Image display apparatus and image capturing apparatus

The image display apparatus includes an optical system causing a light flux entering from an original image by being transmitted through a fifth surface to reflect at a fourth surface, a third surface, a first surface and a second surface and then cause the light flux to be transmitted through the first surface and exit toward an exit pupil, causing the light flux to form an intermediate image and causing optical paths to intersect with each other. The optical system satisfies 0.62≦L12/f≦5.00 and 1.80≦L45/L12≦5.00. When a distance between hit points of a central-view-angle principal ray on the surfaces is referred to as a hit point distance, L45 represents a hit point distance between the fourth and fifth surfaces, L12 represents a hit point distance between the first and second surfaces, and f represents a focal length of the optical system.
