Description

The present invention relates to a display device such as a liquid crystal television, for example. In particular, the present invention is inexpensive and can maintain a good appearance.

FIG. 5 and FIG. 6 show an example of a conventional display device, which is a liquid crystal display. FIG. 5 is a perspective view thereof, and FIG. 6 is a side view thereof.

As shown in FIGS. 5 and 6, a hinge 2 is fixed to the back surface of the thin display main body 1 having the liquid crystal module 1 </ b> A, and the lower end of the hinge 2 is attached to the stand 4 via the pivot shaft 3 in the front-rear direction a.
, B are pivotally supported so as to prevent the display body 1 from pivoting around the pivot shaft 3 by a pressing force of a spring (not shown). Reference numeral 5 denotes a rear cabinet.

In the above configuration, the opposing angle α from the front surface 1a of the display body 1 to the lower surface of the stand 4 is moved by moving the display body 1 forward a or backward b about the pivot shaft 3 against the pressing force of the spring.
