Abstract: A liquid crystal panel having improved contrast ratio in an oblique direction and good display evenness without causing shift or unevenness in retardation values due to shrinkage stress of a polarizer or heat of backlight is provided. A liquid crystal panel according to an embodiment of the present invention includes: a liquid crystal cell; a polarizer arranged on both sides of the liquid crystal cell; a first optical element arranged between one polarizer and the liquid crystal cell; and a second optical element arranged between the other polarizer and the liquid crystal cell, wherein: the first optical element comprises a retardation film containing a norbornene-based resin and satisfying the following expressions (1) and (2); and the second optical element has substantially optical isotropy: 240 nm?Re[590]?350 nm??(1) 0.20?Rth[590]/Re[590]?0.80.

Abstract: A method for producing a roll of an optical compensation film, in the effective width of which an angle of the slow axis in the film face with the width direction of the film is within the range of ±1° and an angle of the fast axis in the film face with the length direction of the film is within the range of ±1°, wherein the angle of the fast axis in the film face with the length direction is cyclically varied by a cycle of from 1.5 m to 500 m in the length direction of the film and the minimum amplitude of the variation is within the range of from 0.1° to 1°.
