Abstract
A virtual image display apparatus includes a display device serving as an image forming unit, an image optical system including a first mirror member serving as an outer mirror member and receiving imaging light from the display device, and a partially reflecting type mirror portion reflecting imaging light emitted from the image optical system toward a position of an exit pupil. The first mirror member serving as the outer mirror member and the partially reflecting type mirror portion are integrated.
Claims24
A virtual image display apparatus comprising:
- an image forming unit;
- an image optical system including an outer mirror member and configured to receive imaging light from the image forming unit;
- a partially reflecting type mirror portion configured to reflect imaging light emitted from the image optical system toward a position of an exit pupil;
- a body cover member configured to cover the image forming unit and the image optical system;
- and
- a protective member formed of a material having optical transparency, and extending from a coupling portion linking the outer mirror member and the partially reflecting type mirror portion, the protective member being configured to cap the body cover member, wherein
- the outer mirror member and the partially reflecting type mirror portion are integrated.
A virtual image display apparatus comprising:
- an image forming unit;
- an image optical system including an outer mirror member and configured to receive imaging light from the image forming unit;
- and
- a partially reflecting type mirror portion configured to reflect imaging light emitted from the image optical system toward a position of an exit pupil, wherein
- the outer mirror member and the partially reflecting type mirror portion are integrated,
- the outer mirror member and the partially reflecting type mirror portion respectively correspond to a first reflecting region and a second reflecting region formed at a substrate having a plate shape,
- a total-reflection type mirror film is formed at the substrate in the first reflecting region,
- a partially transmissive type mirror film is formed at the substrate in the second reflecting region,
- the partially transmissive type mirror film and the total-reflection type mirror film are formed at a surface of the substrate at an exit pupil side, and
- the total-reflection type mirror film is layered on the partially transmissive type mirror film at the substrate from inside the first reflecting region to an outer edge of the second reflecting region.
