<P>PROBLEM TO BE SOLVED: To provide a laminated optical film having an excellent optical compensation function by successfully making a film of an inorganic layered compound. <P>SOLUTION: The laminated optical film includes a polarizing plate and a retardation layer formed of a water-dispersed adhesive composition containing the inorganic layered compound. Preferably, the retardation layer has relations expressed by a formula (1) 0.94≤R45[450]/R45[550]≤1.06 and a formula (2) 0.94≤R45[650]/R45[550]≤1.06, wherein R45[450], R45[550] and R45[650] represent phase difference values measured at 45° from a normal direction of the layer at 23°C and at wavelengths of 450 nm, 550 nm, and 650 nm respectively. <P>COPYRIGHT: (C)2011,JPO&INPIT |
