Surface structures of polymer films with finely controlled molecular alignment have drawn much attention for improving functionality of mechanics and optics. Recently, we have developed a novel photoalignment process triggered by spatially selective photopolymerization. In this study, we investigated formation behavior of peak/valley structures from the detailed molecular alignment in polymer films.
