Abstract
Provided is an image display device including an optical scanner configured to scan light emitted from a light source, a parallel light generator configured to generate the scanned light as parallel light, a prism configured to refract the parallel light, and a light direction changer including a plurality of points whereon the parallel light refracted by the prism is incident and configured to reflect or diffract the parallel light and change a traveling direction of the parallel light, wherein the prism is provided on a path of each light traveling from the optical scanner to the light direction changer to adjust an optical path difference of parallel light incident on each of the plurality of points of the light direction changer.
