| Outline of Final Research Achievements |
An LC lens with good lens qualities has been prepared using a hole-patterned electrode, an inner circular electrode separated from the LC layer with an insulating glass substrate, and a common electrode. The LC lens is driven by two ac voltages applied across each electrode and the common electrode. The hole-patterned area acts as a lens.
In this study, we developed a novel LC lens with several ring electrodes and highly resistive thin film for enlarging a phase retardation profile and wide variable range of lens power with the effective lens diameter. The proposed LC lens exhibits a focusing range from the concave lens to convex lens property inside convex lens property (conversely the convex lens ~ concave lens property inside concave lens property).
