Abstract
An image display device includes: a projection port that projects image display light generated based on an image signal; and a combiner that presents a virtual image by reflecting the image display light projected from the projection port. With respect to a specific direction along a reflection surface of the combiner, the curvature of the combiner in the specific direction becomes smaller as a distance from the projection port becomes larger. The reflection surface of the combiner may be formed by a biconic surface.
