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 cost‐effective novel polarizer replacing WGP for photoalignment of LC but also for photonic component of broadband polarizer from UV to IR.
