Summary:PROBLEM TO BE SOLVED: To provide a downsized spatial image display device that can display a spatial image with a plurality of depths.SOLUTION: A spatial image display device 1 comprises: a casing 11; one or more transmittance variable plates 13 that are arranged outside the casing 11, project projection light from a projector 20 and variably control transmittance; and an optical element 12 that is arranged inside the casing 11, enters light projected to the transmittance variable plates 13, and causes a spatial image to be formed inside the casing 11. A position of the spatial image is controlled by controlling the transmittance of the transmittance variable plates 13.SELECTED DRAWING: Figure 1 【課題】複数の奥行きを有する空間像を表示することが可能な小型の空間像表示装置を提供する。【解決手段】空間像表示装置１は、筐体１１と、筐体１１の外部に配置され、プロジェクタ２０からの投射光を投影する、透過率を可変に制御可能な１枚以上の透過率可変板１３と、筐体１１の内部に配置され、透過率可変板１３に投影されている光を入射し、筐体１１の内部に空間像を形成させる光学素子１２と、を備え、空間像の位置は、透過率可変板１３の透過率を制御することで制御されることを特徴とする。【選択図】図１
