Description

  The present invention relates to a display unit that displays video, a display device that includes a holding body that holds the display unit, and a television receiver that includes the display device.

For example, a television receiver such as a liquid crystal television receiver (hereinafter referred to as a TV receiver) includes a display panel that displays an image on the front side, a display module that includes a backlight that emits light to the display panel, and a display module. A synthetic resin front cabinet and rear cabinet, which are housed so as to sandwich them, and a stand. The display module has a horizontally long and substantially rectangular parallelepiped shape as a whole, and is housed in the front cabinet and the rear cabinet in a vertical posture.
The backlight is disposed on the back side of the display panel, and includes an optical sheet, a light guide plate, and an LED substrate in a chassis.

As a TV receiver installation method, there are a method in which a display module is supported by a stand and a wall hanging method. For example, in North America and the like, approximately 50% of TV receivers are installed by the wall hanging method.
The TV receiver is provided with four fixtures having a screw cylinder in which a female screw conforming to the VESA (Video Electronics Standard Association) standard is provided on the rear surface of the chassis. The screws are attached to the wall side fixture and the rear cabinet. It is often fixed to the wall by being inserted into the screw insertion hole and screwed into the female screw of the fixture.

  Patent Document 1 discloses a display device having a wall-hanging plate that can restrict the movement of the screw cylinder and prevent the screw cylinder from being pulled out even when the wall-hanging screw cylinder may be moved by an external force. The invention is disclosed. Specifically, the wall-hanging plate body has a substantially strip shape, and is bent from the second hole separated from the first hole and the edge of the second hole at four locations separated in the longitudinal direction and the width direction. A projecting piece is provided, and the tip of the projecting piece is bent to the first hole side to form a blocking piece, and a hook portion of a screw cylinder having a female screw is locked to the first hole, and the blocking piece is attached to the hook portion. To prevent the screw tube from being pulled out from the one end side. The structure of Patent Document 1 is complicated and has a caulking process, so that there is a problem that manufacture is complicated.

Unlike the structure in which a screw cylinder is provided on a wall-hanging plate body and the wall-hanging plate body is screwed to the chassis as in the display device of Patent Document 1, in recent years, the screw cylinder is formed on the upper surface of a pedestal having a square hook shape, for example. More often, the pedestal is screwed to the chassis or the reinforcing bracket.
In this case, the screw that holds the fixture to the chassis or the reinforcing bracket may be loosened and come off due to vibration or aging. If the screw is removed when the wall is hung, the fixture may come off from the chassis or the reinforcing bracket, which immediately causes the TV receiver to fall off, which is dangerous.
Accordingly, there is a demand for a structure in which the fixing tool cannot be easily removed even when the screw for fixing the fixing tool to the chassis or the reinforcing metal comes off.
