15.2: Distinguished Paper: LC GRIN Lens Mode with Wide Viewing Angle for Rotatable 2D/3D Tablet

To widen the vertical and horizontal angular ranges where the lens performs well, the off-axis performance of an LC GRIN lens is analyzed, and the detailed conditions of structure are established. We have developed a rotatable 2D/3D display whose 3D viewing azimuth angle is over 30 degrees in both landscape and portrait orientations.
