Phase difference film laminate, method for producing phase difference film laminate, and method for producing phase difference film

摘要

A P1 layer comprising a resin p1 containing a polyphenylene ether having a positive intrinsic birefringence value and a polystyrene polymer having a negative intrinsic birefringence value and having a syndiotactic structure, and an acrylic provided in contact with the P1 layer A retardation film laminate formed by stretching a film before stretching having a P2 layer comprising a resin or a resin p2 containing an alicyclic structure-containing polymer, wherein the content of the polyphenylene ether / the polystyrene in the resin p1 The phase difference film laminated body whose weight ratio of content of a type | system | group polymer is 35 / 65-45 / 55; its manufacturing method; And the manufacturing method of retardation film using the same.
