Patterned alignment layers by capillary force lithography for multi-domain liquid crystal structures

Abstract

We proposed a soft-lithographic technique for patterning liquid crystal (LC) alignment layers. It was demonstrated that a thermoplastic polystyrene layer was patterned on a thermally stable polyimide layer via pressure-assisted capillary force lithography. The patterned surface provided multi-directional LC alignment condition simply after a unidirectional rubbing process.
