Topological defects in liquid crystal (LC) phases have attracted much attention in the areas of self‐assembly, and applications including particle manipulation system and template for material micropatterning. Developing reconfigurable periodic topological defect arrays in the nematic LC phase is demonstrated by applying electric field using a crossed‐linear and interdigitated transparent indium–tin–oxide (ITO) electrode on glass substrates. Modulation of the defect patterns is achieved via varying configurations of the electric field and electrode. The individual LC defect can be employed to generate an optical vortex inducer and a particle trapping‐releasing unit, which could be dynamically controlled. This approach would be beneficial to extend the use of LC patterns in lithographic tools and optoelectronic devices.
