Abstract:
1. An image display apparatus comprising: first and second display elements each configured to display an original image; and an observation optical system having a first optical unit including a first reflecting surface and configured to introduce light flux from the first display element to an exit pupil, and a second optical unit including a second reflecting surface and configured to introduce light flux from the second display element to the exit pupil, wherein the observation optical system is configured to present a combined image, wherein when a first decentering plane is defined as a plane including a light path before a principal ray of the light flux introduced to a prescribed point on the combined image by the first optical unit enters the first reflecting surface and a light path after the principal ray is reflected on the first reflecting surface, and a second decentering plane is defined as a plane including a light path before a principal ray of the light flux introduced to the prescribed point by the second optical unit enters the second reflecting surface and a light path after the principal ray is reflected on the second reflecting surface, the first decentering plane and the second decentering plane are parallel to each other, and wherein a part of a display surface of the first display elements and a part of a display surface of the second display element display the same image.
