Next, the lower end of the display device 1 is gripped and rotated in the direction of arrow A shown in FIG.
Next, the lower end of the display device 1 is further rotated in the direction of arrow A shown in FIG. 10C, and the tilt stopper 35 is inserted into the opening 21d-1 of the bracket 21 lock claw 21d of the hook unit 20.
Finally, the grip of the lower end of the display device 1 is released, and the tilt stopper 35 is engaged with the engagement recess 21e (FIG. 11C).
The cable connection with the external device can be safely performed in a state where a sufficient gap is secured between the rear cover 3 and the wall 100 of the display device 1.

  In the wall hanging support device of this example, as shown in FIGS. 10 and 11, by changing the fixing position of the plate unit 30 and the hook unit 20 attached to the rear cover 3 of the display device 1, The tilt angle can be changed, and not only the display device 1 can be installed on the upper side of the wall 100 and the display screen 2 faces downward, but the display device 2 can be installed on the wall 100 near the floor and the display screen 2 can face upward. For example, by providing a slide rail in the vertical direction of the wall 100 and allowing the plate unit 30 to be slidably fixed thereon, it can be freely set according to the situation of the room used as the home theater and the viewing style at that time. You can also

  Further, the woofer unit 4 provided in the hook unit 20 attached to the rear cover 3 of the display device 1 efficiently reinforces the sound volume in the low frequency band, and the woofer unit 4 is opposed to the wall 100 in the vicinity. Therefore, the irradiated sound wave in the low frequency band is reflected by the wall 100 or vibrates the entire wall 100, and the tilt angle is changed, the direction of the reflected wave is changed, and the sound image is changed. It can be directly experienced by vibrations transmitted from the floor and the realism can be further improved.

According to the wall-mounted support device of the display device of this example, the tilt angle of the display screen 2 of the display device 1 can be changed and fixed in any direction up and down, and the woofer unit 4 that is integrally disposed facing the wall 100. Thus, it is possible to efficiently reinforce the volume of the bass frequency band with a simple configuration and to improve the sense of reality, and to be suitable for use in the display device 1 for home theater.
Further, the hook unit 20 provided with the woofer unit 4 is positioned and attached to the rear cover 3 of the display device 1 so that the connector 25a connected to the power supply wiring to the woofer unit 4 is connected to the corresponding speaker terminal of the display device 1. Since it is fitted, it can be handled easily without causing a connection leak or the like due to the external cable connection.

  Of course, the wall-hanging support device of the display device of the present invention is not limited to the above-described example, and various other configurations can be adopted without departing from the gist of the present invention.
