<P>PROBLEM TO BE SOLVED: To provide a thin optical laminated body excellent in durability and optical uniformity. <P>SOLUTION: In the optical laminated body including: an A layer made of a resin A whose intrinsic birefringence value is negative; and a B layer made of a transparent resin B, ¾the transverse plane retardation of the A layer¾>¾the transverse plane retardation of the B layer¾ is allowed to satisfy, the total thickness of the A layer and the B layer is ≤60 μm, the ratio of the thickness of the A layer to the total thickness of the A layer and the B layer exceeds 40%, and the total draw ratio reaches ≥2.3 times. <P>COPYRIGHT: (C)2011,JPO&INPIT |
