Abstract: An image relay optical system is provided with an optical coupling member before incidence of image light on a light guide member. Among a first light incident surface, a coupling member reflecting surface, and a first light emitting surface provided in the optical coupling member, the coupling member reflecting surface and the first light emitting surface are curved surfaces. Therefore, a large bright virtual image with reduced aberration can be displayed.

Abstract: A thickness of a tapered part provided at the deeper side (−X side) in a light guide direction of a light transmission member is smaller toward the deeper side, and thus, a reflection angle of ghost light that has passed through a fourth reflection surface provided with a half mirror layer and reached the light transmission member gradually becomes smaller within the tapered part and no longer satisfies a total reflection condition, and the light is ejected to the outside in the position diverging from an eye of an observer. That is, the tapered part may prevent the ghost light from reaching the eye and good see-through observation can be realized.

Abstract: In regard to a second direction (combination direction) that is turned back by a reflection at the time of light-guiding, a projective optical system has an emission opening width larger than an opening width of a third reflective surface, such that it is possible to prevent a partial deficiency of image light when the image light emitted from the projective optical system is incident to the third reflective surface from occurring, and thereby it is possible to prevent the occurrence of deficiency of an image or a large variation in brightness.
