description	To display an aerial image with high visibility.SOLUTION: A display device 1 includes a display panel 20 including a display surface 21 for displaying a display image 3, an imaging optical element 30 with a light incidence surface 31 and a light emission surface 32, an acquisition unit 61 that acquires a photographic image including a user 2 who is photographed, a detection unit 62 that determines at least one of the line of sight of the user 2 and the direction of the face of the user 2 from the photographic image and detects an attention region 5 to which the user pays attention, and a control unit 63 that controls an inclination angle θ of the display surface 21 with respect to the light incidence surface 31. The imaging optical element 30 receives light from the display image 3 displayed on the display surface 21 at the light incidence surface 31 and emits the light from the light emission surface 32, so that an aerial image 4, which is a projection image of the display image, is imaged at a position apart from the light emission surface 32. The control unit 63 controls the inclination angle θ so that the aerial image 4 is imaged in the attention region 5.SELECTED DRAWING: Figure 1 【課題】視認性の高い空中像を表示する。【解決手段】表示装置１は、表示画像３を表示する表示面２１を有する表示パネル２０と、光入射面３１及び光出射面３２を有する結像光学素子３０と、撮影されたユーザ２が映る撮影画像を取得する取得部６１と、撮影画像からユーザ２の視線及びユーザ２の顔の向きの少なくとも一方を判別して、ユーザが注目する注目領域５を検出する検出部６２と、光入射面３１に対する表示面２１の傾斜角θを制御する制御部６３と、を備える。結像光学素子３０は、表示面２１に表示された表示画像３からの光を光入射面３１で受け、光出射面３２から出射させることで、表示画像の投影像である空中像４を光出射面３２から離れた位置に結像させる。制御部６３は、注目領域５に空中像４が結像するように傾斜角θを制御する。【選択図】図１
