A laminated optical film including a first optical anisotropic layer, and a second optical anisotropic layer, wherein Rth1 of the first optical anisotropic layer, and Rth2 of the second optical anisotropic layer satisfy one of Relationships (1) and (2), and &Dgr;Rth1≧0 nm and &Dgr;Rth2≦̸0 nm   (1) &Dgr;Rth1<0 nm and &Dgr;Rth2>0 nm   (2) wherein a retardation value Rth of the laminated optical film as a whole in its thickness direction satisfies 50 nm≦̸Rth≦̸500 nm, where &Dgr;Rth1 denotes a value obtained by calculating the expression Rth1 (at a temperature of 50° C.)−Rth1 (at a temperature of 25° C.) concerning the first optical anisotropic layer, and &Dgr;Rth2 denotes a value obtained by calculating the expression Rth2 (at a temperature of 50° C.)−Rth2 (at a temperature of 25° C.) concerning the second optical anisotropic layer.
