Abstract:
Provided is a lens unit with which a decrease in the weight and an increase in the definition of VR goggles can be realized, and with which afterimage can be suppressed. A lens unit according to an embodiment of the present invention is used in a display system for displaying an image to a user. The lens unit comprises: a reflective polarization member that reflects light which has been emitted toward the front from a display surface of a display element showing an image and which has passed through a polarization member and a first λ/4 member; an absorptive polarization member that is disposed in front of the reflective polarization member; a first lens unit that is disposed on an optical path between the display element and the reflective polarization member; a half mirror that is disposed between the display element and the first lens unit, and that transmits light emitted from the display element and reflects light which has been reflected by the reflective polarization member back toward the reflective polarization member; and a second λ/4 member that is disposed on an optical path between the half mirror and the reflective polarization member. The first lens unit, the second λ/4 member, the reflective polarization member, and the absorptive polarization member are integrated.
