Abstract:
Provided is a phase difference film formed of a resin containing a polymer having crystallizability, and having an NZ factor of less than 1. A production method of the phase different film includes: bonding a second film to one or both surfaces of a first film formed of a resin containing the polymer having crystallizability and having a glass transition temperature Tg (° C.) and a melting point Tm (° C.), to obtain a third film, the second film having a shrinkage percentage in at least one direction at (Tg+30)° C. of 5% or more and 50% or less; heating the third film to Tg° C. or higher and (Tg+3)° C. or lower to obtain a fourth film; and heating the fourth film to (Tg+50)° C. or higher and (Tm−40)° C. or lower.

Claim (Index 6):
A method for producing the phase difference film according to  claim 1 , comprising:\n (1) a bonding step of bonding a second film to one or both surfaces of a first film formed of a resin containing the polymer having crystallizability and having a glass transition temperature Tg (\u00b0 C.) and a melting point Tm (\u00b0 C.), to obtain a third film, the second film having a shrinkage percentage in at least one direction at (Tg+30)\u00b0 C. of 5% or more and 50% or less; (2) a shrinking step of heating the third film to Tg\u00b0 C. or higher and (Tg+3)\u00b0 C. or lower, to cause shrinkage of the third film in at least one direction so that an area thereof is decreased by 5% or more and 50% or less, to obtain a fourth film; and (3) a secondary heating step of heating the fourth film to (Tg+50)\u00b0 C. or higher and (Tm\u221240)\u00b0 C. or lower.
