A novel method to achieving active refractive and diffractive liquid‐crystal microlens arrays is demonstrated. By two‐photon polymerization, liquid‐crystal alignment can be directly generated on curved or planar surface and thus active microlens arrays can be created by fulfilling liquid‐crystal cells. This method provides a new route toward liquid‐crystal microlens arrays.
