碩士 === 國立臺灣大學 === 光電工程學研究所 === 107 === In this thesis, we use liquid crystal simulation software 2dimMOS to investigate the electric potential of liquid crystal lenses with hole-pattern electrode, hole-pattern with additional electrode and spherical electrode. We analyze the electric potential to determine whether the three kinds of liquid crystal lenses with the lens sizes of millimeters can form a continuous electric potential distribution in the liquid crystal layer and the non-uniform electric field could be generated. The refractive index distribution generated by non-uniform electric field in the liquid crystal layer forms a liquid crystal lens. We further investigate whether the hole-pattern electrode with additional electrode liquid crystal lens and the spherical electrode liquid crystal lens have flat potential distribution between the two adjacent lenses and crosstalk occurs consequently. Fabrication of four sizes of liquid crystal lenses range from micrometers to millimeters is also included. Replication process is used and conductive polymer PEDOT:PSS is applied to form spherical electrode. We assemble flattened spherical electrode with ITO glass with PVA to form liquid crystal lens.
