Abstract
The viewing zone of the conventional 3D display that uses a lenticular lens determined by the specifications of the lens, and it was difficult to expand because the lens with wider viewing zone has larger aberration. In this study, a method of enlarging the viewing zone by placing the frame on the real image region and narrowing the display width was tried. According to the configuration placing the mirrors on the sides, the viewing zone can be expanded to about b times by making the display width to 1/b. Where b is an integer of 2 or more, we experimented for the case of b=2, 3.
