Abstract In this article, a method for fabricating the patterned liquid crystal photoalignment structures, in a single step, is proposed. A patterned quarter‐wave plate formed by a photoaligned liquid crystalline polymer film is used as a photomask to generate photoaligned micro‐patterns. Whereas other existing alternatives include complicated fabrication scheme, the proposed method provides an edge with simple one‐step alignment. Moreover, the proposed method offers highly accurate, high resolution, multi micro‐pattern alignment with great repeatability and therefore could find application in wide range of photonic and display devices demanding the micro‐patterned, single of multi domain, alignment. In addition, the structure could be used for optical polarization information storage and patterned alignment structure storage, which could easily be reproduced.
