A laminated optical film including an optical film (1) whose three dimensional
refractive index is controlled so that an Nz coefficient represented with Nz=(nx1-nz1)/(nx1-ny1)
satisfies a relationship of Nz0.9, when a direction where a refractive
index in a film plane gives maximum is defined as X-axis, a direction perpendicular
to X-axis as Y-axis, a thickness direction of the film as Z-axis, and refractive
indexes in each axial direction are defined as nx1, ny1,
and nz1, respectively, and an optical film (2) that is formed
with a material showing optically negative uniaxial property, and being tilting aligned.
The laminated optical film may suppress coloring of the display, and may display
a picture with few tone reversal regions.
