P‐154: New Carbon Nanotubes UV Polarizer for Photoalignment of Liquid Crystals

Abstract

We propose a unidirectionally aligned multi-layered carbon nanotubes (CNT) as a UV polarizer for LC photoalignment, which can replace wire-grid-polarizer (WGP) with high cost. A 12 multi-layered CNT polarizer exhibits the degree of polarization up to 91%. The fringe-field switching (FFS) LC device made by photoalignment with use of the proposed CNT polarizer exhibit uniform LC alignment in whole area and excellent electro-optics. The work proposes not only costeffective novel polarizer replacing WGP for photoalignment of LC but also for photonic component of broadband polarizer from UV to IR.
