Summary:PROBLEM TO BE SOLVED: To provide a small-size space display device capable of performing enlarged display or remote display.SOLUTION: A space display device 1 forms an image in an aerial region to display as an aerial image, and the device includes: a display 20 for displaying an image in a display screen 21; a convex lens 40; an imaging optical element 30 having an element surface 31, which forms an image of the image displayed on the display screen 21 into a region symmetric to the display screen 21 with respect to the element surface 31, assuming that the convex lens 40 is not present; a camera 70 for sensing a user; and a control part 80 for controlling at least either a position or a posture of at least one of the display screen 21, the convex lens 40 and the imaging optical element 30, in response to the user sensed by the camera 70. The convex lens 40 is disposed at a position between the display screen 21 and the imaging optical element 30, the position where a distance from the convex lens 40 to the display screen 21 is shorter than a focal distance of the convex lens 40.SELECTED DRAWING: Figure 6 【課題】拡大表示又は遠方表示が可能な小型の空間表示装置を提供する。【解決手段】画像を空中の表示領域に結像させて空中画像として表示する空間表示装置1であって、表示面21に画像を表示するディスプレイ20と、凸レンズ40と、素子面31を有する結像光学素子30であって、凸レンズ40が存在しないと仮定した場合に、表示面21に表示された画像を、素子面31に対して表示面21と面対称になる領域に結像させる結像光学素子30と、ユーザを検知するカメラ70と、カメラ70が検知したユーザに応じて、表示面21、凸レンズ40及び結像光学素子30の少なくとも1つの位置及び姿勢の少なくとも一方の調整を行う調整部80とを備え、凸レンズ40は、表示面21と結像光学素子30との間で、かつ、凸レンズ40から表示面21までの距離が凸レンズ40の焦点距離より短くなる位置に配置されている。【選択図】図6
