Abstract:
A video display device is provided that naturally displays a video without blocking an observer's field of view, and includes the following: a display optical system that displays a video; an ocular optical system that guides video light emitted from the display optical system to the optical pupil of an observer; and a support that supports the ocular optical system upon the light path of video light emitted from the display optical system. The support includes a first support plate and a second support plate that face each other, and the ocular optical system is located between the first support plate and the second support plate. An opening through which the observer's line of sight passes is formed at least partially between the first support plate and the second support plate.
