ABSTRACT:
An in-plane switching liquid crystal display device is designed in such a way that an angle defined by the lengthwise direction of a common electrode and a pixel electrode and a rubbing direction of an alignment layer is set to 10 to 20°, a cell gap d is set to 2.7 μm or smaller, the dielectric anisotropy Δ∈ of a liquid crystal constituting a liquid crystal layer is set to 8 to 20, a white voltage Vwhiteto be applied to the pixel electrode when displaying white is set to 4 to 7 V, and the white voltage Vwhite(V), the dielectric anisotropy Δ∈ of the liquid crystal, the cell gap d (μm) and an interval L (μm) between the common electrode and the pixel electrode satisfy the following expression11.8>Vwhited-0.6×L0.5×Δɛ-0.5>9.8.
