Abstract
A head-mounted display according to the present disclosure includes an imaging light generating device that emits imaging light, and a half mirror that reflects the imaging light and transmits external light. The imaging light is incident on the half mirror as light of a predetermined polarization state, and, with respect to the light of the predetermined polarization state, reflectance of a first polarization by the half mirror is lower than reflectance of a second polarization by the half mirror.
Claims9
A head-mounted display comprising:
- an imaging light generating device configured to emit imaging light;
- and
- a half mirror configured to reflect the imaging light and transmit external light, wherein
- the imaging light is incident on the half mirror as light of a predetermined polarization state, and
- with respect to the light of the predetermined polarization state, reflectance of a first polarization by the half mirror is lower than reflectance of a second polarization by the half mirror.
