the connecting portion 120 of the positioning member connecting plate 118 is inserted into the dowel fitting hole 126 configured in the sheet metal 125 and fitted. The dowel 122 penetrates the sheet metal 125, and the tip end portion of the dowel 122 is inserted into the dowel through hole 128 of the positioning member 11.
Next, the screw 119 is inserted into the through hole 121 of the connecting portion 120 of the positioning member connecting plate 118. The screw 119 penetrates the connecting portion 120, and the screw portion 124 fits into the screw fitting hole 127 formed in the sheet metal 125. The screw 119 penetrates the sheet metal 125, and the tip end portion of the screw 119 is inserted into the screw through hole 129 of the positioning member 11.
In this way, the positioning member connecting plate 118 is connected to the positioning member 11. By fitting the dowel 122 and the screw 119, the positioning member connecting plate 118 is stably connected to the positioning member 11.
An assembly jig is used when the positioning member 11 is connected by the positioning member connecting plate 118. The functions of the assembly jig will be described later.

In the third connection step of step 103, the plurality of positioning members 11 thus connected are connected to the plurality of unit boards 10 connected in this way. Further, in step 104, the display module 9 is attached, and a large-sized display device 100 is configured.
In one display unit 5, eight display modules 9 and one positioning member 11 are configured to be integrally slidable with respect to one unit substrate 10. Similarly, the entire display module 9 and the entire positioning member 11 constituting the display device 100 are also configured to be integrally slidable with respect to the entire unit substrate 10.

When a plurality of unit boards 10 are connected, the plurality of unit boards 10 may be deformed due to their own weight. Even in such a case, the plurality of positioning members 11 slide and slide relative to the plurality of unit substrates 10. This makes it possible to suppress the influence of the stress generated by the deformation of the plurality of unit substrates 10 on the plurality of positioning members 11.
Therefore, for example, the number of vertically connected display units 5 can be significantly increased. This makes it possible to increase the screen size of the display device 100.
Further, since the influence of stress on the display panel 12 can be suppressed, it is possible to use glass having a low fracture stress as the material of the display panel 12. This improves the mass productivity of the display panel 12.
Even when the plurality of unit substrates 10 are deformed due to changes in temperature and humidity, it is possible to suppress the influence of stress on the plurality of positioning members 11 in the same manner.

Further, even if the plurality of unit boards 10 are deformed, the relative positional relationship between the display panels 12 is not affected. That is, the display modules 9 are attached so that the display panels 12 have gaps in the X direction and the Y direction, but the gaps between the display panels 12 are not eliminated in any case. Since an appropriate gap is always secured between the display panels 12, the display panels 12 can be reliably removed.

Further, the plurality of display modules 9 are positioned in the X direction and the Y direction with respect to the plurality of positioning members 11. That is, when installing the display module 9, it is not necessary to adjust the position of the display module 9. Therefore, the time required to install the display module 9 is shortened. In addition, the position accuracy of the display module 9 is improved.

The positioning member connecting plate 118 corresponds to one embodiment of the second connecting member according to the present technology, which connects two positioning members adjacent to each other having two display units adjacent to each other.

The positioning member connecting plate 118 may not have a dowel 122, and the positioning member connecting plate 118 may be connected to the positioning member 11 only by fitting with a screw 119. For example, when the positioning member 11 is connected in the left-right direction by such a positioning member connecting plate 118, the positioning member connecting plate 118 has two screws 119. One screw 119 fits into the screw fitting hole 127 of the sheet metal 125 configured in the positioning member 11 on the left side. Further, the other screw 119 fits into the screw fitting hole 127 of the sheet metal 125 configured in the positioning member 11 on the right side. As a result, each positioning member 11 and the positioning member connecting plate 118 are connected to each other.

Further, the positioning members 11 may be directly connected to each other without using the positioning member connecting plate 118. For example, the positioning member 11 may be connected by adhesion with an adhesive. In addition, the method of connecting the positioning members 11 to each other is not limited.

[How to connect the positioning member with an assembly jig]
When the positioning member 11 is connected by using the positioning member connecting plate 118, an assembly jig is used. A method of connecting the positioning member 11 using an assembly jig and a procedure for connecting the members 11 will be described.
In this embodiment, the positioning member 11 is configured with a jig hole 133. The jig hole 133 is a hole for fitting with the pin member of the assembly jig.

The assembly jig is used to fix the positioning member 11 when connecting the positioning member 11. The specific shape of the assembly jig is not limited, and any assembly jig designed so that the positioning member 11 can be connected may be adopted.
In this embodiment, the assembly jig has a pin member.

The positioning member 11 is configured with a jig hole 133.
As shown in FIG. 27, two jig holes 133 are configured for one positioning member 11.
One of the two jig holes 133 is configured in the vicinity of the leftmost partition rib portion 18 on the central rib portion 17 of the positioning member 11. The other is configured on the central rib portion 17 of the positioning member 11 in the vicinity of the partition rib portion 18 configured on the far right side.
The jig hole 133 is a hole having a circular shape when viewed from the Z direction. In the present embodiment, the jig hole 133 is a hole penetrating the positioning member 11, but the jig hole 133 may be a concave portion having a circular shape when viewed from the Z direction.
The diameter of the jig hole 133 is set to be substantially equal to the diameter of the pin member included in the assembly jig. That is, the jig hole 133 and the pin member are fitted to each other in the X direction and the Y direction without any gap.

In this embodiment, three different types of assembly jigs are used depending on the connecting direction of the positioning member 11. For example, when connecting the positioning members 11 in the left-right direction, the left-right jig 136 is used.
Further, when the positioning member 11 is connected in the vertical direction, the vertical jig 137 is used.
However, when the positioning member 11 is to be connected in the left-right direction and the positioning member 11 is already connected to the lower side of the newly connected positioning member 11, the positioning member 11 is connected in the left-right direction and the up-down direction. It is necessary to connect at the same time. In such a case, the combined jig 138 is used.

FIG. 32A is a schematic view showing the connection of the positioning member 11 by the left and right jig 136.
FIG. 32A shows a positioning member 11 arranged in the left-right direction, a jig hole 133, and a left-right jig 136. The two squares shown in FIG. 32A schematically represent the positioning member 11. Further, the rectangle schematically represents the left and right jig 136. The four points schematically represent the jig holes 133 configured in the respective positioning members 11.
The left and right jig 136 has four pin members. When the positioning members 11 are connected in the left-right direction, four pin members are fitted into the jig holes 133 configured in each of the positioning members 11. As a result, each positioning member 11 is fixed.
With the positioning member 11 fixed, the positioning member connecting plate 118 is connected. As a result, the positioning members 11 are connected in the left-right direction.

FIG. 32B is a schematic view showing the connection of the positioning member 11 by the vertical jig 137.
FIG. 32B shows a schematic diagram in which the positioning member 11 is connected in the left-right direction as in FIG. 32A, and then the positioning member 11 is connected to the upper side of the positioning member 11 on the right side.
The rectangle shown in FIG. 32B schematically represents the vertical jig 137. Similar to the connection by the left and right jig 136, the jig hole 133 and the pin member are fitted, and the positioning member 11 is connected in the vertical direction.

FIG. 32C is a schematic view showing the connection of the positioning member 11 by the combined jig 138.
In FIG. 32C, after the three positioning members 11 are connected as shown in FIG. 32B, the positioning member 146 is on the left side of the upper side positioning member 144 on the right side and on the upper side of the lower side positioning member 145 on the left side. A schematic diagram is shown when connecting the above.
The pentagon shown in FIG. 32C schematically represents the combined jig 138. In the connection by the combined jig 138, the pin member is fitted into the jig hole 133 on the left side of the positioning member 144 on the upper side on the right side. Further, the pin member is fitted into the jig hole 133, which is configured in each of the left upper positioning member 146 and the left lower positioning member 145. As a result, the positioning member 146 is connected.

By using the assembly jig, the positioning member connecting plate 118 is connected in a state where the positioning member 11 is fixed at a predetermined position. This makes it possible to connect a plurality of positioning members 11 with high accuracy. For example, it is possible to suppress deviations in the X direction and the Y direction of each of the positioning members 11 connected in a two-dimensional lattice pattern.
Since the deviation of each of the display modules 9 attached to the positioning member 11 in the X direction and the Y direction is also suppressed, it is possible to display a high quality image.

FIG. 31 is a schematic diagram showing the order of connection of the positioning members 11.
In this embodiment, the positioning members 11 are connected in the order of the arrows shown in FIG.
Each positioning member 11 is assembled in a state of being arranged on a plane, that is, a state in which the display surface 53 is arranged so as to be perpendicular to the direction of gravity.
Hereinafter, as shown in FIG. 31, the vertical unit of the positioning members 11 connected in a two-dimensional grid pattern may be expressed as a row and the horizontal unit may be expressed as a step.

First, one positioning member 11 is arranged. Hereinafter, the positioning member 11 arranged first will be referred to as a reference positioning member 141.

Hereinafter, as shown in FIG. 31, the row in which the reference positioning member 141 is arranged is referred to as the first row, the row to the right of the first row is referred to as the second row, and the row to the right of the second row is referred to as the third row. The column number is expressed for the right side of the first column. Further, the column number is expressed in the same manner for the left side of the first column, such that the column to the left of the first column is the second column and the column to the left of the second column is the third column. .. The overlapping column numbers on the right side and the left side may be expressed by clearly indicating the direction, such as the second column on the right side and the second column on the left side, if necessary. be.

Next, two or more positioning members 11 are connected along the left-right direction by using the left-right jig 136. That is, one or more positioning members 11 are connected to the reference positioning member 141 in the left-right direction.
The number of positioning members 11 connected is determined, for example, depending on the size of the display device 100. When the display device 100 is configured by the nine display units 5 as in the display device 100 shown in FIG. 2, three positioning members 11 are configured in the left-right direction. That is, two positioning members 11 are connected to the reference positioning member 141.
Further, for example, when it is desired to realize a large screen display device 100, a large number of positioning members 11 are connected in the left-right direction. In addition, the number of positioning members 11 connected in the left-right direction is not limited.

Next, using the vertical jig 137, two or more positioning members 11 are connected along the vertical direction.
In the present embodiment, one or more positioning members 11 are connected upward to the reference positioning member 141.
The number of positioning members 11 connected in the vertical direction is not limited.

Next, the positioning member 11 is connected using the combined jig 138.
In the present embodiment, the positioning member 11 is first connected to the second stage of the second row on the right side. Specifically, one positioning member 11 is simultaneously connected to the upper side of the first-stage positioning member 11 in the second row on the right side and the right side of the second-stage positioning member 11 in the first row. Will be done.
Next, for example, the positioning member 11 is connected to the second stage of the third row on the right side.
Next, for example, the positioning member 11 is connected to the third stage of the second row on the right side.
In this way, the positioning member 11 is repeatedly connected to the two positioning members 11 that are already connected so that one positioning member 11 is simultaneously connected.

Further, for example, after the positioning member 11 is connected to the second stage of the second row on the right side, the positioning member 11 may be connected to the third stage of the second row on the right side. The order in which the positioning member 11 is connected by using the combined jig 138 is not limited, and the step of connecting the positioning member 11 in the upper side and the left-right direction of the two already connected positioning members 11 is repeated arbitrarily. The connection method in the order of may be adopted.

In the examples shown in FIGS. 31 and 32, the left-right direction corresponds to one embodiment of the first direction according to the present technology. The vertical direction corresponds to one embodiment of the second direction orthogonal to the first direction according to the present technology.
The left and right jig 136 corresponds to an embodiment of the first jig for fixing two positioning members so as to be arranged adjacent to each other along the first direction according to the present technology.
The vertical jig 137 corresponds to an embodiment of a second jig for fixing two positioning members so as to be arranged adjacent to each other along a second direction according to the present technology.
The combined jig 138 fixes the second positioning member so as to be adjacent to the first positioning member along the first direction, and the second direction with respect to the first positioning member. It corresponds to one embodiment of the third jig for fixing the third positioning member so as to be arranged adjacent to each other along the above.
In the example shown in FIG. 32C, the positioning member 146 corresponds to the first positioning member, and the positioning member 144 corresponds to the second positioning member. Further, the positioning member 145 corresponds to the third positioning member.

The display module 9 has an adjustment mechanism 52, and the relative distance of the display panel 12 to the support board 51 can be adjusted. This makes it possible to display a high-quality image.

Further, in the display device 100 according to the present embodiment, the positioning member 11 that defines the position of each of the one or more display modules 9 with respect to the unit board 10 is slidably connected to the unit board 10. This makes it possible to display a high-quality image.
