The invention provides an image projection device and an information display device for a vehicle, which can restrain deterioration of an image display part caused by light from the outside. An image projection device (100) is provided with a projection optical unit (20) that projects light from a focal position (F), and an image display unit (10) that irradiates the projection optical unit (20) with light including image information, the image display unit (10) being disposed at a position farther from the projection optical unit (20) than the focal position (F). The image information is imaged as an aerial stereoscopic image (TI) at an imaging position between the focal position (F) and the projection optical unit (20).
本发明提供图像投影装置以及车辆用信息显示装置,能够抑制因来自外界的光而引起的图像显示部的劣化。图像投影装置(100)具备投影来自焦点位置(F)的光的投影光学部(20)、以及对投影光学部(20)照射包含图像信息的光的图像显示部(10),图像显示部(10)配置在比焦点位置(F)远离投影光学部(20)的位置,在焦点位置(F)与投影光学部(20)之间的成像位置将图像信息成像为空中立体像(TI)。
