<P>PROBLEM TO BE SOLVED: To provide an optical laminated film that contributes to improvement of viewing angle characteristics in a homogeneous alignment mode liquid crystal display device without causing decrease and unevenness of front contrast ratio. <P>SOLUTION: An optical laminated film includes a B layer satisfying the following three formulas (Ib)-(IIIb), and a C layer satisfying the following two formulas (Ic) and (IIc), where the absolute value ¾ΔSP value¾ of the difference between respective SP values (that are calculated on the basis of Hoy method) of main components of the B layer and C layer is 2.6 or more and 10.0 or less. (Ib): 1.0≤Nz≤3.0, (IIb): 70 nm≤Re (550), (IIIb): 0 nm≤Rth (550)≤200 nm, (Ic): Re (550)≤10 nm, (IIc): -200 nm≤Rth (550)≤-50 nm. <P>COPYRIGHT: (C)2013,JPO&INPIT |
