Claim:
An image display apparatus comprising: a first display element configured to display a first original image; a second display element configured to display a second original image; and an optical system configured to present to an observer an enlarged combined image of the first and second original images with a first light flux from the first display element and a second light flux from the second display element, wherein the optical system includes at least one reflective surface, wherein, when a cross-section of the optical system on which optical paths of the first light flux and the second light flux are turned by reflections at the reflective surface is defined as a decentering cross-section, the first original image and the second original image correspond to different view angles from each other in the decentering cross-section, and wherein light flux components which are respectively included in the first light flux and the second light flux and introduced to a same image point in the enlarged combined image are overlapped with each other on an exit pupil plane of the optical system.
