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.
