Abstract

A head-mounted display apparatus is disclosed. The head-mounted display apparatus includes an optical member having a front surface, a rear surface, and a plurality of side surfaces, a display unit adapted to emit a display image toward one of the side surfaces of the optical member, and a reflective structure disposed inside the optical member to reflect the display image emitted from the display unit and to allow the reflected display image to pass and propagate through the rear surface. The image reflected by the reflective structure and delivered to user's eyes is the same irrespective of the coverage of the user's field of view.
