P.98: Novel Composite Photo‐alignment Layer for Ferroelectric Liquid Crystal Display

Abstract

Abstract A novel composite photo‐alignment layer for ferroelectric liquid crystal (FLC) displays is explored. The key technique is to introduce a functional liquid crystal polymer into a rewritable azo‐dye material with proper mixing. Bearing good alignment quality derived from the azo‐dye, the composite layer provides strong anchoring energy comparable to that of rubbed polyimide layers. Furthermore, by using a two‐step exposure process, the composite layer shows much better stability than that with a pure azo‐dye material.
