| titleOfInvention | Retardation film, composite polarizing plate, polarizing plate and liquid crystal display device |
| abstract | PROBLEM TO BE SOLVED: To provide a frontal retardation and optical biaxiality suitable as an optical compensation member, high durability without substantial deterioration of optical compensation physical property even under heating, and a long display image of a liquid crystal display device. To provide a retardation film capable of maintaining high quality over a period. A film made of an amorphous resin (A) and a thermoplastic elastomer resin (B) substantially exhibiting a phase separation form with respect to the amorphous resin (A) is formed at least in the longitudinal direction or the width direction. A retardation film obtained by stretching in one direction, the rate of change of the front retardation R0 defined by the following formula (1) with respect to the initial value before heat treatment after the film is treated at 80 ° C. for 1000 hours Is within 2%, the rate of change of the thickness direction retardation Rth defined by the following formula (2) after the same heat treatment with respect to the initial value before the heat treatment is within 3%, and the front retardation R0 is A retardation film having a thickness in the range of 20 to 200 nm and a thickness direction retardation Rth in the range of -200 to 300 nm. R0 = (nx−ny) × d (1) Rth = ((nx + ny) / 2−nz) × d (2) (Where, nx: maximum refractive index in the film plane, ny: refractive index in the direction perpendicular to the nx direction in the film plane, nz: refractive index in the film thickness direction, d: average thickness of the retardation film) [Selection figure] None |
