Multilayer film, manufacturing method, circularly polarizing plate, antireflection film, and organic electroluminescence display device

摘要

A multilayer film for an organic electroluminescence display device, comprising a retardation film and a barrier layer provided directly on the surface of the retardation film, the retardation film as a layer in direct contact with the barrier layer, The resin A includes one or more layers of resin A, the resin A includes a crystalline polymer A having a melting point of 250 ° C. or higher, and the layer of the resin A is an in-plane measured with light having a wavelength of 590 nm at 23 ° C. A multilayer film in which the retardation Re is a specific value and the absolute value of the photoelastic coefficient is 2.0 × 10 −11 Pa −1 or less; its production method; and its use.
