The light efficiency of most well‐known nematic liquid crystal (LC) modes, such as twisted nematic and in‐plane switching, depends only on the cell retardation value, irrespective of the cell gap and dielectric anisotropy of the LC. Interestingly

The fringe-field switching (FFS) mode is a representative mode exhibiting both a wide viewing angle and high transmittance due to the in-plane rotation of the liquid crystal (LC) director. However, it shows a color shift in off-normal directions, esp
