Improvement of an Azimuthal Anchoring Energy by stacking Photo-alignment Layer onto a Planar Alignment Layer

Abstract

We propose a method to improve an azimuthal anchoring energy in a photo-alignment layer. We stack a photo-alignment layer onto a planar alignment layer, and then, the stacked photo-alignment layer is exposed by linearly polarized UV to improve the azimuthal anchoring energy. Finally, in the fringe-field switching mode, we achieved the fast response time characteristics.
