发明名称 LIQUID CRYSTAL DISPLAY DEVICE
摘要 A liquid crystal display comprising a lateral electric field system liquid crystal panel including a liquid crystal layer having orientation dependent on an electric field parallel with the substrate surface, first and second polarizing plates sandwiching the liquid crystal panel, a first optical film interposed between the first polarizing plate and the liquid crystal panel, and a second optical film interposed between the second polarizing plate and the liquid crystal panel. The first optical film includes a phase difference film (A1) having a relation of nz>nx>=ny, and a phase difference film (B) having an in-plane phase difference (Re) of 200-300 nm, a relation of nx>nz>ny and a three-dimensional refractive index with the Nz coefficient controlled to satisfy 0.3nx>=ny, and the phase delay axis of the phase difference film (B) is parallel with or perpendicular to the absorption axis of the first and second polarizing plates. The liquid crystal display exhibits a high contrast ratio over a wide range.
