To provide a three-dimensional view display using a focus clue in which an address can be designated in a non-exclusive manner.SOLUTION: A three-dimensional view display comprises: a micro display for providing a virtual image to be displayed to a user; an active refraction optical element configured to provide variable refraction force; a relay lens which is arranged between the micro display and the active optical element so that, the micro display and the active optical element are arranged on a conjugation plane of the relay lens 20; a beam splitter arranged between the micro display and the active optical element in a direction for receiving light radiation from the active optical element; and a see-through ocular lens 12 having a selected surface for receiving light radiation from the beam splitter, reflecting the received light radiation to an exit pupil of the system for providing a virtual display optical path, receiving light radiation from a light source other than the micro display, transmitting the light radiation to the exit pupil for providing a see-through optical path.SELECTED DRAWING: Figure 3B
