摘要:
A head-mounted display that guides image light displayed by an image formation unit and focuses the image light on a viewer's side includes a light guide member that angularly converts the image light incident from the image formation unit based on reflection at a plurality of transflective layers, and a light absorption layer is disposed on each of the transflective layers. The light guide member has a light incident surface through which the image light is introduced into the light guide member, a prism reflection surface that is disposed at an end of the light guide member, serves as one of the plurality of transflective layers, and reflects the image light introduced through the light incident surface, and the light absorption layers disposed between the light guide member and the prism reflection surface.
