An optical film for VA, IPS and OCB, which improves color shift depending on a high contrast and a viewing angle direction during black display, does not change a display level even when a change in temperature, humidity, or the like occurs. A manufacturing method thereof, and a polarizing plate using the optical film. The maximum X-ray diffraction intensity in the range of 2θ = 10-40 ° in the longitudinal direction of the film and the maximum X-ray diffraction intensity in the range of 2θ = 10-40 ° in a direction substantially perpendicular to the longitudinal direction of the film. And the value obtained by dividing the larger value by the smaller value is 1.6 or more. Of the tensile elastic modulus in the film longitudinal direction and the tensile elastic modulus in the direction substantially perpendicular to the film longitudinal direction, the value obtained by dividing the larger value by the smaller value is 1.3 or more. Optical film. [Selection figure] None |
