METHODS FOR MANUFACTURING LAYERED FILM, POLARIZER, LIQUID-CRYSTAL DISPLAY, AND OPTICAL FILM

摘要

A laminated film having a retardation layer A and a layer B that are formed through solvent co-casting is provided. The layer A has a thickness of 5 to 30μm. The layer B has a higher tensile modulus compared to the layer A. An interlayer peeling force between the layer A and the layer B is 0.05 to 5 N/cm. The laminated film overcomes the deterioration of handling property generally occurring with the reduction of film thickness in solvent casting method.
