Abstract
Provided is a wide field of view head mounted display device capable of presenting 120 degree field of view per one eye and 180 or more by both eyes horizontally while keeping resolution at least to the same extent of the conventional art. The wide field of view head mounted display device includes: a LCD 1 for displaying an image; a lens 2 for projecting an image displayed on the LCD 1; and a catoptric system with a concave mirror 4 and a convex mirror 3. The LCD 1 and the lens 2, the concave mirror 4 and convex mirror 3 are positioned in a relative relationship to observe by an observing pupil 5 at a predetermined position a virtual image of a beam of reflected light as an incident light on the concave mirror 4 when the light of displayed image on the LCD 1 is projected to the convex mirror 3 through the lens 2 and a reflected light of the projected light at the convex mirror 3 arrives as the incident light at the concave mirror 4.
