Image projection device

Abstract

An image projection device that can effectively curb an increase in temperature of an image projecting unit due to external light while maintaining quality of a projected image is provided. The image projection device includes an image projecting unit configured to emit projection light including an image, a first freeform curved mirror reflecting the projection light incident from the image projecting unit, an intermediate mirror reflecting the projection light incident from the first freeform curved mirror, and a second freeform curved mirror reflecting the projection light incident from the intermediate mirror and causing the projection light to reach a viewpoint. A component in at least one imaging axis direction of the projection light reflected by the first freeform curved mirror forms an image at an intermediate imaging position before the projection light reaches the second freeform curved mirror, and the intermediate mirror is arranged at the intermediate imaging position.
