Phase difference film and its manufacturing method |
| abstract |
PROBLEM TO BE SOLVED: To provide a manufacturing method capable of easily manufacturing a retardation film having a small NZ coefficient, a thin thickness, a high expression of retardation, and easily manufacturing. A retardation film composed of a resin containing a crystalline polymer and having an NZ coefficient of less than 1; and a crystalline polymer having a glass transition temperature of Tg (° C.) and a melting point of Tm (2). A bonding step of bonding a second film to one side or both sides of a first film made of a resin (° C.) to obtain a third film, wherein the second film is in at least one direction at (Tg + 30) ° C. The shrinkage of the third film is 5 to 50%; the third film is heated to Tg ° C. to (Tg + 30) ° C. and shrunk in at least one direction, and the area thereof is shrunk by 5 to 50%. A production method comprising a secondary heating step of obtaining 4 films; a shrinking step; and heating the 4th film to (Tg + 50) ° C. to (Tm-40) ° C. [Selection diagram] Fig. 2 |
