Description

  The present invention relates to a display device, and more particularly to a support structure for a display unit.

  As a conventional technique, there is known a liquid crystal display device in which an apparatus main body is supported by a supporting leg near its center of gravity and attached to a pedestal (for example, see Patent Document 1).

This liquid crystal display device has a structure in which a liquid crystal module is supported by a support leg raised from a pedestal so that tilt adjustment is possible. According to this configuration, the distance between the center of gravity of the device body and the mounting position of the support leg on the device body side is shorter than when the support legs are attached to the back of the cabinet covering the liquid crystal module, and the device body is supported stably. can do. Moreover, the front-rear width of the pedestal can be shortened.
