Abstract:
Provided is a display apparatus including an image forming optical system configured to form an image to be displayed, an eyepiece optical system configured to provide the image formed by the image forming optical system to a pupil of an observer, and an image shifting optical system disposed on an optical path between the image forming optical system and the eyepiece optical system, the image shifting optical system being configured to shift the image formed by the image forming optical system in a direction perpendicular to an optical axis, wherein the image shifting optical system includes a first optical member having a first focal length and a second optical member having a second focal length, and wherein a distance between the first optical member and the second optical member along the optical axis is equal to a sum of the first focal length and the second focal length.
