Mass production of patterned polymerizable liquid crystal devices by roll-to-roll technology

Abstract

Roll-to-Roll fabrication of patterned liquid crystal films and film-based devices is one of the most promising and anticipated LCD technology of today. The constraint of mass production is the suitable alignment process. The problem of high anchoring patterned liquid crystal alignment on plastic substrates has been challenged for over a decade. We solved it. The possibility of R2R fabrication of retarders with custom azimuthal angle, patterned retarders and vortex retarders is demonstrated.
