Abstract
Abstract Microlens effects have been obtained in homogeneously aligned liquid crystal cells prepared using a hole-patterned electrode and a plane electrode. In the asymmetric electrode structure, an axially symmetric non-uniform electric field is produced and a radial distribution of refractive indices can be obtained by the molecular orientation effects in the non-uniform electric field. However, a disclination line which makes the optical properties worse is observed in the homogeneously aligned microlens when a voltage is applied across the cell. In order to improve the lens properties, hybrid-aligned liquid crystal microlens cells are prepared. Their optical properties are investigated and discussed in terms of a molecular orientation model in the non-uniform electric field of the hybrid-aligned cell.
