Abstract: A resin film formed of a resin containing a polymer containing an alicyclic structure and having crystallizability, wherein a crystallization degree of the polymer is 30% or more, and a thickness variation Tv of the resin film represented by the following formula (1) is 5% or less. The formula (1) is Tv [%]=[(Tmax−Tmin)/Tave]×100. In the formula (1), Tmax is a maximum value of the thickness of the resin film, Tmin is a minimum value of the thickness of the resin film, and Tave is an average value of the thickness of the resin film).

Abstract: Provided is a resin film having excellent size stability in a high-temperature environment. A resin film formed of a resin containing an alicyclic structure-containing polymer having crystallizability, wherein an absolute value of a thermal size change ratio when the film is heated at 150° C. for 1 hour is 1% or less in any in-plane direction of the film. The alicyclic structure-containing polymer may preferably be a hydrogenated product of a ring-opened polymer of dicyclopentadiene. Also provided is a method for producing the resin film including a step of relaxing strain of the crystallized film while the crystallized. film is kept flat.

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.
