Virtual image display apparatus

摘要

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.

主权项

1. A virtual image display apparatus comprising:
a video image element which generates video image light; a light guiding member which includes a plurality of optical surfaces and guides the video image light from the video image element by reflecting the video image light on an inner surface side thereof; and an optical device portion through which the video image light passes when the video image light from the video image element is made to be incident on the light guiding member, wherein:
the light guiding member is a block-shaped member which includes, as the plurality of optical surfaces, a pair of facing planar optical surfaces which extend substantially in parallel with each other and fully reflect the video image light, andan optical axis of the optical device portion on a light emitting side thereof extends in a direction in which the optical axis forms an obtuse angle from a light incident portion of the light guiding member with respect to a traverse reference axis in parallel with an eye alignment direction.
