Abstract

Defect free homogeneous alignment of ferroelectric liquid crystals in the surface stabilized configuration remains challenging to obtain even over the relatively small area of liquid crystal on silicon microdisplays. The limitations of the conventional rubbed polymer alignment technique are discussed and the benefits brought by recent advances in backplane post-processing are demonstrated in realistic conditions. The potential of the linearly photopolymerized photoalignment technique are highlighted in terms of alignment quality, susceptibility to zigzag defects, and electro-optical performances.
