Abstract
The head-mounted display device includes a display element, a light guide prism that, in a state of use, guides a regular image light beam from the display element to an exit surface in front of the user's eye, and a support that secures the display element and the light guide prism with respect to the user's head. On at least one side along the optical axis of the regular image light beam, the light guide prism includes at least one first-type inclined surface at a position outside of the region through which the regular image light beam from the display element passes, and the first-type inclined surface is formed to be inclined so as to cause light incident on the first-type inclined surface from a direction along the optical axis of the regular image light beam to be reflected and emitted to the outside of the user's eyeball.
