A laminated optical film comprising a first opt -11 to 6.0 × 10 -11 m 2 /N, and the three dimensional refractive index is controlled, a second optical film (2) showing optically positive uniaxial property that satisfies nx 2 > ny 2 ‰ nz 2 , and a third optical film (3) formed of a material showing optically negative uniaxial property, and the material comprising a part being angularly aligned, and the thickness of the film is 30 to 90µm, 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.
