Abstract

The present invention relates to a structure for installing a flat display device on an installation face. According to a conventional attaching structure, a complicated mechanism is required for a display unit and a fixing member thereof. Therefore, there has been a problem in that the weight and size of the whole device is increased. The flat display device according to the present invention comprises a display unit (1) having a projected portion (11) provided on a predetermined region of a rear face (1R) thereof, a body side fixing member (25) screwed to an upper face (113) of the projected portion (11), and an installation face side fixing member (26) screwed to an installation face (4). A projection (251) provided on an upper side end (25T1) of the body side fixing member (25) is inserted into a cut portion (261) provided on an upper side end (26T1) of the installation face side fixing member (26), and they are supported each other. Thus, the display unit (1) is installed on the installation face (4). Furthermore, the body side fixing member (25) and the installation face side fixing member (26) are fastened and fixed to each other with a screw (7) on both lower side end (25T2, 26T2) sides. The present invention is mainly applied to flat display devices for domestic and commercial use.
