Patent ID: 10668690

Abstract:
The present invention provides: an optical laminate comprising at least two films, the optical laminate comprising at least a film A satisfying a given condition (1) and a film C satisfying a given condition (2), wherein a retardation value Re(0) observed in a direction of an axis perpendicular to a plane of the optical laminate is 4,000 to 30,000 nm, and a retardation value Re(40) observed in a direction of an axis tilted from the axis perpendicular to the plane of the optical laminate toward a slow axis by 40 degrees in a plane lying perpendicular to the plane of the optical laminate and extending along the slow axis is 4,000 to 25,000 nm, the slow axis being an axis along which refractive index is highest in a plane of the film A; and a display device comprising the optical laminate.
