“…This asymmetry negatively affects the viewing angle properties such as the light leakage, color shift, and grayscale inversion in the specific viewing angle direction [5,6]. To enhance the viewing angle properties of the single-domain planar mode, many optical compensation techniques have been proposed [7][8][9][10][11][12][13][14][15]. These optical compensation methods can reduce the light leakage and remove the grayscale inversion.…”

We demonstrated the pretilt angle effect on the viewing angle properties of a single-domain fringe-field switching (FFS) liquid crystal (LC) mode. By performing the Póincare sphere analysis, we investigated, in detail, the origin of the viewing angle asymmetry that exists in the single-domain FFS LC mode both in the field-on and field-off states. Using this analysis, we confirmed that the pretilt angle reduces the viewing angle symmetry in the single-domain FFS LC mode. Finally, we examined the effect of a zero pretilt angle on the viewing angle symmetry by evaluating real single-domain FFS LC cells.
