Abstract

See full text

A virtual image display device includes: an image light generating device; a projection optical system configured to project image light emitted from the image light generating device; a folding mirror configured to reflect, in an intersecting direction, the image light from the projection optical system; a semi-transmissive mirror configured to reflect a portion of the image light from the folding mirror; and a concave surface mirror configured to reflect, toward the semi-transmissive mirror, the image light reflected at the semi-transmissive mirror to form an exit pupil, in which an optical axis of the image light extending from the image light generating device to the folding mirror is disposed between a first virtual extension plane obtained by imaginarily extending the semi-transmissive mirror and a second virtual extension plane obtained by imaginarily extending the concave surface mirror.
