Abstract:
A head mounted display device comprising:a light source for generating and irradiating light; image generating means for generating an image from the light irradiated from the light source; an image forming lens unit for primarily forming the image generated by the image generating means; first light branching means for transmitting and reflecting the image generated by the image generating means, wherein the first light branching means branches the light into two light paths; first light path converting means for converting a traveling path of the image reflected from the first light branching means; a first reflecting mirror on which the image received from the first light path converting means is reflected toward an eye of a user; second light branching means, disposed on the light path between the first light path converting means and the first reflecting mirror, for changing a traveling path of the image incident upon the second light branching means; second light path converting means for converting the traveling path of the image transmitted through the first light branching means; a second reflecting mirror on which the image received from the second light path converting means is reflected toward the other eye of a user; and third light branching means, disposed along the light path between the second light path converting means and the second reflecting mirror, for changing the traveling path of the image incident upon the third light branching means.
