When the connecting piece 84a of the movable body 83a and the burrings 78 and 79 provided on the back surface 71 side of the support plate 70 come into contact with each other, the position of the support plate 70 with respect to the movable body 83a is defined. Further, as shown in FIG. 8B, the two burrings 78 are provided so as to be aligned in the horizontal direction. A burring 79 is provided slightly below the two burrings 78. The connecting piece 84 a is provided with a notch 89 a that engages with the burring 79. The notch 89a is on the recess. When the two burrings 78 and the movable body 83a abut, the position of the support plate 70 in the vertical direction with respect to the movable body 83a is defined. Moreover, the position in the left-right direction of the support plate 70 with respect to the movable body 83a is prescribed | regulated by the burring 79 and the notch part 89a engaging. Thereby, the position of the support plate 70 with respect to the movable body 83a can be accurately defined. Thereby, it can prevent that the display apparatus main body 30 is attached in the diagonal state with respect to the horizontal direction.

  As shown in FIG. 6, the burrings 78 and 79 are provided at positions sandwiched between two pairs of ribs 26. In other words, the two pairs of ribs 26 are provided at positions close to the burrings 78 and 79. The position in the left-right direction of the frame 20 with respect to the support plate 70 is defined at a position close to the burrings 78 and 79, which is a factor that determines the inclination of the support plate 70 with respect to the base 80. This is because the inclination of the frame 20 can be suppressed.

  In addition, as shown in FIG. 6, the engagement position between the convex portion 27 and the concave portion 77 a is also located below the burrings 78 and 79. This is because the inclination of the frame 20 can be suppressed by defining the vertical position of the frame 20 with respect to the support plate 70 at a position close to the burrings 78 and 79.

  FIG. 9 is a cross-sectional view of the display device 1. As shown in FIG. 9, a connecting component 50 is attached on the upper side.

The frame 20 is provided with a screw hole 29s at a position corresponding to the hole provided in the protruding piece 94. As shown in FIG. 10B, the holding component 90 has a substantially U-shaped cross section. Thereby, the distance D2 from the lower end surface of the display device main body 30 to the inner surface of the frame 20 can be shortened, and the frame 20 can be a narrow frame. For example, when the connecting component 50 or the holding component 90 has a substantially Z-shaped cross section, the thickness of the frame in the planar direction increases, and the frame cannot be narrowed.

11A, 11B, and 12A to 12C are explanatory views of the connecting component 50. FIG.
11A to 11B are perspective views of the connecting component 50. The connecting component 50 includes a base portion 51, a tongue portion 53 extending from the base portion 51 in a direction substantially perpendicular to the base portion 51, and an engaging portion 58 extending from the tongue portion 53.

The base portion 51 is located on the back side with respect to the support plate 70. The tongue 53 extends between the side surface of the display device main body 30 and the frame 20. By sliding the connecting component 50 in the releasing direction R along the long side of the support plate 70, the engaged state with the engaged portion 28 described later is released. When the connecting component 50 is assembled, the connecting component 50 is engaged with the engaged portion 28 by sliding the connecting component 50 in the engaging direction E. In the state shown in FIG. 12A, the engaged portion 28 and the connecting component 50 are engaged. The base portion 51 overlaps the back surface 71 of the support plate 70. Guide pins 72 are provided on the back surface 71. The guide pin 72 and the guide hole 52 have a function of guiding the slide of the connecting component 50.

  FIG. 12B is a cross-sectional view showing an engaged state between the engaging portion 58 and the engaged portion 28. In FIG. 12B, the left side is the front side of the display device 1. As shown in FIG. 12B, a plurality of engaged portions 28 are provided inside the frame 20 so as to correspond to the plurality of engaging portions 58. When the connecting component 50 is slid in the releasing direction R in this state, the engaging portion 58 is retracted from the engaged portion 28 and the engaged state is released. Thereby, the connection component 50 can be removed. Further, since the base portion 51 is located on the back surface 71 side of the support plate 70, the base portion 51 is fixed to the back surface 71 of the support plate 70 by the engagement between the engaged portion 28 and the engagement portion 58. The In this way, the connecting component 50 connects the frame 20 and the support plate 70.

  FIG. 12C is a cross-sectional view illustrating a state in which the back panel 60 is attached in a state where the frame 20 and the support plate 70 are coupled by the coupling component 50. As shown in FIG. 12C, a plurality of bosses 64 and a plurality of regulating pieces 65 are provided on the surface of the back panel 60 facing the support plate 70. When the rear panel 60 is attached, the boss 64 presses the connecting component 50 toward the support plate 70 side. Further, the regulation piece 65 abuts on the gripping piece 55 and regulates the sliding of the connecting component 50 in the release direction R. This prevents the engaged state between the engaged portion 28 and the engaging portion 58 from being released.

  When the connecting component 50 is attached or detached, the operator engages with the engaged portion 28 by grasping the gripping piece 55 of the connecting component 50 and sliding it in the releasing direction R with the back panel 60 removed. The engagement with the portion 58 can be released. Thus, the connecting component 50 can be easily removed.

The engagement between the engaging portion 58 and the engaged portion 28 will be described.
13A and 13B are explanatory diagrams of the engagement between the engaging portion 58 and the engaged portion 28. FIG. As shown in FIG. 13A, a notch portion 581 for facilitating engagement with the engaged portion 28 is provided at the tip of the engaging portion 58. The notch 581 is inclined with respect to the extending direction of the engaging portion 58. As shown in FIG. 13B, the engaging portion 58 is closer to the inside of the frame 20 than the tongue portion 53 due to the bent portion 583 at the boundary portion between the tongue portion 53 and the engaging portion 58. Thereby, engagement with the engaged portion 28 with the engaging portion 58 is ensured.

  As shown in FIG. 13A, the engaged portion 28 and the engaging portion 58 are engaged to define the position of the engaged portion 28 in the depth direction of the display device main body 30. As a result, the frame 20 is prevented from floating on the front side of the display device main body 30. Since the frame 20 is made of a synthetic resin, distortion may occur due to molding problems. If the frame 20 is distorted, a part of the frame 20 may be lifted from the display device main body 30. However, the engagement between the engaged portion 28 and the engaging portion 58 prevents such a part of the frame 20 from being lifted.

  Further, when the engaged portion 28 and the engaging portion 58 are engaged, a repulsive force of the frame 20 acts between the engaged portion 28 and the engaging portion 58. That is, the engaged portion 28 and the engaging portion 58 are engaged so that the frame 20 is forced along the edge of the display device main body 30. The reason why a repulsive force is generated in the frame 20 is that the frame 20 is made of synthetic resin and can be elastically deformed to some extent.

Next, maintenance inspection will be described.
