Abstract

See full text

By rotating each optical member including an image display apparatus by a rotation unit, it is possible to change an aspect ratio and display an image. At this time, the rotation unit rotates a stop having an opening with a shape corresponding to the shape of an emission surface of image light in a video display element which is a video element of the image display apparatus along with the image display apparatus. Accordingly, even when an image with a horizontally long aspect ratio is shown and even when an image with a vertically long aspect ratio is shown, occurrence of stray light can be suppressed. Thus, guiding of the image light by a light-guiding optical system can be maintained in a good state, and thus good image display can be realized.
