Abstract

We present the status of our research in liquid crystal display (LCD) photo-aligning. We describe the photo-induced order in azo-dye layers and show that photo-aligning methods can provide a controllable pretilt angle and anchoring energy of the liquid crystal cell, as well as its high thermo and UV stability. The photo-aligning of ferroelectric and vertical aligned nematic (VAN) mode is also discussed.
