Abstract

A novel composite photoalignment layer for ferroelectric liquid crystal (FLC) displays is explored. The key technique is to introduce a functional liquid crystal polymer into 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. The photostability has been evaluated by the exposure energy needed to rearrange the orientation of SD1 molecules. The photostabilitv is improved by more than 20 times using composited layer compared with pure SD1 material.
