A method of displaying a multi-view 3D image using a multi-view 3D image display device including an image display panel configured to display a 3D image, a control portion configured to control a viewpoint image of each of 3D pixel lines that provide multiple, at least four, viewpoints, and a viewer eye pupil position tracking system, the method comprising:
- acquiring three dimensional coordinate values of positions of a viewer's eye pupils through the viewer eye pupil position tracking system;
- selecting a first viewpoint and a second viewpoint that are close to centers of the viewer's eye pupils for a viewing zone of a viewpoint for each 3D pixel line by using the three dimensional coordinate values of positions of the viewer's eye pupils acquired from the viewer eye pupil position tracking system through the control portion;
- and
- providing a viewpoint image of one of the viewer's eyes to the first viewpoint and providing a viewpoint image of another of the viewer's eyes to the second viewpoint through the control portion.
