ABSTRACT:
A liquid crystal display device of a vertical alignment mode is provided in which a quenching pattern, which is generated by such liquid crystal molecules whose in-plane component of the alignment directions under applied voltage is aligned along the cross nicole directions, is unrecognizable for a user. In the liquid crystal display device of a vertical alignment mode, a liquid crystal layer is has a defined value of d/p between 0.0021×(Vmax)2−0.0458×(Vmax)+0.65 and 0.0021×(Vmax)2−0.0458×(Vmax)+0.50, and a defined value of d·Δn/λ between −0.00026×(Vmax)3+0.016×(Vmax)2−0.2281×(Vmax)+2.124 and −0.00026×(Vmax)3+0.016×(Vmax)2−0.2281×(Vmax)+1.7603, where Vmax [V] is the maximum applied effective voltage applied to the liquid crystal layer.
