To prevent external light from degrading visibility of an image viewed by a user.SOLUTION: An image projection device provided herein is configured to project an image formed on an image forming member 15 onto a projection surface by means of a projection optical system 511. An image light exit surface of the image forming member is tilted with respect to an optical axis L0 of image light such that, when external light L' entering the projection optical system is incident on the image light exit surface of the image forming member, rays traveling along an optical axis of the external light reflected by the image light exit surface are directed toward outside an eye range 402a of a user.SELECTED DRAWING: Figure 13

    【課題】外光によってユーザーに視認される画像の視認性が低下するのを抑制することを課題とする。【解決手段】画像形成部材15上に形成される画像を投写光学系511によって投写する画像投写装置であって、前記画像形成部材の画像光出射面は、前記投写光学系へ入射する外光L’が該画像形成部材の画像光出射面に入射したときに該画像光出射面で反射した外光の光軸に沿って進む光束がユーザーの視点領域402aから外れるように、画像光の光軸L0に対して傾斜して配置されていることを特徴とする。【選択図】図13
