Abstract
Image formation is performed by using a synthesis optical system, and in a first dichroic film and a second dichroic film that are the synthesis surfaces in the synthesis optical system, a direction in which the cross axis that is the intersecting axis extends corresponds to a direction of alignment of eyes of an observer.
Claims11
A virtual-image display apparatus, comprising:
- a plurality of image elements configured to emit light of different wavelength bands to display an image;
- a synthesis optical system configured to synthesize the light from the image elements to form image light;
- and
- a display optical system configured to allow visual recognition of a virtual image formed by the image light passing through the synthesis optical system, wherein
- in the synthesis optical system, an intersecting axis of a synthesis surface for synthesizing the light from the image elements extends along a direction corresponding to a lateral direction of the formed virtual image.
