Improvement of Reverse Domain in Chiral Hybrid In-Plane Switching Liquid Crystal Mode by the Stacked Alignment Layers

We propose an improved chiral hybrid in-plane switching (CH-IPS) liquid crystal mode with a stable domain. We studied an advanced method for improving the alignment stability of the CH-IPS mode through the surface modification using the stacked alignment layer. The enhanced azimuthal anchoring energy using by the stacked alignment layer, reverse domains of CH-IPS LC mode were disappeared. Consequently, we could obtain the CH-IPS liquid crystal mode with the enhanced brightness compared with the conventional mode
