Phase difference film, manufacturing method thereof, polarizing plate, and display device |
| abstract |
The present invention has a high reliability and a method of producing a retardation film having a small number of display spots and a reverse wavelength dispersion characteristic due to local dependence of phase difference change. The method for producing a retardation film of the present invention satisfies the following formulas (1) and (2): 0.70 < Re1 [450] / Re1 [550] < 0.97‧ ‧ (1) 1.5 × 10 - 3 < Δn < 6.0 × 10-3‧‧‧(2) (In the formula, Re1[450] and Re1[550], respectively, are the in-plane phase difference of the retardation film measured at wavelengths of 450 nm and 550 nm at 23 ° C, Δn The in-plane birefringence of the retardation film measured by the wavelength of 550 nm light) The method of the present invention comprises the steps of: continuously transporting the long polymer film and supplying it; and extending the polymer film in the lateral direction of the transport direction a first shrinking step of shrinking the polymer film in the lateral direction after the stretching step, and a second shrinking step of shrinking the polymer film in the lateral direction after the first shrinking step; wherein, the first shrinking step The shrinkage temperature T1 (°C) in the shrinking step and the shrinkage temperature T2 (°C) in the second shrinking step satisfy the following formula (3): 1<(T1-T2)≦10‧‧(3). |
