<P>PROBLEM TO BE SOLVED: To provide a retardation film improved in haze and impact resistance. <P>SOLUTION: The retardation film is obtained by stretching an unstretched film having a P1 layer comprising a resin composition p1 containing a resin A whose intrinsic birefringence value is positive and a resin B whose intrinsic birefringence value is negative, and a P2 layer comprising a thermoplastic resin composition p2 disposed in contact with the P1 layer, wherein a polyphenylene ether having a weight average molecular weight of 5,000-10,000 is used as the resin A and a polystyrene resin having a weight average molecular weight of 130,000-300,000 is used as the resin B. <P>COPYRIGHT: (C)2011,JPO&INPIT |
