Near-zero pretilt alignment of liquid crystals using polyimide films doped with UV-curable polymer

초록

We propose an alignment method for the near-zero pretilt angle of liquid crystals (LCs) using polyimide films doped with a UV-curable polymer. The near-zero pretilt angle can be obtained by UV curing of reactive mesogen monomers mixed with planar alignment material while a vertical electric field is applied to an LC cell assembled after the rubbing process. We demonstrated that the pretilt angle can be decreased from 2.390 degrees to 0.082 degrees by employing the proposed method. (C) 2015 Optical Society of America
