<p>A head mount display comprises display means for displaying an image for a wearer, support means for supporting the display means, and installation means for supporting the supporting means and installing the support means at a position off the wearer's face. The support means is constructed so as to be horizontally or substantially horizontally movable from a position where the display means is in front of the wearer's eyes to the backside of the head. Thus the display device is relatively less view-obstructive for the wearer.</p>
