A laminated optical film comprising an optical film(1) obtained by stretching a polymer film comprising a polycarbonate resin and a styrene resin, wherein a photoelastic coefficient is 2.0 x 10<-11> to 6.0 x 10<-11>m<2>/N, and a three dimensional refractive index is controlled, an optical film (2) showing optically positive uniaxial property that satisfies a relationship of nx2 > ny2 SIMILAR nz2, and an optical film (3) formed of a material showing optically negative uniaxial property, and the material being tilting aligned; enables inhibition of coloring of display image for observation of a display picture in a diagonal direction to normal line of a screen, and enables display of an image having little gradation inversion areas, and that has outstanding durability. <IMAGE>
