Abstract

Abstract : The color shift of 4‐domain polymer‐stabilized (PS)‐vertical alignment (VA) in oblique viewing directions is a severe problem so that a 8‐domain PS‐VA is required to suppress the color shift. We propose a novel approach to form the 8‐domain by controlling surface polar anchoring energy and patterned electrode width in two regions of a pixel. The gamma distortion index (GDI) was reduced by about 23% and 8% compared to standard 4‐domain at polar angles of 30° and 60° at an azimuthal angle of 0°, respectively.
