摘要： The invention relates to an optical compensation film for IPS or FFS-mode liquid crystal display devices, having the tilt angle β[°] not equal to zero, β[°] being defined as φ giving the minimum value of retardation R[φ] which is retardation measured for incident light coming in a direction tilted by φ° from a normal line relative to the film-plane, the direction being in a plane including the direction perpendicular to the in-plane slow axis thereof and the normal line; and having retardation along the thickness direction at a wavelength of 550 nm, Rth(550), not equal to zero.

摘要： A liquid crystal display includes: a first polarizer; a liquid crystal cell including a liquid crystal layer containing liquid crystal molecules horizontally aligned to a face of a substrate; and a second polarizer. The liquid crystal display further includes a first optical compensation film disposed between the first polarizer and the liquid crystal cell, an absorption axis of the first polarizer, an optical axis of the first optical compensation film, and an optical axis of the liquid crystal layer being parallel to each other in a view of the liquid crystal cell in a direction orthogonal to the face of the substrate of the liquid crystal cell. The optical axis of the liquid crystal layer of the liquid crystal cell and the optical axis of the first optical compensation film have a tilt angle from the face of the substrate of the liquid crystal cell in a same direction.
