| titleOfInvention | Optical film, composite optical film and manufacturing method |
| abstract | An optical film capable of exhibiting a favorable effect as a three-dimensional retardation film, exhibiting an effect of suppressing deterioration of a display device, and being easily produced, and a production method thereof. offer. An optical film comprising a layer of a resin (a) containing a crystalline polymer, having a light transmittance of 5% or less at a wavelength of 380 nm, and an Nz coefficient of greater than 0 and less than 1. A step (I) of obtaining a film (I) comprising a layer of a resin (a) and containing an ultraviolet absorber, and one or both surfaces of the film (I) are brought into contact with a solvent to obtain a thickness of the film (I) a step (II) of changing the refractive index in the direction to obtain the film (II). [Selection figure] None |
