Method for producing negative birefringent polymer film |
| abstract |
(57) [Problem] To provide a method for easily producing a negative birefringent film, in which the birefringence index can be easily controlled. SOLUTION: In a polymer film having negative birefringence, the amount of residual solvent contained in the film is changed to control the negative birefringence. The polymer is preferably polyimide or polyetherketone. |
