Patterning of liquid crystal alignment layers using selective dewettingprocess in a thermoplastic polymer film

摘要

We proposed a soft-lithographic method forrnaligning a liquid crystal (LC) in patterned azimuthalrnorientations. It is demonstrated that a thermoplasticrnpolystyrene layer is patterned from a thermally stablernpolyimide layer via pressure-assisted capillary forcernlithography, which provides multidirectional LCrnalignment condition simply followed by arnunidirectional rubbing process.
