PROBLEM TO BE SOLVED: To provide a laminate film for optical compensation having an NZ coefficient of 0.3 to 0.7 and excellent optical compensation characteristics such as a high ray transmittance and a small haze value.SOLUTION: The laminate film for optical compensation comprises a film using a fumaric acid diester resin including a diisopropyl fumarate residue unit and a fumaric acid diester residue unit having a 1-2C alkyl group, laminated with a uniaxially stretched film. The film thickness of the resin film layer and an out-of-plane retardation (Rth) measured at a wavelength of 550 nm are in such a relation that the retardation in an absolute value is 4.0 nm or more per unit film thickness (μm); The uniaxially stretched film layer shows an in-plane retardation (Re) of 50 to 300 nm measured at a wavelength of 550 nm; and the laminated film for optical compensation has an NZ coefficient of 0.3 to 0.7. |
