Abstract

The image display apparatus includes an image capturing optical system, an image sensor, a display element, and an ocular optical system. An optical axis of the image capturing optical system and an optical axis of the ocular optical system are located on a same straight line. An image capturing view angle of the image capturing optical system is larger than a display view angle of the ocular optical system. The display element is configured to display, of an image generated by using a signal from the image sensor, an area corresponding to the display view angle. When d represents a distance between a position of an entrance pupil of the image capturing optical system and a position of the exit pupil of the ocular optical system, the condition of 20 mm≤d≤60 mm is satisfied.
