Paper Abstract

Liquid crystal (LC) director distributions and optical phase profiles in LC micro-lens-array (LC-MLA) are studied by using a three-dimensional (3D) numerical calculation method. The LC-MLA design employs twodivided and tetragonally-patterned electrode structure in a flat nematic LC cell. The possibilities of prism and lenslike phase difference distributions in the rectangular aperture region of the LC-MLA are discussed. The LC molecular orientation distributions in the rectangular region can be estimated and its phase profile can be predicted fairly well by the calculations.
