Abstract
imagelight and outside light are viewed to overlap in a half mirror layer which is a semi-transmissive reflection unit from a state in which a polarization property of the outside light is canceled by a depolarization member disposed more outside than a light-guiding region of the imagelight.
Claims13
A transmissive display apparatus that causes outside light and image light from a video element to be viewed to overlap, the display apparatus comprising:
- a semi-transmissive reflection unit that performs partial reflection and transmission of the outside light and the image light while the outside light and the image light have a polarization property;
- and
- a depolarization member that is disposed in a region more outside than a light-guiding region of the image light extending from the video element to an eye assumption position assumed as a position of an eye via the semi-transmissive reflection unit, using the eye assumption position as a criterion, and cancels a polarization state of the outside light passing through the semi-transmissive reflection unit and incident on the eye assumption position.
