PROBLEM TO BE SOLVED: To provide a facemount display which has a long focal length. SOLUTION: In a headmount display, a plurality of 'small sets of lenses functioning as an optical telescope' is fitted side by side without any gap at a position of a window on which a video is projected or a position on which the video is projected in the opposite direction from normal peeping in the optical telescope and in a direction wherein a 'user of the headmount display' can peeps in the optical telescope composed of the set of lenses. At this time, the lenses of the 'set of lenses' are of proper sizes and in proper shapes for obtaining such an enlargement rate that the system can have a target focal length and at proper positions and angles so that a reverse optical telescope is put in focus on the position of the eye of the 'user'.
