IMAGE DISPLAY DEVICE

An image display device includes: an image generation unit that generates image display light based on an image signal; a projection unit that projects the image display light generated by the image generation unit; a combiner (400) that presents the image display light projected by the projection unit as a virtual image; and a rotating unit (331) that rotationally moves the combiner along at least one rotation surface, wherein the projection unit changes a direction in which the image display light is projected based on the rotational movement of the combiner.
