Display device
A first configuration of a display device includes: a first display unit that emits first image light and second image light; a first polarizing half mirror that transmits one of the first or second image light and reflects the other; a first reflective mirror on an optical path of the first polarizing half mirror; and a first λ/4 plate between the first reflective mirror and the first polarizing half mirror. A second configuration includes: a second display unit that emits third image light and fourth image light; a half mirror; and a third reflective mirror that reflects, toward the half mirror, the third image light reflected by the half mirror. A third configuration includes: a second display element; and a first reflector that reflects fifth image light from the second display element. The first reflector includes reflective surfaces for forming display images based on the fifth image light.
1 . A display device comprising:
a second display unit that emits third image light from a third region and fourth image light from a fourth region;
a half mirror including one end portion disposed at a boundary between the third region and the fourth region; and
a third reflective mirror that reflects, toward the half mirror, the third image light emitted from the third region and reflected by the half mirror,
the half mirror is oriented to direct the third image light and the fourth image light in a same direction when transmitting the third image light from the third reflective mirror and reflecting the fourth image light emitted from the fourth region.
2 . The display device according to claim 1 ,
wherein the half mirror is a polarizing half mirror, and
a fourth λ/4 plate is disposed between the third reflective mirror and the polarizing half mirror.
3 . The display device according to claim 1 ,
wherein the display device further comprises:
a driver that causes at least one of the half mirror or the third reflective mirror to operate.
4 . The display device according to claim 1 ,
wherein the second display unit does not allow emission of the third image light and the fourth image light from the boundary between the third region and the fourth region.
