Description

[Technical Field]

[0001] The present disclosure relates to a display device including a stand that is attached to the rear surface of a display panel. [Background technology]

[0002] Display devices such as television receivers and personal computers have a display (panel) for displaying images, and the rear side of the display is covered with a cover or the like. In recent years, there has been a strong demand for thinner display devices, and efforts have been made to reduce the thickness of covers and the like. However, with display devices, it is also important to be able to be stably installed on a desk or the like, and efforts have been made to ensure rigidity while reducing the thickness in order to ensure a stable installation state (see, for example, Patent Document 1).

[0010] (First embodiment) Hereinafter, a display device according to a first embodiment of the present disclosure will be described with reference to the drawings.

[0011] Fig. 1 is an exterior side view showing a display device according to a first embodiment of the present disclosure, and Fig. 2 is an exterior perspective view showing the display device according to the first embodiment of the present disclosure. Note that Fig. 2 shows a state in which a surface fixing part 40 attached to a wall surface (an example of an installation surface) of the stand part has been removed in consideration of ease of viewing the drawing.

[0012] A display device 1 according to a first embodiment of the present disclosure includes a display panel 10 on which an image is displayed on a display surface 11, and a stand attached to a rear surface 12 of the display panel 10. In this embodiment, the stand includes a surface fixing portion 40 fixed to an installation surface, a rotation portion 30 that is rotatable relative to the surface fixing portion 40, and a support portion 20 connected to the rotation portion 30 and that supports the display panel 10.

[0013] The display panel 10 has a horizontally elongated, generally rectangular shape and includes a display formed of liquid crystal or the like, and a rear cover that protects the outer periphery and rear surface of the display. 1 and 2 show a state in which the display panel 10 is attached to a stand with its longitudinal direction aligned with the left-right direction (horizontal installation), but this is not limiting, and as will be described later, the display panel 10 may also be attached to a stand with its longitudinal direction aligned with the up-down direction (portrait installation).

[0014] 1 and 2, the support part 20 is attached so as to engage with the rear engagement part 13 provided on the lower part of the rear surface of the display panel 10, and the pivot part 30 is attached to the upper end of the support part 20. Although FIGS. 1 and 2 show a state in which the stand part is attached to the display panel 10 with the pivot part 30 oriented to be located above the support part 20 (upward support), this is not limiting, and as will be described later, the stand part may also be attached to the display panel 10 with the pivot part 30 oriented to be located below the support part 20 (downward support).

[0015] The surface fixing unit 40 is fixed to the rotating unit 30 or the installation surface using, for example, screws or the like. Note that the method of attaching the surface fixing unit 40 and the rotating unit 30 is not limited to this, and a combination of holes and claws or a combination of stepped pins and slits may also be used, as long as they are structured to hold each other so that they do not come off even when a weak force is applied. While FIGS. 1 and 2 show the surface fixing unit 40 attached to a wall, this is not limiting, and the surface fixing unit 40 may also be placed and fixed on the upper surface of a floor, stand, or the like. As long as the surface fixing unit 40 is placed on the floor or the like so that it does not easily move using its own weight or friction, it is not necessary to fix the surface fixing unit 40 to the floor using screws or the like.

[0016] Fig. 3 is an enlarged perspective view showing the vicinity of the rear engagement portion. In Fig. 3, for ease of viewing, only the components of the display panel 10 that correspond to the rear engagement portion 13 are extracted and shown, and other components are omitted.

[0017] The rear engaging portion 13 is a part of the housing constituting the rear cover described above, and has an engaging hole 13a into which an engaging portion 22 (see FIG. 4 described later) provided on the support portion 20 is inserted. The opening of the engaging hole 13a faces downward, and the engaging portion 22 is inserted from below to above the engaging hole 13a. Note that instead of providing the engaging hole 13a, the rear engaging portion 13 may be provided with a recess that matches the shape of the engaging portion 22, or the engaging portion 22 may be fitted into the recess and hooked onto the recess, thereby locking them together.

[0018] In this embodiment, the support part 20 is provided with two engagement parts 22 at laterally symmetrical positions, and accordingly, two engagement holes 13a are provided in the back engagement part 13. The two engagement holes 13a are provided at positions spaced apart on the left and right, but this is not limitative, and the number and positions of the engagement holes 13a may be adjusted depending on the support part 20 and the engagement parts 22.

[0019] Below engagement hole 13a, rear recess 13b is provided which is recessed more toward display surface 11 than the surrounding area. Rear recess 13b is shaped to fit engagement portion 22, and when engagement portion 22 is inserted into engagement hole 13a, engagement portion 22 fits into the recessed space in rear recess 13b, so engagement portion 22 does not come into contact with the housing and hinders insertion into engagement hole 13a.

[0020] The rear engaging portion 13 is provided with rear screw holes 13c for screwing to the support portion 20. The number and positions of the rear screw holes 13c can be designed according to the support portion 20, and they only need to be located at positions that overlap with screw holes (flat screw holes 21a described later) provided in the support portion 20 when the engaging portion 22 is engaged with the rear engaging portion 13.

[0021] Fig. 4 is a perspective view showing the support part and the rotating part, and Fig. 5 is a side view showing the support part and the rotating part. Figs. 4 and 5 show a state in which the rotating part 30 is oriented to be located below the support part 20 (facing downward).

[0022] The support part 20 has a flat plate part 21 that contacts the back surface 12 of the display panel 10, and a connecting part 23 that is connected to the flat plate part 21 and attached to the rotating part 30. Note that the support part 20 is formed by bending a shaped flat plate to form each part, and the flat plate part 21 and the connecting part 23 are fixed and connected with screws or the like.

[0023] The flat plate portion 21 has an engagement portion 22 formed by cutting out a portion thereof. The upper end of the engagement portion 22 has an upper end abutment portion 22a extending upward, and the lower end of the engagement portion 22 has a lower end abutment portion 22b extending downward. The upper end abutment portion 22a and the lower end abutment portion 22b are vertically symmetrical and correspond to the claws inserted into the engagement holes 13a described above. The flat plate portion 21 also has flat plate screw holes 21a for screwing to the rear engagement portion 13. The engagement portion 22 and the flat plate screw holes 21a are vertically symmetrical, and are positioned so that even if the flat plate portion 21 is turned upside down from the state shown in FIG. 4, the positions of the corresponding engagement portions 22 and flat plate screw holes 21a coincide. In other words, even if the flat plate portion 21 is turned upside down, the positions of the engagement portion 22 and flat plate screw holes 21a do not appear to change, and the engagement portion 22 and flat plate screw holes 21a remain in the same positions as before the inversion. As shown in Figures 4 and 5, when the support portion 20 is supporting downward, the upper end abutment portion 22a is inserted into the engagement hole 13a, and when the support portion 20 is supporting upward, as shown in Figures 1 and 2, the lower end abutment portion 22b is inserted into the engagement hole 13a.

[0024] The rotating unit 30 has a base 31 supported by the surface fixing unit 40 and a rotating plate 32 rotatably attached to the base 31. An end (connecting end 24) of the connecting unit 23 is fixed to the rotating plate 32, and when the rotating plate 32 rotates, the support unit 20 rotates accordingly (in the direction of arrow R). In the state shown in FIGS. 4 and 5 , the rotation axis of the rotating unit 30 extends in the vertical direction, and the rotating plate 32 rotates around that axis. In this embodiment, the surface of the flat plate unit 21 that contacts the back surface 12 of the display panel 10 is parallel to the rotation axis of the rotating unit 30. Therefore, the rotating unit 30 rotates around an axis parallel to the back surface 12 of the display panel 10.

[0025] Fig. 6 is an enlarged perspective view showing the vicinity of the rear engagement part to which the support part and the rotating part are attached, and Fig. 7 is an enlarged front view showing the vicinity of the rear engagement part to which the support part and the rotating part are attached. Note that in Figs. 6 and 7, for ease of viewing, only the components of the display panel 10 that correspond to the rear engagement part 13 are extracted and shown, and other components are omitted.

[0026] 6 and 7 show a state in which the support portion 20 is supported upward as in FIGS. 1 and 2, with the lower end abutment portion 22b inserted into the engagement hole 13a. The surface of the flat plate portion 21 contacts the rear surface 12 (rear surface engagement portion 13) of the display panel 10 and is fixed to the rear surface engagement portion 13 with screws BS. As described above, the engagement portion 22 protrudes from the surface of the flat plate portion 21, but is accommodated in the rear surface recess 13b provided in the corresponding portion, and the flat plate portion 21 and the rear surface 12 can be brought into close contact with each other without being hindered by the engagement portion 22.

[0027] Next, the display device 1 installed on the floor or wall will be described with reference to FIGS. 8 to 10. FIG.

[0028] FIG. 8 is a schematic side view showing a display device installed on the floor.

[0029] 8, the support part 20 is attached to the display panel 10 in a downward facing state, and the rotating part 30 is located below the support part 20 and is supported by a surface fixing part 40 placed on the floor surface 101. In other words, the display device 1 is placed on the floor surface 101 via the surface fixing part 40.

[0030] The surface fixing unit 40 has a plate-like portion 41 facing the installation surface (floor surface 101 in FIG. 8 ) and a standing wall portion 42 supporting the rotating unit 30. The standing wall portion 42 is a flat plate along the side surface of the rotating unit 30 (particularly, the base 31) and is fixed to the rotating unit 30 with screws or the like. The standing wall portion 42 may be formed separately from the plate-like portion 41 and integrated with the plate-like portion 41 using a general method such as bonding or fixing. Note that the plate-like portion 41 and the standing wall portion 42 of the surface fixing unit 40 may be formed integrally as in a modified example shown in FIG. 23 , which will be described later.

[0031] FIG. 9 is a schematic side view showing a display device installed on a wall surface.

[0032] 9, similar to FIG. 8, the support unit 20 is attached to the display panel 10 in a downward supporting state, but differs in that the surface fixing unit 40 is installed on the wall surface 102. The surface fixing unit 40 may be attached to the wall surface 102 using a general method such as adhesion or fixing. As a result, the display device 1 is fixed to the wall surface 102 via the surface fixing unit 40.

[0033] In Figure 9, the support part 20 is attached to the display panel 10 in a state where it supports the display panel 10 facing downward, but this is not limited to this, and as described above, the support part 20 may be attached to the display panel 10 in a state where it supports the display panel 10 facing upward.

[0034] FIG. 10 is a schematic top view showing a display device installed on a wall surface.

[0035] In the display device 1 according to the present embodiment, the rotation unit 30 can be rotated even when the display device 1 is installed on a floor surface 101 or a wall surface 102. By rotating the rotation unit 30 (in the direction of arrow R), the end of the display panel 10 rotates so that it swings back and forth, thereby changing the orientation of the display panel 10. In this way, by rotating the rotation unit 30 with the stand fixed to the installation surface, the orientation of the display panel 10 can be changed to suit the user, thereby improving convenience.

[0036] The range (angle) of rotation of the rotation unit 30 may be appropriately restricted depending on the size of the display panel 10 and the distance from the wall surface 102 to the display panel 10. In other words, if the size of the display panel 10 increases or the distance from the wall surface 102 to the display panel 10 decreases, even if the angle at which the rotation unit 30 is rotated is small, the end of the display panel 10 will hit the wall surface 102 and the display panel will not be able to rotate any further.

[0037] As described above, the stand is attached to the rear surface 12 of the display panel 10 in either a first support state (for example, a state in which the support 20 faces downward) in a predetermined direction, or a second support state (for example, a state in which the stand is supported upward) in which the stand is rotated 180 degrees from the first support state. Therefore, the direction in which the stand is attached to the display panel 10 can be selected, improving the degree of freedom in installing the display device 1.

[0038] (Second embodiment) Next, a display device according to a second embodiment of the present disclosure will be described with reference to the drawings.

[0039] The second embodiment differs from the first embodiment in the configuration of the rear surface engaging portion 13. Since the second embodiment has substantially the same configuration as the first embodiment shown in Figures 1 to 10, a description thereof will be omitted and only the differences will be described.

[0040] FIG. 11 is a schematic plan view showing the rear surface of the display panel in the display device according to the second embodiment of the present disclosure.

[0041] 11 shows the rear surface 12 of the display panel 10, and of the support portion 20 attached to the display panel 10, only the flat plate portion 21 (particularly the engagement portion 22) is shown in perspective. The second embodiment differs from the first embodiment in that a plurality of rear surface engagement portions 13 are provided. In the example shown in FIG. 11, the rear surface engagement portions 13 are arranged in a line in the vertical direction, and are provided at the upper end, the center, and the lower end of the rear surface 12 of the display panel 10.

[0042] The rear surface 12 of the display panel 10 is provided with an extended recess 13d extending in the direction in which the rear surface engagement portions 13 are arranged (vertical direction). The extended recess 13d is connected to a rear surface recess 13b provided for the engagement hole 13a of each rear surface engagement portion 13. In other words, the rear surface 12 of the display panel 10 is provided with a vertically elongated recess in which the rear surface recess 13b and the extended recess 13d are integrated. The support portion 20 (particularly the engagement portion 22) is sized to fit into the extended recess 13d, and the position of the support portion 20 can be shifted with the engagement portion 22 fitted into the extended recess 13d. By shifting the support portion 20 while inserted into the extended recess 13d, the support portion 20 can be smoothly guided to the rear surface engagement portion 13 with which it is to be engaged.

[0043] In this embodiment, the support part 20 is designed so that its attachment position relative to the back surface 12 can be changed. FIG. 11 shows three states (first position P1 to third position P3) of the support part 20 whose position relative to the back surface 12 has been changed. Specifically, the first position P1 shows the support part 20 attached to the back surface engagement part 13 provided at the lower end. The support part 20 can be released from engagement with the back surface engagement part 13 by removing the engagement part 22 from the engagement hole 13a. The second position P2 shows the support part 20 being moved along the back surface recess 13b and the extended recess 13d. The third position P3 shows the support part 20 attached to the back surface engagement part 13 provided at the upper end.

[0044] When changing the mounting position of the support unit 20, the display panel 10 and the support unit 20 can be shifted relative to each other. The support unit 20 can be moved relative to the fixed display panel 10, or the display panel 10 can be moved with the support unit 20 fixed. In other words, when the stand unit is mounted on the installation surface, the display panel 10 can be lifted to disengage from the engagement unit 22, and the display panel 10 can be moved so as to align with the desired rear engagement unit 13. In this way, by providing multiple rear engagement units 13, the user can freely set the mounting position of the stand unit relative to the display panel 10. Furthermore, because the rear engagement units 13 are aligned in one direction, the relative positions of the multiple rear engagement units 13 can be easily grasped.

[0045] FIG. 12 is a schematic side view showing a display device installed on a wall surface.

[0046] 12 shows the third position shown in FIG. 11 , where the support unit 20 is attached to the upper end of the display panel 10 and supports the display panel 10 facing downward. In the state shown in FIG. 12 , the upper end of the stand is lower than the upper end of the display panel 10, and when viewed from the display surface 11 side of the display panel 10, the stand is hidden by the display panel 10, improving the appearance quality. However, the present invention is not limited to this, and the stand can be installed so that it is hidden by the display panel 10 by appropriately adjusting the position at which the stand is attached to the display panel 10 and the orientation of the support unit 20.

[0047] (Third embodiment) Next, a display device according to a third embodiment of the present disclosure will be described with reference to the drawings.

[0048] The third embodiment differs from the second embodiment in the arrangement of the rear surface engaging portion 13. Since the third embodiment has substantially the same configuration as the first and second embodiments shown in Figures 1 to 12, a description thereof will be omitted and only the differences will be described.

[0049] FIG. 13 is a schematic plan view showing the rear surface of the display panel in the display device according to the third embodiment of the present disclosure.

[0050] 13, like FIG. 11, shows the rear surface 12 of the display panel 10, and perspectively shows only the flat plate portion 21 (particularly the engagement portion 22) of the support portion 20 attached to the display panel 10. The third embodiment differs from the second embodiment in the direction in which the rear surface engagement portions 13 are arranged. In the example shown in FIG. 13, the rear surface engagement portions 13 are arranged in the left-right direction, and are provided at the left end, center, and right end when the display panel 10 is viewed from the rear surface 12 side.

[0051] In this embodiment, the extended recess 13d extends in the left-right direction and is connected to the rear recess 13b provided for the engagement hole 13a in each rear engagement portion 13. In other words, the rear surface 12 of the display panel 10 is provided with a horizontally elongated recess in which the rear recess 13b and the extended recess 13d are integrated.

[0052] This embodiment is also designed so that the position at which the support part 20 is attached can be changed relative to the back surface 12, and Fig. 13 shows two states (fourth position P4 and fifth position P5) of the support part 20 whose position relative to the back surface 12 has been changed. Specifically, the fourth position P4 shows the support part 20 attached to the back surface engagement part 13 at the left end, and the fifth position P5 shows the support part 20 being moved along the back surface recess 13b and the extended recess 13d.

[0053] FIG. 14 is a schematic side view showing a display device installed on a wall surface.

[0054] 14 shows the fourth position shown in FIG. 13 , where the support member 20 is attached to the left end (the right end in FIG. 14 ) of the back surface 12 of the display panel 10. When the support member 20 is attached to the left-right end of the display panel 10 in this way, the end closer to the support member 20 can be rotated only a small distance, making it less likely to hit the wall surface 102. Therefore, the end farther from the support member 20 can be rotated significantly (in the direction of arrow R) so as to be farther away from the wall surface 102.

[0055] (Fourth embodiment) Next, a display device according to a fourth embodiment of the present disclosure will be described with reference to the drawings.

[0056] The fourth embodiment differs from the first embodiment in the structures of the support portion 20 and the rotating portion 30. Note that, for the fourth embodiment, descriptions of matters that are substantially the same as those of the first to third embodiments shown in Figures 1 to 14 will be omitted, and only the differences will be described.

[0057] FIG. 15 is a schematic side view illustrating a state in which the display device according to the fourth embodiment of the present disclosure is installed on a floor surface.

[0058] The support unit 20 in the fourth embodiment does not include the flat plate unit 21, but instead includes a fixed shaft unit 25 that is connected to the rotation axis of the rotating unit 30 so as to extend therefrom. The structures of the support unit 20 and the rotating unit 30 will be described later with reference to Figures 18 to 22. In the state shown in Figure 15, the surface fixing unit 40 is placed on the floor surface 101, and the rotating unit 30 is fixed to the standing wall unit 42 of the surface fixing unit 40.

[0059] The fixed shaft portion 25 extends upward from the upper surface of the rotating portion 30, and its tip portion along the back surface 12 of the display panel 10 is fixed to the back surface engagement portion 13 with a screw or the like. The back surface engagement portion 13 may be provided with a hole or recess into which the fixed shaft portion 25 is inserted. The fixed shaft portion 25 rotates together with the rotation axis of the rotating portion 30, and the display panel 10 fixed to the fixed shaft portion 25 also rotates together. In the state shown in FIG. 15 , by rotating the fixed shaft portion 25 together with the rotating portion 30, the display panel 10 rotates so that its end portions in the left-right direction swing back and forth, similar to the state shown in FIG. 10 .

[0060] FIG. 16 is a schematic side view illustrating a state in which a display device according to a fourth embodiment of the present disclosure is installed on a wall surface.

[0061] In this embodiment, as in the first embodiment, the display device 1 can be installed on a wall surface 102 via a stand. The rotating unit 30 is attached to the wall surface 102 via a surface fixing unit 40, and a rotation axis is provided so that the display device 1 can rotate around an axis perpendicular to the rear surface 12 of the display panel 10. The fixed shaft 25 extends from the surface of the rotating unit 30 that faces the rear surface 12 of the display panel 10, and its tip is adapted to be inserted into the rear surface engagement unit 13. As in FIG. 15 , the rear surface engagement unit 13 is provided with a hole or recess into which the fixed shaft 25 is inserted, and the fixed shaft 25 can be fixed to the rear surface engagement unit 13 with a screw or the like.

[0062] FIG. 17 is a schematic front view showing a display device installed on a wall surface as viewed from the display surface side.

[0063] As shown in Fig. 16, when the support unit 20 is attached so that the rotation axis of the rotation unit 30 is perpendicular to the rear surface 12 of the display panel 10, the display panel 10 itself can be rotated relative to the horizontal direction to change its orientation. That is, when viewed from the display surface 11 side, the display panel 10 rotates with the fixed shaft unit 25 as a fulcrum so that the end portion describes an arc-shaped trajectory. As a result, when the display panel 10 is installed horizontally relative to the stand unit (as shown by the solid line in Fig. 17) on the wall surface 102, rotating the rotation unit 30 (in the direction of arrow S) changes the orientation of the display panel 10 so that it is installed vertically relative to the stand unit (as shown by the two-dot chain line in Fig. 17).

[0064] Next, the support unit 20 and the rotating unit 30 in the display device 1 according to the fourth embodiment of the present disclosure will be described with reference to Fig. 18 to Fig. 22. Note that in Fig. 18 to Fig. 22, hatching of cross sections of each member is omitted in consideration of ease of viewing the drawings.

[0065] FIG. 18 is a schematic cross-sectional view showing the support portion and the rotating portion, and FIG. 19 is a schematic top view showing the support portion and the rotating portion.

[0066] In this embodiment, the fixed shaft portion 25 is inserted into a hole provided in the center of one of the faces (the upper bearing face 33 in FIG. 18) of the rotating portion 30. The bearing face 33 is also provided with a face fixing hole 33a into which a fixing pin 50, which will be described later, is inserted.

[0067] A disk 34 is housed inside the rotating unit 30 and is rotatably supported parallel to the support surface 33. The disk 34 has a hole that overlaps with the hole in the support surface 33 when viewed from above, and the fixed shaft 25 is inserted through the hole. That is, the fixed shaft 25 is inserted through both the support surface 33 and the disk 34. Although the fixed shaft 25 is inserted through the support surface 33 and the disk 34, it is not fixed to either and is allowed to rotate freely. Similarly to the support surface 33, the disk 34 has a disk fixing hole 34c into which a fixing pin 50 (described later) is inserted. By rotating the disk 34, the disk fixing hole 34c can be moved to directly below the surface fixing hole 33a.

[0068] The support part 20 is located inside the rotating part 30, and has a shaft extension part 27 extending from the lower end of the fixed shaft part 25, and the tip of the shaft extension part 27 is connected to the shaft locking part 26. The shaft locking part 26 extends upward and has a length that reaches the disc 34.

[0069] The disk 34 is provided with a first locking hole 34a and a second locking hole 34b into which the shaft locking portion 26 is inserted. Figures 18 and 19 show a state in which the shaft locking portion 26 is inserted into the first locking hole 34a, and a state in which the shaft locking portion 26 is inserted into the second locking hole 34b and the positional relationship between the first locking hole 34a and the second locking hole 34b will be explained below in conjunction with Figures 20 to 22.

[0070] A locking member 28 is attached to the upper end of the shaft locking portion 26. The locking member 28 is located above the disk 34 and is larger than the first locking hole 34a and the second locking hole 34b. In other words, when the locking member 28 is attached while the shaft locking portion 26 is inserted into the first locking hole 34a or the second locking hole 34b, the locking member 28 is caught and the shaft locking portion 26 cannot be removed from the first locking hole 34a or the second locking hole 34b. When the shaft locking portion 26 is locked into the first locking hole 34a or the second locking hole 34b, rotating the fixed shaft portion 25 rotates the disk 34. As shown in FIG. 15 , when the display device 1 is installed on a floor surface 101, rotating the fixed shaft portion 25 changes the orientation of the display panel 10.

[0071] FIG. 20 is a schematic cross-sectional view showing the support portion and the rotating portion during rotation of the rotating shaft portion.

[0072] Next, the procedure for transitioning from a state in which the shaft locking portion 26 is inserted into the first locking hole 34a to a state in which the shaft locking portion 26 is inserted into the second locking hole 34b will be described. First, the fixing pin 50 is inserted so that it passes through both the surface fixing hole 33a and the disk fixing hole 34c. Once the fixing pin 50 is inserted, the disk 34 will no longer rotate. Next, the locking member 28 is removed, and the fixed shaft portion 25 is pushed downward. When the fixed shaft portion 25 is pushed in, the shaft extension portion 27 and the shaft locking portion 26 also move downward, and the shaft locking portion 26 is released from the first locking hole 34a. As a result, because the shaft locking portion 26 is not inserted into the first locking hole 34a, the disk 34 will not rotate, but the fixed shaft portion 25 will rotate.

[0073] 21 is a schematic cross-sectional view showing the support section and the rotating section when the rotating shaft section is rotated, and FIG. 22 is a schematic top view showing the support section and the rotating section in the state shown in FIG.

[0074] After rotating the fixed shaft portion 25 until the shaft locking portion 26 is positioned directly below the second locking hole 34b, the fixed shaft portion 25 is pulled upward, and the shaft locking portion 26 is inserted into the second locking hole 34b. Thereafter, the locking member 28 is attached to prevent the shaft locking portion 26 from coming out of the second locking hole 34b.

[0075] 22, the first locking hole 34a and the second locking hole 34b are arranged so that the shaft locking portion 26 moves back and forth between directly below each other when the fixed shaft portion 25 is rotated 90 degrees. By rotating the fixed shaft portion 25 90 degrees and keeping the shaft locking portion 26 locked in either the first locking hole 34a or the second locking hole 34b, the display panel 10 can be switched between a landscape orientation and a portrait orientation, as shown in FIG.

[0076] Next, a modified example of the surface fixing portion 40 in the display device 1 will be described with reference to FIG.

[0077] FIG. 23 is a schematic perspective view showing a modified example of the surface fixing portion.

[0078] In this modified example, the standing wall portion 42 is formed by cutting and raising a portion of the plate-shaped portion 41. In other words, the surface fixing portion 40 is formed from a plate member in which the plate-shaped portion 41 and the standing wall portion 42 are integrated, and the standing wall portion 42 is formed by cutting and bending the plate-shaped portion 40. The standing wall portion 42 may be provided with screw holes, claws, slits, and the like as structural portions for holding the rotating portion 30. Similarly, the plate-shaped portion 41 may also be provided with structural portions for attachment to the installation surface. In this way, by integrally forming the plate-shaped portion 41, which is attached to the installation surface, and the standing wall portion 42, which holds the rotating portion 30, the number of parts can be reduced, thereby reducing costs and the effort required for installation.

[0079] It should be noted that the embodiments disclosed herein are illustrative in all respects and are not intended to be limiting. Therefore, the technical scope of the present disclosure should not be interpreted solely by the above-described embodiments, but should be defined based on the claims. Furthermore, all modifications within the scope and meaning equivalent to the claims are included. [Explanation of symbols]
