— We have investigated the formation of polymer walls using a patterned electric field for rugged liquid‐crystal (LC) displays. The patterned electric field induces patterned phase separation. The LC molecules segregate in the high‐electric‐field regions, i.e. , pixels, whereas the monomers segregate in the low‐field regions, i.e. , inter‐pixels. Subsequent photo‐polymerization forms polymer walls between the pixels. We discuss the features of polymer walls formed by using this novel method.
