Title:
FILM WITH SUPPRESSED PHASE DIFFERENCE IN THICKNESS DIRECTION
Document Type and Number:
Japanese Patent JP2022012523
Kind Code:
A
Abstract:
To provide a film of which phase difference in a thickness direction can be reduced by forming a proper structural polymer for the film even if the film was made in a simple process.SOLUTION: The film is made of a resin composition including a polymer chain (A) having a unit derived from diene and/or olefin and a polymer chain (B) having a unit (b1) derived from a (meth) acrylic monomer. An NZ coefficient of the film determined by the expression: NZ coefficient=(Rth/Re)+0.50 (in which Re denotes an in-plane phase difference (nm) when the wavelength is 589nm and Rth denotes a thickness-direction phase difference (nm) when the wavelength is 589nm) is at least 0.35 and is smaller than 1.0.SELECTED DRAWING: None
