Title:
MULTILAYER FILM, MANUFACTURING METHOD, CIRCULAR-POLARIZING PLATE, ANTIREFLECTIVE FILM, AND ORGANIC ELECTROLUMINESCENCE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/094485
Kind Code:
A1
Abstract:
The present invention is: a multilayer film for an organic electroluminescence display device, wherein the multilayer film is provided with a phase difference film and a barrier layer provided directly to the surface of the phase difference film, the phase difference film includes one or more layers of a resin A as layers directly in contact with the barrier layer, the resin A includes a crystalline polymer A having a melting point of 250°C or higher, the in-plane retardation Re of the layers of the resin A measured at 23°C by light having a wavelength of 590 nm has a specific value, and the absolute value of the photoelastic coefficient thereof is 2.0×10-11 Pa-1 or less; a method for manufacturing the multilayer film; and an application for the multilayer film.
