Abstract

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.
