    • A liquid crystal display in which a multilayer optical film obtained by drawing a polymer film containing a polycarbonate-based resin and a styrene-based resin and consisting of an optical film (1) having a photoelastic coefficient of 2.0x10^-11~6.0x10^-11 m2/N and three-dimensional refractive index controlled such that the Nz coefficient expressed by Nz=(nx1-nz1) /(nx1-ny1) satisfies a relation Nz=80 nm, an optical film (2) satisfying a relation nx2>ny2≒nz 2 and exhibiting optically positive uniaxiality, and an optical film (3) formed of a material exhibiting optically negative uniaxiality and including an obliquely oriented part is arranged on both sides of a liquid crystal cell along with a polarizing plate. In such a liquid crystal display, coloring of the displayed image is suppressed even when it is viewed from a direction oblique to the direction normal to the screen, and an image where tone reversal area is reduced can be displayed while exhibiting excellent durability.

    • A polarizing plate with an optical compensation layer capable of appropriately preventing leakage of light in black display while preventing thermal unevenness and contributing to reduction in thickness, and an image display employing it. The polarizing plate with an optical compensation layer comprises a polarizer, a first optical compensation layer, a second optical compensation layer, and a third optical compensation layer arranged in this order. The first, second and third optical compensation layers respectively have a predetermined absolute value of photoelastic coefficient, refractive index distribution, in-plane phase difference and/or phase difference in the thickness direction, respectively. The angle between the absorption axis of the polarizer and the lag axis of the first optical compensation layer is 10-30°, the angle between the absorption axis of the polarizer and the lag axis of the second optical compensation layer is 70-95°, and the angle between the absorption axis of the polarizer and the lag axis of the third optical compensation layer is 70-95°.
