Abstract:
A virtual image display apparatus includes a video image display element which generates video image light, a light guiding member which includes a plurality of optical surfaces and guides the video image light by reflecting on inner surface side, and an optical device portion such as a projector lens through which the video image light passes when the video image light is made to foe incident on the light guiding member. Here, the light guiding member is a block-shaped member including a pair of facing first and third surfaces which extend substantially in parallel with each other and fully reflect the video image light, and first reference optical axis of the optical device portion on a light emitting side extends in a direction in which the first reference optical axis forms an obtuse angle with respect to a traverse reference axis corresponding to an eye alignment direction.
