<P>PROBLEM TO BE SOLVED: To provide an optical laminate film contributing to improvement in viewing angle characteristics of a liquid crystal display device of a horizontal alignment mode, without inducing decrease in a front contrast ratio and unevenness. <P>SOLUTION: The optical laminate film includes a B layer satisfying the following three formulae (Ib) to (IIIb) and a C layer satisfying the following two formulae (Ic) and (IIc). The absolute value of a difference in a SP value (SP value calculated based on Hoy's method) ¾ΔSP value¾ between the main components of the B layer and the C layer is 1.5 or less. The formulae are (Ib):1.0≤Nz≤3.0, (IIb):70 nm≤Re(550), (IIIb):0 nm≤Rth(550)≤200 nm, (Ic):Re(550)≤10 nm, and (IIc):-200 nm≤Rth(550)≤-50 nm. <P>COPYRIGHT: (C)2013,JPO&INPIT |
