PROBLEM TO BE SOLVED: To improve a light-blocking performance without obstructing visibility of virtual images by users.SOLUTION: A projection device 2 is the projection device 2 that projects an image in a viewing field of a user U as a virtual image, and comprises: a display device 20 that emits projection light of the image; a light reducing member 40 that reduces or blocks out a part of the projection light emitted from the display device 20 to thereby limit an optical path of the projection light; a driver 60 that causes the light reducing member 40 to be displaced in a direction going across the optical path of the projection light; and a controller 50 that allows the driver 60 to displace the light reducing member 40 on the basis of a position of an eye of the user U.SELECTED DRAWING: Figure 2

    【課題】外用者による虚像の視認を妨げずに遮光性能を向上する。【解決手段】投影装置2は、利用者Uの視野内に画像を虚像として投影する投影装置2であって、画像の投影光を射出する表示装置20と、表示装置20から射出された投影光の一部を減光又は遮光することにより、投影光の光路を制限する減光部材40と、減光部材40を投影光の光路に交差する方向に変位させるドライバ60と、利用者Uの目の位置に基づいて、ドライバ60により減光部材40を変位させるコントローラ50と、を備える。【選択図】図2
