Abstract:
An image display apparatus includes an image display element, and an eyepiece optical system configured to guide light from the image display element to an exit pupil. The eyepiece optical system includes at least one correction element having different characteristics between a central area and a peripheral area different from the central area. When first light is light emitted from a central portion of the image display element, and second light is light emitted from an outermost peripheral portion of the image display element, the characteristics of the at least one correction element are set such that color drift of the second light after pass through the peripheral area from the first light after pass through the central area is less than color drift of the second light before pass through the peripheral area from the first light before pass through the central area.
