Title:
RETARDATION FILM, POLARIZING PLATE, AND IMAGE DISPLAY APPARATUS
Document Type and Number:
Japanese Patent JP2014170068
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a retardation film produced by stretching a resin composition which has high thermal decomposition resistance characteristics of the resin composition, and ensures compatibility with polymers contained therein.SOLUTION: A retardation film is produced by stretching a resin composition (C) containing 75 mass% or more and 90 mass% or less of a copolymer (A) including an N-substituted maleimide unit and a styrene-based unit as structural units, and 10 mass% or more and 25 mass% or less of polyphenylene ether (B). A ratio of the N-substituted maleimide unit to the total structural units of the copolymer (A) is 10 mass% or more and less than 35 mass%. The N-substituted maleimide unit is, for instance, at least one selected from an N-cyclohexylmaleimide unit, an N-phenylmaleimide and an N-benzylmaleimide.
