ABSTRACT:
A retinal scanning image display apparatus includes a light source, a scanning unit that scans a light flux from the light source, a reflective surface that reflects the light flux from the scanning unit, and an ocular unit that guides the light flux from the reflective surface to an eye of an observer. Optical paths of the light flux scanned by the scanning unit intersect at an exit pupil position of the ocular unit, and the image display apparatus causes the scanning unit and the reflective surface to shift so that the optical paths of the scanned light flux toward the same image position are respectively moved in parallel to move the intersecting position of those optical paths. This realizes a small retinal scanning image display apparatus capable of keeping the image position substantially constant even when an observer moves their pupil.
