The conventional liquid crystal displays (LCDs) have been using
optically uniaxial liquid crystal (LC) medium and this often causes a
significant image change at oblique viewing angles. We simulated the
viewing angle properties of the biaxial nematic
(Nb) phase of a bent-core liquid crystal (BLC) and
compared the results with the vertically aligned (VA)- and the in-plane
switching (IPS)-LCDs. The Nb phase of the BLC
showed a smaller transmittance at the dark state as well as a greater
contrast ratio at wide viewing angle. The viewing angle property of the
Nb-mode without any compensation film was slightly
superior to the IPS-mode with the compensation films eliminating the
decross of the polarizers at oblique viewing angle.
